if you want to give me a call at 866-936-5363 ext 278 or shoot me an email with your contact info I can try and help you.
As stated, we're really going to need some more information to determine anything.
Income, credit, and down payment are the 3 main things EVERY lender looks at in approving your loan. It sounds like credit may be an issue, but it really depends on how low those credit scores are. You might need to do some work on improving your credit before you can buy again, but like I said it depends.
Contact me if I can help
