You should check in with a mortgage broker / bank to see if you qualify for a loan, and if not, how far away are you from qualifying.
If you are close to qualifying, craigslist has a ton of rent-to-own listed. Also, have a Realtor search online for homes that accept lease option as a form of financing.
Feel free to call my cell to discuss further.
One of the best ways is to look at rentals in your area and ask the owner if they would agree to sell it to you if you were a good long term tenant. If they are open to the idea...then you could likely set up a "rent to own" agreement.
