Caroline Gau, Broker with Baird & Warner Glenbrook advises in her weekly series Week 13: 17 things I’ve learned in business in 17 years. Give back to the community. I am grateful for the opportunities to live and work in Northbrook, IL. It makes me feel good to volunteer, sponsor and host community events throughout the year. Today I am going to the Joliet Board of Realtors to hear an arbitration dispute. Instead of a court, in our world we have peers listen to both sides to decide a finding. Not everyone understands how realtors get paid. What do you do if two agents show the same house? Who gets paid? This is what we are determining today.
