Sounds to me like if your loan was packaged and sold as CDOs somewhere you are probably shit out of luck. Banks might work something out if it's still "held for investment".
If you have more than 3% LTV, the bank would just foreclose if you can't pay, they get enough money anyway. If you have less than 3% LTV, the bank would just milk you for as long and as much as they can and hope for a miracle, or until this whole thing go kaput. It's all about helping the lenders anyway.
