Small Business Owners & Entrepreneurs

First, there should be laws in your state regarding notification of tenants when the building changes hands. If there is a law on this subject, the bank loses a point for not notifying you. You could, particularly since there doesn't seem to be anyone in charge, just not pay rent until you've recovered your security deposit, and then move. There are risks in this. The bank could demand the rent, and then you'd have to pay it and then turn around a sue them for your deposit. What seems to be happening here, though, is that no one has taken any responsibility for the building, which would, as a practical matter, limit your risk.

As for your lease, if the bank doesn't know you have one, you're not obligated to tell them. (Under normal circumstances, when a rental property is sold, all the leases, deposits and prorated rent are transferred at the closing.) You could just pack up your possessions and move. If you do that, I'd suggest notifying the owner that you're doing so, just so they don't try to sue you if there's any damage once you move out.
