Getting a Subprime loan will be tough in todays market with the foreclosure crisis. There are options out there like lease to buy. With a poor credit history, one thing that will help is a substantial down payment. Also, be prepared to pay high interest rates, too. You might also try FHA, Freddie Mac, or Fannie Mae.
If nothing else, there is "Hard Money", which means your loan is from a non-bank institution such as an individual or small company. Hard money usuaully requires 30% or more down, and is very costly interest wise. But the advantage is that they take people with bad or no credit.
