You'd have to seriously prove beyond a reasonable doubt (or a small claims judgement) that this person was NEGLIGIBLE or INCOMPETENT and I seriously doubt the $2000 it would take to fix these issues versus the X dollars it would take to contact a lawyer, bring them to small claims, etc., would make it worth your time.But, if you insist on going down this path, check your contract/invoice with this company.

You might want to do the tear out too to save $.I doubt that you need a GC for this. 

Going to check to see if his loan is assumable but I doubt it. 

I doubt it.For example, I found this listing for $569k, which works out to ~$170/sq ft.

@Hub Knott I doubt there is a solid number out there you can count on.

No doubt.  

@Sam Trentwood she is a chemist and I doubt in this area she will have a problem finding a job.
