Ideas on finding a good Property Manager out of state?

[JR Hinds]

It looks like my next purchase will be out of state. I know people in the industry in my home town, so it's not difficult to find a good property manager and stay on top of them. But finding a good property manager across the country will be more difficult. Does anyone have good suggestions for identifying a few good property managers in another city to interview? And then do you have suggestions for how to interview them?
