Atlas layers use U.S. Census Bureau ACS 2019-2023 5-Year Estimates. Rent, owner cost, and home value are county medians. Cost score rewards lower rent and lower owner costs, but affordability still depends on income, household size, commute, debt, and personal finances. Use this as decision context, not personalized financial advice.

Housing Costs in Illinois: An Overview

The median rent in Illinois is $837 per month, which is 28% below the national median of $1,163. That is useful statewide context, but rent burden still depends on local income, household size, commute, and the county a household chooses.

Within Illinois, housing costs vary significantly by county. Kendall County has the highest median rent in this dataset at $1,763 per month and a median home value of $298,900. Hardin County has the lowest reported median rent at $342 per month and a median home value of $91,700.

The average home value across Illinois counties is $146,132, 48% lower than the national median of $281,900. Median household income is roughly $68,580, so home values should be read alongside local wages, financing costs, taxes, insurance, and supply.

Before comparing places in Illinois, start with the county-level pattern. Costs can swing dramatically between rural and urban counties. Use the atlas, rankings, and county links below to compare rent, home values, owner costs, and rent burden before opening a specific county profile.
