My partner and I rented a house managed by Excalibur for a year. When we eventually moved out, the main reason we were moving is because of Excalibur. I want to preface my comments by explaining that we were.
I honestly can't say enough bad things about these people. Steer clear! I've rented through 2 other property management groups in Atlanta who were great! I lived in my Excalibur Homes rental for 4 years.
