A private database maintained by real estate brokers that aggregates property listings, enabling cooperative selling and providing the most comprehensive and accurate source of for-sale homes.
The Multiple Listing Service (MLS) is a private, broker-operated database that real estate agents use to share property listings with one another and to facilitate cooperative compensation — meaning the listing agent (representing the seller) and the buyer's agent can share the commission when the buyer's agent brings a successful purchaser. There are approximately 580 regional MLS systems in the United States, each covering a specific geographic area, and membership is generally restricted to licensed real estate agents who join through their local Association of Realtors or MLS organization.
When a home is listed with a real estate agent, its information is entered into the MLS within a required timeframe (usually within 24 to 72 hours of listing agreement), making it immediately visible to all member agents and their buyer clients. The MLS contains far more detail than public consumer sites: exact days on market, showing instructions, commission splits, previous list price history, and agent-to-agent notes that do not appear on consumer-facing platforms like Zillow or Realtor.com, which are actually fed by MLS data.
For buyers, access to MLS data through a licensed agent provides more accurate and more timely information than public portals, which can have listing lags of 24 to 72 hours and often contain outdated or inaccurate data on sold homes. For sellers, MLS listing ensures maximum professional exposure — all buyer's agents in the market can see and show the property, dramatically increasing competition.
The 2024 NAR commission settlement changed how buyer-agent compensation is disclosed and negotiated, requiring buyer representation agreements to specify compensation upfront and removing the requirement that sellers offer buyer-agent compensation through the MLS. This is reshaping how agents operate and how buyers and sellers negotiate fees.
The MLS remains the most complete and authoritative source of property data in most U.S. markets, and access to it is one of the core value propositions of working with a licensed real estate professional. Buyers who attempt to search exclusively through consumer apps may see incomplete inventory, miss newly listed properties, or rely on stale sold data when evaluating offers.
Understanding how the MLS works — and what data your agent is using — also helps you evaluate the quality of your agent's pricing advice. Agents who pull accurate, comprehensive comparable sales data from the MLS provide far more reliable market analysis than anyone working from consumer platforms alone. For sellers, your listing strategy, including how your home is presented in the MLS, directly determines how much buyer traffic and competition you generate.
