"Cash for Keys" is a program that could apply to your loan if your loan is a government backed loan, and there's a short sale that needs to happen to sell the home. Once there is a contract on the home, and the short sale is being worked, the lender could approve up to $1,000 from the lender to the homeowner to assist with the moving out of the home.
Careful, this is not always the case, and if you have a second lien on the home, sometimes that lender will demand that money in order for them to accept a short sale on their loan.
There is much more, I would do some searches on the web. First off, though, I'd make sure that your loan could be a candidate for this program. Best of luck to you.
