How can I find an FHA loan for a small amount?

I can not find a lender that take small amounts for what I am looking for. The house I found is 12,000 and yes it is a foreclosure. But my credit isn't the best either but since the loan amount is so low would they even consider it? And I am willing to put up to 20% down for a downpayment. What steps should I take? Any other ways to obtain it??
