AN it is an indirect lack of financing. That is, you cannot get homeowners insurance on a home with a cracked slab. Without the insurance you cannot get financing. Although if the appraiser noted a cracked slab then the originator of the loan probably wouldn’t do the deal. You can get cracked slab deals done but getting an arrangement prior to even attempting to get the financing is the best way around it.
Agreed about the deal breaker stuff. I have seen many a buyer walk away from homes over things I personally would not sweat.
