It depends on how far along you are in the foreclosure process. First off you need income. Second, communication with your lender is extremely important in the early stages. If you are in the latter stages, you can get a loan reinstatement. And lastly you can file chapter 13 bankruptcy even just to delay the foreclosure sale if time is needed to either get the loan reinstated or to find a new place to live. If you do have to move, make sure to negotiate a good cash for keys deal with the lender. They will give you thousands of dollars to move out and leave the property in decent condition within a 30-60 day period.
