Unpermitted Work Not Disclosed - Past Inspection Period

[Brandon Hardiman]

So I am under contract on a property and I am past my due diligence phase. However, I have discovered on my own by chance that half of the house was an addition put on by the previous owners and no permits were ever pulled for it. This is in Alabama. Since I did not discover this during my due diligence period, am I legally obligated to still forfeit my EMD if I back out? Or can I back out on the ground that this was information not disclosed to me by the seller? There are no agents involved and I used my own purchase contract. I am a wholesaler and was going to just take it down myself if didn't find a buyer at the right price. But now I really don't want to take on the risk of an unpermitted addition and not getting appraisal value, insurance issues, etc...
