During the Q and A portion of our call, Ray Ritchie, Senior Executive Vice President and our regional management teams will be available to address any questions. I would now like to turn the call over to Owen Thomas for his formal remarks.
Thank you, Sarah, and good morning, everyone. Today, I'm going to depart from my typical organization of remarks and instead summarize all the reasons why we are confident in Boston Properties' future prospects and enthusiastic about the company's growth potential at this unique point in time. As part of my comments, I will address accomplishments and challenges of the past year, current capital and property market conditions as well as Boston Properties' capital allocation decisions and strategy. So why BXP and why now? I will begin with 3 points on Boston Properties' potential for income growth, both in the short and long term from where we closed out 2020.
First, our variable income streams will recover. Over the next 24 months, Boston Properties will likely enjoy one of its most significant and predictable improvements in economic conditions and leasing activity as we witness the end of the COVID-nineteen pandemic. 2 vaccines with high efficacy rates have been FDA approved, 5.8% of Americans have already received at least one dose of the vaccine, the more easily refrigerated Johnson and Johnson vaccine is near approval and health authorities are advising that anyone who wants to be vaccinated will be accommodated by this summer. The Biden administration is aggressively pursuing a more rapid vaccine rollout as well as economic stimulus to help bridge the economic damage caused by the pandemic. Given the herd immunity created by a high percentage of the population either recovered from infection and or vaccinated, infections will likely drop precipitously in the middle of the year.
We are all anxious to come out of isolation and return to our normal lives. So as the infection rate drops, economy will reopen and individuals will return to offices, restaurants, shops, theaters and travel. Approximately $97,000,000 of Boston Properties FFO decrease in 2020 came from the variable income streams of parking, our single hotel and retail customers, all of which were devastated by the lockdown. And we will likely see a strong recovery in these variable income streams in the near term as the economy reopens. 2nd, Boston Properties office portfolio is stable.
We have been collecting through the pandemic over 99% of our office rents owed, demonstrating the quality of our buildings and office tenants. Only 7.1% of our leases rollover this year, and we experienced 20% roll ups on average the last 3 years, providing a cushion for decreases in market rent caused by the pandemic. We have signed over 600,000 square feet of leases on currently vacant space that will experience rent commencement in 2021. We expect the noncash charges experienced in 2020 for accrued rent balances to diminish, if not cease, in 2021. We are now recognizing rent on a cash basis for all theater and co working tenants as well as the vast majority of retail credits we consider at risk.
We will also be delivering in whole or part 3 assets into service this year, 100 Causeway, 159 East 53rd Street and 200 West Street, just under 1,000,000 square feet in the aggregate and 95% leased. 3rd, Boston Properties has significant external growth drivers, which are readily quantifiable over the next 4 years. We currently have under development and redevelopment 7 projects comprising 3,700,000 square feet and $2,200,000,000 in total investment. These projects are 88% pre leased, fully funded with cash on our balance sheet and projected to generate cash yields on cost at stabilization of approximately 7%. In addition, we recently delivered 3 Class A urban apartment complexes in Boston, Reston and Oakland with an aggregate of 13 50 units that are only 56% leased and have substantial income upside as the economy reopens.
We expect the income from delivering this development pipeline to add 3 point 4% annually to our FFO growth over the next 4 years. We also anticipate starts this year of over $800,000,000 the majority of which are new life science developments and conversions. And lastly, we own or control land aggregating over 16,000,000 square feet of potential office, lab and residential development, which we will commence as dictated by market conditions. Now my next points relate to our business model and strategy. A core strategic principle for Boston Properties is to build, acquire and own high quality buildings.
Our portfolio is dominated by Class A urban assets, many among the leading buildings in their respective markets, such as Salesforce Tower, the General Motors Building, 200 Clarendon Street and Kendall Center. Higher quality buildings stay more occupied and perform better in times of recession as certain customers take advantage of lower rents to upgrade their space. For example, VTS reported from their database that tours for Class A buildings in New York City went from 38% of total before the pandemic to 54% during the pandemic. Another hallmark of our quality strategy is market selection as we believe in the long term health and attractiveness of our coastal gateway markets. We acknowledge the economic damage to local businesses and city budgets the pandemic has wrought as well as individual relocations to lower tax jurisdictions.
But we remain confident in the attractiveness of our target markets for two basic reasons: the clustering of knowledge workers and increased barriers to new supply. The cities where we currently and aspire to operate, New York, San Francisco, Boston, Washington, D. C, Los Angeles and Seattle have unmatched educational, cultural and civic resources, which attract the leading clusters of knowledge workers in the U. S, particularly in computer science and life sciences. Knowledge workers have more job opportunities and are more productive when working with others in clustered environments.
Future job growth in office demand is going to be driven in the technology and life science fields where our target markets have a distinct clustering advantage. To create value in office real estate as an owner, you need rental growth, which is driven by both job growth and barriers to supply. Our markets have built in obstacles to new development, including a dearth of available sites, difficulty in permitting, anti development local ordinances and cost and complexity in construction. My last point on business model is Boston Properties' fully integrated operating capability and quality of execution. In 2020, we were able to lease 3,700,000 square feet with a weighted average lease term of 8.6 years, which is around 60% of our recent annual leasing averages, while the leasing activity in our markets was approximately 40% of recent annual averages.
In all our core cities, we a leading participant providing advantages and accessing new investment opportunities, procurement and attracting and retaining talent. We are an industry leader in ESG performance as measured by GRESB, the EPA, USGBC, Energy Star, FitWell and others and were recently recognized as the leading office company and 2nd best property company in Newsweek's 2021 Most Responsible Companies ranking. My next points relate to valuation. Because of the pandemic and the variability in our parking, retail and hotel income streams, Boston Properties FFO dropped approximately 15% the last three quarters of 2020 versus pre pandemic levels, which is clearly disconnected from our stock price, which has dropped 37% over the same period. The gap is caused by expectations, specifically concerned about gateway markets addressed earlier and the impact of work from home on office demand.
I will reiterate that we think more remote work is here to stay after the pandemic, but concerns over the impact to office space demand are overblown. Business leaders want their employees back in the office to foster culture, collaboration, teamwork and mentoring and to provide more supervision. In a recent employee survey completed by Gensler, workers want to return to the office as well where they believe they are most productive and collaborative. But 52 percent want a hybrid model with more time to work from home for convenience and safety from COVID-nineteen, fears of which should dissipate over time. However, 90% of those employees surveyed want an assigned workstation when in the office.
And while only 21% of those surveyed at a private office layout, 47% wanted it. Though employees may be working remotely more in the future, it will be difficult for employers to translate lower census into space savings due to employees' desire for more privacy and a fixed workstation. There is also a disconnect between where the private real estate market is valuing Class A office assets and gateway markets and where the public market is valuing Boston Properties. At our current share price, the look through cap rate on our portfolio is 5.9%. High quality office assets comparable to much of Boston Properties portfolio are trading at sub-five percent cap rate.
Though office transaction volumes were down materially in the last three quarters of 2020 from the prior year, activity improved each quarter as investors returned to the market. Volumes were down 45% in the Q4 versus the Q4 in 2019, but were up 59% sequentially from the Q3. Office was no more out of favor than other asset classes after the pandemic as office transaction volume was 29% of total commercial real estate volume both in 2019 and the last three quarters of 2020. There continues to be a robust market for life science real estate as well as quality office buildings and technology driven markets with more limited leasing exposures. Just in Life Science, Life Science is a portfolio dominated by a leasehold interest in University Park in Cambridge sold for $3,400,000,000 around $1500 a square foot and a mid-four percent cap rate with roll up potential and a partial interest in Discovery Park in Cambridge was sold for $720,000,000 representing $11.90 a square foot and a 4.7 percent cap rate.
And in office, 410 10th Avenue in New York City sold for $950,000,000 which equated to $14.90 a square foot and a 4.5 percent cap rate and 510 Townsend and 505 Brannen Street in San Francisco sold for a combined $570,000,000 $12.80 a square foot and a 5% cap rate. Though both buildings are leased long term, one is being sublet in full by its user. And in the Seattle CBD, a leasehold interest in 2 and You sold for $700,000,000 $10.20 a square foot and a 4.7% cap rate and 1918 eighth Avenue sold for $625,000,000 $9.40 a square foot and also a 4.7% cap rate. There is material investment activity in like assets to Boston Properties. And with interest rates forecast to remain low and the economic recovery described earlier, we expect transaction activity to increase and cap rates potentially to tighten for well leased assets.
