The Census Bureau's ACS 2025 medians put Illinois's typical bill at $5,655 on a $294,400 home — an effective 1.92%. Effective rates blend every local levy into one comparable number; your parcel's assessed value and local rates set the real bill.

The CFPB puts typical buyer closing costs at 2–5% of the loan (origination, appraisal, title, prepaid escrows). The default here is 3% and the field is yours to change — no official schedule exists, and this page will not pretend one does. Illinois transfer/recording charges sit inside that range for most purchases.

Property tax. At 1.92%, Illinois adds $471 a month on the median home — in the highest-tax states that rivals a full percentage point of interest rate.
No — it is the state's median effective rate applied to your price. Assessments, exemptions (homestead and others) and local rates move real bills both ways; the county assessor's figure governs.
Below 20% down, lenders usually add private mortgage insurance (roughly 0.3–1.5% of the loan per year) until you reach ~20% equity. It is not in the default total — add it to the insurance line mentally if it applies.
