MONMOUTH COUNTY, NJ — Two Monmouth County zip codes are among the priciest in the U.S., according to the 10th edition of the annual PropertyShark report, which is based on closed-sale data.

This year, $2 million was the minimum median sales price to make the top 100 of the most expensive zip codes. Five years ago, fewer than 50 of the most expensive zip codes had reached that mark.

Another sign of post-pandemic price acceleration was that 10 zip codes surpassed $5 million, according to Property Shark.
