Broward County's priciest home sale of 2026 just closed on the Hillsboro Mile, landing just under the street's all-time record.
Key Takeaways
- The oceanfront estate at 1105-1107 Hillsboro Mile sold for about $40.9 million, Broward County's top home sale of 2026.
- The property last sold for $20 million in 2021, so its value more than doubled in roughly four years.
- The deal worked out to $4,059 per square foot for the house but only $681 per square foot of land, a sign that the location is the real asset.
South Florida's luxury market has cooled from its peak, but nobody told the Hillsboro Mile. Broward County's most expensive home sale of the year just closed on this narrow barrier-island strip, and it is the kind of trophy trade that keeps happening here even when the rest of the market slows. According to The Real Deal, the oceanfront estate at 1105-1107 Hillsboro Mile sold for about $40.9 million, changing hands between two very different fortunes.
What sold, and who bought it?
The home is 10,100 square feet on 2.35 acres, completed in 2021, with seven bedrooms, eight and a half baths, a theater, a fitness room, an eight-car garage, and a pool. At roughly $40.9 million, that works out to about $4,059 per square foot, which is not cheap. The more eye-catching number is the history: the same property last sold for $20 million in 2021, so it more than doubled in about four years.

The seller was a trust for David Cotton, M.D., who founded Meridian Health Plan with his wife Shery in 1997 and sold it to WellCare for $2.5 billion in 2018, a deal that left the family with roughly $2 billion after taxes. The buyer, also using a trust, is Mason Paul Slaine, chairman of Cast and Crew Entertainment Services and former co-owner of FT Media Holdings. Chad Carroll of Compass held the listing, and Senada Adzem of Douglas Elliman represented the buyer.
Why did a fairly plain house sell for $40.9 million?
Here is where the story gets interesting. The house itself is not a showpiece, and the buyer is not really paying for the finishes. The tell is in the two price-per-square-foot figures: $4,059 per foot of house, but only $681 per foot of land. On the Hillsboro Mile, the land does the heavy lifting, because these lots offer something almost impossible to find anywhere else in Broward. You get direct beachfront on one side and more than 100 feet of Intracoastal frontage on the other, which means you can walk to the ocean and dock a serious boat behind your house.
That combination is the whole game for ultra-wealthy buyers. As Larry Mastropieri explained on the Discover South Florida Podcast, the appeal is a pairing that is genuinely hard to source: "They want the beachfront, but they also want to park their big yacht. There aren't many places where you can get mega yacht parking in South Florida."
Most canals are too tight to turn a 100-foot yacht, and backing one out can send insurance costs up by tens of thousands a year, so a lot that solves both problems commands a premium. It is the same reason a modest lot can carry an enormous price, a pattern we broke down when a $1.5 million lot became a $100 million deal in West Palm Beach. For owners weighing what their own frontage is worth, our guide on docks and seawalls is a good place to start.

How does the sale rank on the Hillsboro Mile?
This deal came close to making history. The all-time Hillsboro Beach record is $42.5 million, set in late 2018 by the Playa Vista Isle estate at 935 Hillsboro Mile, a 33,200-square-foot mansion that had been listed for years and at one point asked $159 million. So the $40.9 million sale fell just shy of the top. Still, it easily beat the street's prior 2026 leader, an ocean-to-Intracoastal mansion that sold for more than $36 million in January to a trust tied to New Jersey homebuilder Morris Flancbaum.
It also outpaced the more routine trophy trades on the strip, like 1091 Hillsboro Mile, which sold for $27.8 million in May 2026. Put together, these sales tell a consistent story. Even with the broader luxury market slowing, the Hillsboro Mile keeps moving trophies, and it now holds Broward's biggest deal of the year.
More on Hillsboro Mile
The Hillsboro Mile (previously known as "Millionaire Mile," now "Billionaire's Mile") is a roughly three-mile barrier-island strip in Hillsboro Beach, running along A1A between the big estates of Boca Raton and the new oceanfront condos of Pompano Beach. With the ocean on one side and the Intracoastal on the other, it is one of Broward's most private and expensive addresses, and it carries the highest home values in the county. That mix of scarcity and privacy is why it keeps drawing wealthy buyers year after year. The same city has also drawn headlines for a resort foreclosure and the new Rosewood Residences.

Frequently Asked Questions
Where is the Hillsboro Mile?
It is a roughly three-mile barrier-island strip in Hillsboro Beach, Broward County, running along A1A between Boca Raton and Pompano Beach. It has the ocean on one side and the Intracoastal Waterway on the other, which is why it is prized for both beach access and boat dockage.
What is the most expensive home ever sold in Hillsboro Beach?
The record is $42.5 million, set in late 2018 by the Playa Vista Isle estate at 935 Hillsboro Mile. The 33,200-square-foot mansion had been listed for years and once carried an asking price of $159 million. The recent $40.9 million sale came close but did not break it.
Why are Hillsboro Mile homes so expensive?
The value is in the land more than the house. These lots offer direct beachfront plus deep-water Intracoastal frontage, a combination that is very hard to find in South Florida, especially for owners who want to dock a large yacht. Scarcity and privacy push prices to the highest levels in Broward County.
Who bought the $40.9 million Hillsboro Beach mansion?
The buyer was Mason Paul Slaine, chairman of Cast and Crew Entertainment Services and former co-owner of FT Media Holdings, who purchased through a trust. The seller was a trust tied to David Cotton, M.D., who built and sold Meridian Health Plan to WellCare for $2.5 billion in 2018.
Can you dock a large yacht in South Florida?
It is harder than most people expect. Many canals are too narrow to turn a 100-foot boat, and backing one in and out can sharply raise insurance costs. Lots with wide, deep-water frontage that can handle a mega yacht are rare, which is a big part of why waterfront estates like this one trade at a premium.
