Living in a four-plex with three tenants who have constant needs

[Jack B.]

I like having a MIL apartment, kind of like a duplex. Only thing is new tenant has yet to live there a full day and is already expecting me to let in his son, etc.

As much as I find it convenient to deal with contractors and prospective tenants living on site myself, one downside I'm starting to find is these strange little requests the new tenant makes. I'm just wondering when he will ask me for a ride because his car broke down, or to borrow a cup of sugar.

So that makes me wonder how it would be if I bought a four unit apartment building and had these types of tenants constantly making requests. Easy to say screen them out, but you can't always tell up front, and constant turnover is expensive.
