Multiple Listing Services (MARIS)

The Multiple Listing Service (MLS) is a tool to help listing brokers find cooperative brokers working with buyers to help sell their clients' homes. It also provides tools to help market listings to serve buyer and seller clients better. MLSs are a powerful force for competition.

To learn more about the benefits of the MLS, visit competition.realtor. Membership with a REALTOR® association is required to purchase MLS services.
