The median home value in Illinois is $250,000. Chicago and suburbs have seen moderate appreciation — less than coastal markets, partly dampened by property tax concerns deterring buyers. Suburban markets like Naperville remain strong.
The conforming loan limit in Illinois is $726,200. Most Illinois counties are at the standard conforming limit. No counties currently qualify for high-cost treatment. Loans above this threshold are considered jumbo loans and typically carry stricter qualification requirements and slightly higher rates.
Beyond your mortgage payment, budget for Illinois's property taxes: the effective rate is 2.07%, meaning a home at the median value generates about $5,765/year in taxes. This is a real cost that lenders include in your debt-to-income (DTI) calculation.
Buyers typically pay around $3,900 in closing costs in Illinois. Illinois charges a transfer tax of $0.50/$500 of value statewide, plus a City of Chicago transfer tax of $5.25/$500 which is one of the highest city-level rates nationally. Factor this into your upfront cash requirement alongside your down payment.
