For what purpose? The loan contract states that in the event the homeowner doesn't pay the loan, the bank gets the house. The bank agreed to that up front. That the bank doesn't want the house now because they loaned too much money on an overvalued asset doesn't suddenly make them the victim here.
That is lost on too many people. That is why abandoning the age old practice of getting a down payment (i.e. skin in the game) was one of the first telling signs that we were in a pyramid scheme. The banks seemed to be unmoved by the risk they were taking on, as well as it's implications. They are now reaping the rewards of their unbridled exuberance. And they have ONLY themselves to blame.
