Fisher Island Tops U.S. Zip Codes for Home Prices at $9.5M Median

PropertyShark's 2025 rankings reveal that Florida's Fisher Island has become the most expensive zip code in the United States, with a median home sale price of $9.5 million, surpassing California's Atherton, which had held the top spot for nearly a decade. Fisher Island's exclusivity is heightened by its lack of a bridge to the mainland, making it accessible only by yacht, helicopter, or a frequent ferry, attracting wealthy individuals and celebrities. New Jersey and Massachusetts also saw multiple zip codes among the nation's priciest, with New Jersey's Alpine leading at $4.35 million and Massachusetts' Boston Back Bay area featuring prominently with median sales around $2.4 million. California continues to dominate with eight of the top ten highest median home prices, largely in coastal areas. The high-value zip codes across the country are predominantly coastal or island locations, reflecting a trend towards luxury real estate in exclusive, scenic areas. Additionally, Florida cities like South Pasadena, St. Pete Beach, and Stuart rank highly for safety, income, and livability, complementing the state's appeal for affluent residents.
