Under contract on property. Just completed inspections. Inspector noticed there have be at least 2 different extentions to the original home.

The home is currently a 3bed 3bath 1600sqft home with a pool... I plan to finance the property conventional loan but I atticipate the appraisal will come in low due to the unpermitted work.

Anyway thats pretty much the situation right now. Im Looking for someone with experience to chat with
