For this article, we wanted to breakdown the most expensive ZIP codes in Massachusetts. Vacation spots in Nantucket, Martha’s Vineyard, Cape Code, and the Berkshires not surprisingly are home to many of the most expensive ZIP codes. But so does the Boston metro area. Read on to find out the most expensive ZIP codes in Massachusetts in 2024, based on the latest data from Zillow’s home value index.

The Most Expensive ZIP Codes in Massachusetts

Harnessing data from Zillow’s home value index, as well as the Census Bureau’s 2023 American Community Survey, we analyzed thousands of ZIP codes across the U.S. as part of a general survey. From there, we focused our attention on Massachusetts. The Zillow home value index tracks (as of September 2024) the home values of 484 ZIP codes in Massachusetts. As part of our analysis, we took into consideration the latest monthly home values Zillow has — September 2024 — as well as the average of 12 months of median home values from October 2023 to September 2024. While home values have grown immensely across America since the pandemic-induced buying frenzy, home value appreciation in Massachusetts stands out. One of the most expensive ZIP codes in Massachusetts witnessed home values surge by 84.8% over the last five years.

Some very clear patterns emerge from this analysis. The majority of the most expensive ZIP codes in Massachusetts are contained within just a couple of metropolitan areas. Below are the 25 most expensive ZIP codes in Massachusetts.
