HomePriceMap tracks 4 counties in Hawaii. The typical (median) county in the state has a home value of $928,556, which is +291.8% above the U.S. national county median of $236,981. Below are all tracked counties in Hawaii, ranked 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 4 of 4 tracked counties in Hawaii; income figures come from the Census Bureau's American Community Survey and home values from Zillow.
Kauai County has the highest median home value in Hawaii at $1,024,959. This is often searched as the "richest" or "wealthiest" county in Hawaii — 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.
Honolulu County has the highest median household income in Hawaii at $106,195. If what you're really after is the "richest" or "wealthiest" county in Hawaii, 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.
Hawaii County has the lowest median home value of the 4 Hawaii counties tracked here, at $576,247. 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 Hawaii has a home value of $928,556, against $236,981 for the median U.S. county — roughly 291.8% higher. Figures come from Zillow's Home Value Index and are refreshed daily on this site.
