How to use a mistake to my advantage

[Michael H.]

I recently looked at a home for my personal use (not investment), and the house is listed as a 5 bedroom house. However, in GA, to be considered a bedroom there has to be a window and a closet. And the 2 "rooms" in the basement do not have windows. So legally, I'm pretty sure it should only be listed as a 3 bedroom house. I'm trying to think of ways to use this to my advantage. The only thing I've come up with so far is hoping it doesn't appraise for the agreed upon price once the appraiser sees it's only a 3 bedroom house, not 5. 

Any experience someone has with something like would be appreciated.
