Chester County has the most expensive housing market in Pennsylvania, according to a recently published report by 24/7 Wall Street, writes Samuel Stebbins for USA Today.

Typically, a home nationwide costs close to a quarter of a million dollars, but there is at least one county in nearly every state where housing prices are higher.

To find which county has the most expensive housing market in each state, 24/7 Wall Street reviewed median home prices in the 3,119 county and county-equivalents using data from the National Association of Realtors for the third quarter of 2018.

Meanwhile, data from the U.S. Census Bureau’s 2017 American Community Survey considered median household incomes and median monthly housing costs for mortgage holders, along with the share of occupied homes worth more than a million dollars and year of construction.

Chester County was tops in Pennsylvania with a median home value of $384,436.

The state’s most affluent county had 2.9 percent of homes valued at $1 million or more in 2017, and 18.6 percent of housing units constructed in 2000 or later. It also has a median household income of $92,417 and median monthly housing costs with mortgage of $2,216.
