A $32.5 million beachfront mansion in Golden Beach. A $21.6 million condo at the Estates at Acqualina in Sunny Isles Beach. A $170 million compound on Indian Creek Island.

Twenty-nine single-family homes sold for $30 million or more across Miami-Dade in 2025, shattering the previous record of 15 set in 2024, according to a new Analytics Miami report covered by the Miami Herald Wednesday, July 29. Already in the first half of 2026, 21 homes have crossed that threshold. Before 2020, no more than three sold per year at that price point.

When condos are included, the numbers climb higher. Miami-Dade logged 24 sales above $30 million in the first half of 2026, nearly double the same period a year earlier, according to Bloomberg data cited by the New York Post. That outpaced New York City's 17 and the San Francisco Bay Area's nine. The majority were cash deals.

Total real estate spending in Miami-Dade hit $13.7 billion in the first half of 2026, up 19% from the same period in 2025 and 101% above pre-pandemic levels, according to Analytics Miami founder Ana Bozovic.

"We're at price points that did not exist pre-COVID," Bozovic told the Miami Herald.

Tax flight from New York and California fuels the surge

Bozovic attributes the surge to wealthy buyers fleeing high-tax states. New York City's pied-à-terre tax took effect in July 2026, and a proposed California billionaire wealth tax targeting those who lived in the state as of Jan. 1, 2026, is set for the November ballot, according to Insurance Journal. Buyers from those cities are accustomed to paying more for housing, which pushes Miami prices higher.

The tech billionaire wave has been dramatic. Meta CEO Mark Zuckerberg purchased an Indian Creek Village mansion for $170 million earlier in 2026, setting the county's all-time record. Google co-founder Sergey Brin bought a Miami Beach waterfront property for $51 million in March 2026. Brin, fellow co-founder Larry Page, and Zuckerberg all closed South Florida deals within roughly 60 days of each other.

Dina Goldentayer, a Douglas Elliman agent who closed the $32.5 million Golden Beach mansion sale, described the buyer pool to Bloomberg: "This level of tech wealth is in a different stratosphere. There are such elite players now."

Collins Avenue cashes in on the ultra-luxury boom

The wealth is landing on Collins Avenue. A six-bedroom condo at the Estates at Acqualina, 17901 Collins Ave., sold for $21.6 million in early July 2026, according to The Real Deal. At $2,800 per square foot, the unit gained roughly 21% over its 2025 purchase price of $17.9 million.

Meanwhile, Bentley Residences Miami at 18401 Collins Ave. reached Level 7 of vertical construction in June 2026, according to developer Dezer Development. The 62-story tower is on track for a 2028 opening, with 216 residences starting at $5.8 million and two penthouses priced at $37.5 million each. Dezer Development secured a $630 million construction loan from Madison Realty Capital for the project.

As we reported July 23, the broader luxury tier averaged $3.61 million per sale in the second quarter of 2026. The $30 million-and-up segment operates in a different universe, but agents say the wealth migration lifting it is raising prices across the corridor.

Devin Kay, a Douglas Elliman agent who has sold luxury homes in South Florida for 14 years, told the Herald that $30 million sales used to be rare. Now they happen monthly, he said, and deals are pushing past $100 million.

Tight inventory keeps prices climbing despite the cooldown that came before

Single-family home inventory across Miami-Dade remains 30% below pre-pandemic levels, according to the Analytics Miami report. Corcoran Group agent Mick Duchon, who was involved in the sale of two neighboring Venetian Islands properties for $33 million in June 2026, said ultra-luxury prices held steady even when pandemic-era demand cooled. Now that demand has returned, prices are climbing again.

Bentley Residences' 2028 completion will add the corridor's next wave of ultra-luxury inventory to the market.
