questions for a property manager?

[Mark Ormerod]

I'm meeting with a potential property manager and was looking for advice wrt questions (and answers!), and on deal structures, typical %. 

They are a real estate agent and private re investor, and they are self managing successfully, but don't have critical mass. I'm looking for someone in the area who could manage 3 or 4 sfh, but low income, rents 500-800 range.

I live here, but am away too often to self manage, and finding a decent pm company seems a fool's errand.
