Perhaps a really big point is being missed somewhere along the way. Have the occupants being making their mortgage payments or not? I agree the banks may well have royally screwed up the paperwork in the bubble frenzies, but leave this to a judge to decide. In the mean time, the courts should assume control of disputed properties and kick the FB’s out given they have ample opportunity to demonstrate they have indeed made payments as agreed, or the bank does not have the right to reposes the home as it is a wrong address etc.
FB’s who cause issues should also be notified that their loan apps will be subjected to criminal investigation if it turns out they lied substantially on their application. Particularly stated income loans.
