sadly if you try to be a good landlord and make a slim margin, you'll get dumped a huge repair bill/tax increase/other expense and now you're running the appartment at a loss. At that point you either sell it to a company willing to exploit it or you have to be less nice to your tenants and ignore repairs or charge more. Most people choose the first which is why we end up with terrible landlords.

aside: heard someone in that exact situation running low income housing, on a phone call with an expert talking to the government. The expert said "any prudent management would raise the rents the maximum allowed amount"

They have once a year paperwork to do and still bitch and moan and they still call it work.

It's disgusting.

The one "person" I know also drags tenants to court over stupid shit (he always loses 🤣)

Where I live landlords (if they're renting directly at least) are in a big legal responsibility over all kinds of stuff. The easier way is to rent through some company that deals with the renter.
