The Most Expensive US Zip Code Is a "Billionaire Favorite"

Got a spare $7.5 million? Then you might be able to live in the most expensive U.S. zip code, according to a new report by PropertyShark.

For the fifth year in a row, Atherton, CA’s 94027 landed atop the real estate site’s list, boasting (and emphasis on “boasting”) a median home sale price of $7.475 million, a 7% increase in an area PropertyShark calls a “the billionaire favorite.”

If anything, the pandemic seemed to fuel home prices across the country this year, with the top 10 most expensive zip codes all surpassing the $4 million median sale mark for the first time.

Some key takeaways from the report:

The median home price in 33109 (Miami) jumped 66% year-to-year and is now the fifth priciest zip code in the U.S.
70% of the country’s 100 most expensive zip codes are in California.
No surprise: San Francisco boasted the highest concentration of pricey zip codes.
Surprise: No zip codes in New York City landed in the top 20. The Upper West Side (10069) saw the biggest contraction at a drop of 39%.
States with just one pricey zip code include Florida, Maryland and Arizona. Only 10 states were represented in the list.
The sharpest price gain was 21056 on Maryland’s Gibson Island, which was up 97% Y-o-Y.

PropertyShark calculated median home sale prices across the country over ten months in 2021, taking into account condos, co-ops, and single- and two-family homes. Only zip codes that registered a minimum of three residential transactions were included, and due to the number of ties, the list of 100 most expensive zip codes actually features 127 areas.
