subprime mortgage is no recourse, when the people return the key to the bank if the equity amount is less than the market price, when the house is foreclsoe, they take the whole thing from the house, rugs, appliance, decoration, pipe, the house is badly destructed, the bank want to get away from this obligaiton as much as possible, so they sell the 5 house for a cheaper rate, hoping the maintaince level can be maintained and the value for the area can be restalled.
