Buying a home in Illinois
Lenders qualify Illinois buyers on gross income, but the budget that actually pays the mortgage is net of the state's flat 4.95% income tax — a few percentage points of headroom that a pre-approval letter quietly assumes you have. Property tax adds a second, permanent layer at roughly 1.97% of assessed value per year.
A buyer earning $100,000 with $600 monthly recurring debt, 20% down, and a 6.5% 30-year fixed mortgage can typically afford a home up to about $333,816.05 in Illinois, with an estimated monthly housing cost around $2,333.33. The 2026 median single-family home price in Illinois is around $340,000.
The 1.97% property tax used here is a statewide effective average — actual bills are set at the county and city level and can differ substantially within Illinois. Verify with Illinois Department of Revenue (https://tax.illinois.gov/research/publications/bulletins/fy-2026-15.html) and the county assessor before setting a price ceiling.

What is the property tax rate in Illinois?
Illinois's effective property tax rate is approximately 1.97% of assessed home value annually. That is on the higher end nationally — only New Jersey (~2.26%) and Connecticut (~1.98%) are higher. On a $340,000 home, expect roughly $6,698 per year in property tax.
What is the median home price in Illinois?
The 2026 median single-family home price in Illinois is around $340,000. With 20% down that means a down payment near $68,000 and a financed amount of about $272,000. Prices vary widely by metro — coastal and urban areas typically exceed the state median by 30%–60%.
Is Illinois good for first-time homebuyers?
Illinois state income tax reduces take-home pay, which lenders factor into debt-to-income ratios. Property tax at 1.97% is a meaningful monthly cost to budget. Illinois first-time buyers may qualify for state-administered down-payment-assistance programs through the state housing finance agency.
What's the 28/36 rule and how does it apply in Illinois?
Lenders typically cap front-end DTI (housing payment / gross monthly income) at 28% and back-end DTI (housing + all debt / gross monthly income) at 36%. In high-property-tax states like Illinois (~1.97% property tax), the front-end ratio binds sooner because property tax and insurance can push monthly housing 25%–35% above pure principal & interest. Use the comfortable, stretch, and maximum ranges above to gauge how aggressive your budget is.
Can I afford more house in Illinois or Indiana?
On the same $100,000 income, 20% down, 6.5% rate, good credit profile, the estimated max home price is $333,816.05 in Illinois vs $390,633.01 in Indiana. Indiana allows about $56,816.96 more purchasing power — driven mainly by differences in state income tax (affecting take-home) and property tax rates.
