HomePriceMap tracks 30 counties in New Mexico. The typical (median) county in the state has a home value of $233,243, which is -1.6% below the U.S. national county median of $236,981. Below are the most expensive and most affordable counties in New Mexico by current median home value.
This ranks each county by its median home value divided by its median household income — how many years of a typical local income it would take to buy a typical local home. Housing researchers generally treat about 3× income as manageable and 5× or more as severely stretched. Coverage is 29 of 30 tracked counties in New Mexico; income figures come from the Census Bureau's American Community Survey and home values from Zillow.
Violent crime rates below are a population-weighted average of each county's reporting cities from the FBI's Uniform Crime Reporting Program, covering 18 of 30 tracked counties in New Mexico. Counties with no FBI-reporting city aren't shown.
Los Alamos County has the highest median home value in New Mexico at $593,582. This is often searched as the "richest" or "wealthiest" county in New Mexico — though it's worth being precise about what's being measured here: median home value reflects property prices, not household income or net worth. The two usually correlate, but a county can have expensive homes without having the highest-earning residents, particularly in areas with a lot of vacation or second homes.
Los Alamos County has the highest median household income in New Mexico at $147,139. If what you're really after is the "richest" or "wealthiest" county in New Mexico, this is the closer answer — income measures what households actually earn each year, while home values measure what property costs. Neither is quite the same as wealth, which would also account for savings, investments and property people already own outright.
Hidalgo County has the lowest median home value of the 30 New Mexico counties tracked here, at $95,661. Keep in mind that low home prices often reflect limited local job markets, distance from major metro areas, or shrinking population — affordability alone doesn't tell you whether somewhere is a good fit.
The typical (median) county in New Mexico has a home value of $233,243, against $236,981 for the median U.S. county — roughly 1.6% lower. Figures come from Zillow's Home Value Index and are refreshed daily on this site.
