How do I pick a property management company?

[Douglas T.]

I'm leaving Chicago for Ft Lauderdale and renting out my Chicago condo.  My goal is to pay a fair price for good service and not be taken advantage of.  I regularly deal with two mgmt companies that I own properties with.  One sucks and I wouldn't use them even though they manage the building the unit is in.  The other is great... wonderful, timely communication and great customer service.  I intend to pursue that one, but thought I should probably talk to at least 3 companies.  I'm not even sure what to ask these companies.  I'm really scared I'll miss something important.  Any time I try to find reviews of other companies, they're all bad.  I'd appreciate any information or direction to get this thing handled correctly.  Thanks!
