Saving for a down payment in Illinois is more achievable than in high-cost states like California: a 20% down payment on Illinois's $250,000 median home requires $50,000. However, in Chicago proper with a $380,000 median, that rises to $76,000. Illinois's IHDA (Illinois Housing Development Authority) SmartBuy program offers up to $7,500 in down payment and closing cost assistance as a 0% interest deferred loan, repaid only at sale or refinance. The 1stHomeIllinois program provides a 30-year fixed mortgage plus $7,500 grant (not a loan) for buyers in 34 targeted counties. Unlike California's programs, Illinois's assistance programs are generally more accessible and have less-intense demand competition.

Chicago also has its own CHA and SRB programs for city residents.
What is the minimum down payment for an Illinois home?
Conventional loans require 3-5% down ($9,000-$15,000 on a $300,000 home). FHA requires 3.5% ($10,500). VA and USDA offer 0% down for eligible buyers in rural areas (USDA) or veterans (VA). Putting less than 20% requires PMI — typically $80-$150/month on a $240,000 loan in Illinois.
Is Illinois FHA loan limits the same statewide?
No. FHA loan limits vary by county in Illinois. Cook County, DuPage, Lake, Will, Kane, and McHenry Counties (Chicago MSA) have higher FHA limits of $563,500 for single-family homes (2024). Downstate counties have the standard national baseline. Illinois is not a high-cost FHA area.

1stHomeIllinois provides first-time homebuyers a $7,500 grant (no repayment required) plus a 30-year fixed mortgage at competitive rates. Available in 34 targeted counties. Income limits apply (typically $90,000-$120,000 depending on family size) and the home price must be under $415,000.
Can I use a gift for a down payment in Illinois?
Yes, gift funds from family members are accepted by most lenders for conventional, FHA, and VA loans in Illinois. The gift must be documented with a gift letter stating no repayment is expected. FHA allows the entire down payment to be gifted; conventional loans may require some borrower funds depending on the loan-to-value ratio.