And lastly, Boston Properties has the balance sheet and access to capital to take advantage of opportunities that will present themselves as a result of the pandemic. We currently have $3,200,000,000 in liquidity. And after the redemption of our bonds and fully funding our current development pipeline, we'll have $1,500,000,000 of liquidity remaining. We have been more actively monetizing in service assets having completed $570,000,000 in gross sales in 2020, and we expect a similarly elevated level of activity this year. We have access in size at attractive terms to the unsecured debt market if needed and have been developing increasingly formalized relationships with large scale private equity partners to help us fund acquisitions.
We have a reasonable pipeline of potential new opportunities in our core markets and Seattle and continue to look for investments that require leasing and or redevelopment to take advantage of our operating skills and to create higher returns. As mentioned, we also intend to invest more aggressively into life science real estate and have 5,800,000 square feet of new development and redevelopment projects under our control located primarily in the life science hubs of Cambridge, Waltham and South San Francisco. So in conclusion, the COVID-nineteen pandemic continues to create a very challenging environment for many sectors of the U. S. Economy and commercial real estate, including office assets.
However, the end of the pandemic is approaching and we are confident Boston Properties will emerge with strength and momentum given our portfolio quality, income stability, growth potential, access to capital and highly engaged management team.
Doug, over to you.
Thanks, Owen. I thought about just sort of stopping right there and starting the questions, but I guess I'll make some remarks and give some time for Mike as well. Good morning, everybody. As we sit here in January of 2021, we are shifting from COVID, COVID, COVID as the obstacle to a pickup in activity to vaccine, vaccine, vaccine as a signal to rejuvenate tenant conversations about bringing staff back to the office and starting the leasing transaction processes. There is no question that the rapid increase in COVID cases over the last 6 weeks of 2020 and the beginning of 2021 suppressed leasing tours in discussions during that period of time.
But in the last 2 weeks, 2 large Boston companies have announced their expected return to work dates. We signed an LOI for a 70,000 square foot tenant that's going to need space in December of 2021. And just yesterday, Amazon announced in Boston that they're committing to another 630,000 square feet to be built office building and bringing 3,000 additional jobs to the Boston CBD. So while the first half of twenty twenty one is expected to be quiet, we are cautiously optimistic that we've been through the worst of the pandemic and that the latter part of 2021 will have a discernible pickup in leasing transaction volume, parking revenue and retail sales. The year end market leasing reports that are published by the commercial brokerage organizations held few surprises as you probably heard to many of the analyst calls.
Leasing volumes were way off their historical pace and with the significant sublet space added to the market, we saw negative absorption and increased availability everywhere. It's important to remember that there are 2 types of sublet space. 1st, space that comes from users that had changes in their employee headcount and are clearly no longer going to need all that space. And then there's the second group, tenants that are being opportunistic, listing their entire premises, by the way, at no cost to them with an expectation that they'll decide what to do if they get an acceptable actionable offer down the road. They may reoccupy, they may relocate and transact or they may find a way to sublet a portion of their space.
We just don't know. But based on all the conversations we have had with our technology, our life science, our professional service, our legal, our financial firms, as well as the leasing brokers that are responsible for these listings, a change in workplace strategy, AKA, we're going to work from home or we're going to go to a disaggregated workforce, that's not what's driving the bulk of the sublet activity. One thing is sure, not all the sublet space is actually available. You might find the following illustrative that. In Midtown Manhattan, after the Great Recession, according to CBRE, from 2,008 to 2,009, about 24,000,000 square feet of space was put on the sublet market.
Between 2,009 2010, 13,600,000 or 57% of that was withdrawn from the market. Not all space is available. The Boston Properties office portfolio ended the year at 90.1% occupied. The quarterly sequential drop is entirely due to the addition of Dock 72 at 33% leased into the in service portfolio. As Owen said, we have 6 100 +1000 square feet of signed leases, 134 basis points in our in service portfolio that has not yet commenced revenue and hence is still defined as vacant, but it has been leased.
We completed another 1,200,000 square feet of leasing during the quarter. On a relative basis, my view of the ranking activity on our portfolio, active lease negotiations, tours, RFPs in our markets is as follows. Starting with the best and moving to the least. Boston, Waltham, by the way, we don't have any available space in Cambridge, Northern Virginia, Midtown Manhattan, Princeton, Los Angeles, the Peninsula Silicon Valley, DC and finally the CBD of San Francisco. During the Q4, in the Boston CBD, we did 5 leases including another full floor new tenant at Atlantic Wharf.
The cash starting rent on this full floor lease will be 34% higher than the expiring rent and there are future rent increases. The cash rents on the other four leases had a weighted average increase of about 30%. We continue to have additional activity in our CBD Boston portfolio, albeit with a number of smaller tenants under 10,000 square feet. A few are looking for incremental growth and a few were considering letting their 20 21 leases expire and are now actively engaged in short term renewal conversations. I also want to note that we finally obtained possession of the 120,000 square foot, 2 storey former Lord and Taylor building on Boylston Street during the early part of this month.
This was a big win as we believe we can find a far more productive use for this box that has been under lease since the mid-1960s to Lord and Taylor. In our suburban Boston portfolio, we completed 226,000 square feet of new leasing, including all of the remaining space at 20 City Point First Generation. This is in addition to the life science lease we did at 200 West Street. The cash rent on the 2nd generation leases about 150,000 square feet was up an average of 23% on a cash basis. We continue to have additional activity in suburban Boston.
In Waltham, we're negotiating a 60,000 square foot lease extension, a lease with a new tenant for a 63,000 square foot block of space and we're responding to a number of large life science lab requirements. At the moment, we don't have any ready to go vacant lab space, but we hope to begin our conversion of 880 Winter Street, 220,000 Square Feet during the Q2. And our 300,000 Square Foot 180 City Pointe Lab Building has been fully designed, fully permitted and we are simply waiting final construction bids over the next few months. Turning to Northern Virginia. This quarter, we completed 6 renewals at our VA 95 single story park, totaling about 218,000 square feet.
In addition to the VW commitment in Reston Next, we completed another 82,000 Square Feet in the Town Center in Reston. In total, in 2020, we completed 1,150,000 square feet of leasing in Reston Town Center. We still have more work to do. We have a good start to 2021 with lease negotiations ongoing for an additional 60,000 square foot block of space. In Reston Town Center, rents are basically flat to slightly down 1% to 2% on the relet since the expiring cash rents have been increasing contractually by 2.5% to 3% for the last 10 years and they will continue to do so on a going forward basis.
Our DC, CBD exposure rests in our JV assets, but here too activity in our portfolio has picked up. Completed 24,000 square feet of leasing during the quarter and we're negotiating over 120,000 square feet of leases as we speak. In New York City, we executed our lease with Asena at Times Square Tower for about 132,000 square feet of office space. We completed 2 floor deals in the New York City market, each 31,000 square feet at 601 LEX. 1 was a 1 year extension and the second was a 10 year renewal and the cash rent decreased about 8% on that renewal.
We also did 4 small transactions at 250 West 55th Street in Times Square Tower, totaling 26,000 square feet. 3 were short term and 1 was a 10 year deal. We're negotiating a full floor for transaction at 399 Park on a space that is not expiring until the end of 2021. While we didn't do much leasing in Princeton during the quarter, we have a number of active discussions ongoing and that we believe tenants will be making decisions to expand or relocate in late 2021 and are strongly considering Carnegie Center. When we talk about California, you need to appreciate the fact that the state has been strongly discouraging tenants from asking their employees to go to their offices for the last 11 months.
The uncertainty level and the lack of pedestrian activity at the street plane, particularly in the CBD of San Francisco has been more severe than anywhere else in our portfolio. And this has affected tenants' appetite for making any decisions. Just to put this year in perspective, from 2017 to 2019, there were on average 14 tech company leases per year in excess of 100,000 square feet. In 2020, there were none. Our San Francisco assets are 95% leased and we have 280,000 square feet expiring in 2021.
The Q3 produced just 3 transactions totaling about 23,000 square feet at EC. And during the Q4, we did another 4 leases, all renewals, up about 18% on a cash basis, totaling 20,000 square feet. It's pretty slow there. In South San Francisco, our Gateway JV is planning 230,000 square feet ground up lab development to begin over the next few months, followed by the conversion of 651 Gateway, which will be a renovated building if we're able to relocate the existing tenant there. There's more activity in the Silicon Valley Mountain View area than the rest of the Bay Area.
