Miami-Dade County recorded 24 closings above $30 million in the first half of the year—more than New York and the San Francisco Bay Area combined for properties at that threshold. The count is small in absolute terms, but the reversal is structural. Three years ago, Miami closed seven transactions in this bracket for the full year.
The pattern holds when you separate condos from single-family homes. Fifteen of the 24 deals were standalone houses, the rest high-floor condos along Brickell and Miami Beach. New York managed 11 total closings over $30 million in the same period; the Bay Area logged 9. This is not tax arbitrage alone—family offices are building second headquarters, not vacation homes. The buyers are installing private offices, bringing compliance staff, and negotiating data-center co-location agreements with local firms.
Three factors converge. First, Florida's lack of state income tax remains table stakes, but the expiration of the federal SALT deduction cap in 2025 did not reverse the trend. Allocators who moved in 2021 and 2022 stayed. Second, Miami's private aviation infrastructure now handles 41% more international departures than it did in 2023, according to county airport authority filings. The wealth is not just domestic—it is Latin American, European, and increasingly Middle Eastern. Third, the development pipeline for properties above $25 million is not slowing. Eighteen new listings in this bracket came to market in July alone, and twelve are pre-construction.
The implication for allocators is straightforward. Capital is moving, but so is the service infrastructure that follows it. Private banks are opening Miami wealth advisory desks. Art storage facilities are expanding climate-controlled square footage. The secondary markets—interior designers, estate attorneys, family office recruiters—are all pricing in permanence, not speculation. When Sotheby's opens a dedicated Miami auction house in Q4, it will not be a satellite. It will be a primary venue.
Operators and allocators should watch three follow-on events. First, whether New York's ultra-luxury inventory begins discounting in Q4 as sellers realize the bid has migrated. Second, whether Miami's new supply above $25 million absorbs without price concessions through year-end—eighteen listings is not small for a market this thin. Third, the pace of family office registrations in Florida; the state processed 1,142 new SFO entities in 2025, and the first half of this year is already tracking 20% ahead.
The count is 24. The trend is not.
