Boston – A new report by PropertyShark reveals that five of the most expensive zip codes in the United States are located in Massachusetts for 2025. These affluent areas highlight the ongoing demand for luxury real estate in the region, showcasing a blend of urban, island, and suburban markets.
The most expensive zip code in the state is Boston’s 02199, which ranks 54th nationally with a median sale price of $2.57 million. This zip code has made it onto the list for the seventh time in the past decade. Following closely is Nantucket’s 02554, ranking at 63rd, with a median sale price of $2.5 million, although it experienced a 14% decline year-over-year. Third on the list is Chilmark’s 02535 at $2.48 million, marking a new record high. Weston’s 02493 follows closely behind at $2.39 million, also setting a new record. Lastly, Wellesley Hills’ 02381 rounds out the top five with a median sale price of $2.25 million, just $50,000 short of a new all-time high.
The report indicates a broader trend where the most expensive housing markets in the U.S. are primarily coastal, with California dominating the luxury market. In fact, California accounts for 61% of the entries in the top 100 list. While Massachusetts retains a strong presence, other New England states are also represented, including Connecticut and New Hampshire. Connecticut’s 06878, located in Greenwich, ranks as the top entry from New England at 43rd, surpassing the highest Massachusetts zip code. In New Hampshire, New Castle’s 03854 ranks 50th with a median sale price of $2.65 million, which is higher than Boston’s 02199.
Nationally, the most expensive zip code is Miami Beach’s Fisher Island (33109), which holds a staggering median sale price of $9.5 million. This marks the first time that Florida has topped the list of expensive zip codes, making a significant impact on the real estate dynamics in the country.
The PropertyShark report analyzed residential transactions for various property types, including condos, co-ops, and single- to two-family homes, covering the period from January 1, 2025, to September 30, 2025. The analysis shows that the luxury property market has experienced a substantial rise in values since the pandemic, with a new benchmark median sale price of $2 million now required to be included in the top 100 list. Remarkably, the number of zip codes across the U.S. that surpassed a median sale price of $5 million doubled compared to the previous year, with ten zip codes achieving this feat.
Despite facing intense competition from other states, Massachusetts continues to showcase a robust luxury real estate market across diverse settings. The assortment of high-value areas includes Boston’s urban landscape, Nantucket’s idyllic island vibes, and the suburban allure found in Weston and Wellesley Hills. In contrast, the Northeast, including New York, experienced its weakest performance in a decade, with only 15 entries from New York state appearing on the top 100 list.
The findings of this report highlight a shifting landscape in the luxury real estate market across the United States. While Massachusetts remains a formidable contender for high-end property purchases, states like Connecticut and New Hampshire are increasing their visibility in the luxury segment. As the demand for premium properties continues to grow, potential buyers should pay close attention to these notable markets.
