I would not do it. If you have to go thru them you will end up paying tons in interest and fees as I am sure it is a subprime lender.
You need to get yourself in a better credit situation. There will always be homes. That is what you must tell yourself.
Much better to rent a decent shack, save up $, pay yourself first, build up your credit and then get a home.
Much better than foreclosure because you bit off more than you can chew just to high hopes.
Sorry to be so blunt. But have seen people loose their homes.
