Are there any lenders who will combine my debt and give me a new home loan? Really bad credit from 8 years ago

I got into a hole about 8 years ago with my credit and now I'm trying to buy a house. (less than 70,000) But my credit is a huge factor and I cant find any lenders that will work with me. My debt is about 20,000. I have a car loan now with a co-signer and payments are never late. Any info would be greatly appreciated.
