Why Hillsboro Beach's Median Home Price Is Nearly Useless for Buyers

In May 2026, an oceanfront estate at 1091 Hillsboro Mile sold for $27.8 million. That same month, three months of closings across the entire town of Hillsboro Beach produced a median home price of just $507,000, down close to 19 percent from the same window a year earlier. The typical listing was taking 126 days to sell, up from 98. Only 23 homes changed hands in the whole town that month.

The estate segment kept running hot through the summer. In August 2026, a second oceanfront estate at 1105-1107 Hillsboro Mile changed hands for roughly $40.9 million, Broward County's largest home sale so far this year. The buyer, Mason Paul Slaine, chairman of Cast and Crew Entertainment Services, purchased through a trust. The seller was a trust tied to Dr. David Cotton, who built Meridian Health Plan and sold it to WellCare for $2.5 billion in 2018. The house: 10,100 square feet on 2.35 acres, completed in 2021, seven bedrooms, eight and a half baths, a theater, a fitness room, an eight-car garage, a pool. It last sold for $20 million in 2021, and its value has since more than doubled, working out to roughly $4,059 per square foot of house and about $681 per square foot of the underlying land.

Read only the median and you would guess Hillsboro Beach was cooling that spring. Read only the estate sales and you would guess the town was on fire all year. Both readings are correct. Neither one is describing the same market, and knowing why matters more than knowing either number.

Why the Median Can't See the Record Sale

A median is built to ignore its outliers. Neither the $27.8 million May closing nor the $40.9 million August closing pushed Hillsboro Beach's median up. Medians describe the middle of a distribution, not its edges. When the vast majority of a town's transactions are older condominiums selling in the low hundreds of thousands, and a handful of ocean-to-Intracoastal estates trade only once every few years, those estate sales are statistically invisible to the figure everyone quotes, even as they set the ceiling for what land on this stretch is actually worth.

This is the part a spreadsheet comparison misses. Hillsboro Beach isn't one market with a soft patch. It's two markets sharing a zip code, and the statistic most people rely on was never built to describe both at once.

Two Markets, One Address

Hillsboro Mile itself holds roughly 60 private single-family estates, most with ocean frontage on one side of A1A and a deeded Intracoastal lot across the street for dockage. Everything else in town is condominium stock, much of it built before 1980, with pricing in most buildings running somewhere between the high $200,000s and the low $900,000s depending on floor, view, and how recently the building renovated. That second group produces the volume behind the town's headline median. The first group produces its headline sales.

A regional condo report published in February 2026 that grouped Hillsboro Beach with neighboring Deerfield Beach found a similar pattern from a different angle: 14.0 months of supply, median sale price down 4.5 percent to $615,000, price per square foot down a smaller 2.1 percent to $547, but total sales up 28.6 percent. Price and volume were pointing in opposite directions in the same report. In a market this thin, that isn't a contradiction. It's what happens when a small number of transactions gets asked to represent an entire town.

The Building That's About to Test the Math

Related Group and Dezer Development finished vertical construction on Rosewood Residences Hillsboro Beach in February 2026, the first large-scale new-construction condominium to break ground on this stretch in years. The project sits on 12 acres between the Intracoastal Waterway and the Atlantic, split into a 70-unit beachfront tower and a 22-unit Intracoastal building, with residences ranging from 2,800 to 6,400 square feet. Arquitectonica designed the architecture; Studio Piet Boon handled interiors. Amenities include a private marina with 14 slips, resort-style oceanfront and sunset pools, and a wellness center with a spa. Pricing at topping off began at $5.95 million. By spring 2026, the penthouse collection was being marketed starting near $16.5 million, with completion targeted for early 2027 and initial closings expected to begin late this year.

Here's what that means for the math above. Once those closings start recording, they'll enter the same pool of "homes sold" that produced a $507,000 median from 23 transactions in a single month. A handful of $6 million-plus closings landing alongside a dozen older condo resales won't move the median much. Medians resist exactly that kind of disruption by design. But they will move the average sharply, and any appraisal or listing presentation that leans on "recent comparable sales in the immediate area" needs to specify which area it means. A brand-new, resort-operated tower and a 1970s low-rise two buildings down are not comparable on a price-per-square-foot basis, no matter how close they sit to each other on the map.

What to Ask Instead of the Median

If you're comparing Hillsboro Beach to another coastal town using a single price figure, ask three questions before you trust it:

• Which segment is this number describing? A condo resale and a Hillsboro Mile estate are effectively different asset classes trading in the same zip code.
• How many sales is the number built on? A town moving 16 to 23 closings a month can see its median swing meaningfully based on which few properties happened to close.
• How recently was the comparable building's data pulled? A comp from Rosewood Residences tells you nothing about resale value in an older building nearby, and vice versa.

A Few Straight Answers

Is Hillsboro Beach's market actually slowing down? Not uniformly. Condo resale pricing and volume softened in the spring of 2026, and the estate segment went on to set a Broward County sales record that summer. The honest answer depends entirely on which segment you're asking about.

Will Rosewood Residences change what my existing condo is worth? It may raise the profile of the address, but an appraiser pulling comps for an older building should not be pulling from a newly built, resort-branded tower priced from $5.95 million. If you're planning to sell or refinance in the next year, ask specifically which comps your appraiser used.

How many single-family estates actually exist on Hillsboro Mile? Roughly 60. With a pool that small, annual turnover is naturally low, which is exactly why one or two sales can define the town's headlines for an entire year.

If you're weighing a purchase on Hillsboro Mile, comparing it against a nearby town, or trying to figure out what your own property here would actually fetch given how thin this market runs, a single median won't get you there.
