County Median Home Prices and Monthly Mortgage Payment
Median Home Values
Applying the House Price Index growth from FHFA to the latest housing data from the American Community Survey (ACS), we calculated a median home value for 3,119 counties and county-equivalents in the United States. Home values represent the value of all homes instead of home sales.
Nationwide, we estimated that the price of a typical home was $235,000 in the third quarter of 2018. Based on our estimates, 87 percent of counties had a lower median home value than the national level.
Here is the list of the counties with the highest median home values:
San Francisco County, CA: $1,272,170
San Mateo County, CA: $1,252,580
Marin County, CA: $1,168,350
Santa Clara County, CA: $1,112,010
Nantucket County, MA: $1,046,930
Mortgage Monthly Payment
We also calculated the monthly payment by county based on the following mortgage rates: 4.5 percent, 5.0 percent and 5.5 percent.
 The U.S. median home value matches the county prices calculations. For comparisons purposes, the calculated median home value reflects all homes while NAR’s U.S. median price represents home sales. Thus, the calculated price ($213,099) is expected to be lower than NAR’s home value ($253,600 in Q2 2017). Please see Methodology for more details.
