Read on to find out the most expensive ZIP codes in Montana in 2024, relying on data from Zillow’s home value index and the Census Bureau.
The Most Expensive ZIP Codes in Montana
Using data from Zillow’s home value index, we analyzed thousands of ZIP codes throughout the United States. For Montana, we’re analyzing the 233 ZIP codes that Zillow has data on in its index. Breaking down wealth by ZIP codes is revealing because, as a geographic unit, they might, for example, show you an insanely rich pocket of an otherwise medium-income or lower-income town. ZIP codes are there for purposes of the mail, so they don’t always cleanly align with city boundaries.
As part of our analysis, we took into consideration the latest monthly home values Zillow has — December 2024 — as well as the average of 12 months of median home values from January 2024 to December 2024, in order to gain a better picture.
Below are the 25 most expensive ZIP codes in Montana.
