Some promoting more than value-adding.

Put up with the situation and avoid her as much as you can, move on to somewhere else that won't be as nice in some areas, but better in others, or the last, decide if you want to stir it up with rent control, or the health department or whoever oversees rentals in your area. 

Even though I loved the ad, I wanted to identify a pernicious pitfall in the thinking it promotes.

First one was chalked up to COVID but he was 63, had at least five major health issues, was 100+ pounds overweight, and didn't seem any medical treatment.

Wishing you health and good luck.

You can't self promote here, you can't blast your services out there saying "use me" every time your city pops up.  

I’m inquiring about options for health/dental care.

However it is nowhere near as easy, simply or risk free as promoters suggest. 

Out of curiosity, would users on here be interested in LP contributions or potentially buying into the GP promote?

This is one of them.Inform the tenant that having old food around the place is the likely attractant for the pests and that this is a serious health and safety issue and you need them to clean up their unit ASAP.
