Today's Illinois rates by loan type
Estimates for Illinois based on the current national 30-year average of 6.85% plus the state's typical spread (+1 bps). Live national rate sourced daily from Freddie Mac PMMS via our rate feed. Your actual quote will depend on your credit, down payment, and lender.
What drives Illinois mortgage rates
National rates set the floor — Freddie Mac's weekly PMMS average is the benchmark almost every Illinois lender starts from. But IL typically prices about 1 basis points above that national average because of three local dynamics: the mix of loan types written in the state, lender density and competition, and how expensive the state is to close in.
Loan mix. Conventional dominant; FHA share strong in Cook County. The mix matters because FHA, VA, and USDA loans price differently than conventional — states with heavier government-loan share tend to show tighter buyer rates but higher fees.
Median loan size. The typical Illinois loan is around $255,000 on a $285,000 home. That size sits well inside conforming loan limits, so most IL buyers get standard agency pricing.
Refi activity. Refi share is small — most legacy loans are already sub-5%.
