GM says open to moving from Detroit headquarters

Normally in that situtation, the borrow still has to honor its obligations to the lender even after the lender forcloses, but when a company files for bankruptcy protection, it wipes or or greatly reduces their outstanding liabilities.

Not exactly, artds. Most [[if not all) commercial real estate loans are non-recourse. That means a lender's sole recourse for a borrower's failure to repay the loan is to foreclose on the building. If the building is worth less than than the loan balance, the lender is out the difference.

Your other point is correct. A bankruptcy judge could easily determine that the 'new' GM didn't need the RenCen. Depending on the difference between what the value is currently to the balance owed, what GM's equity is and whether loans on the RenCen are secured, the judge might order that the RenCen simply revert to the lender, or be sold and the proceeds distributed to creditors, or the lender be required to pay some amount to get the facility back.
