Ask three sources what's happening to home prices on the island of Palm Beach right now and you'll get three different answers. Redfin's data for the three months ending in May 2026 puts the median sale price at $2.6 million, down 23.6 percent from the same stretch a year earlier. Zillow's home value index for the same market, updated through June 30, 2026, shows the average home value at $2,145,595, down just 1 percent over the past year. Neither number is wrong. Both are measuring a market so small that a single closing can move the headline.
That distinction matters if you're a New Yorker weighing a purchase on the island, in West Palm Beach across the bridge, or somewhere in between. The "Mamdani effect" story you've probably already read, the one about New York buyers flooding south since the mayor's June 2025 primary win, is real in the sense that agents are fielding more calls. But the price data underneath that story doesn't move the way a normal market's would, and understanding why changes what you should actually watch before you write an offer.
Same Nine Square Miles, Two Different Headlines
Here's what the numbers looked like heading into this fall.
| Source | Metric | Figure | Window |
|---|---|---|---|
| Redfin | Median sale price | $2.6M | Trailing 3 months through May 2026, down 23.6% year over year |
| Zillow ZHVI | Estimated average home value | $2,145,595 | As of June 30, 2026, down 1.0% year over year |
| MLS-sourced local analysis | Median single-family house sale | $11,278,000 | August 2026, based on 10 closed sales |
| MLS-sourced local analysis | Median condo or townhouse sale | $920,000 | August 2026, based on 15 closed sales |
A market this small produces numbers this jumpy because there simply aren't enough transactions to smooth anything out. One local analysis of BeachesMLS data widens its reporting window to the trailing three or twelve months whenever fewer than five sales close in a given month, and even then it's working with a total of 386 Palm Beach sales across the full twelve months ending August 2026, split roughly 26 percent houses and 74 percent condos and townhouses. When your entire annual house sample is a few hundred transactions and the segment includes both a renovated cottage and an oceanfront estate, the median isn't a trend line. It's whichever handful of deals happened to close that month.
This is the part most coverage skips. A 23 percent year over year drop sounds like a market in trouble. An index showing 1 percent decline sounds like stability. Both can be true at once when the sales mix shifts even slightly, because a market built on ten house closings a month doesn't behave like a market built on ten thousand.
The Island Stopped Building Decades Ago, and That's Starting to Crack
The reason Palm Beach sales stay this thin isn't demand. It's land. The Town of Palm Beach hasn't approved a new condominium building in decades, and virtually every parcel on the island is already spoken for. What's changing in 2026 isn't new supply, it's what happens to the old supply.
Developers are now eyeing existing buildings on the island with plans to tear them down and replace them with fewer, larger units, a pattern that shrinks unit count even as it raises price per square foot. Across the Intracoastal in West Palm Beach, a parallel version of this is playing out at scale. The Boca Raton Tribune reported this month that affiliates of Related Ross and Fort Partners have been competing to buy out condo units at Harbor Towers Condominium and Marina on South Flagler Drive, with the aging Flagler Yacht Club and Regency Surf & Racquet Club nearby also drawing buyout interest from developers.
That distinction between the island and the mainland matters for anyone comparing the two. On the island, a teardown replaces an older building's full roster of units with a smaller count of larger ones on the same footprint. The parcel count never grows. Across the bridge, West Palm Beach is doing both things at once: buying out aging waterfront buildings and adding genuinely new towers where none existed before.
The Real Inventory Growth Is Across the Bridge
If you want to see where net new supply is actually landing, look at South Flagler Drive and North Flagler Drive in West Palm Beach, not the island itself.
Related Ross's South Flagler House became the first condominium development in West Palm Beach to surpass a billion dollars in total sales, with units trading around $6,000 per square foot and a reported $40 million penthouse purchase by former Apple CEO John Sculley among a batch of deals approaching $70 million combined, according to Robb Report's March 2026 coverage. The same firm is now building Edgeworth one block away: two curved 28-story towers with 168 residences and nine penthouses, priced from $2.5 million, with construction set to begin in 2027 and completion projected for 2029.
