The controversy surrounding the manner in which listing aggregators (such as realtor.com or Zillow) display the names of the listing broker, the listing agent and the advertising agent has returned to the forefront. In the last couple of weeks the California Regional MLS, the nations largest MLS, with over 108K subscribers, has instituted a new rule 12.16.5 requiring that “a) Who is the Listing Agent &, Broker b) Who is the Advertising Broker and c) How to contact the Listing Agent or Broker.” Click on the link above to read the complete rule.
