Boone County, IL Property Records & Statistics
Boone County has a median rent of $1,172, far above the Illinois median of $762 and the national figure of $840.25. The median home value is $190,400, higher than the state's $116,950 and the national $173,750. Renter-occupied housing is only 5.44% of homes, compared with 18.61% statewide and 21.81% nationally, so the county is overwhelmingly owner-occupied and rental options are limited.
Property taxes are a major factor. The county's median property tax rate of 2.43% is above the state rate of 1.8% and more than three times the national rate of 0.74%, making ownership costly relative to home value.
Median household income is $95,938, well above the Illinois median of $65,699.50 and the national $65,108. The unemployment rate of 10.97%, however, is far higher than the state's 2.92% and the nation's 2.87%.
The figures describe a high-cost, high-income county with scarce rental housing and heavy property taxes, where strong earnings sit alongside unusually high unemployment.
