Office Conversions Find New Life After Property Values Plunge
Office-to-residential conversions are gaining traction, helping revitalize depressed business districts
Office-to-residential conversions are gaining traction, helping revitalize depressed business districts
Developer efforts to convert emptying office towers into residential buildings have largely gone nowhere. That may be finally changing.
The prospect of transforming unused office space into much-needed housing seemed a logical way to resolve both issues. But few conversions moved forward because the cost of acquiring even an aging office building remained too high for the economics to pencil out.
Now that office vacancy has reached record levels, sellers are willing to take what they can. That has caused values to plunge for nothing-special buildings in second-rate locations, making the numbers on many of those properties now viable for conversions.
Seventy-three U.S. conversion projects have been completed this year, slightly up from 63 in 2023, according to real-estate services firm CBRE Group. But another 309 projects are planned or under way with about three-quarters of them office to residential. In all, about 38,000 units are in the works, CBRE said.
“The pipeline keeps replenishing itself,” said Julie Whelan , CBRE’s senior vice president of research.
In the first six months of this year, half of the $1.12 billion in Manhattan office-building purchases were by developers planning conversion projects, according to Ariel Property Advisors.
While New York, Chicago and Washington, D.C., are leading the way, conversions also are popping up in Cincinnati, Phoenix, Houston and Dallas. A venture of General Motors and Bedrock announced Monday a sweeping redevelopment of Detroit’s famed Renaissance Center that includes converting one of its office buildings into apartments and a hotel.
In Cleveland, 12% of its total office inventory is either undergoing conversions or is planned for conversion. Many projects there are clustered around the city’s 10-acre Public Square. The former transit hub went through a $50 million upgrade about 10 years ago, adding fountains, an amphitheater and green paths.
“You end up with so much space that you paid so little for, that you can create amenities that you would never build if you were doing new construction,” said Daniel Neidich, chief executive of Dune Real Estate Partners, a private-equity firm that has teamed up with developer TF Cornerstone to invest $1 billion on about 20 conversion projects throughout the U.S. in the next three years.

Conversions won’t solve the office crisis, or make much of a dent in the U.S. housing shortage . And many obsolete office buildings don’t work as conversion projects because their floors are too big or due to other design issues. The 71 million square feet of conversions that are planned or under way only account for 1.7% of U.S. office inventory, CBRE said.
But city planners believe that conversions will play an important part in revitalising depressed business districts, which have been hollowed out by weak return-to-office rates in many places.
And developers are starting to find ways around longstanding obstacles in larger buildings. A venture led by GFP Real Estate is installing two light wells in a Manhattan office-conversion project at 25 Water St. to ensure that all the apartments will get sufficient light and air.
Cities such as Chicago, Washington, D.C., and Calgary, Alberta, have started to roll out new subsidies, tax breaks and other incentives to boost conversions.
The projects are breathing new life into iconic properties that no longer work as office buildings. The Flatiron Building in New York will be redeveloped into condominiums. In Cincinnati, the owner of the Union Central Life Insurance Building is converting it into more than 280 units of housing with a rooftop pool, health club and commercial space.
In the first couple of years of the pandemic, office building owners were able to hold on to their properties because of government assistance and because tenants continued to pay rent under long-term leases.
As leases matured and demand remained anaemic, landlords began to capitulate and dump buildings at enormous discounts to peak values. In Washington, D.C., for example, Post Brothers last year paid about $66 million for 2100 M Street, which had sold for as much as $150 million in 2007.
Washington, D.C., has been particularly hard hit by the office downturn because the federal government has been especially permissive in allowing employees to work from home .
“We’re able to make it work as a conversion because it was no longer priced as though it could be repositioned as office,” said Matt Pestronk , Post’s president and co-founder.
Increasingly, more deals are taking place behind the scenes as converters reach deals with creditors to buy debt on troubled office buildings and then push out the owners. GFP Real Estate reduced costs of its $240 million conversion of 25 Water Street by buying the debt at a discount and cutting deals with tenants to exit the building before their leases matured.
One of the first projects planned by the venture of Dune and TF Cornerstone likely will be the Wanamaker Building in Philadelphia. TF Cornerstone just purchased the debt on the office space in the building and is in the process of taking title.
“The banks are foreclosing and doing short sales,” said Neidich, Dune’s CEO. “There’s a ton of it going on.”
In Washington, D.C., a conversion of the old Peace Corps headquarters building near Dupont Circle is 70% leased just four months after opening, said developer Gary Cohen . Rents are higher than expected.
“If that’s the way to get people downtown, that’s what we have to do,” Cohen said.
Not all developers agree that the economics of conversions work, even at today’s low prices. Miki Naftali , who has converted more than five New York properties over the years, said he has been very actively looking at conversion candidates but hasn’t yet found a deal that works financially.
One of the issues facing converters is that even if an office building is dying, it often has a few existing tenants who would need to be relocated. Some buildings would need atriums to ensure that all the apartments have sufficient light and air.
“When you start to add everything up, if your costs get close to new construction, that’s when you get to the point that it doesn’t make financial sense,” Naftali said.