2 technology companies did 100,000 square foot plus expansions during the quarter and there are 3 active requirements right now in the market in excess of 200,000 square feet. There continues to be a slow resurgence of medical device, alternative energy, automotive, the hardware side of technology that are all out looking for space. We are seeing a few of these organizations looking at our Mountain View single story product, which is plug and play ready. In Santa Clara, we're going to be taking our 218,000 square foot Petersen Way building out of service when the lease expires in the Q2 of 2021. This was a covered land play and contributed about $4,800,000 of revenue in 2020.
We have entitlements for a 630,000 square foot campus permitted and improved ready to go. In spite of the challenging COVID related conditions in California, in Santa Monica, we continue our renewal negotiations with our 2021 expirations. And as I said at the outset, we signed a 70,000 square foot LOI at Colorado Center from a new tenant. You may recall earlier this year, we actually did an expansion with another technology company at the Santa Monica Business Park. I purposely didn't make any comments about market rents during my remarks.
With very limited activity, any conjecture about where rents will settle out is pure opinion. What I can tell you is that there will be large differences between deals cut on sublet space and direct space. Sublet landlords will have less appetite for capital and more leeway with lowering face rents or giving free rent. There will be tenants, however, that simply don't want the risk of sublet space. Will that prime tenant actually pay their rent for the full term?
Is that a risk worth taking? Or the as is conditions and other issues associated with that may make them very uncomfortable with those risks. There will be a very wide gap between the bid and the ask on direct space at the outset until we have a meaningful amount of direct deal comparable transactions for the market to understand. Landlords with vacant space that are quoting tenants that want a new installation will use capital to entice users to their space, not necessarily face rents. And landlords working on renewals will be more aggressive with swing space can be made available or lower contractual rates if the installation that's there currently works for the user.
However, there will be a flight to quality and the better buildings as tenancy value in paying less of a premium to be in the best assets in these markets. Conditions are going to value are going to vary submarket by submarket. I'm going to stop there and yield the rest of our time to Mike.
Excellent. Thanks, Doug. Good morning. So I'm going to cover the details of our earnings for the Q4. I'll also explain our guidance for the Q1 that we provided and some insight into our expectations for the full year 2021.
We've reinstated quarterly FFO guidance, which we hope will be helpful and serve as an indicator of our increased confidence in the operating environment. Our office tenant collections remain strong and we believe the write offs are largely behind us. We also continue to execute on new and renewal office lease requirements as evidenced by the 1,200,000 square feet of leasing in the 4th quarter and the 3,700,000 square feet of leasing in 2020 overall, despite the pandemic related shutdowns. We're encouraged by the rollout of the vaccine and are confident we will see a return of workers to the office in mass, but there remains uncertainty with respect to timing. We anticipate our ancillary revenues such as parking and retail will continue to be weak until the population increases.
Once we have better visibility into the timing, we expect to restore full year guidance as well. Our 4th quarter results contained 2 charges that I would like to explain. The first is a $60,000,000 non cash impairment of our equity investment in Dock 72, our 670,000 square foot development we put into service in the Brooklyn Navy Yard. This investment is held in an unconsolidated joint venture where we own 50%. Because the investment is unconsolidated, GAAP requires a mark to current fair value.
Also, while the $0.35 per share charge is a deduction from net income, it is added back to arrive at FFO. So it has no impact on our reported FFO pursuant to NAREIT's definition. Dock 72 is only 33% leased, as Doug said, and while we had some promising leasing activity pre COVID, there's little activity today and the market conditions in Brooklyn have weakened. We have increased our projected cost to stabilize as well as modified and extended our anticipated lease up, and the combination of this has resulted in a lower current fair value for the property. The extension of timing to achieve stabilization has a meaningful impact on fair value.
We see Dock 72 as a unique situation and we do not anticipate any additional impairments in the portfolio. The rest of our development pipeline is very well leased at 88%. Our in service portfolio is over 90% leased and honestly most of the assets have significant embedded gains. The second charge is a $38,000,000 or $0.22 per share non cash charge to net income and FFO for the write off of all accrued rental income for tenants in the co working industry. While these tenants are paying rent today, we believe the ongoing length of the pandemic is stressing the sector's revenue and liquidity.
As such, we do not believe they meet the standard to maintain an accrued rent asset on our balance sheet. As we discussed in both our second and third quarter earnings calls, co working is the remaining tenant sector that we've been monitoring closely. It is possible we could face a few individual credit situations this year due to the impact of the pandemic across the portfolio, but we don't anticipate additional significant accrued rent write offs to other sectors of tenants like we've experienced with retail and with co working in 2020. For the Q4, our reported FFO was $1.37 per share. If you exclude the accrued rent charge, our 4th quarter FFO would have been $1.59 per share and in line with consensus and the expectations that we shared with you last quarter.
Now I'd like to look forward to 2021. We have provided Q1 2021 guidance for FFO of $1.53 to $1.57 per share. At the midpoint, this is $0.04 per share lower than our Q4 2020 FFO before charges. The decline is entirely due to approximately $0.10 per share of seasonally higher anticipated G and A. The Q1 is always our highest quarter for G and A due to accounting for compensation.
If you look back historically, we typically record 30% of our annual G and A expense in the Q1. The increase in G and A expense is anticipated to be partially offset by higher revenue contribution from our portfolio, including the commencement of revenue for a portion of the signed leases that Doug described. We also expect lower interest expenses. We are redeeming our $850,000,000 bond issuance in mid February with cash on hand. These bonds have a yield of 4.3% and there will be no prepayment charge.
We're currently earning close to 0 on our cash, So we will see the full benefit of lower interest expense for the second half of this quarter and for the rest of 2021. So as we think about the full year 2021, there's a few things to consider. If you simply annualize the midpoint of our Q1 guidance, you get to about $6.20 per share, but that does not account for the seasonality of our G and A, the reduction of interest expense from our bond redemption or the incremental impact of leased developments coming online during the year. For modeling purposes, we suggest you consider adding the following to the Q1 annualized FFO of $6.20 per share. $0.19 per share for the impact of lower G and A for the rest of the year, dollars 0.08 per share from lower interest expense due to the bond redemption and $0.05 per share of incremental FFO from new developments coming online, including 159 East 53rd Street, which is 96% leased to NYU and where we expect to commence revenue in the second quarter 100 Causeway Street in Boston, which is 94% leased with projected revenue phasing in starting in the 3rd quarter and 200 West Street, our life science development in Waltham, which is 100% leased and is projected to deliver in December.
So adjusting our Q1 annualized run rate for these known items gets to approximately $6.52 per share for 2021. That said, we are not providing full year guidance for FFO because there remains uncertainty in our variable income streams, including income and our same property leasing, both of which impact revenues and occupancy. The timing of recovery from the pandemic is still unknown. It could have a material impact on the recovery of revenues from our parking, retail and hotel. Currently, these income streams are depressed.
Their contribution is nearly $30,000,000 lower on a quarterly basis than what we saw pre pandemic. We are hopeful that a portion of this revenue will start to return in the back half of twenty twenty one, but the timing is really reliant on the success of the COVID vaccines and return to a safe and healthy environment in our cities. We also have lease expirations in 2021 that will impact our occupancy and same property NOI. Our rollover for 2021 is 3,200,000 square feet. As Doug described, we already have 610,000 square feet of leases signed that will take occupancy of currently vacant space this year.
We're also actively working on over 1,000,000 square feet of new leases and renewals across the portfolio. Overall, we expect our year end 2021 occupancy to be flat to down 100 basis points compared to current occupancy. It's also worth noting that we have a meaningful amount of free rent that burned off in 2020 that will boost our cash same property performance and AFFO in 2021. Specifically, at 399 Park Avenue, we had 450,000 square feet of space in build out and under free rent for 9 months in 2020 that is now in cash rent. And at the General Motors building, 160,000 square feet of office space and a portion of our retail was under free rent for most of 2020 and are now paying cash rent.
This showed up in our results in the 4th quarter with a $10,000,000 increase in same property cash NOI sequentially from Q3 to Q4. In summary, we're excited about the prospects for revenue and FFO growth. Our portfolio cash flow is expected to grow in 2021. The success of the vaccine program should give rise to the recovery of our ancillary revenue streams and we have $2,200,000,000 of leased developments coming online over the next couple of years, all of which should drive future earnings growth and value. That completes our formal remarks.
If you could open the lines up for questions, operator, that would be great.
