HUDSON VALLEY, NY — There is no question that real estate in the Hudson Valley demands a steep price, but a just-released study found three Hudson Valley ZIP codes are among some of the most expensive in the entire country.

Real Estate market-watcher PropertyShark calculated median sale prices based on closed home sales, to identify the 100 most expensive ZIP codes in 2026. Three Westchester County communities were listed as among the very highest priced, including one that is making its debut on the list this year.

For the 11th consecutive year, Rye's 10580 ZIP code returned as Westchester County's priciest ZIP code. The 10580 ZIP code ranked 69 on the list, with a listed median sale price of $2.58 million. This is a rise up the list from 2025, when Rye came in at number 92 with a median sale price of $2.16 million.

For the first time ever, Waccabuc's 10597 made the list, coming in at number 76, with a median sale price of $2.45 million.

While the 10577 ZIP code in Purchase did not make the list in 2025 or 2024, it was back on the list for 2026, ranking at number 83, with a listed median sale price of $2.42 million.

In order to determine the most expensive ZIP codes, PropertyShark said that it considered all home transactions that were closed between January 1 and September 30.

Due to multiple ties, 122 ZIP codes made this year's list. California claimed 57 percent of the most expensive ZIP codes in the country, the most of any state. New York had "one of its best post-pandemic years," with 20 ZIP codes making the list, with half from Suffolk County. Westchester County had a record three ZIP codes on the list this year, which equaled New York City's number.

Atherton, California's 94027 ZIP code was the most expensive in the U.S. in 2026, with a median sale price of $10.73 million, reclaiming the spot from 2025's leader, ZIP code 33109 on Florida's Fisher Island. Sagaponack, NY ranked number 2, with a $7.35 million median sale price.
