The results show that nearly half of the participating real estate companies continue to apply the old standard rate (5%), despite the withdrawal of AAR’s guidelines. Since approximately 40% of the contacted real estate companies responded to the survey, it cannot be ruled out that this behavior occurs more frequently in practice than the results suggest.

In addition, 74% of the participating real estate companies apply a fixed 50/50 commission split. When many real estate companies use the same split, this may indicate coordination (concerted market behavior). According to competition rules, real estate comapanies must set their commission rates and splits independently and are not allowed to make agreements with each other.
