-Government regulations aren't as toxic as they were in the early 2000's regarding housing.

I am very happy with the carrier(s) of my other policies for personal auto, renters insurance, health insurance... so this is becoming really irritating, to say the least.

Non-payment is usually acceptable, but what about the irritating, constant minor violations, or unproven issues you don’t want to go to court over?  

Look for any indications of toxic activities occurring in or around the house.

I called the main office, and they informed me that there has been no flooding in the basement, no burst pipes anywhere in the building, and no roof leaks in the last few months.I offered that she pay for the assessment herself (from a reputable testing company, not a remediation company), and if it comes back positive for high levels of mold or toxic mold (because I know mold is everywhere in the air) that I will reimburse her the cost of the test and remediate the mold - if it wasn't due to tenant negligence. 

Still feel blessed, no threat of losing properties like others in our state, but irritated that the delinquencies are not due to COVID, just poor eviction moratorium policy.

Doing anything else is just going to cost you time, money & irritation.

It will irritate you when your paying several hundred each month in utilities.

Larger concern is the toxic materials are released and can be absorbed through your lungs, eyes or skin.

Make sure you're only irritating the landlord, not the local authorities, if you feel you must go that route.I'd try explaining to the property manager about your situation and seeing if you can early terminate or sublet it to a long term tenant as the first option, though.
