Illinois Mortgage Calculator
Work out what a home in Illinois really costs per month. The calculator below starts from the state's typical home price of $270,000 and its 2.08% effective property-tax rate — higher than the 1.1% national average — which works out to about $5,616 a year in property tax on a median home. Average local homeowners insurance ($2,643/year) is included too, so the estimate is a realistic all-in figure of around $2,053/month on a standard 30-year purchase rather than a bare principal-and-interest number. Swap in your own price, rate and down payment to refine it, and see below for how Illinois compares with the rest of the country.

Property taxes in Illinois
Illinois's effective property-tax rate is about 2.08% of a home's value each year — higher than the U.S. average of 1.1%. On the state's median home price of $270,000, that works out to roughly $5,616/year ($468/month) added to your payment.
Good to know: Illinois carries the second-highest effective property-tax rate in the country, driven largely by local school funding; Cook County assesses property differently than the rest of the state.

Homeowners insurance in Illinois
Lenders require homeowners insurance, and in Illinois it averages about $2,643/year ($220/month) for a policy with $300,000 in dwelling coverage — 4% above the U.S. average of $2,543. Premiums run high here, so it's worth comparing several insurers and asking about wind, hail or flood deductibles that may apply separately. The calculator above already includes this figure in the monthly estimate — replace it with a real quote when you have one.
Buying a home in Illinois
Start from the sticker price: Illinois's median home runs $270,000, about 36% more affordable than the national median of $420,000. Financed with 20% down over 30 years at roughly 6.5%, principal and interest alone is near $1,365/month; layering on property tax ($468/month at the state's 2.08% rate) and average insurance ($220/month) lifts the realistic monthly cost to about $2,053. HOA dues and PMI (below 20% down) would come on top. Since the property-tax rate sits above the U.S. average, that line item matters more in Illinois than in most states — try your own numbers in the calculator to see the effect.
