The Real Estate Broker who represents the seller. The Listing Agent in most instances – but not all! – lists the property on the Multiple Listing Service. There are a handful of real estate firms, like Houses.Direct in Seattle, that “list” properties on other web sites but not the MLS. By skipping the MLS, these brokers don’t have to offer a selling office commission so they save 3% - on top of whatever they save by hiring someone other than a traditional listing agent.
