Multiple Listing Service (MLS)

A Multiple Listing Service (MLS) is a cooperative database used by real estate professionals to list and share properties for sale within a specific region. Created and maintained by local brokers and agents, MLSs consolidate detailed, up-to-date listing information—making it easier for agents to find matches for buyers and to market sellers’ properties broadly.

Key takeaways

  • MLS is a broker-managed database that centralizes property listings for a region.
  • Access is generally limited to licensed real estate agents and brokers who belong to the MLS and pay membership dues.
  • MLS listings include rich details (photos, square footage, features, price, days on market) and tend to be the most accurate source for current listings.
  • Some public websites aggregate MLS data, but agents using the MLS have access to the most complete and timely information.

How MLS works

  • Local real estate brokers collaborate to populate and update a regional database of listings.
  • Listings are posted by member brokers and typically include price, property details, photos, showing instructions, and status updates.
  • Brokers use the MLS to search all participating agents’ listings, coordinate showings, and negotiate cooperative compensation.
  • Many MLSs are online systems; historically they began as printed catalogs.

What information is included in an MLS listing

Common MLS fields:
* Listing price and status (active, pending, sold)
* Property address and location details
* Square footage, lot size, room counts
* Photos and sometimes virtual tours
* Property features and amenities
* Days on market and listing history
* Showing instructions and contact information for the listing agent
* Property type or sale type (e.g., foreclosure, short sale)

Accessing the MLS

  1. Work with a licensed real estate agent or broker who is a member of the local MLS.
  2. Agents or brokerages pay membership and access fees to their MLS organization.
  3. Agents can provide clients with listing details or access via the agent’s website or client portals.
  4. For sellers unwilling to hire a full-service agent, some markets offer flat-fee MLS listing services that place a property on the MLS for a set price.

Fees and membership

  • MLS organizations set their own fee structures for broker members; fees vary widely by region.
  • The MLS typically charges brokers and agents, not the general public.
  • Commission arrangements between buyer and seller brokers are negotiated through the MLS listing.

MLS number and related identifiers

  • An MLS number is a unique identifier assigned to each property listing, used to track and reference listings quickly.
  • Separately, NMLS numbers identify mortgage loan officers through the Nationwide Multistate Licensing System; these are not MLS identifiers.

Why MLS still matters

  • Consolidates fragmented listing information into a single searchable system for participating brokers.
  • Improves market transparency and efficiency for buyers, sellers, and agents.
  • Levels the playing field for small and large brokerages by sharing exposure across participants.
  • Provides the most current and complete data compared with many public aggregator sites.

Frequently asked questions

Do I need a real estate license to access MLS?
* Direct access to the MLS is generally restricted to licensed agents and brokers. Buyers and sellers typically view MLS information through an agent or public-facing websites powered by MLS feeds.

How are MLS fees handled?
* Fees are charged to brokers and agents by the local MLS organization. Public access is usually free via broker websites or national aggregators, but those sites may lag behind the MLS.

Can I list my home on the MLS myself?
* Some areas allow flat-fee MLS listings so a homeowner can pay to have their property entered into the MLS without hiring a traditional listing agent. Availability and rules vary by market.

Conclusion

The MLS is a foundational tool in residential real estate: a cooperative, broker-run database that centralizes detailed listing data, streamlines marketing and search efforts, and supports efficient transactions. While consumer-facing websites make property browsing easy, working with an agent who uses the MLS ensures access to the most accurate and timely information.
