I lived in a rental house for 2 years (near Southern & Kyrene in Tempe) that was managed by this company. It was decent. The main Realtor was kind of your stereotypical.... Realtor (interpret this as you will), but the other folks working there were always very friendly and helpful. Maintenance was pretty prompt.
The only bad thing was that we were robbed, and they tried to bill us for the damages to the house. There was a little argument about that, but it was resolved quickly and we weren't charged in the end.
Oh, and they failed to mention before we moved in (or after) that all the remodeling was done because of some disastrous flooding (only discovered this after my insurance agent was looking up the history of the house and said "WHOA.") It would have been nice to know, considering my roommate and I were both really allergic to mold. Next time, I'll ask.
