If you have looked at a new condo in the Seaport this year, you have probably heard the line. One Harbor Shore, the last tower going up on Fan Pier, is being sold as the final opportunity to own a piece of Boston’s premier waterfront. It is a good line. It is also doing a lot of work.
Here is what is actually true. The Fallon Company is finishing One Harbor Shore, 122 condos on the last open parcel at Fan Pier, with delivery expected later this year. Behind it, one small project is still under construction anywhere in the downtown core. That is 55 India Street, 29 units on the Greenway. After those two, brokers estimate it will be at least five years before another major condo tower could clear permitting and construction, if it happens at all. That part is not marketing. Boston really is about to run out of new luxury condos to sell.
The mistake I watch people make is what they do with that fact. Sellers hear “no new supply” and assume every condo in the city is about to reprice higher. Buyers hear it and panic that they have to buy now or miss the market. Both are reading a narrow story as a broad one. The scarcity is real, but it concentrates. It pools into specific, already-built waterfront and downtown buildings. It does not lift the entry-level market across Dorchester, East Boston, and Jamaica Plain, because that market never had a supply problem in the first place. It has an affordability problem, and no shortage of penthouses fixes that.
What is actually left to build
Walk the downtown core right now and count the condo cranes. You get to two.
One Harbor Shore is the big one. 122 residences, 14 stories, designed by CBT Architects, on the last waterfront parcel at Fan Pier. The Fallon Company broke ground in August 2024 with a $215 million construction loan from Bank OZK and is aiming to deliver later this year. The Boston Globe calls it the final piece of Fan Pier, the last building in a 21-acre master plan that took Fallon roughly sixteen years to complete. That is the honest version of the “last on the waterfront” claim, and the distinction matters. More on it below.
The other crane is at 55 India Street, a 12-story, 29-unit boutique building from Boston Residential Group on the last open development site on the Greenway. It locked down $90 million in financing in late 2024 and is due to finish this year. Five of its units are set aside as affordable artist lofts.
That is the entire active downtown condo pipeline. Two buildings, 151 new units between them. For a city that delivered a new luxury high-rise almost every year for a decade, that is close to nothing. And the buildings that were supposed to come next are not coming next. The 231-unit Motor Mart Garage redevelopment near the Common was put up for sale in January 2026 without ever breaking ground. Fortis Property Group’s approved 125-unit expansion at the Dock Square garage has not started either. These are permitted projects sitting idle. The pipeline did not slow down. It stopped.
Why the cranes stopped
The reason is not mysterious, and it is not local politics. New towers stopped penciling.
BXP put its approved 27-story Back Bay Station tower on hold indefinitely, and president Douglas Linde said the quiet part out loud. New development in Boston, he said, “doesn’t really pencil in relative to where existing rents are now.” He pegged construction cost at $1,400 to $1,600 a square foot and said he would need mortgage rates back near 3 percent and lender premiums cut roughly in half before it made sense to build. That was an office tower, but the math is identical for condos. Jonathan Miller of the appraisal firm Miller Samuel told Bisnow that developers cannot make the numbers work across the three costs that matter, land, construction, and labor, with the 30-year mortgage sitting around 6.5 percent this summer.
You can see the freeze upstream, too. The Boston Planning and Development Agency approved the least new development in a decade in 2025, about 5.8 million square feet, roughly half of what it greenlit in 2024. Residential permits across Greater Boston are down 44 percent from their 2021 level. The condos delivering in 2026 are the tail end of projects financed years ago, when money was cheap. Nothing is refilling the funnel behind them.
The slogan and the substance
I want to separate two claims, because the marketing blurs them on purpose.
The first claim is that One Harbor Shore is the last building at Fan Pier. That is literally true. It is the final structure in Fallon’s master plan, precise and verifiable.
The second claim is that it is the last chance to buy new on Boston’s waterfront for years. That one is a market read, not a hard fact, and it comes from brokers, not from a developer filing. It happens to be a good read. With nothing under construction behind One Harbor Shore and 55 India Street, and a five-year runway to permit and build anything new, the odds that a comparable waterfront tower opens before 2031 are genuinely low. But notice the difference. One is a fact about a parcel. The other is a forecast about a market. When a listing agent hands you the second one as if it were the first, that is your cue to slow down, not speed up.
Prices work the same way. The range you will see quoted for One Harbor Shore, roughly $1.3 million for a junior one-bedroom up to $5.8 million for a three-bedroom, is a broker estimate. As of this writing the developer has not published an official price sheet. So when you hear a number, the first question is whose number it is.
Where the scarcity actually shows up
Here is the part that matters if you already own. When the “wait for the next new building” option leaves the table, its value does not evaporate. It moves. It pools into the buildings that already exist and cannot be replicated.
