Multiple listing service
A multiple listing service is the local database US brokerages use to share listings with other member firms. It is not a public portal like Rightmove, and it is not a national website a British agent can simply join.
Also called MLS.
Who sees it
Members of that MLS, and the public sites those members syndicate to, such as the brokerage’s own site and large portals. Rules on remarks, photos and when a listing must be entered are set by that MLS. KeyAccess does not submit listings to an MLS.
British comparison
UK agents upload to Rightmove, Zoopla or OnTheMarket, usually from their CRM. Those are advertising portals. An MLS is a broker-cooperation system. Do not describe Rightmove as “the MLS”.
