You are between the Rock and a Hard Place:
They have changed the locks, but insist that you still own it.
You have to have insurance on it, but you don't have access.
You are not paying anything for it, but don't occupy it.
You are responsable for it, but....
By moving out, you might have lost the opportunity to get the Cash for Keys.
Your Credit is already ruined, the next few months aren't going to make much difference,
other than the clock has not started on your waiting period for another loan.
If you know how to contact the Bank, or their Kisting Agent; you should share these points.
Good luck and may God bless
