California Is Home to 91 of the 100 Most Expensive Zip Codes in the U.S. — Here's No. 1 (Video)

California is well-known for its stunning coastlines, gorgeous redwood forests, lavish Hollywood scene, and over-the-top celebrity homes. It's also known for one more thing: being expensive as hell.

According to the new rankings by the real estate website, PropertyShark, California is home to 91 of the top 100 most expensive zip codes in the nation. To come up with the ranking, PropertyShark explained, the website analyzed year-to-date residential sales and determined the median sale price of each zip code.

The website explained in a blog post, this is the most accurate way to reflect the data as it ensures "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."

Once calculated, the team found that California was not only home to 91 of the top 100, it was also home to six of the top 10. And coming in at number one is the town of Atherton, located in San Mateo County, with a median home sale price of $7,050,000.

Sagaponack, located in New York's Long Island, came in second place. However, the website noted the town barely held onto its spot after suffering a "significant 22 percent price contraction from 2018's $5,500,000."

Santa Monica, California came in third place followed closely by Beverly Hills. Rounding out the top five is the town of Gibson Island in Maryland.

Though California dominated the list, New York state wasn't far behind. It took home 18 of the top 100 most expensive zip codes, including a first-time appearance by Brooklyn with both the Carroll Gardens and Red Hook zip codes coming in with a median home price of $1.45 million.
