How many units can one person manage?

[Doug French]

Background: I currently have 30 SFH. 8 of these are model homes that I lease back to a builder NNN (minimual management) with the other 22 units being new construction (less than 5 years old). I currently have my personal assistant doubling as a property manager. I am growing this business and plan on building (My other business is a production home builder) another 15 - 20 units this year.

Question: How many SFH units do I need to keep a full time property manager busy? In my head I always thought 60 units.

Put another way: How many SFH did you have when you hired your first full time employee to manage property?

Thanks in advance!
