Amagansett Leads U.S. in Home Price Increases

Atherton, California, may reign as the nation’s most expensive zip code, but no enclave in America saw prices jump as dramatically this year as Amagansett.

The median listing price in the East Hampton hamlet has climbed 39 percent year-over-year to $4.3 million, according to RealtyHop’s third annual report of the most expensive zip codes in the U.S., based on an analysis of 3.6 million residential listings from the start of the year through mid-October.

While Atherton claimed the throne for the third straight year, the Hamptons were well represented among the top 100, with Sagaponack taking second place. A median-priced home in the Southampton Town village asks slightly below $7 million, the report found, beating out Beverly Hills, California’s famed 90210 to move up one spot from last year.

The median listing price in Sagaponack was up 16.3 percent year-over-year, according to Behind the Hedges.

The Hamptons weren’t done there. Water Mill clocked in sixth in the ranking, with a median listing price of $5.5 million. Bridgehampton also cracked the top 10 — 10th, specifically — with a median listing price of $4.4 million.

Zoom out further and the Hamptons appear at every turn. Other locales ranked in the top 100 include Amagansett (13th) Quogue (16th), Wainscott (36th), Noyack (46th), first-time entry Remsenburg (61st), Montauk (70th), Northwest Harbor (88th) and another debut, Westhampton Beach (92nd).

Though west of the Hamptons, Mill Neck in Nassau County recorded the second-highest annual gain, with the median listing price of $4 million, up 36 percent compared to last year.

The 100 priciest zip codes were concentrated in just 13 states, and more than half were in California. New York claimed 22 of the remaining 41 zip codes, many of which were either in the Hamptons or New York City. New Jersey and Massachusetts each claimed three.

Though home price growth is slowing as mortgage rates rise, most markets are still reporting annual gains, and the most expensive locales are no exception. The report cited 60 zip codes with a median listing price of at least $2.5 million, 13 more than a year ago. Additionally, the median listing price from the 100 most expensive zip codes combined was up 11 percent compared to the same period last year.