Your first question comes from the line of Nick Yulico with Scotiabank.
Okay, great. Thanks. Good morning, everyone. So I guess in terms of some of the pieces that you gave on 2021, it's helpful to think about. I guess, maybe starting first on the point about occupancy being year end flat to down 100 basis points.
Can you just maybe explain what that assumes in terms of embedded occupancy gain of, I think, 130 basis points, just trying to kind of square away how we should think about how you then get to a flat or down 100 basis point number by the end of the year?
So Nick, this is Doug. It's not as precise as you're going to want to hear, But our method of sort of coming up with that number is to understand the amount of space that we have rolling over. And while we have a probability on renewals, the real variability is on how much of the vacant space that we currently have, is going to A, be leased and B, be revenue producing because it has to be revenue producing, meaning we have to have delivered it in as ready space or in 2nd generation and not demolished. And so it's that's what's really driving the number to sort of flat to negative because we just don't know what we're going to be asked to do relative to the delivery conditions of that space and when revenue is going to start. And as I again, we sit here today with 134 basis points of lease space that's not revenue recognizing right now.
And we just don't know where we're going to be as we get to the end of the year. And honestly, we expect our transaction volumes going to pick up as the year goes on. It's going to be slow in the first half of the year. And our expectation is if the vaccine rollout goes as we believe it will, that there will be a significant pickup at activity once people are back in school from a population perspective and people are back in their desks and people are feeling very confident about their business prospects. And so the 3rd and 4th quarters are going to be back weighted, which again impacts that revenue number.
Okay. That's helpful. Thanks, Doug. I guess just one other question, kind of twofold on 2021 and one, the decision not to provide guidance, maybe just hearing a little bit more about for the full year, why you thought it made sense to not provide guidance since you did, I think, give a lot of components that help us think about a potential range. And then I guess in terms of when you're talking about the 652 base, Mike, and then you talked about some uncertainty on variable income streams and same property leasing.
I guess since you did give a year end sort of occupancy range, I guess I'm trying to think about the same property leasing and whether that ends up being a negative adjustment to that base on FFO that you talked about based on your year end occupancy number?
So I'll try to describe it a little bit more. And look, we're trying to provide as much I would say. On the same store, every 50 basis points of occupancy based upon our current kind of rental rates is about $15,000,000 So that's $0.09 a share is every 50 basis points of occupancy. The variable income streams that I talked about could add $30,000,000 a quarter. So we just don't know when that's going to come in.
I think that the hotel portion of that, which is minor, is only $5,000,000 a quarter. That we think is going to take longer, But the parking and the retail components of that, it could snap back more quickly. It could be Q3, it could be Q4. And it's just really hard for us to say when that's going to happen. So providing a meaningful guidance range to you all is just difficult at this time.
So we've chosen not to do that. But I think I've given you a sense just on these comments of what our expectation is. If our occupancy is going to go down, then after you pull out the charges we incurred in 2020 from the same store and you just think about run rate, if our occupancy goes down by 50 basis points on average, I would expect our same store to be down slightly. We look at these our lease up on a lease by lease basis. So we've looked at all of our units.
Our renewal retention has gone up and you've seen it quarter over quarter during the pandemic. It was, I think, 57% this quarter, which is pretty good. So we've done that analysis to come up with kind of the occupancy views that we have based upon the activity that we're seeing today in the portfolio. Hopefully, that's helpful.
Just to say it slightly different way,
Let me say it slightly different way. We're really good at understanding what's going to happen in the portfolio in the next 90 days with regards to the variable income. We're really not good at knowing what's going to happen 3 6 months from now. We hope that when we get to our next conversation with you, which is in early May or late April, we're going to be in a better position to know how things are going across the country from a variable perspective, but we may not know. But I think we're just we don't have the certainty associated with it.
And we just don't feel we can pontificate about the recovery of the base economy in terms of how people are going to act. And so that's why we're sort of sticking with this quarter by quarter methodology right now.
Okay, great. Appreciate the added details guys.
Your next question comes from the line of Derek Johnston with Deutsche Bank.
Hi, everybody. Thank A big bright spot in leasing with demand being pretty firm for life science and biotech companies was certainly welcome. But it seems that C suite decision making in fire and maybe to a lesser extent Tammy Tenens is a bit more hesitant or muted with commentary often including more work from home flexibility longer term. And obviously, people talk about the need potentially for less office space. What are you guys seeing in the field?
And when do you anticipate fire and TAMI tenants to reengage in a meaningful way? Will it be during 2021 or potentially pushed out of it?
Owen, you want to be on the soapbox first? Sure.
There are a few things there to unpack. Look, I think that you're correct. The life science demand is strong. Some of the other sectors are not. I think the reason for that is most importantly, we're in a recession.
And in all recessions leasing activity slows down. Businesses have more uncertain outcomes and CEOs are less likely to make major financial commitments, which are leases. So this is no different from prior recessions. I think office lags a bit. So I think you're going to we're probably not going to get more stronger leasing activity until later in the year when the virus dissipates, people come back to the office and the economy is clearly in improvement.
As I said in my remarks, we acknowledge the impact of work from home and do believe that workers in America and around the world will want to work from home on a part time basis more frequently. So we acknowledge that impact, but we also see with our and we also see with CEOs, I think the importance that they see in in person work and their strong interest in getting their employees back to the office. So then the issue is, okay, what's the impact of the additional part time work on office demand? And again, to save space by having with people working at home on a part time basis, you really need to do 2 things. You need to schedule when that time out of the office is because everybody can't be out of the office on Monday or Friday.
And 2, you have to go to flexible workstations and move people around. And again, if you're looking at employee preferences, one of them is they want to work from home more. And as I said in my remarks, 90%
of the people in the
survey in the Gensler survey said they wanted to fix workstation. So which employee preference will be accommodated? So again, we acknowledge there's an impact from work from home, but we think it's overblown for those.
Got it. No, thank you. Appreciate the color. Let's just stick on that employee survey that you guys mentioned in the remarks. I mean, I'd say to play devil's advocate, just because a worker wants an office or a dedicated workspace does not mean that they will be granted that, especially if they prefer or demand a hybrid model.
So hot desking seems to us a potential solution, especially in an AB or week on, week off model that allows deep cleaning over the weekend. So I guess like what data from business leader conversations lead you to believe that hot desking is ultimately unlikely? Thank you, guys.
Yes. Look, I think you have to say I mean, look, we all as employers want to accommodate our talented workforces. And that survey expressed employee preference. So I think business leaders across the country are going to have to sort out which employee preferences they want to try to accommodate. I talked about the fixed workstation.
Working from home more is also an employee preference. I do think strongly in talking with other business leaders, there's a strong interest in having employees return to the office because of all of the diminution that's going on in terms of culture, competitiveness, creativity, onboarding employees. So again, I think this is a question that business leaders are going to have to sort out which employee preferences are they going to try to accommodate.
Your next question comes from the line of Anthony Paolone with JPMorgan.
Yes. Thank you. Doug, you mentioned it's hard to know where rents are going to ultimately shake out, but you did do auto leasing in the quarter and sounds like you've got a pipeline. What where would you peg kind of the conversations around all in economics now versus pre COVID?
I think there it depends, Anthony, it depends on the market. And I mean, I will tell you that we're getting higher rents in our life science oriented in our suburban portfolio in Boston right now than we were pre COVID. And in a market like San Francisco, all we've done is renewals and all those renewals have been well in excess of what the current tenants are paying. And it's unclear if rents have really dropped by much. But I can tell you that in my heart of hearts, I do believe that we're going to see some softness in the markets that we're in.
So again, I wish I could give you a firm answer, but I just can't. Now if you ask 100 people right now based upon the activity that's occurred in these cities, our rents up or down by more or less than 10%. I would say that they would tell you that rents are down by less than 10%. But again, it's a net effective calculation, not a base rate versus a base rate previously.
I mean, given the rollover in 2021, I think you have a decent amount of Boston. Is it just do you anticipate that you likely have positive spreads across the portfolio this year when it's all said and done?
The answer is I think the answer will be yes. I mean, that's why I gave all that data on all the leases that we've done recently. Again, that's about what the rent was versus what the rent will be on a contractual basis, not about would the rent have been higher had we done the deal 6 months ago. So I mean that's an affirmative yes.
