Land Contract or Rent-to-Own situations might be your only option for now, but there are credit repair programs that work directly with some lenders and can help you get approved for financing much faster than if you were just to try to repair your credit on your own. If you would like a referral to one of these programs to see what it's all about, let me know. I have dealt with a few people who have said nothing but good things about these programs. Let me know how I can help. Thanks!
I agree with Brek, getting you credit cleared up is the first step - even your home owners insurance will be at a higher rate if you do not fix this as they use your credit score (among other things) to come u with your rate. JIll is right as well, rent to own for now and work on your credit so you may purchase.
I understand your situation, have you talked to a lender to see how you can start to repairing your credit. that would be the first step, then maybe you can buy a house in a year or so, or you can start looking for homes that offer rent to own opportunities.
Hope that is helpful
