Tax and insurance are collected alongside the loan but are not part of it, so they are excluded here.
What Illinois actually costs a homeowner
Second-highest rate in the country, driven by heavy reliance on property tax for school funding, especially in Cook County.
On the state median home value of $239,100, the property tax bill works out at roughly $4,949 a year, or $412 a month before anything else. That is above the national effective rate of 0.86% — 2.4 times the US average.
Insurance is the other half of the escrow payment. At about $2,300 a year, Illinois sits below the national average of roughly $2,400. Together, tax and insurance add around $604 a month to the loan payment on a median-priced home here.
Why your bill will differ
The figure above is a state average, and property tax is set locally. Two houses of the same value in different counties of Illinois can carry bills that differ by thousands. Check your county assessor before treating any estimate as final, and check whether a homestead exemption applies to you — in most states it does, and in several it is substantial.
A high property tax state
Illinois sits in the top tier nationally, 2nd of 51 by effective rate. At 2.07% the tax bill is a genuine constraint on what you can borrow: lenders count it in your debt-to-income ratio, so a $4,949 annual bill reduces your purchasing power by roughly $63,453 of loan at current rates. Buyers moving here from a low-tax state routinely find they qualify for less house than they expected.
Tax and insurance are close to balanced
About $4,949 in tax against $2,300 in insurance, so neither dominates the escrow payment. Together they add roughly $604 a month before any principal or interest — the part of a housing budget that does not fall as you pay the loan down.
Stepping up from the median
At $360,000 — about half again the Illinois median — the annual tax becomes $7,452 and the escrow portion of the payment rises to roughly $813 a month. With 20% down at 6.5% over thirty years, the all-in payment is about $2,633.
