Illinois's mortgage market has its own distinct rules — from closing customs to transfer tax structure to the specific down payment programs available through the state's housing finance agency. This guide covers what's genuinely different about buying in Illinois, not just the generic national mortgage process.

How Illinois Closings Work

While not universally mandated, Illinois attorney-review periods are standard practice in most contracts (typically 5 business days after acceptance), and the majority of Chicago-area transactions use attorneys for both contract review and closing.

Transfer tax: $1.50 per $1,000 state tax plus $0.50-$3.00 per $1,000 county tax plus Chicago's own $5.25 per $1,000 (increased for high-value sales via 2023 referendum) — creates one of the most complex multi-layered transfer tax stacks in the country.

The Illinois Property Tax Quirk You Should Know

Illinois has the second-highest effective property tax rate in the nation, driven primarily by Cook County and the collar counties' reliance on property tax to fund pension obligations — this is a structural, long-term feature of the market rather than a temporary spike, so buyers should budget for continued above-average increases.
