They're supposed to do all those things but most don't. I'm a condo super and the owners who own and rent multiple units are the worst.

Those landlords tend to own multiple units and just assume I will deal with their issues, but I won't. When you own, you're the super, manager, admin, etc. But most landlords I've encountered just wanna collect the check
