a few options come to mind. 1 call their emergency contact, 2 offer to let them out of their lease if they are unhappy, 3 as a last resort send them a no renew.

We have a resident that almost mirrors the complaints you have listed. She had a brain tumor. We gave her a written list of her options and reference it every time she complains: move with out penalties , see if noise canceling headphones work, transfer to a top floor, come into the rec room to use her phone so they can’t tap her phone, open her mail in the rec room, etc. She is stuck based on disability and the low rent she pays until she comes up on another low income waiting list. We did our due diligence in checking to see if the issue was real and we document all interactions. It has been ongoing for years, and any new person at the office gets suckered in at first. Unfortunately these situations just don’t go away unless the resident moves.

I try to explain what’s within my control and what isn’t but a non-renewal is the next best thing

When I had complainers like that, it usually meant they were guilty of something, themselves. I had one who complained about everyone around her, then complained about her ac constantly. Maint swore on everything holy it was fine. Long story-short, she had family staying with her and didn't know how do lock them out and wanted to transfer (+they had bed bugs). Another complained about everyone around her throwing trash on the ground, not picking up after their pets, loitering. Turns out her neighbors were confronting her about parking in the handicap spot without a tag. But she swore she deserved it cuz "her feet hurt and she's old" (her words) Oh, and another complained that the sidewalk was too cracked and made random complaints about people that live on her sidewalk route because she wanted us to assign her a spot in the back where residents illegally parked. I've had a few complainers like that, and it usually means they're trouble.

I've experienced neighbors with legitimate mental health issues and the strange, scary, and loud behavior the accompanies it. I complained to my (private party) landlord who had no clue how to handle it. Eventually, the neighbor's family reached out to the landlord and they performed a well being check. After the family got involved, things improved. The landlord non-renewed the neighbor, which is what I would recommend doing.

There have been residents in the building I manage who have mental illnesses. Contacting the family and non-renewal are the most effective ways of dealing with this behavior.
