Property taxes follow the same pattern, with a median rate of 1.59% against 1.11% in Ohio and 0.74% nationally. Buyers here face high prices and a heavier tax rate than most of the state and the country.
Household income helps explain the difference. The county's median of $123,923.50 is nearly double Ohio's $66,091.50 and the national $65,108. Employment is strong as well, with an unemployment rate of 1.98% compared with 2.41% in the state and 2.87% nationally.
