The Most Expensive US Counties to Buy a Home
Published:
Last Updated:
The COVID-19 pandemic has ushered in an unprecedented surge in demand for homes in the United States. Inventory is at a record low, as is the average time homes are on the market. Meanwhile, both home prices and the share of homes selling above asking price have reached record highs.
Of course, in some parts of the country, exorbitant home prices are nothing new. Even before the pandemic, there were counties across the country where most homes had an estimated value of about half a million dollars and higher. Meanwhile, the median home value nationwide is $217,500.
Using data on median home value from the U.S. Census Bureau, 24/7 Wall St. identified the most expensive counties to buy a home in the United States. Our analysis includes county and county equivalents, such as independent cities. Counties with less than 1,000 housing units were not considered. Most of the counties on this list are in the Western United States, including 18 in California alone.
Home values in a given area are often a reflection of what residents can afford. And not surprisingly, with only one exception, the median annual household income exceeds the $62,843 national median in every county on this list. Here is a look at the best counties to live in.
Still, despite the higher incomes, home values in the counties on this list are high enough that buyers are more likely than average to have to rely on a mortgage. In most counties on this list, the share of homeowners who are financing with a mortgage is above the 62.7% share of homeowners with a mortgage nationwide. High home prices also appear to make homeownership prohibitively expensive for many living in these counties, as most counties on this list have a lower homeownership rate than the 64.0% rate nationwide. Here is a look at the counties where the most people have debt in collections.

Methodology
To determine the most expensive counties to buy a home in the nation, 24/7 Wall St. reviewed five-year estimates of median owner-occupied home values from the U.S. Census Bureau’s 2019 American Community Survey.
Of the 3,220 counties or county equivalents, 3,142 had boundaries that fell within one of the 50 states or the District of Columbia.
Counties were excluded if owner-occupied median home values were not available in the 2019 ACS, if there were fewer than 1,000 housing units, or if the sampling error associated with a county’s data was deemed too high.
The sampling error was defined as too high if the coefficient of variation — a statistical assessment of how reliable an estimate is — for a county’s owner-occupied median home value was above 15% and greater than two standard deviations above the mean CV for all counties’ owner-occupied median home values. We similarly excluded counties that had a sampling error too high for their population, using the same definition.
The remaining 3,044 places were ranked based on their owner-occupied median home values. To break ties, we used median monthly housing costs with a mortgage.
Additional information on median monthly housing costs with a mortgage, the share of owner-occupied housing units that have a mortgage, rates of homeownership, and median household income are also five-year estimates from the 2019 ACS.
