A Multiple Listing Service (MLS) is a suite of services that:
1. Enables brokers to establish contractual offers of compensation (among brokers);
2. Facilitates cooperation with other broker participants;
3. Accumulates and disseminates information to enable appraisals;
4. Is a facility for the orderly correlation and dissemination of listing information to better serve broker's clients, customers and the public.
A multiple listing service's database and software is used by real estate brokers representing sellers under a listing contract to widely share information about properties with real estate brokers who may represent potential buyers or wish to cooperate with a seller's broker in finding a buyer for the property. The listing data stored in a multiple listing service's database is the proprietary information of the broker who has obtained a listing agreement with a property's seller.
Last year (2016) 87.3% of all homes sold in Marin were MLS Sales