Think about what a buyer who wanted brand-new, full-service, doorman-and-amenities living downtown could choose from over the last decade. Millennium Tower in Downtown Crossing. Pier 4 and Echelon in the Seaport. St. Regis on the waterfront. One Dalton in Back Bay. Winthrop Center and Raffles more recently. Every year brought a new one, so no single building could hold a scarcity premium. The next tower was always eighteen months away.
Take that option away and the calculus flips. A resale unit at Millennium Tower or the St. Regis is no longer competing against a building that does not exist yet. For the specific buyer who wants that product, new construction, waterfront or skyline views, a full amenity package, the supply is now fixed at the buildings standing today. That is where pricing power concentrates. Not across the condo market. In maybe a dozen addresses in the Seaport, Back Bay, Downtown Crossing, and Fort Point.
This is a forward story, not a green light to overprice
If you own in one of those buildings, do not read this as permission to tack 15 percent onto your asking price tomorrow. The scarcity is real, but it arrives on a delay, because there is still new inventory to clear first.
Look at absorption. At South Station Tower, the Ritz-Carlton Residences, fewer than a quarter of the 166 units had sold as of this spring. Winthrop Center, 317 units, was about 42 percent sold since it opened in 2022. The St. Regis was further along at roughly 60 percent. And One Harbor Shore is about to add 122 more brand-new units to that pile. The market has to digest the last wave of new luxury before “no new supply” actually starts tightening resale pricing.
The high end is also not immune to the rate environment. It is just insulated from the worst of it. Boston luxury condo sales in the first quarter of 2026 came in at 100, down from 146 in the same quarter of 2022. The median luxury price slipped about 7 percent year over year to $3 million, and price per square foot eased about 4 percent to $1,698. “Insulated” means it held while the rest of the market dropped. It does not mean it went up.
The market that actually collapsed
Now the other half of the story, the half that gets buried whenever the conversation is all trophy towers.
The real transaction collapse in Boston is not at the top. It is in the middle. George Sarkis, who runs a large team at Douglas Elliman, told Banker & Tradesman that the $500,000 to $2 million segment, the actual working condo market in this city, is “really struggling.” The volume numbers back him up. Citywide condo sales peaked at 5,922 in 2021, when mortgages were near 3 percent. They fell every year after the 2022 rate hikes, down to 3,496 in 2025. The first quarter of 2026 recorded just 598 closed condo sales, one of the slowest starts in years.
That drop has nothing to do with the luxury pipeline. A cash buyer shopping a $2,500-per-square-foot residence at the St. Regis was never going to buy a $650,000 two-bedroom in Roslindale or East Boston instead. These are two different markets with two different buyers. The top runs on cash, so rates barely register. The middle runs on financing, so a jump from 3 percent to 6.5 percent is the whole ballgame. Sue Hawkes of The Collaborative Companies said the majority of buyers active right now are paying cash, which tells you exactly who got pushed out. The financed buyer is on the sidelines, waiting on rates. Ending new luxury construction does not bring that buyer back. Only affordability does.
How to read this depending on who you are
So what do you do with all of this? It depends entirely on which of these two markets you are standing in.
| If you are… | What the end of the pipeline means | The move |
|---|---|---|
| An owner in an established full-service building (Seaport, Back Bay, Downtown Crossing, Fort Point) | Real, durable scarcity value as new supply ends, but on a delay while today’s new inventory clears. | Price to current comps, not to a headline. The leverage builds over the next few years. Do not front-run it. |
| A buyer holding out for something newer | After One Harbor Shore and 55 India Street, “newer” is not arriving for years. | Recalibrate the timeline. Either buy the last new product now or accept that a recent resale is your new-construction option. |
| Buying or selling in the $500K to $2M range | The pipeline story does not apply to you. Your market is set by mortgage rates and affordability. | Sellers, price to reality. Buyers, you have negotiating room the top of the market does not. |
| An investor watching the high end | The scarcity is narrow and building-specific, not a citywide thesis. | Underwrite the specific building and its absorption, not “Boston luxury” as a category. |
The bottom line
Boston is genuinely closing out its luxury condo pipeline. One Harbor Shore is the last major tower on the water, 55 India Street is the last boutique building downtown, and nothing serious is behind them for years. That is a real event. For a specific set of already-built waterfront and downtown buildings, it is good news that will compound quietly over the next several years.
But “no new luxury supply” and “rising prices everywhere” are not the same sentence. One is about a dozen buildings. The other is about a whole city, and most of that city is still governed by mortgage rates, not crane counts. Confusing the two is how a seller in a mid-market building prices for a boom that is not happening to them, and how a buyer talks themselves into overpaying out of fear of missing a shortage that was never in their segment.
The scarcity is real. It is just narrower than the headline makes it sound. Know which market your specific unit or search sits in before you set a price or write an offer.
