I have put a contract out on a 1978 2 Story house. I have since noticed a few cracks that are causing me some concern. The cracks are present at the top of the door frame extending outward and upward. Are these cracks due to settling or structural problems? We were convinced by our real estate agent to decline the home inspection due to the competitive market. (Big mistake) We have not closed on the house yet and feel like this is the time to get to the root of the problem.
