This shows county median home values divided by county median household income, both for 2023.

For example a score of "5" means the median home price in that county is 5 times the median household income in that county.

Generally, a score under 4 is considered affordable, 4-6 is pushing it, and over 6 is unaffordable for the median income.

There are of course other factors to consider such as property tax, down payment amount, assistance programs, etc. Property tax often varies at the city/township level so is impossible to accurately show.

Median Household Income Data is from US Census Bureau.

Median Home Value from National Association of Realtors, and Zillow/Redfin .
