The contractors who do work for me have zero issues with me sourcing the material if disclosed up front and not holding them accountable for any material issues.  

Theft is a HUGE issue there ..

Have you run to ground all the more common issues?

My tenant had an issue with the 1-year old dryer working.

Every deal has a challenge—whether it’s a seller with an unclear title, a property with zoning issues, or just finding the right buyer who actually sees the value.I’ve been navigating all of this while working on land and mobile home deals, and honestly, the problem-solving side of it is what keeps me hooked.

I know that their email is accurate, and that is not the issue.

There's a good chance the issue(s) you face has already been discussed and answered.Ask questions in the appropriate forum.

Maybe call those owners and see if they've had any issues?   

The only issue I've had is a small period where the laundry pods would always be empty at turnover. 

For the proceeds I have to pay seller I would have to issue him a 1099 right?