Some landlords are including clauses in leases that give them the right to evict tenants to make room for a major conversion. Others are keeping a small ownership stake when they sell buildings so that they can learn the conversion process for future buildings.
“The world is looking at these assets in a different way,” said developer William Rudin , whose company decided to learn the conversion process by keeping a stake in 55 Broad Street, a downtown New York office building it sold last year to a converter.

AI-powered travel agents are challenging online booking platforms, but Airbnb’s exclusive listings and direct customer relationships could give it an edge. Its next challenge: turning repeat guests into loyal customers through stronger rewards and innovation.
AI agents like Muse can already find you the cheapest hotel room in Paris. But they can’t locate a cheaper version of that Catskills cabin you’ve been eyeing, because it might only be available on Airbnb ABNB -1.43%decrease.
Investors should pay attention to that distinction. When Meta Platforms META 3.38%increase launched its Muse agent last month, travel stocks including Booking Holdings BKNG -1.19%decrease, Expedia and Airbnb all fell sharply.
Airbnb, though, has a real chance to emerge as a winner from the upheaval. The catch: Its stock already reflects above-industry growth. To justify its valuation, Airbnb will need to turn repeat customers into loyal ones.
Online travel companies make much of their money by simplifying search and collecting fees on bookings. AI agents threaten that model.
But not all travel marketplaces are equally exposed. Booking and Expedia largely sell hotel rooms that travelers can also book directly or through competing sites. If an agent can find the same room elsewhere, it has little reason to favor either Booking or Expedia.
Booking and Expedia also sell sponsored listings that steer travelers toward particular properties. Wells Fargo estimates those will account for about 8% of Expedia’s revenue and a much higher percentage of profit next year.
Airbnb has more ways to adapt. More than half its listings are available only on its platform, and more than 90% of its traffic comes directly to its app or website.
The customer relationship doesn’t end after booking, either. Bernstein analyst Richard Clarke notes that 90% of Airbnb guests go on to message their hosts about arrival times, keys or local taxes, giving Airbnb a connection to both sides of the transaction.
How the companies have responded to the possible agentic future is telling.
Expedia quickly signed on as a Muse partner. Airbnb hasn’t, and Chief Executive Brian Chesky says AI chatbots have so far been a boon, sending customers to Airbnb’s website.
Chatbots might work for buying paper towels, he quipped at a Skift conference last month, but people enjoy planning trips. He argued that browsing dozens of homes isn’t something a text-based chatbot is well suited for.
Still, the AI jitters arrived just as Airbnb was persuading investors it deserved its pricey multiple. For years after its 2020 initial public offering, the stock—which trades around 25 to 30 times forward earnings—went nowhere. Investors saw a mature operator trading at a growth premium.
This year, Airbnb growth seems to be accelerating. The stock jumped in August after the company raised its full-year revenue-growth guidance with its second-quarter results. Wells Fargo analyst Ken Gawrelski credits a run of product improvements under a revamped leadership team.
Among the changes: letting guests reserve now and pay later, adding hotels, and a redesigned home page and app. Investors were also betting on what comes next, including thousands more hotels, car rentals and, eventually, advertising.
The irony is that some of those growth drivers push Airbnb closer to the kind of business Booking and Expedia run—the kind of business AI agents could threaten. Even if AI agents capture a large share of travel planning and booking, Airbnb would capture the demand. But it and others would slowly lose control over how customers find and choose properties.
That would undermine the advertising opportunity investors are counting on. The bigger point for Airbnb and other marketplaces is that losing control of customer acquisition could mean surrendering some of their pricing power and margins.
To bulletproof itself, Airbnb might look to another e-commerce giant that has so far kept AI agents at arm’s length: Amazon.
Like Amazon, Airbnb has a loyal customer base and hard-to-match supply. But it has nothing like Prime membership to make customers think twice before taking their business elsewhere.
That is where loyalty comes in. Business travelers stick with Hilton or Marriott because enough nights earn them perks. Leisure travelers rarely accumulate stays with one chain. Airbnb has millions of listings and plenty of repeat customers, but no broad rewards program. It has begun experimenting with credits on hotel stays, but it should make loyalty a priority, not just a promotion.
Airbnb also plans to launch its own AI agent next year. But travelers using an agent might still want it to search Airbnb, Vrbo, Booking and hotel websites alike, rather than limit itself to one company’s inventory.
Eventually, Airbnb might have to strike deals with agent makers, using its unique homes as leverage to negotiate favorable terms, says Gawrelski. Such deals, along with rewards for loyal guests, could over the long term eat into the company’s roughly 13% take rate, he adds. But if they bring in enough additional bookings, the trade-off could be worthwhile.
History offers a reason not to panic. The shift from desktop to mobile unsettled investors in Alphabet and Amazon, but both emerged as major beneficiaries. Companies with valuable assets can come out of a platform shift stronger, if they adapt quickly enough.
Airbnb has homes the bots can’t easily replace. Now it needs to give guests a reason to insist on booking them there.
