America’s Most Expensive ZIP Codes Of 2023

If you’re contemplating where to buy a house and settle in, you shouldn’t only take into consideration the city and state. Property taxes and school districts are more important factors in relation to home ownership than city-level. We analyzed Zillow’s home price index for August 2023 to determine the 100 most expensive zip codes in America. As part of our analysis, we took into consideration the latest monthly home values Zillow has — August 2023 — as well as the average of 12 months of median home values from September 2022 to August 2023, in order to gain a fuller picture.
