(NEXSTAR) – U.S. home prices took off in 2021 as buyers competed for a limited number of houses, driving prices skyward in the nation’s most expensive ZIP codes, according to real estate data provider Property Shark.

The report found that, for the first time ever, the top 10 priciest ZIP codes all surpassed $4.4 million when it came to the median home sale price.

The list included ZIP codes from 10 states and California dominated the list of the top 100, taking 70 percent of spots.

Property Shark found that twice as many ZIP codes in 2021 had a median home sale price over $3 million than in 2020.

The San Francisco Bay Area alone has 47 of the costliest ZIP codes on the list, including the most expensive, Atherton, in San Mateo County (94027). It’s Atherton’s fifth year running at the top of the list, with the average sale price of $7.5 million.

Outside of the Golden State, Boston’s 02199 landed in second place. Miami’s 33109 wound up in fifth place thanks to a 66% boost from last year’s median sale price.
