I appreciate the advise.A family member which is a certified paralegal has offered to help pressure them.

New tenants will be moving in soon and they mentioned mounting a flat screen TV.

invested $40k into driveway, new acs, paint and pressure wash.

We always mount our TV using good quality mounts.

Not an empty few words just because maybe this constant inbox notification put so much pressure on you. 

2) she is pressuring us to check it asap, and she gave us a 16 hour range that she was not home.. and we are very busy, just curious how do you go about it?   

The only problem is the houses become valuable, taxes go up, rents go up more moderately, and I feel pressure to sell/exchange and get my yield up. 

I am really against this deal, but it's due to family pressure and the family tensions that I have to go this route.

If they pressure you to do something before you've done your DD just punt it.  

Then present to the seller with a counter-offer.In Michigan, once a seller is made aware of an issue, theymust update their Seller's Disclosure form - which will put pressure on their asking price going forward.
