My parents rent out a room to a traveling nurse since my brothers and I moved out, the space was just going to waste. I'm not positive on what she pays, but I think it's around $500.
My parents and grandparents own rent houses. They're active property managers. Most fixes they do themselves. My summers growing up were working on them.
I think the difference between what they do and the corporate owned apartment I'm staying in is the "personal touch" (for lack of a better term). When the owners have never even seen the property, they see renters as numbers on paper instead of people.
