Towns in California and New York dominated the top spots on the most recent America’s Most Expensive ZIP Codes rankings from business magazine Forbes and housing market data provider Altos Research. To find the priciest enclaves, Altos analyzed listing prices for single-family homes and condos in in 29,500 ZIP codes across the U.S., which covers 95% of the population. Altos then calculated a median, rolling average for a 90-day period ending Oct. 9, 2015, and the 500 most expensive ZIP codes made it to the list.

Just across the river from some of New York’s priciest ZIP codes is Alpine, New Jersey – ZIP code 07620 – which ranked 12th in the country and first in the Garden State. Here, the median home price is more than $4.8 million. At that price, buyers can expect spacious homes with six-plus bedrooms and baths, as well as lavish master suites, gyms, media rooms, several fireplaces, multi-car garages and outdoor pools.   

What Houses Cost in Alpine

In Alpine, $4.8 million is the median price, but you could easily spend much more. The priciest home on the Alpine market today is listed at $48.8 million – 10 times the median home price. The home, which is located just eight miles from New York City, is a gated six-acre estate of 30,000 square feet, featuring 12 bedrooms, 19 baths, a ballroom, a movie theater, an indoor basketball court, a 4,000-bottle wine cellar, a fitness center, multiple bars for entertaining, and an outdoor tennis court and pool.

With a median home price around $4.8 million – and homes on the market well above that – you’d expect to find some ultra-wealthy residents. Indeed, the median household income here is $170,000, and some of the town’s notable residents (who were born in Alpine, reside there now or have resided there) include billionaire Glenview Capital Management founder Larry Robbins, comedian/actor Tracy Morgan, rap artist Sean “Diddy” Combs and singer Britney Spears.

The Bottom Line

Some of New Jersey’s most expensive ZIP codes, including Alpine, are considered suburbs of New York City, but you’ll typically get a lot more house if you stay on the New Jersey side of the Hudson River. Plus, at $1 million-plus in any of these expensive suburbs, you’re likely to find homes with privacy, well-designed landscaping and relaxing outdoor spaces that will allow you to take a break from the city.
