The MLS (Multiple Listing Service) is a cooperative listing service among licensed real estate agents and brokers. Members of the MLS input detailed information regarding properties available for sale into a database that is distributed to all participants in the MLS. All members of the MLS have a right to show/sell an advertised property and are promised a commission should they present an offer that results in the successful sale of an advertised property. The vast majority of home sales are made through participation in the MLS.
