When I moved away, I tried to hire a property manager, but as I only had 3 fairly low-priced units, none of the established managers would take me on. I naively hired someone who had strong references, but for commercial real estate, not residential, and she made the whole process such a nightmare that I gave up and sold my units. (It had become impractical to step in for her when she failed over and over again.)
Once bitten, twice shy, as they say. I took the 50% increase on the value of the property and the 3 years of covered housing expenses combined with massive internal resistance as a pretty good sign that I didn't like the process even when it was profitable.
I might try again someday, but I value the lack of stress an awful lot.
