Two South Jersey Zip Codes Rank Among NJ’s Priciest

Two South Jersey zip codes rank among the top five most expensive zip codes in the state and in the top 75 nationally when it comes to home sale prices in 2025, according to an annual survey by real estate data firm Property Shark.

Stone Harbor and Avalon, two coastal towns on Seven Mile Island in Cape May County, were both in the survey's top 100 in 2024.

What does the Median Sales Price Mean?

The median sales price is the midpoint of a list of all sales prices, where half of the properties sold for more and half sold for less. 

It is different than the average, which can be skewed by a few very high or low-priced sales; the median provides a more accurate representation of a "typical" sale price for a zip code and a timeframe. 

To determine the most expensive zip codes in the U.S. in 2025, Property Shark says they looked at registered residential transactions closed between January 1 and September 30, 2025.

They took into account condo, co-op, and single- and two-family home sales, but excluded all multi-parcel deals.
