You can ask the bank, but short sales and foreclosures are pretty much "as-is" and I am positive you were fully aware of that going in. Do you have an accepted offer? If not, why even bothering doing an inspection? If you do not have an accepted offer from the bank, you can ask anyway.. It will definitely help determine whether or not the bank will even accept the offer.
Just from experience and guessing where you are at in the transaction. I have learned that agents with little or no experience in short sales have their buyers enter attorney review and waste money on inspections when they do not have an accepted bank acceptance in writing.
Either way.. ask. All they can say is no.
