What Makes a New Building Hold Its Value

What Changed

The current pipeline is selling into a different county from the one that received the last wave. Closed sales of $20 million and up went from ten in 2020 to thirty-six in 2025. Their price per square foot rose 37 percent, the steepest climb of any tier. Lower down, the buyer's dollar shrank at every level. The median purchase between $10 million and $20 million cost $1,650 per square foot in 2020 and $2,145 in 2025. Our five-year county comparison tracks that compression tier by tier.

The sharpest change sits on the water. In 2020 a buyer at $1 million to $2 million had better-than-even odds of ocean or Intracoastal access. By 2025 those odds did not reach half anywhere below $10 million in the record of closed sales. Meanwhile the pipeline has grown to sixteen projects selling or rising this September, 1,834 new residences in all, with published entry prices from $1.6 million to $8.5 million. Our new-development map places each one beside the recorded evidence, and our new developments pages carry their details.

What Never Changed

Through all of that movement, the buildings that held their value share four characteristics, and each one is documented in the closed record. They are short supply, a defining location, construction that still feels like luxury years on, and a developer who had finished buildings before. Our Bristol appreciation study works through the framework in detail. The chart below puts its clearest case beside the county at large, and the table that follows grounds each of the four.

Short supply comes first because it cannot be manufactured after the fact. The Bristol holds 69 residences with no second phase and no comparable site beside it, and no resale there has closed below $2,786 per square foot since 2022. SeaGlass holds 21 oceanfront residences on a stretch of Jupiter Island where nothing like it stands, and all five of its resales closed above the developer's price. The island around it shows how supply becomes permanent. Both of its wild ends passed into permanent conservation by 1969, including 73 oceanfront acres given to The Nature Conservancy. The full account is in our history of how Jupiter Island stayed wild.

A defining location is the second condition. The Bristol stands on the last premium site of South Flagler Drive, and our studies measure other West Palm Beach luxury buildings against its record. Our five-year county comparison documents how scarce that kind of location has become.

True luxury is a construction standard, and it shows in the closed record. The Bristol's ceiling heights, private elevators and amenity floors still feel current seven years after delivery. Every resale above its 19th floor has cleared $2,900 per square foot or more. The gap shows most plainly where old and new stand side by side. In one north county golf community, estates built in the 2000s resold at $1,434 to $1,823 per square foot since early 2025. Two of the community's three recent new builds closed at $2,938 and $3,099, roughly double per foot for construction at the current standard. Our study of the $3,000 threshold covers that record in full.

A developer's finished buildings are the one part of a sales gallery a buyer can verify. SeaGlass came from a developer who completed the building and recorded all 21 closings inside ten days. The Bristol's developers delivered a specification that still competes with everything built after it. An unproven developer may go on to do the same. Nothing in the record shows it yet. That is the gap between a proven developer and an unproven one: recorded closings and standing buildings behind the first, neither behind the second.

The Other Side of the Record

Prices set ahead of the recorded closings have come back to them. No current project can serve as the example, so the pattern has to be stated in general terms. In our north county pricing study, sellers who asked close to recent sales collected 92 to 97 percent of the asking price. Sellers who asked far above them did worse, one collecting 64 percent, and one new build that asked $25 million closed at $15.5 million.

Momentum faded even at a proven building. Resales at SeaGlass stepped down from $2,964 per square foot in 2023 to $2,094 on the newest closed sale. The owners who waited longest, 831 and 923 days across repeated listings, still closed above the developer's price.

Scale raises its own questions. The smallest count on the current pipeline is 28 homes. Our comparison of that project with the 75 resort residences across town weighs what a small building gives its owners against its thin resale supply. The corridor holding the most projects, four of them, has no established building with a recorded sales median at all. That is a statement about evidence rather than about any project. One of the sixteen has delivered, and its open listings are already resales. None of the fifteen still selling has a resale record yet.

Three Seats at One Table

From the buyer's seat, the gallery visit is built to persuade. The model is lit, the finishes are real, and the gallery team's job is to present the building at its best. There is nothing wrong with that, and the good ones do it well. Our job in that room is to bring the recorded closings for the corridor, the developer's finished buildings, and the questions the brochure does not raise. We have no stake in any one project's presentation, whichever building a buyer chooses. The decision belongs to the buyer.

From the developer's seat, we learned how the numbers are set. An asking sheet reflects land cost, construction cost and the need to sell an unproven address, which is why it usually runs ahead of the recorded closings nearby. Working those programs taught us respect for how much a developer risks, and it taught us that every figure on the sheet is an asking figure until a sale closes.

From the resale seat, we see the outcome years later. When an owner sells, the gallery is long closed, and the building competes on its supply, its address and how its construction has aged. At resale the price reflects the building as it stands and the closed sales around it. The Bristol's resales and SeaGlass's resales show exactly this pattern, and both buildings carried the four fundamentals from the start. Our aim at every gallery we visit with a client is a decision informed by the closed record.

Reading the Current Pipeline

Applying the fundamentals to the current pipeline mostly consists of questions. How many residences, and can the count grow nearby? Does the address define its corridor, or does the corridor still need defining? Which finished buildings carry the developer's name, and how has their construction aged? What have the recorded buildings nearby closed at, and how far above those closings does the asking sheet sit? Our map of the sixteen projects holds recorded medians beside every one of them. Our guide to buying new construction covers each contract step once a buyer has chosen a building.

One habit serves buyers at every project on that map. Read the corridor's recorded closings first, decide what the four fundamentals say, and take that reading into the gallery rather than forming one there.
