Alpine Remains New Jersey's Most Expensive Zip Code, Report Says

Seven New Jersey zip codes appeared on the list of the most expensive areas in the United States this year, according to a report from Property Shark.

The annual study, which examined sales finalized over the 2026 calendar year, shows the state’s presence in the high-end market is expanding. While California’s Atherton topped the national rankings with an average sale price of $10.7 million, multiple New Jersey towns reached record-high prices.

Alpine remains the state’s most expensive enclave, Jersey Digs reported. The Bergen County borough secured the #15 spot nationally, with its average home sale price climbing to $4.38 million.

This surge in property values reflects rising costs across the East Coast. New Jersey tied with Connecticut for the highest number of locations on the list, with both states contributing seven zip codes to the top 100 rankings.

A notable driver of this geographic expansion is Cape May County. Traditionally, the state’s most expensive real estate has been concentrated near the New York metropolitan area, but the pandemic era has pushed demand further south. This shift is evidenced by the inclusion of several shore towns in the top 100 rankings.

Stone Harbor (08247) emerged as the state’s second most expensive area, posting an average sale price of $3.13 million. This marks the first time the shore town has surpassed a $3 million median sale price. Nearby Avalon also made the list, recording an average sale price of $2.8 million.

The coastal market continues to attract high-net-worth buyers, even as certain established luxury markets show signs of cooling. For example, Deal (07723) was the only New Jersey town on the list to see a contraction in prices. The area’s average sale price dropped by nearly $1 million year-on-year to $2.65 million, though it still maintained the 64th position nationally.

The following table compares the primary New Jersey entries identified in the Property Shark study:

Zip Code	Location	Average Sale Price	National Rank
08247	Stone Harbor	$3.13 million	Not specified
07723	Deal	$2.65 million	#64
08212	Cape May Point	$2.35 million	#89

The high-end real estate landscape in the tri-state area remains dominated by a mix of established suburbs and coastal retreats. Long Island, New York, continues to hold several high-ranking positions. Sagaponack’s 11962 zip code ranked second nationally with a $7.35 million average sale price, followed by Bridgehampton at #4 with $6.15 million. Water Mill (11976) also appeared at #7 with an average of $5.75 million.

In the urban core, New York City’s 10013 zip code ranked 26th nationally with an average sale price of $3.85 million. Meanwhile, Greenwich, Connecticut, remains a perennial fixture on these lists, with its 06870 zip code posting an average price of $2.82 million.

The data suggests a period of intense valuation growth across the country. Out of the 15 states ranked in the Property Shark study, 11 reached record-high average prices for their most expensive zip codes.

While these figures highlight immense wealth concentration, they also show luxury inventory is tightening. The expansion of high-priced enclaves into areas like Cape May County suggests that the traditional boundaries of the New York metro area’s economic influence are stretching further into the Garden State.

The most recent entry into the top 100 for the state was Cape May Point, which ranked 89th with an average sale price of $2.35 million.
