Costar is quite possibly the worst company I have ever dealt with. Their product is subpar and customer service even worse. Ive used their service for a year and decided on another real estate path. Costar refuses to let me cancel my subscription or allow one of our new team members to purchase the subscription. The few times I HAVE attempted to use the service, it was unavailable. Their reasoning is I am a principal. Simply because some of our agents do commercial real estate, they are requiring me to continue a subscription. Deceitful, fraudulent, and unethical all describe this organization to a T. As I work to report them to the Better Business Bureau, I wanted to at least get something up for people to see. If you are thinking of joining Costar, DONT. There are plenty of other commercial real estate databases out there.
