Which ZIP Code Is the Most Expensive in the Nation?

No post code envy here: Buying a house in Atherton, Calif., will set you back an average of $7 million. PropertyShark ranked the most expensive U.S. ZIP codes by average sale prices, and California captured 91 slots out of the top 100 despite consistently suffering devastating fires across the state in recent years. Find out if your ZIP code made the ranking.

PropertyShark has been tracking the most expensive U.S. zip codes for years, analyzing nationwide residential transactions to provide the most accurate snapshot of the nation’s most expensive markets. In order to create the most accurate benchmark, year-to-date residential sales were analyzed to determine the median sale price of each zip code. Due to a large number of ties in medians, 125 zip codes made the list as the 100 most expensive.

Calculating medians based on sale prices rather than asking prices more accurately reflects the reality on the ground in the country’s most cutthroat markets – where low supply pairs with high demand, often pushing sale prices above the initial asking figures. It also ensures that ultra-luxury properties – which generally spend extended periods of time on the market and often sell with notable price cuts – don’t skew the numbers away from what the market is actually willing to pay.
