Banks will never ever lose.
Quick story- I know this guy in the Greenwich area that buy mortgages out from under people.If he likes the house you live in he will check up on you to see if there is any turbulence in you're payments,if in probate it make his job easier. He will approach the bank holding the property and offer them a much larger sum than what the owner owes,making it irresistable to the bank.The bank agrees.
Now that he owns you're ass and you have to pay him to live in you're house he somehow alters the contract so you breach the payment agreement,takes you to court and takes you're house from under you.
The bitch is it's all done lawfully.Real nice guy,aye?
