In This Report
The Market You Can See
Every portal is built from listings. Zillow and its peers republish what brokerages enter into a multiple listing service, the shared database where homes are listed and closed sales are recorded. Most of coastal Palm Beach County uses one big regional board, BeachesMLS. The Town of Palm Beach also keeps a second board of its own, and we return below to what that split does to the record.
A sale that skips both boards never reaches a portal at all. Not as a listing while it sold, and not as a closing afterward. The buyer was found privately, and the first public evidence is the closing itself.
That evidence is worth understanding, because nothing about it is hidden. It simply lives somewhere most people never look.
Where Every Sale Leaves a Record
No sale closes without a deed, the document that transfers ownership from seller to buyer. Every deed here is recorded with the Clerk of the Circuit Court and Comptroller, the county's keeper of official records. That record is public. Anyone can search it, book and page, back across a century.
The Property Appraiser reads those recordings too. Each sale is posted to the property's page in the appraiser's public database, with a date, a price and a grade for the sale itself. Our Martin County studies rest on the same system there.
Our method lays this deed record over both boards. We pull every qualified sale from the appraiser's roll, then look for a matching closed sale on each board. A deed with no closing on either board is a quiet sale, and those are the sales this report counts. The card below is the whole idea in one picture.
- BeachesMLS: the regional board. This is what Zillow and the portals read.
- Palm Beach Board of Realtors: the town's own board since 1949. Some listings sit only here.
- The county deed record: every sale that closes, including sales on neither board.
Board coverage from our two-boards study of the Town of Palm Beach: reading BeachesMLS alone missed 22 percent of recent listed sales, the town board alone missed 30 percent.
What the Stamp Tax Tells
There is a catch, and it surprises people. The price is not written on the deed. Custom at this level is to state ten dollars and other good and valuable consideration, so the number everyone wants appears nowhere in the document.
The tax collected at recording gives it away. Florida charges a documentary stamp tax of seventy cents per hundred dollars of the true price on nearly every deed, and the amount paid is part of the public record. Divide the tax back out and the price emerges, exact to the nearest hundred dollars.
Take a $9,000,000 purchase. It pays $63,000 in stamp tax at the courthouse door. Anyone reading the record can run that arithmetic in reverse, and that is how every private price in our studies was found. The price the appraiser posts comes from that same calculation.
One more filter matters before anything is counted. The appraiser grades every sale, and only sales graded as qualified enter our numbers. Qualified means arm's length: a willing buyer and an unrelated seller trading at a market price. Deeds between family members, transfers inside a divorce or an estate, and moves between an owner and their own company are all excluded first. What remains are real purchases by outside buyers at real prices. Those are the off-market sales this report measures.
- The deed states a nominal $10, the custom at this level.
- The stamp tax paid at recording is public record.
- Dividing the tax by the rate recovers the true price.
Florida documentary stamp tax on deeds: 70 cents per $100 of consideration in every county except Miami-Dade. The derived price is exact to the nearest hundred dollars.
What the Deeds Show
With the method in hand, here is what it finds. Each community below was measured by its own study, with its own window and price floor, stated beside each figure.
Start behind the gate at Lost Tree Village, where the gap runs widest. The Property Appraiser records 110 qualified sales of a million dollars and up there over five years, and the MLS records 61. The difference is 49 sales and $342M with no MLS closing, 45 percent of the sales and 39 percent of the dollars inside the gate. Anyone shopping from the listed inventory there sees a little over half the market.
The Town of Palm Beach runs the largest quiet market in the county. Since 2021 it has recorded 225 qualified house sales of $3M or more with no closing on either board, $4.1 billion in all. The private share peaked at 45 percent of the town's sale dollars in 2021. It has fallen since, to a low of 19 percent in 2025 and about 21 percent this year. A strengthening open market has been winning sellers back, with one exception. Above $50M, nearly every sale still closes on neither board.
Jupiter Island holds the same two markets in a steadier balance. Since 2016 the Town of Jupiter Island has recorded 81 qualified sales of a million dollars and up with no matching MLS closing, $589.1M in all. On the island itself, those quiet sales carry roughly 25 percent of the dollars. The share swings hard, from a measured high of 75 percent in 2016 to 3 percent in 2019 and back to nearly half in 2024. The island record itself, $58M for 450 South Beach Road in August 2025, closed on neither board. Jupiter Inlet Colony next door trades on the open market more often, yet about a fifth of its dollars since 2016 still moved with no MLS closing.
Atlantic Fields, the Discovery Land community in Hobe Sound, recorded 36 closings for $264.5M in its first year. Every one was raw land, at an average of $7.35M a parcel. Our study of that first year was built the same way as the rest of this page, from county deeds.

