The priciest ZIP codes in the U.S. are coastal, wealthy enclaves or luxury vacation destinations where homes typically cost more than $4 million, according to a recent RealtyHop report. Atherton, California, near Stanford University, tops the list as the wealthiest ZIP code in the U.S., with a median home price of $7.75 million, driven by large estates owned by Silicon Valley executives, entertainers and athletes like NBA star Stephen Curry. Expensive real estate is also prominent in other cities in California, as well as Miami Beach and the Hamptons, where homes routinely sell for millions. Mountain towns such as Aspen, Colorado, and Big Sky, Montana, attract buyers seeking exclusivity and natural beauty. The median price for the most expensive ZIP code in each state, calculated across all states, is $1.55 million, according to the study. Mississippi stands out as the most affordable state, with median-priced homes in Madison (39110) going for $465,000. To compile the rankings, RealtyHop looked at median listing prices for all types of homes in all ZIP codes in the U.S. between Jan. 1, 2024, and Oct. 15, 2024. Any listings with invalid ZIP codes or single-building ZIP codes were excluded from the study. RealtyHop then ranked the three priciest ZIP codes in each state and district. Here are the top three for each state, listed in alphabetical order.
