You may want to consider a rural housing loan. They are a little more flexible!

I have lenders who can go down to a 530 credit score, but usually there are a few key things we can do to increase your credit score to where you can get a prime loan and save $30,000 over the life of your loan.
Ed is right- that it must meet FHA/VA or RD standards BUT each lender has different overlays. This is why you need a knowledgeable loan officer with more than one option.

Use caution. you'll get offers from lenders that won't really be able to get you a loan at a decent rate. Contact mortgage bankers only and ask for pre-approval for a FHA loan. Kathy Tautfest (405) 616-7517 at Bank of Oklahoma does a great job and they have many programs fro first time home buyers. If they can't do your loan to FHA standards then no one can because they all use the same rules.
