I did maintenance for a low income building. They would have me upgrade specific units so they could Airbnb them while they denied low income applications to keep those units empty. Disabled people who needed housing were denied because it was more profitable to leave it empty and rent it out to tourists a few times a month.

We also didn't do maintenance on specific units in order to get tenants to move out. There was a specific unit that was given to new tenants that would routinely flood. They used it to get rid of people that complained too much. If you only complained a little and cooperated with their bs, you could eventually move to a unit that stayed dry all year.
