You will also need to know where you are going. If finances are tight, buying a new home may be out of the question, plus it is unlikely you would be able to close as quickly as you would need to move in. That said, you may choose to rent if you sell your house to avoid foreclosure. You will need to be able to pass a credit check and come up with first, last, and security. If it comes down to it, ask family or friends to stay with them until you are able to find new housing. A sale to a direct buyer can happen very quickly.
