I wanted to post an updated current review, as I am surprised to see so many negative reviews. We are still renting that same house and have very few problems or complaints with them. It's not perfect, but we have not had the nightmare experience many have described here.
Some of the contractors aren't so good, but that's not resys, and it's never been horrendous. The owners of our house have a home warranty on the place, so the home repairs are taken care of quickly. Anything we pay out of pocket is taken out of the next month's rent with no issues. We've never had our mail returned to us when we pay our rent either. Again, our only headache is it often takes too long for them to deposit our rent check.
I would consider using them again.
