The Garden State has expanded its presence on the list of America’s most expensive zip codes with a few familiar names and perhaps a few surprises.
Property Shark has published its annual list of the most expensive zip codes in the United States, with Atherton, California’s $10.7 million average sale price topping the rankings. The study examined sales nationwide that were finalized over the 2026 calendar year, and a price enclave near New York City was again New Jersey’s highest entry.
The Bergen County borough of Alpine topped the state again, ticking up to a $4.38 million average home sale price and coming in at #15 nationally. Seven New Jersey zip codes made the top 100, with six of the towns reaching record-high prices.
In terms of New Jersey, Alpine was followed by 08247 in Stone Harbor. The shore town came in at $3.13 million, its first-ever median sale price above $3 million.
Nearby Avalon also made the list, with an average sale price of $2.8 million. Deal’s 07723 was the only New Jersey town on the list whose prices contracted, dropping nearly $1 million year-on-year to $2.65 million but still good enough for 64th nationally.
Other entries include the New York City suburb of Short Hills, which had a $2.45 million average sale price. Monmouth County’s Rumson, another regular in the top 100, came in at $2.41 million.
A new entry in the top 100, Cape May Point’s 08212, ranked 89th with a $2.35 million sale price. Property Shark’s rankings noted that New Jersey’s presence has increased steadily since the pandemic, driven by Cape May County—an area outside the New York metro, traditionally the state’s most expensive area.
New Jersey has also contributed to the East Coast’s growing presence on the list, ranking a record seven locations this year to tie with Connecticut.
The top 10 included a few towns on Long Island in New York that regularly rank high again. #2 Sagaponack’s 11962 zip code had a $7.35 million average sale price, with Bridgehampton’s $6.15 million average sale price ranking fourth in the country.
Coming in at #7 was 11976 in Water Mill with an average sale price of $5.75 million. Other notable entries in the tri-state area include New York City zip code 10013 at #26 with a $3.85 million sale price and perennial entry Greenwich, Connecticut’s 06870 at $2.82 million.
Overall, 11 of the 15 ranked states reached record high prices in Property Shark’s rankings, including New Jersey.
