This is a bad plan, because the bank may not own its building and land, and may just be renting the space. The actual owner/property management company might have a contract with a towing company which the bank would not be party to. Depending on state law, you could find yourself liable for towing...

It sounds to me like it's time to close the business, default on the business's debts, and attempt to settle with the creditors. You have too much property to risk in bankruptcy, so that is not an option. The important thing is to cut your losses, and close the business ASAP!
