Choosing a Property Management Company

[Matt Batson]

I had begun talking about my PM on the other thread, but felt this needed a separate thread/discussion.

My question is, how do you guys choose you're PM? What services do you look for?
When I chose mine, I had called around to different PMer's in the area, along with real estate companies, and from more than one conversation the name of my PM came up.
I know this isnt very scientific, but figured recommendations from people who had nothing to gain from it seemed okay at the time.

Adam Black from the other thread, owns his own PM, and he brought up a great point. He offers, free of charge, a 45 day change of the a/c filter along with a 20 point inspection.
I have to tell you, this sounds awesome.
I am now calling other PM's in the area of my rental to see if anyone offers anything like this.
One question I would have is, what are the 20 items being inspected?

How do you know if you're PM has a good reputation?