Okay. And then just a question on the capital allocation side. Just curious, how do you think about or how do you weigh kind of the JV route as an acquisition vehicle versus the complexity it adds to the company overall versus, say, just selling assets to raise capital? And then in terms of target markets, is Seattle the only target that you're not in or are there any others out there?
So I'll touch on that. We do have significant capital, but we also have significant ambition in terms of growing the company and making new investments that make sense for shareholders. So we do think it makes sense to extend the equity capital we have with partners. We have a rich tradition of doing this in the company. We have a reasonably significant portfolio that's already partnered with global leading real estate investors like Norges and CPP.
And we think extending that type of business makes a lot of sense. Selling assets is not an efficient way for us to raise capital. Most, if not all of our major assets have a significant tax gain, which requires a cash or it requires a special dividend. And therefore, the retention of capital is much lower. So for all those reasons, we think the joint ventures make sense.
And the other thing I would say on the JVs is, we are providing property services to those joint ventures. So we do enhance our yields as a result of providing those services to the joint venture partners.
Thanks. And then the Seattle piece of it?
Oh, sorry. Yes, I would say in terms of new markets where we currently are not in operation, Seattle is the only market that we are actively looking at investments right now.
Okay. Thank you.
Your next question comes from the line of Manny Korchman with Citi.
Hey, good morning, everyone. Mike, in terms of the co working exposure, can you just remind everyone where you're concentrated geographically from a co working perspective? And is it the lockdowns in those markets that are causing you to sort of take this take down those accruals and sort of pause in that income stream?
So this is Doug Mady. Let me try and answer that question. So we've basically been approached by every operator in our portfolio regardless of the market about relief. And we saw Regis this last quarter all over the country, put units into bankruptcy. So we're now 11 months into this pandemic and it's pretty clear that the flexible space operators customers, obviously many of which had short term leases and then many of those leases are probably expired.
They've been very slow to come back to work, but really not dissimilar from the census we've seen and our census as we said before is somewhere in the high single digits to the low double digits, right. So, this industry is simply just facing revenue challenges and we decided that given the credit deterioration, we should be recognizing rent on a cash basis. So that was the reason we did what we did when we did it. And with regard to our own portfolio, we have, I think, 13 units across the country, 3 in California, the rest in other portfolio in Washington DC and in Boston, nothing in New York, we have one in New Jersey. And in total, it's about $50,000,000 and we've actually reduced our exposure by about 100,000 square feet over the last year with 2 leases that have expired.
So, we don't have any specific concerns about any particular unit. We're current on everything right now, but we just looked at the world and said, these guys are going to have a really rough time. And we think based upon the credit situation, this is the time to do what we did.
Thanks for that. And then as you go into discussions with some of the longer term new leases, have you seen them either thinking about or actually changing their physical plan, more space, less space, that hoteling concept. We've discussed on this call as sort of just more topical trends, but as they build out their space with 10 year or 15 year leases, how are they building that out today?
So we have had this conversation in past calls and I would wish I could tell you that there's been a sudden change in the sort of view that the tenants and their architects are taken. But I can tell you that very few tenants are really looking at transformational design changes in their spaces across all industry types. Now that doesn't mean anecdotally that you won't find a customer that says, you know what, we are going to try and do this work from home workforce strategy, but we want all of our people to be able to come to the office and therefore we're going to need different types of room meeting rooms and different types of breakout areas and far less individual spaces. There are people talking about that, but it's the exception, not the rule to date. And for the most part, in all of the build outs we are seeing in our portfolio right now, it's business as usual pre pandemic.
And again, the tenants that are in place with longer term leases have yet to do anything with their spaces relative to making a change in the way it's currently configured because they have a unique way of looking at how they're going to sort of come out of the pandemic relative to their utilization of space. I'm a little surprised, but that's just that's the fact. We just haven't seen it.
Thanks, Doug.
Your next question comes from the line of Jamie Feldman with Bank of America.
Thanks. I was hoping to dig into some of the markets in a little more detail. I guess just starting out on D. Post election and the Democrat, Democrats doing well and the budget we've seen, any thoughts on what might change in either CBD or Northern Virginia?
So Ray and Peter, you want to take that one?
Yes, I'll start. Go ahead, Peter. Go ahead and talk.
I was just going to say, having not been here as long as Ray, but since the late '80s, typically when there is a line, houses in Congress and the administration, and certainly I think we are seeing it now with the talk of stimulus. It always positively impacts the real estate market. How that's going to occur and where that money gets spent, I certainly think the life sciences are going to benefit, which would indicate the $270,000,000 quarter and around NIH closer in, but also downtown. And there's talk about reenergizing the FBI. So historically, it's been a positive.
It's just given where we are with the pandemic, so probably a little more difficult to predict right now.
I will just add to that and this is more to Manny's point previously in yours, Jamie. But in D. C, relative to the 4 major tenants that we're constructing new headquarters for Volkswagen, Wilmer, Marriott and Fannie, we're seeing virtually no change to the pre pandemic space configurations that they were launching prior to the work from home motivation. And I think everybody, all 4 of those are extremely excited about getting their employees back to work. They're making virtually no plans for major downturns in the actual demand for space and they're quite excited about the new buildings we're building.
So in the suburbs, we just completed perhaps one of the most successful years in Northern Virginia we've had in 20 or 30 years. So if there is a pandemic impact to our suburban portfolio, we're sure as hell not seeing it.
Okay. And then what does the leasing pipeline look like for more Reston Town Center type product?
Well, specifically in Reston, we've got probably, gosh, another 200,000 square feet proposals out for occupancy this year. So and now we're running in rest of it, we're running up against the lack of available space. So, we still have got, gosh, about 150,000 square feet coming on where our new project RTC next. That is now coming to a point in a physical condition where we start showing the space. So we think that the real activity in D.
C. Will continue to be suburban focused with some hopefully Biden related activity downtown.
Okay. Thank you. And then I guess shifting gears to the Bay Area. I mean, we all see the headlines about corporate relocation activity. I'm just curious to hear, if you think about the next couple of years, how much of a drag you think that will really be have on market conditions?
Bob, you want to start with that one?
Yes. Corporations move from the Bay Area and this happens every time there's a recession. Oracle was not a big occupier of new space or someone that was taking space consistently over the last couple of years. So I think it has very little impact. In the case of HP, they've been shedding space for the last 10 years.
So I think, again, it has very little impact.
So Jamie, my additional response would be that the profitability, the revenue picture, the aspirations of the technology companies that have significant footprints in the Greater San Francisco and Silicon Valley have probably been are stronger now than they ever have ever been. And as I said to you before in my sort of prepared remarks, it's been a really tough time in San Francisco in particular because of the shelter in place orders that moved to basically asking people not to go to work if they can't help it, but being able to go if they could. And we're just waiting to see what happens with regards to the aspirations of these technology companies relative to understanding that there's a heck of a lot of additional labor available because of the recession and certain things that happened earlier in the year that residential rents have come down. So affordability is very significantly changed. And that San Francisco is still going to be a great city and that there are opportunities to expand there.
And it very well may be that we're surprised on upside. We just don't know. And there's an incredible amount of beta associated with what will happen in San Francisco. And I think everyone right now is looking at the worst and assuming that's what the facts on the street are going to be and not looking at the opportunity side.
Okay. That's very helpful. Thanks for everyone's
thoughts. Your next question comes from the line of Steve Sakwa with Evercore ISI.
Thanks. I guess first, Owen, I just wanted to go back to the $800,000,000 in, I guess, projected development starts or potential development starts. I guess a lot of that's bright life science, but just have you changed kind of your pre leasing hurdles? Have you kind of changed your yield targets? And what are you expecting on those projects to the extent you do start them?
Yes. Steve, on the life science right now, given the heat in the market and the success that we had with 200 West Street and the dialogue that we're having with customers, we would be prepared to launch speculative development and redevelopment in our core life science clusters. Maybe some of these dialogues with customers will be signed before we start, but we have a lot of confidence in the market. The yield requirements have not come down, so we're still shooting for 7 percent. And we would be a lot more we will and are a lot more cautious with office.
So pure office development, we certainly wouldn't launch without a pre lease.
Okay. And then I guess you mentioned sales might be a similar level, sounds like maybe $500,000,000 $600,000,000 Do you have any sense for kind of markets or how are you thinking about yields? How do you think yields would stack up? And are these sort of single tenant high credit deals with long lease terms that have sort of been the flavor of the day in the market? Or are these more traditional multi tenant, say, average lease terms, which really have not cleared the market?
How do we think about those sales?
