Thanks all. Jeff, I appreciate the links and advice you provided. I agree pictures may not tell the whole story, but I thought the almost footwide patch would be more compeling. But I would also be reluctant to base an opinion on a picture. No repair work has been completed to date as the cracking appears to be tied to a bad sewer line below the slab which will be a major repair (and has been repaired in the past - which wasn't disclosed). Do you service Yavapai? Basically, we are waiting on a response from the seller now. I hate to get the HI stressed out before we know if we will need to go to court. Is it normal fro HI's to get called as an expert witness? I assume we would want him on our side to show that this was an act of concealment that even a home inspector would miss. Court is not something I am hoping for, but I want to get my ducks in a row now.
