I have family that is moving to Philadelphia and purchasing their first house. They are both architects, they have good credit, they are solid buyers. 

They are in contract to purchase a home for $395k (asking $409k), home on the market for 28 days, sellers did not counter their offer. Inspection (they attended) came back overall very positive with two possible red flags. 

Cast iron sewer line came back with cracking and the basement floor had a patch of some serious cracks. We believe the foundation is in good shape besides the one obvious patch. 

The last day of their inspection period, is tomorrow. I want to throw this out to the community to see if anyone would have some local expertise to know if market conditions should warrant a request for seller credit or break the contract.