Yes. Well, we are already working on a couple and we are sorting out the remaining assets that we want to sell this year. As we've discussed in the past, we do have these gains that come from the asset sales, but we are keeping our dividend flat and we have more suppressed income. So those gains will be used to pay the regular dividend. And Steve, I think the assets we will select will be a mix.
There will be assets that we consider non core. As you know, we've been selling $200,000,000 to $400,000,000 of those per year even before the pandemic. And then there'll be other assets that we think will meet the market in terms of some of the comparables that I described earlier in the cap rates that are being achieved. So I think it will be a mix.
Okay. And then Mike, I guess, you sort of given up, I guess, a reasonable number for earnings in 'twenty It sounds like that doesn't per se contemplate the potential occupancy decline that you and Doug spoke about, but nor does it contemplate on the plus side, some of those tenants that are currently in place that are maybe on cash accounting, where you're not really collecting a lot of rent or maybe rent at all. So how do we sort of think about those 2 kind of going in opposite directions and influencing that $650,000,000 number?
I think that the occupancy impact I mentioned in 2021, if it's 50 basis points, it could be $0.09 And on the ancillary income side, I talked about $30,000,000 a quarter, which is significantly more than that. And if you think about it, basically $12,000,000 is parking, dollars 12,000,000 is retail, some of which is vacated, but some of which is just not paying us right now. And the $5,000,000 is hotel, which again might take a little bit further to get back. So depending on the timing of when that stuff comes back, it could clearly outstrip any kind of reduction we might have in occupancy from the same store. We do have I think what you're getting as we had some tenants that are on abatements right now.
They're actually in occupancy. So we had $19,000,000 this quarter of those tenants. So we think that those tenants who are in occupancy and open will start paying rent again. Some of those were recognizing GAAP rent right now, some of them were not. It's probably about fifty-fifty on that.
So those tenants are in place in an occupancy and we're hoping to get back to more of a contract rent basis next year as part of that overall $30,000,000 increase.
Right. So not to put words in your mouth, but it sounds like those things have the potential to maybe outstrip or outweigh the potential occupancy decline that some of those really start to move in a positive direction?
Yes, they certainly do and especially when you get into 'twenty 2, when things are expected to even normalize further because there you're going to have both starting to get more towards a full run rate on some of this stuff that returns hopefully. And you're going to have more development coming online as well because in 2022, we're delivering Fannie Mae, we're delivering Google, we've got a lot of deliveries going on. And the development growth for 2021 that I described is really pretty modest. I think it's only $0.05 That's because that stuff is kind of coming in later in the year and we'll have a full year of that stuff in 2022. So I think there's a lot again, there's a lot of positive things that we've got going on.
Great. Thanks. That's it for me.
Your next question comes from the line of Vikram Malhotra with Morgan Stanley.
Thanks. Good morning. Thanks for taking the questions. So maybe just so two questions. First, just on the sublease market.
Interesting you mentioned at least some tenants are sort of testing out the market and putting everything on the sublease market. Just hope and see what sticks. But I'm just curious from your perspective, why is that occurring this cycle and why is that versus sort of prior cycles where we may not have seen that phenomenon?
We have seen in other cycles and other and which is sort of was my point with regards to New York City between 2,008, 2009, right? I mean, there was 24,000,000 feet that was put on and 13,700,000 that was taken off. It was exactly the same thing. There is nothing different about this cycle relative to sublet space than the last cycle, Other than the fact that for the last 11 months, there's been no traction from an absorption perspective because most people have not been transacting, particularly with the kind of spaces that are on the sublet market, which are a lot of times short term and are as is in many cases because they don't know when they're going to need the space because they're not sure when their politicians are going to give them the okay to have their public schools open and therefore where the employees can feel comfortable making plans to go back to the space even if the buildings are open.
Okay, got it. So last cycle, there were also just corporates who just put their entire space on the sublease space just to kind of see what sticks. But then as you say, some of it just they took it back as the economy improved. That's interesting. Maybe just second, you referenced sort of the implied cap rate at a 5.9 percent for BXP and the private market in sub-five percent range.
I guess just if I look at pre pandemic in the last 5 years, for whatever reason, the equity market have always sort of traded versus NAV, the equity market is afforded, call
it, a 20% discount or so plus to NAV.
Exhibit value. Post you take or ways to exhibit value. Post pandemic, assuming this kind of disconnect persists, what are some of the other actions or strategies you could pursue to close this gap?
Vikram, I think the key is to grow the company. I think the market values growth more than NAV, and that's what we're focused on.
Fair enough. Thanks so much.
Your next question comes from the line of Alexander Goldfarb with Piper Sandler.
Good morning. Good morning up there or down there. So question, first, Owen, you mentioned back on Seattle that that's the only market that you guys are looking at. But clearly, you see a lot more growth in places like Austin or Miami. I mean, you got Blackstone looking at buying a building down in Miami.
So as worker preferences change and certainly Florida looks to become Wall Street of the South and Texas gets a lot more tech,
At what point do some
of those markets start to create the same dynamic, culture, knowledge base, etcetera, that would attract you guys to start looking at markets like in Austin or Miami, etcetera?
Yes.
So, Alex, so a couple of things I would say. 1, we acknowledge that there is corporate relocation activity going on to South most recently to South Florida and to Austin. So I would say a couple of things. 1, I think you got to dig into that a little bit more. I mean, I'm not sure I would describe South Florida as Wall Street South.
I think if you actually looked at the size of the requirements that some of these larger financial institutions have in the Miami market, they're not that big. So it makes a big headline, but it's not a lot of space and it's not a lot of employees. So that's 1. And then 2, look, I do I think we all acknowledge Austin is a computer science cluster. There's no doubt about it.
But the and this is true in South Florida as well. The market dynamics for office investment are very different. The level of new construction and existing vacancy, even with Class A space, is very high and it's much more elevated than the markets that we operate in. So yes, you've got the growth, but you've also got plenty of supply coming on, and that has an impact on outcomes as a real estate investor.
Okay. And then the second question is on the dividend. Mike, if we use your implied FFO range and then deduct for all the fun stuff to get it to AFFO, it would suggest that the dividend is going to be meaningfully uncovered this year. Owen, I think you'd probably agree that no one buys BXP necessarily for the dividend. They buy it for the overall growth, especially given the low dividend yield relative to other companies.
So at what point does a dividend reduction become something the Board would contemplate, especially as you guys talk about all the development potential life science where the value creation in your platform is pretty good? At what point does the dividend come under reconsideration?
Our goal is to have a stable and growing dividend. We and given all the growth that Doug, Mike and I described on this call, we're going to grow back into our existing dividend in our opinion.
I mean, Alex, just step back. I mean, Mike said it, I thought pretty well, which is there's $30,000,000 of quarterly revenue that is not in our numbers right now that we absolutely is coming back. Whether it comes back in the Q4 of 2021 or the Q3 of 2022, we don't know. But it's absolutely coming back. And we have additional development that's coming online that's going to bring significant amounts of income.
We have real confidence in the growth in our taxable income and our FFO and our AFFO over the next 3 to 5 years, including 2022. And again, we hope in late 2021. So I mean, we're confident about what we have going on and our ability to increase our revenues in a significant way.
Just the other thing I would add to the question is, our FAD ratio is it's 105%. I wouldn't consider that meaningfully uncovered. And we anticipate that our cash flows and our AFFO are going to improve next year and that's without necessarily the improvement of the ancillary income, which would improve it even further. I mentioned the sequential quarter improvement in the cash flow on the same store and there's a lot of free rent that burned off in 2020 that is going to be there in 2021. So I agree with my colleagues that we're not thinking about resizing our dividend at this time.
Okay. Okay. Thank you. Thank you, guys. Thanks.
Your next question comes from the line of Michael Lewis with Truist Securities.
Great. Thank you. It looks like your tenant retention for 2020 average is about 45%. You could correct me if I'm wrong, but my real question is about the tenants that are not renewing and where they're going. Are they finding sublease space or maybe some cutting or eliminating their physical footprint or some moving to other markets?
So I guess the question is, are there any trends you're picking up on that front on the tenants that are moving out that are clearly different from pre pandemic?
Michael, this is Doug. I don't think there's anything that we can point to that would be a trend that we would be either encouraged by or discouraged by. It's the natural move out of tenants based upon the age of their space, the way it was configured and what their future plans are. And so we're we don't expect to see much in the way of changes in the profile of the kind of tenants that will stay versus kind of tenants that will depart for whatever reason.
