However if the bank had agreed executed contract they are held liable terms and conditions of accepted offer. Banks have different concepts of their business practice than with a normal seller, it must fit within banks "box" anything outside of box may not even be considered.
Confer with buyers agent or attorney determine if you have any recourse .
I am a realtor in the North Atlanta market and very familiar with the foreclosur process. The bid is not final till the bank signs the contract and become binding on all parties. The banks/asset company handling the properties for the banks disclose this stipulation in their contracts. Did you have a buyers agent representing you. It is very important that you have someone represent your interests in the transaction as you could loose your earnest money if you do not follow the process.
Good luck on finding a home..

This happens frequently. Banks accept an amount verbally and recant on the agreement. There are many reasons why, but the biggest issue is how they are able to do this and get away with it.
This is not professional and essentially is exploitation of the potential buyer. At least at this point there seems to be immunity to being held accountable for these actions. In many respects, they are out of control.
