Basic property management question

[Erik E.]

Sorry for the newbie question... With property management companies, would I need a minimum amount of properties in my portfolio to have a property manager cover my units? Example being, I live in DC, and I see a good deal on the west coast. Could I plan on buying that one property and have a property manager look after it or would I probably need 10 or so properties in the area before the manager will deal with me?
