So I would suspect they would be a good start.  

I suspect the excuse of not being able to move anything due to the divorce is just that...an excuse.It doesn't mean they don't get to pay rent. 

Depends on how large your job is, if any materials are left onsite, and if the area is suspect.

I suspect he is over his head regarding any sort of building or renovation work and would be better served paying someone that can do it right.If he wants to learn that is fine but if not he needs professional help.

The system I suspect may have never been wired correctly to begin with and that is unfortunately a common problem.

I think the only time they would investigate is if they suspect foul play or a crime.  

Suspected unpermitted work?

Meaning I suspect the Seller's broker might have made it up to squeeze out more money now that we are so far in.

I just want to make sure I interpret the records properly, and that there is in fact multiple mortgages on the home as I suspect, and not that those records are just showing that theres a new lender in place of the old?

I suspect that no matter which avenue you choose, opportunities will come up for you and If an opportunity that is simply too good to pass up appears for you in the "other" track, then make sure to run it by experts in that field but do not hesitate to grab it WHEN you know it's right.