Okay, great. And how many tenants have notified you of a return date to the office? In other words, do you have a rough schedule of how repopulation of your portfolio is likely to trend in the second half? And where the physical occupancy might be at the end of this year?
So the answer is nobody has notified us as the landlord. What we know is that they are having conversations internally and talking about dates that are beginning in the end of Q2, early Q3 and going as far into the year as the Q4 depending upon the particular company in the particular location. But I would say that certainty around knowing that there will be a date and that date is sooner rather than later is the change that has occurred over the past couple of weeks. And I guarantee you that if the vaccine rollout is effective and working that you will see more and more companies having the confidence to tell their employees that they expect those kids to be back in their seats in their those schools and getting on the buses come the fall of 2021. And the colleges will be back in session in person and there will be athletic events and things like that.
And it's going to be a question of simply getting through the scar tissue damage that's occurred over the last 11 months in terms of how quickly they ask those people to come back.
Okay. And then I'll just squeeze in one more if I can. I just want to confirm, the active development portfolio is 88% pre leased. Are there any tenants in there that want to renegotiate anything or maybe wish they had done their plans a little different, maybe like sublease space that could come back or any unusual risk that you see in any of those projects?
Definitively no to all of those questions.
Your next question comes from the line of Tayo Okusanya with Mizuho Securities. Your next question comes from the line of Daniel Ismail with Green Street.
Great. Thank you. I'm just curious regarding co working, does this experience change your thinking on how leases with these tenants might be structured in the future, such as the revenue share agreements?
Yes, I think it absolutely does. I think it makes it clear that, we don't have a lot of appetite for doing these leases with other people on a going forward basis relative to what our current exposure is. And that when we do this stuff with space in the future, it will be strategic and we'll have explicit needs in specific buildings and we'll probably look to do more of it ourselves because therefore we're sharing the revenue with ourselves.
And then on life science, we've seen life science cap rates trade inside of Class A office cap rates across your market footprints. But I'm curious, in your underwriting, are you considering it as a permanent change in valuation? Or does this revert to a more historical range post COVID?
I think a lot of it's driven by the fact that life science rents in a lot of the markets where we operate have gone up a lot over the last few years. So when you look at an existing asset, there's a big roll up in it from where the building is rack rented to where the market is and that's creating lower cap rates. If that dynamic changes, I think the cap rates could go back up.
And there's a scarcity factor associated with it. There's not that much of it anywhere in any particular market in the country. And Owen likes to use the word, it's the hot dot. There's lots of institutional capital that's saying, we don't have any of this stuff. We need to get some.
And so supply and demand, right, there's relatively little in the way of supply. There's lots of capital that's looking for it. And so at the moment, there's a very, very strong bid for it.
Your next question comes from the line of John Kim with BMO Capital Markets.
I just had a couple of follow ups. The leases that you signed this quarter had an 8 year term. But what is your appetite to offer shorter term leases to build up occupancy?
So we are in the business of leasing space, John. And if a tenant wants a short term lease, we will, transact on a short term basis. If a tenant wants a long term lease, we'll transact on a long term basis. We are customer centric and we want to do what our customers want to do.
Yes. And don't forget that again, we've been we've had a lot of success, I think, as you're pointing out in doing long leases. If we do the short extensions that Doug is talking about, generally those don't have CapEx. So we're in essence extending the tenant work over a longer lease term, which is also attractive.
So do you view that as a short term solution given where we are in the economic cycle or could this be a longer term trend of shorter leases, lower CapEx?
I think that you have different kinds of customers with different kind of motivations. I mean, there are lots of customers who are going to say, we think there's been a correction in the market and this is an opportunistic time for us to do a very long term lease. Those customers are going to want to get as much capital out of the landlord world as they possibly can and extend for as long as they think it's appropriate. So that's 15 to 20 years in some cases. I think there is another group of tenants saying, we're unsure, we're not it's not clear to us how our business is going to perform relative to our current workforce strategy.
We just want to kick the can for 18 months or 2 years and then look at it again, we'll have more clarity and more confidence about our decision. And then we'll be able to make a more permanent capital decision. I think that's always gone on and I don't think things are going to change dramatically other than I think it's going to be a slow ramp up this year just due to again, the way I referred to it, the scar tissue associated with the length of the time people have not been back together in their offices. And it's just going to change their decision making framework.
Okay. And then Mike,
I just wanted to clarify with you. Do you see the 4th quarter as being the peak quarter in terms of what you've offered in rent deferrals and abatements? It sounds like you think some tenants are going to start paying rents again, but I'm wondering if you're going to be offering more rent relief as well during the year?
We certainly hope so. I mean, I will say that many of our restaurant tenants, we were kind of going through the summer, because that's when we kind of have an expectation that it will be the next period of time when maybe there will be improvement. So there is additional dollars that will occur over the next couple of quarters. Based on what we know today, it's not going to be $19,000,000 because there's about of the $19,000,000 of those tenants, I think there's about $10,000,000 left during 2021. And we are not I guess you can never say never whether tenants are going to come to you again.
But at this point, we've taken care of a lot of those tenants.
Great. Thanks.
Your next question comes from the line of Peter Abrahamowitz with Jefferies.
Thank you. I just want to go back to Owen's comments at the beginning. I think the words you used were the most significant and predictable improvement in conditions and leasing activity, which I think makes sense coming off the base we had in the second and third quarter. But at the same time, we're still coming out of a recession and a lot of office using jobs have been lost. So I'm just curious how your outlook where your outlook kind of contemplates for returning to job growth and how that impacts your thinking for 2021 2022?
Yes. No, look, I chose those words carefully. And I think that and maybe the interesting one was predictable. And I guess the difference of this cycle is it's been less it's not been driven by a cyclical move in the economy, it's been driven by a pandemic and a health crisis. And so with the vaccine progress, I think we see and I think the world sees a pretty obvious correction in this over the next 6 months.
Again, knock on wood, maybe something goes wrong with the vaccines or there's a slower rollout or there's something that goes on. But in essence, unlike an economic recovery, which perhaps is harder to predict, Again, if this is all about vaccinations, maybe this one is easier to predict. And I think as all of us come out of the isolation that we're getting really tired of and return to the world and to our offices and to restaurants and to theater and to each other, the economy is going to reopen and I think jobs are going to come back. I think of all the small businesses that will get to reopen and restart as part of all this. So we do think this year we're going to have a significant improvement in economic activity.
Look, office leasing tends to lag that. So it's not so we do think by the later quarters of this year that the office activity will also elevate as a result.
Right. Okay. Thank you.
Your next question comes from the line of Manny Korchman with Citi.
Hey, it's Michael Bilerman here with Manny. So I wanted to sort of talk on 2 topics. 1, just coming off the vaccine. Owen or Doug, are you thinking about, I guess, requirements, A, just Boston Properties employees in terms of vaccinations, any contractors, building staff, in terms of making your assets competitive for tenants to feel comfortable they're coming into a safe environment. And I know you can't force your tenants, but just how are you sort of thinking about vaccine rollout and how it adheres to your public places?
Devin, do you want
to hit that? Yes. So Michael, I will I'll give you an discussed response to that. So we have the view, I think that in our particular marketplaces, the vast majority of the people who are tenants in our buildings will get the vaccine. And it's hard to go from there to a rigorous requirement that people get the vaccine, But it's not something that we won't talk about understanding what the ramifications of that are.
But if the vaccine is effective and the vast majority of the people get it, the vaccine will have done its duty, which is to effectively eradicate the virus. And we won't have to really worry about the issue sort of on a going forward basis. But it's not something that we don't that we haven't not thought about. Okay.
And then Doug, you talked a little bit about the sublease space and giving the 2,009, 10 analogy for New York. The similarity is that we do have an economic crisis that's going on. But there's a big difference between the GFC and today where people are not in their offices, right? People are still going to their offices in the GFC and people are not today. You have a lot more discussions about movement of corporations around the U.
S. You certainly have a significant amount of discussions around about full remote working and hybrid remote working. And I think you know I love being in the office and I love the interactions that provides and the advancement in a lot of things. But what gives you the confidence that that sublease space won't have a more material impact because it doesn't feel like it's all opportunistic. It feels as though it is much more real today as people think about the amount of square footage that they need in this new environment?