Why the Record Fragments
Nobody designed this to be hidden. The record simply lives in three places at once, and most of the coast lists on BeachesMLS. The Town of Palm Beach also keeps its own board, the Palm Beach Board of Realtors, chartered in 1949, and each listing goes wherever its brokerage chooses. In the two most recent years, only 107 of 227 closed sales in the town appeared on both boards. Reading BeachesMLS alone missed 22 percent of the town's open-market sales. Reading the town board alone missed 30 percent.
The blind spots reach the very top. A $122.7M sale in February 2021 was listed after all, though only on the town's own board, invisible to the regional feed most portals read. And beneath both boards sits the deed record, where the town's $155M record of March 2023 closed on neither board. Our two-boards study documents the full split. Nobody should price, bid or appraise here from one feed alone.
Why Sales Go Quiet
The reasons are ordinary, and they come from both sides. An estate settles, and the family prefers one clean transaction to a public process. A neighbor buys the parcel next door to protect or extend a compound, which is how many of the county's great holdings were pieced together. An owner with no plan to sell receives a well presented offer and accepts it. For sellers at this level, discretion has a value of its own. No photographs circulate and no days-on-market clock starts, though the deed itself still records publicly, stamp tax included.
Community structure decides where the quiet market concentrates. Club and gated communities, where members and neighbors trade among themselves, carry the highest quiet shares, and Lost Tree Village shows the county's widest measured gap. Open oceanfront markets carry the lowest, because the seller of an irreplaceable home wants the widest audience. Even the listed market has private deals running inside it. In the last twelve months, 190 of the county's 1,204 closings at $3M and up went under contract within a week, about one in six. A contract that fast leaves little room for a public search. Our county share analysis counts those closings as the pre-arranged lane, town by town.
How a Quiet Sale Runs
On the sell side, the process is more disciplined than the word quiet suggests. The sequence in our quiet listing playbook has four steps. A written valuation comes first, built from MLS closings and the deed record, so the private market's evidence is in the price. Then the route is chosen: a fully private sale, a Compass Private Exclusive, or quiet preparation for an open launch. A Private Exclusive shows the home to serious buyers inside the Compass network with nothing published. The decision comes last, made from that evidence.
The record puts numbers on both sides of the choice. Closings that found their buyer within a week kept a median 98.4 percent of the first asking price over the last year. Listings that took more than six months kept 84.5 percent, a gap worth about $1.4M on a $10M asking price. Discretion has a cost as well, because a fully private sale tests one buyer's price rather than the market's. On Jupiter Island, the sellers of 450 South Beach Road listed publicly at $90M in 2021, and the $58M closing four years later reached neither board. Tarpon Isle moved in the other direction, an $85M sale in 2021 with no MLS closing, then a return through the MLS at $152M in 2024.
Seeing the Whole Market
For a buyer, the point is coverage. A portal search reads one board, and in the communities above that can mean half the market or less. A serious search covers both boards, the deed record, and the owners who would consider a properly presented offer. Several sales in these studies began exactly that way, with a buyer naming what they wanted and an agent asking owners privately on their behalf.
Shopping can also start before the public market. As Compass agents we can show buyers Private Exclusives, homes for sale inside the network before anything is published. That completes the picture: the boards hold the listed market, the deeds hold the quiet one, and Private Exclusives open the one still forming. Much of our buyer work runs on all three.
For a seller, the deed record reframes the pricing conversation. Comparable sales pulled from listings alone understate values in every community where a large share of sales closes quietly, because the missing sales include the largest ones. A valuation should stand on every sale that recorded, from both boards and the deeds, which is how our seller services build them. An owner weighing discretion can start with a Private Exclusive before deciding anything public.
Bottom Line
Every sale here leaves a public record, including the ones no website ever showed. The deed gives the date, and the tax on it gives the price. The portals miss those sales entirely. Even the two boards shared barely half the town's recent sales with each other. A valuation built from one feed rests on part of the market, and the missing part holds the largest sales.
For anyone pricing at this level: Ask what the comparables counted. The good ones read both boards and the deeds.
Every measured figure on this page is reused from one of seven published Palm Beach Luxury studies, and each of those carries its own full methodology. The measurements lay county deed records over the boards' closed-sale records. Deeds are recorded with the Clerk of the Circuit Court and Comptroller in each county and read through each Property Appraiser's published sales roll, qualified arm's-length sales only. Prices follow from Florida's documentary stamp tax of seventy cents per hundred dollars, the statewide rate outside Miami-Dade. The boards are BeachesMLS and the Palm Beach Board of Realtors. A sale counts as off-market when a qualified deed records with no matching board closing inside each study's stated tolerance. Windows and price floors differ by study and are stated beside each figure.
The scope has honest limits. The measured communities are the Town of Palm Beach, Jupiter Island, Jupiter Inlet Colony and Lost Tree Village. The county-wide time-to-contract analysis rounds out the set. They are not the whole county, and no owner is named anywhere in the series. One further limit: a home held in a company can change hands by selling the company itself, and no new deed records. Sales of that kind sit outside every figure here.
