Can you get some help from family?
My dad and aunt have clubbed in together to snap up a few properties at auction in Houston, but you need some capital to ride out the slump.
If you could get some capital, perhaps you can try auction properties? You need to have cash or a business loan for them, however, for the most part, instead of a mortgage.
It's very difficult to obtain a mortgage at this time if you are considered a credit risk - no credit or bad credit, for example, but that can be helped if you have some capital for a large deposit or can buy a home with a family member who has good credit, for example.