I think you're asking a lot of fair questions and the answers are unknown at the moment. I guess our intuition is that as people start to go back to work, the fear of mix missing out and all of the opportunities that in person work have will become more clear to more people and they will start to get back on the bandwagon. Again, I am not saying that there won't be much more flexibility in the way employers treat their employees relative to requirements to be in a seat every single day of the week. But I guess I'm a strong believer in and Owen and I have talked to lots of people about the nature of the office from both a business and from a social capital perspective and how critical it is for the growth of businesses and the growth of the individuals that are in those businesses. And so I guess I am more optimistic optimistic than your questions are suggesting, about the value that people will ultimately and clearly see in having people going back to work in a very significant way.
Again, on the margin, is it going to be a headwind? Absolutely. But I don't think it's going to be the radical disruptor that is certainly baked into, I think the value of CBD office docs.
Right. And I'm not trying to be a complete pessimistic person. I'm just trying to balance sort of the comment about looking at 'eight, 'nine and 'ten and the sublease space coming back feels different than where we sit today. But I understand sort of the points that you're making. How do you think
Let me just give you 2 real life examples of sublet space, okay. So Mizuho, which moved into a new installation on Sixth Avenue was always planning on putting their space on the sublet market. Okay. I don't think that sublet space is going to be competitive any longer because of other space on the market. So is it available?
Yes.
Is it going to be a sublet space that's going to
be actionable? I don't know. I think if you ask the people from BlackRock, I don't know if they put some space on the sublet market, they had planned to put space on the sublet market because they took additional space when they were doing their lease and they always had the expectation that they would have some short term sublet space. So there's a lot of that stuff that's there this time as well that people are all looking at it saying, oh, it must be a change in philosophy for the workforce management of that organization and they're going to have more people working from home. I just don't think that there's as much of that as people think there is in the market we 1,000 square feet of new space in Boston.
We saw Facebook last quarter take the REI building in Seattle. I just see there are tenants on either side of the table doing contrary things at the same time. So again, I think it's very hard to make a directional conclusion.
What do you think the cadence is of the return to the office, right? And a corporation today, if they made the decision in March to say, hey, we're going to come back, I would assume there's a pretty long delay and amount of time that they have to give people, given the long people may have moved, they're in different places, maybe at that time when the workforce calls them back and they say, you know what, I like being here, I'm going to go get a different job or go somewhere else. How do you think that cadence in your markets in terms of corporations making decision and then ultimately when their workers really come back into the office?
Owen, you want to take that one?
Yes, sure. Look, I think the key our premise on this that we described a couple of times this morning is employers want their employees back in in person work. They believe their companies will be more successful with that going on. But I don't think they're going to push it until the environment is safe. And therefore, the infection rate needs to drop precipitously from where it is now.
And I think it will as more people get vaccinated and more people are immune because they've recovered from infection. So when I think it's deemed to be safe, I do think then companies are going to be faced with the dilemma, Michael, that you described, which is, okay, we want people back and how hard are we going to push it because our employee base, some of these employees do like to work from home and they want to be out of the office. I don't think they want to be out of the office full time, but they certainly want to be out of the office more. So these employers are going to have to decide what are we comfortable with, what do we what do we need to do to be competitive in our industry in terms of in person work and what kind of policies can should we put up to balance this competitiveness issue with the retention of talent. And I think each company is going to make those decisions differently.
But again, I think as the infection rate goes down and my assumption is that will be over the summer, I do think you'll see a lot more companies requiring employees to come back to work. And I think different companies will have different policies around work from home.
And I would say, Michael, that if an employee if a human being is vaccinated and that human being is going to a restaurant to eat, they have basically said, okay, the stigma of being in the population is now over. And so as more and more of you as we see more and more of those types of things occurring, it's going to be quite clear that the difficulties associated with asking your employees to come back to work are going to have dissipated because they're going to have demonstrated that they are comfortable being in and around other human beings in a very close proximate way. If you're a believer in the efficacy of the vaccine and the vaccine does what it really is designed to do, which is you don't get sick. If you're in contact with the virus, I think there's going to be a stronger desire for people to come back. Again, once we've solved those other issues, which are we've now put people in a position where their children are going back to school, where they're comfortable going on public transportation, where all of the things that have been impediments to, at least intellectually people coming to work and we have a governmental programmatic desire to get people back in seats, right.
As opposed to saying, we think that people should remain as far apart as possible because we're trying to keep this pandemic in containment, which is where we are and have been for the last 11 months.
Right. I was just trying to think through the timing of the corporate deciding, okay, it's now safe, we can do it. And then asking their employees, it's not like they can make the decision on Fridays and everyone's there on Monday. I would expect there's a pretty slow build to getting people back, given how long they've been out of the office. And I don't know what that ramification is on leasing, on fundamentals, all the other income sources.
So I'm just trying to as I assume corporations are thinking about all this at this point, given the vaccine distribution, given the efficacy, right, they're all trying to come up with their plans. And I just didn't know if you had more insights about if they flick the switch, all right, it's no longer opt in, it's opt out, how long that could last for as we move into that direction? So a couple of comments there that
Michael, I don't think anybody is going to surprise their employees. I mean, we're doing it ourselves. We try to give a lot of preview over how we see the world and when people should anticipate coming back to work. So I think that will help in this repopulation that you described.
Great. Thanks for all the time, guys.
You bet.
Your next question comes from the line of Tayo Okusanya with Mizuho Securities.
Yes, sorry about that earlier. Can you hear me?
Yes, we can hear you.
Perfect. Just a quick one. I know we're running long. Could you talk a little bit about just how you're thinking about dispositions in 2021 given some of what you've seen in regards to asset pricing, your uses of capital next year and as also your leverage target?
Yes. No, as I mentioned in my opening remarks, we sold $500,000,000 between $500,000,000 $600,000,000 of assets in 2020, and that's an elevated level for us at least over the last 5 or 6 years, and we anticipate that level, plus or minus going into 2021. We have a couple of assets we're working on now. As I described, capital market conditions for office are reasonably favorable, particularly for assets with certain characteristics. And I think you should count on us selling around that level this year.
And from a leverage perspective, Tayo, we haven't changed our views on the leverage that we think is appropriate to run the company at, that it's somewhere between the mid-6s and the mid-7s on a net debt to EBITDA basis. The leverage is obviously a little bit higher this year because of some of the income items that we've talked about. And then if you look at our supplemental, our leverage is reported at 8.07 this quarter, but that's because calculation annualizes the charges, that we took this quarter. So we have provided a footnote that describes that if you pull out the charges, the effective leverage is 7.26, which is within the range that we are comfortable operating in. And then got a lot of income coming in off of the development pipeline over the next couple of years that we've described and we've described in the past, where a significant amount of that money has already been spent for that development pipeline.
So that will naturally delever us over the next couple of years.
Got you. Thank you.
We have time for one final And that question comes from the line of Rick Skidmore with Goldman Sachs.
Mike, just a quick modeling question. How should we be thinking about real estate taxes as we go forward, given maybe what we've seen in 2020? And then sort of are you hearing anything from the cities with regards to how they're thinking about real estate taxes? Thanks.
Hi, Rick. This is Doug Linde. So obviously, it's market by market, right? In California, we know exactly what's going to happen because of the legislative, referendum that didn't pass. So that one's taken care of.
In New York City, I am sure that assessments are going to go way down. We won't know what's going to happen with the tax rate. But in New York, everything is sort of bled in over a 5 year period of time as those changes occur. So year to year, it's not a very big change AKA versus what it would have been where we not in this evaluation challenge. In a market like Boston, there's been so much addition to the supply that we actually don't expect to see much in the way of significant rises in real estate taxes because of the assessments have gone up, but there's more base.
The cities have actually reduced the tariff rate, so it hasn't been significant. And similarly, I think in the Greater DC area, we'll obviously see they have tri year valuations in the district and you don't see much difference unless your building is being revalued. But net net, I mean, it's quite clear that to the extent that a jurisdiction has some fiscal issues, it's going to be looking to its real estate taxpayers to bear a portion of that. But I don't think in the short term, it's going to be a meaningful detractor in our revenue or impact our margins in a very significant way.
And obviously, our tenants, we escalate our real estate taxes to our tenants. So an increase doesn't come back to us unless we are we have vacancy or we have leases rolling. So only a small portion of that increase actually comes to us every year.
Thank you.
And I would now like to turn the call back over to the speakers for any closing remarks.
Thank you, operator. Thank you, everyone, for your interest in Boston Properties. That concludes the call, all our comments and questions. Thank you very much.
This concludes today's Boston Properties conference call. Thank you again for attending and have a good day.
