i live in north carolina.recently i attempted to purchase a house.i have a contract to purchase signed by me and the seller.in this it states that the loan is a fha insured loan.the day before closing the lawyer informed us that it is a law that the seller must assume a certain percentage of the closing costs.we were never notified about this prior and neither was the seller.now the seller is not sure he will go through with the sell.is there anything we can do about this or will we just loose the house?
