About @properties

Established in 2000, @properties was built around a simple but elusive concept: provide brokers and clients with the highest level of service in the industry through cutting-edge sales and marketing programs and a culture that values innovation, relationships, and a strong local focus.

In less than ten years, @properties became the #1 brokerage firm in Chicago. Today, @properties is one of the top eleven residential brokers in the U.S. by sales volume and the second largest brokerage firm on Chicago’s North Shore.

As a locally-owned company, @properties is deeply committed to supporting the communities and clients we serve. We are constantly evolving, but we remain focused on that one simple idea behind our founding.
