It’s been a trying year for many industries, and while real estate is booming in some cities, it has taken its hits in others. PropertyShark has compiled 2020 data and found the top 10 priciest zip codes in the United States this year, using the median home sales prices as the marker.
The biggest change is that no zip codes from New York City appear, whereas last year, two zip codes from the Big Apple made the top 10 list. A Boston zip code also lost its spot. However, most of the swanky areas that did rank won’t come as a surprise.

For everything people say about the priciness of the East Coast, one thing is clear in 2020: The West Coast is largely more expensive for buyers. If looking at the 10 most expensive areas doesn’t prove this enough, PropertyShark found the country’s 121 priciest zip codes as well, of which 87 were in California compared to 20 in New York.
Just missing the very top of the list, NYC’s Downtown 10007 zip code nabbed spot #11 after suffering a 15% decrease in closing prices from last year. Perhaps 2021 will bring New York City back into the top 10, but for now, California is firmly holding the majority there with the Hamptons keeping up as well.
