What You Should Know About the Multiple Listing Service (MLS)?

SOURCE: Windermere

In the process of buying or selling a home, you’ll frequently come across the term “MLS.” The Multiple Listing Service (MLS) is a group of regional databases of homes for sale accessible only to real estate agents and brokers. Their ability to access the MLS makes it easier for buyers to find the right home and for sellers to market their listings.

What is the Multiple Listing Service (MLS)?

The purpose of an MLS is to facilitate real estate transactions by connecting real estate agents and making it easy for them to share information about active listings and sold home data. For buyers and sellers, your agent’s access to the MLS means you’ll be connected to the largest network of homes and listing information on the market.

There are over 500 independent MLSs across the United States, with each MLS showing the homes for sale in a particular geographic region. Listing agents add their clients’ listings to the database—providing photos and detailed information about the property—so buyer’s agents can show them to their clients. The MLS allows for customizable searches, which agents use to easily identify the homes that match their clients’ criteria. The vast amount of historical data available on the MLS is what your agent will use to conduct their Comparative Market Analysis (CMA) to competitively price your home. The listing data in the MLS is fed to real estate brokerage websites, such as Windermere.com, so that buyers can search for homes on their own as well.

Benefits of the Multiple Listing Service (MLS)

Selling a home is a numbers game. The more potential buyers you can reach, the more likely you are to find the right buyer in a timely manner. After your agent conducts their CMA to determine the value of your home, they’ll upload the listing to the MLS. Here, they can add additional information beyond what you would find in a typical listing description, such as showing times, contact information, and more. The MLS provides maximum visibility for sellers by connecting them to buyer’s agents who are actively searching for listings. In today’s market, many MLS platforms offer mobile-friendly tools and agent apps, making it even easier to track showing requests, market updates, and search results on the go. Some even use AI to help agents identify pricing trends or recommend homes that match specific client needs.

The MLS has also helped to make the industry more equitable. Many MLSs enforce policies that promote fair and equitable access to listing data. This includes rules that require agents to submit a listing to the MLS within 24 hours of public marketing, along with principles from the Fair Display Guidelines, which aim to ensure that property listings are represented transparently and are easily accessible. Small real estate brokerages have access to the same MLS info as large companies, putting everyone on a level playing field.

For buyers, the MLS means greater transparency. Agents can set up auto-alerts based on your criteria and ensure you’re seeing listings as soon as they go live. Because the MLS is updated in real-time by licensed agents, it’s often more reliable than national search portals when it comes to availability and details.

What is an MLS number?

An MLS number is a unique code for each home listed on the market. It makes it easier for agents to communicate regarding a specific property. This number also helps agents quickly pull up detailed reports, schedule showings, and share links directly with their clients. If you ever have a question about a home you’ve seen, providing the MLS number ensures your agent can locate it fast.