Other projects are filling in around them. The Ritz-Carlton Residences, which targeted a first-quarter 2026 groundbreaking, has remaining units priced from $3 million. Nora House, part of a billion-dollar mixed-use district, is pricing in the upper $1 million range. Shorecrest, a 27-story tower approved for a two-acre site at 1901 North Flagler Drive, sits on land currently occupied by Temple Israel, which will be relocated and its building demolished to make way for the new tower. The West Palm Beach Planning Board approved the project at a lower density than the 199 units originally proposed, landing at 100 residences.
Put together, this tells you something the median price can't: the island is a fixed, shrinking-unit-count market where scarcity does the pricing, and the mainland is where an actual construction cycle is absorbing new buyers. If your budget sits comfortably above eight figures and privacy matters more than square footage, the island's math applies to you. If you're closer to the one to three million dollar range and want new construction, you're really shopping West Palm Beach, whatever the listing says the ZIP code is.
What the Migration Numbers Actually Show, and Don't
The agent-reported surge is genuine as far as it goes. Palm Beach agents reported New York buyer inquiries up 50 percent and luxury listing views up 75 percent following Mamdani's June 2025 primary win, and one report tracked a single November 2025 week with 29 high-end properties going under contract and $235 million in asking volume, up sharply from the prior week's $67.7 million across ten contracts. Westchester brokers separately reported a 15 percent year over year jump in contracts over roughly the same period. The Business Development Board of Palm Beach County leaned into it, mailing 500 relocation packets to New York firms and putting up a Times Square billboard reading a line about not being New York's fault, just a change of scenery.
That's one slice of the buyer pool. A wider one is moving the opposite direction. Foreign buyers purchased $45.3 billion worth of existing US homes between April 2025 and March 2026, a 19.1 percent plunge in dollar volume and the second-lowest transaction count since the National Association of Realtors began tracking the data in 2009, Fortune reported this July. In that same period, New York fell out of the top five state destinations for international buyers entirely, replaced by New Jersey and Georgia. Domestic relocation interest and international investment appetite are two different currents, and right now they're running in opposite directions. Neither cancels the other out, but citing one without the other gives you half a market.
The Pied-à-Terre Math Changed at Home Too
There's a piece of this that applies directly if you already own in New York and are weighing a second address in Florida. Earlier this year, the city's Department of Finance published a searchable database listing every property potentially subject to New York's new pied-à-terre tax, covering non-primary residences valued at a million dollars or more. City Hall projects the levy could raise as much as $500 million a year, while the comptroller's office estimates a range closer to $340 to $380 million. Whatever the final number, if you're holding a New York apartment as a secondary residence while shopping in Palm Beach, that unit is now part of a public list, and the ownership math on keeping both addresses looks different than it did eighteen months ago.
What This Means If You're Actually Comparing the Two
Don't let any single month's median tell you the island is up or down. With house sales in the single digits some months, one estate closing swings the number by seven figures. Watch the buyout activity on South and North Flagler Drive instead. That's where you'll see which older buildings are getting priced out of existence and which developers are willing to pay for the land under them, which tells you more about where value is concentrating than any index update.
If your budget points you to the mainland, you're buying into an active construction cycle with real competition among towers for your deposit. If it points you to the island itself, you're buying into permanent scarcity, and the relevant question isn't whether the median moved last month but whether the specific building you're looking at could be next in a buyout line.
And if you're still holding a New York address as a pied-à-terre while you shop, run the tax exposure before you run the comparison on square footage.

A Few Questions Worth Asking Before You Shop
Is the island of Palm Beach or West Palm Beach the better fit for a New York buyer right now? It depends on budget and what you're optimizing for. The island offers fixed scarcity and privacy at eight figures and up. West Palm Beach offers new construction, lock-and-leave convenience, and a wider range of entry points starting around $2 million to $3 million in current preconstruction pricing.
Does the new NYC pied-à-terre tax affect me if I already own here and I'm just buying a second home? If your New York property is valued at $1 million or more and isn't your primary residence, it's part of the database the city published this year. Confirm your specific exposure with a tax professional before treating a Florida purchase as a simple addition to your portfolio.
Should I wait for Palm Beach prices to fall further based on the headline numbers? The headline numbers disagree with each other for a reason: there aren't enough monthly sales on the island to produce a stable trend. A single index update isn't a strategy. Watching which buildings are drawing buyout interest, and which mainland towers are moving through their sales pace, tells you more than waiting on next month's median.
