Both the office park and the office of North Shore-Barring Association of Realtors are a bit confusing to get to. 450 Skokie Boulevard is an office park located behind 400 Skokie Boulevard. The Association of Realtors is in building 1200 at the northernmost side of the office park with an entrance at the back of the building. It has been at this location since 2008. Members of the NSBAR are a group of diverse realtors serving the Chicago-land area. The organization also offers classes and educational events for individuals seeking pre-licensing courses and guidance toward becoming real estate brokers.
