Brian, isn’t your scenario just a paperwork problem. Now if someone sold you a car they didn’t own, well that’s a different story. But if the title is lost, or destroyed, who cares, get a new one. Pain in the ass yes, but catastrophic no.
So are banks selling something that is actually owned by someone else. Or are they just not passing the mortgage around when they sell it.
Maybe it will take a mountain of litigation to find this out.
