On QM loans, you also can use what is known as asset depletion.

I have to imagine there will be quite the cleanup after they move out too. 

Other small things while turning over a unit is; new toilet seats, new lighting in bathroom, new handles on all doors, new fixtures on sinks, ceiling fans in all bedrooms, supply a washer & dryer in my duplexes, and clean up the entrance area for a good first impression. 

It makes you negligent if something were to happen because you didn't take care of what you were responsible for, and if you were very aware, specifically, of what you should have taken care of, you could be found grossly negligent, if something really bad happened.So, I'd just clean up the mess, tell your tenant you're taking care of everything, and tell your neighbor you'll pay a reasonable cost to repair any damage. 

There may be an initially higher cost to get the current infestation under control, but then going forward, it should be just the regular monthly charge.What I'd do, is give the tenant written notice about how you are taking care of the infestation - that you've hired such and such company, details about how they are dealing with the infestation, and how they will be treating monthly going forward, and enclosed is the information the company provided about how the tenant needs to clean up food laying around, and take the garbage out regularly, etc.  

I get trying to clean up the city and prevent crime but taking it on landlords probably isn't the way to do it. 

Clean up several hundred bucks on top of that. 911 Restoration quoted $1,500 to snake and clean up. 

Now, I have to repair damages, clean up the property, then find another tenant.

What we're afraid of is she'll abandon her duties to clean up the grow facility and it will take a considerable amount of time to fix it up ourselves.  

My wife worried that they would live slovenly and only clean up for inspections but I figure that if they care enough to clean for inspection then they probably are not trashing the place that badly.
