- Get your credit reports, dispute what is wrong, and only then start shopping.
- Model the payment on the calculator before a lender models it for you.

- Make sure the lender appears in the Illinois regulator's licence list.
- Read the disclosure for an origination fee and any prepayment penalty before signing.
- Check that the monthly payment fits your budget next to your existing obligations.
