Unpermitted bedroom addition

[Timothy G Dunson]

Hey everyone,

im under contract on a 5/4 duplex. I just found out that they turned the dinning room into a 5th bedroom in one of the units. The house is for sale as is. It seems to be priced as a 5/4 and not a 4/4. The seller didn't mention an unpermitted bedroom in the seller's disclosures. 

My question is. What should I do? Ask them to get it permitted? Ask for a credit? Ask them to change it back to a 4/4? Ask for a price reduction? Or just pull out of the deal?
