The volume of the loans, and their nebulous final status of ownership (who holds the deed in trust? The MBS owner?) meant that there was extreme looseness, nay, even criminal sloppiness in the handling of the origination paperwork. After all, these loans were going to be refinanced long before anyone needed to look at the details.
Boom! The recession hits with a hike in oil prices in 2007. People who are barely making their mortgage payment start defaulting, drying up the MBS interest payments enough to scare off future buyers and, more interestingly, triggering credit default swap payments that insured the aforementioned MBS. Long story short, the bubble bursts.
Now that the banks are trying to recoup (in order to stave off their own bankruptcy) these properties through foreclosure they are finding the things aren't going so smooth. The paperwork is missing and they can't quite establish that they have standing to foreclose. They forge ahead anyway.
Sorry for the pedantic outburst, I really wanted to get it down to establish for myself what I think is going on. I don't think that people who defaulted on their loan should get a free house, they too are culpable. The mega banks that are up to their necks in this mess should taken over and dealt with like any normal bank that goes into receivership. They are bankrupt right now and no public money should be used to help them or special legislation passed to haul them out of the fire. Stupid and greedy should hurt.
The whole thing can be resolved if they all get together and unravel it, and yes, it can be unraveled.
The mortgage people, the real estate people and those who bought those houses are all to blame, as well as the bank that sold and resold the mortgages. There has to be a solution. There is not sufficient time to allow for the unraveling.
