Even with poor credit getting a home loan is still possible. A lender will consider you to be a risky borrower and to compensate for this they will charge you a higher interest rate, and expect a higher down payment usually 20%-50%. The worse your credit history is, the more you can expect to pay.
*All rates are subject to approval with 80% loan to value, 740 fico and Fannie Mae, Freddie Mac and FHA loan limits apply.
