The realtor on Metchosin said the reason why there is a hole in the sunroom is that the seller is due for a septic inspection, he has to get one done before the end of September and is just waiting for the septic company to come by. He also said that the seller will do whatever the buyer wants to do with the sunroom, either finish it off or take it down, the seller is willing to help the buyer with what they want.
Let me know if you have any questions.
