Home Program The @HomeIllinois mortgage program for first time home buyers. This is a 30 year, fixed rate mortgage that requires Illinois borrowers to pay 1 percent or $1,000 of the purchase price, whichever is greater. Buyers must meet income and purchase price limits, and must have a credit score of at least 640. They must live in the home as a primary residence and must complete a housing counseling program that is offered in both online and in person options. The program also offers other types of help to buyers, including: $5,000 in Illinois down payment or closing cost assistance (payment terms are 0 percent for 10 years, and Illinois borrowers who meet certain income limits do not have to pay back the loan), a federal tax credit certificate, lender paid mortgage insurance, a choice of loan type that includes FHA, VA, USDA or conventional.
