Fisher Island Tops America’s Wealthiest ZIP Codes in 2025 PropertyShark Ranking

The 2025 PropertyShark report on the nation's 100 priciest ZIP codes reveals a significant shift in luxury real estate rankings, with Fisher Island in Miami Beach, Florida, dethroning Atherton, California, as the most expensive ZIP code. Fisher Island's exclusivity, combining seclusion and scarcity, commands a median home price of $9.5 million, surpassing Atherton's $8.33 million. The Northeast, traditionally strong in luxury markets, showed its weakest performance in a decade, with New York placing 15 ZIP codes in the top 100, Connecticut a record seven, and Massachusetts only four. The Hamptons dominate New York's rankings, led by Sagaponack and Water Mill, while Greenwich, Connecticut, ties with Los Angeles as the second-most-expensive city nationwide. New Jersey maintains a robust presence with six ZIP codes, including Alpine, which ties Beverly Hills at 13th place with a median home price of $4.35 million. Meanwhile, Boston's luxury market declined, reaching its lowest median sale price in a decade.
