At worst, you are ruining someone's life and could end up in legal trouble.

Also we have extreme hard water that builds up and ruins fixtures and surfaces if not dealt with regularlyWhen I was in boarding high school in the 1980s, our dorms were crappy painted cinderblock 1950s buildings with commercial vinyl floors, but all rooms had private baths.

I also ensure that the rent isn't incredibly low where if I increase up to the allowable max it won't ruin the deal.

This can easily ruin an otherwise successful real estate investment.

Before I could mention the rent increase he states he has cancer and will be starting treatment.

Does this ruin the business model?

Demand Drivers: corporate HQs - project/business travel, large construction projects, relocation travel - significant population in-migration, military/government, large hospitals - travelling nurses/doctors and overnight patient stays, training hospitals, cancer centers, leisure travel, universities, high occupancy in extended stay hotels, supply constraints, close to transportation corridors, shopping, and entertainment, high cost area (housing, rents, hospitality)

Ideally you would have insurance to help out, and then the LLC just functions as a "backup" in case things go really wrong or insurance doesn't cover something to keep it from ruining your life.

I've heard of a lot of people having problems with their units being ruined but I have not had that experience as of yet, knock on wood.

If they say no rules for STR's, do whatever, freedom reigns, next thing we know it's complaints how the city "let" the market get flooded with "all the STR's everywhere" and how this one is a bad operator, that one is a "puke" and, back to the start "wtf, why are they letting this happen, they suck at there job, they need to be doing something about this"....Reality is, it's society's fault, they make rules to prevent dumb stuff from happening because some dummy did it, so now they gotta make a rule on everyone because of it, so thank that dummy for ruining it for everyone.
