I'm sure there is a compromise easily in there somewhere where you can pay a licensed business to do the work and receive an invoice for your $1500/etc.

Just want to see how much work and money it took to get that LLC started?

Its a matter of time but the cost to own and maintain them vs. what you will get as a STR does not work, and as a LTR they absolutely do not work.

With that being said I believe there are multiple approaches to a situation like this. 1, being you let them out of there lease with refunded rent from all paid months the tenants have paid. 2, You take the safe and correct approach and get it tested and properly cleaned if needed to continue to be a potential success landlord, not testing or cleaning a meth infused house is very bad for anyone to live in, so you just continuing to rent it out without finding out the truth behind it all, would make me hope you don’t continue in this line of work. And

I remember a time back the folks at Bigger Pockets were promoting Josh Cantwell, Appearantly the guy has salesmanship but look up the details of what he offers and you will find he wants the best deals, a sure profit and at minimum 16% on his money, plus he gets you to do all of the leg work and contruction but he gets to select the deals and control all of the money. heheheh When Josh was just a young lad he was told that, "there is a sucker born every minute" then instructed to go out into the world and find them.

If the deal doesn't work, it doesn't work, and I don't want to go further because, to me, it is about relationships. 

If you try to take shortcuts, you'll wind up in trouble.

Now we are past the drywall stage heading into shower and tile work and I have to go back and deal with something that I should have dealt with earlier.  

Have you considered exploring other paths, such as taking a gap year to work and gain some real-world experience before making a decision about college?

I think you need to talk to the PM about how repairs are going to work and specifically for the case of tenant damage.
