Since you have been discharged from the bankruptcy. Did that inclue having to pay your bank any more money? If the home is not yours free and clear - stay. If the bank fought the bankruptcy and you are suppose to pick up payments or at least negotiate for new ones or if you don't want to stay then cash for keys may work for you.
Cash for keys is a term that banks would prefer you didn't know anything about and for years they have kept silent about it. Now many banks are quick to initiate a cash for keys policy as standard procedure.
Cash for keys is a way for homeowners in foreclosure, or for tenants who are victims of foreclosure, to receive cash in exchange for surrendering the keys and vacating. Banks generally reach an agreement with the occupants of a foreclosed home, which stipulates the home will be left in good condition and cleaned. The agreements typically set forth a specific date that the home will be left vacant, including a promise from the occupants that they will not vandalize the foreclosed-upon home or strip the foreclosure of light fixtures, appliances, copper, etc.
The bank after forclosure is now responsible for the home. If the bank has to spend a ton of money to repair damage caused by the occupants, that money increases the bank's loss. It is really in your best interest to approach the bank humbly to get what you both want.
When you move out there are reasonable expenses you may expect to recover. Some of these are the following: A security deposit and first / last month's rent, Movers, Rental truck, Utility deposits and temporary living quarters such as a motel. If you agree to an immediate move out - some bank might pay a bonus.
It is really in their best interest to work with you and your bankruptcy discharge as nothing to do with cash for keys. They may want you out more than you know and it never hurts to just ask.
