What Is The Multiple Listing Service In Real Estate?

The success of a real estate market depends on the cooperation of the professionals working within it. Buyers need a seller; sellers need a buyer. The MLS maximizes the potential for real estate brokers and agents to help these two groups find each other.

The MLS, or multiple listing service, is a tool real estate professionals use to share information with each other about homes on the market.

What Is A Multiple Listing Service?

A multiple listing service is a database of all homes currently for sale in a given area. As the name suggests, this database is full of home listings, which provide agents and their clients with useful information about each home on the market.

While it’s often referred to as “the MLS,” making it sound like a single entity, it’s actually a network of local databases for areas around the country. There isn’t one single, overarching MLS.

Local MLS databases are made up of real estate brokers who operate in the area. Real estate firms will list for-sale properties they represent on the local MLS, where buyer’s agents can find them.

The MLS isn’t publicly available; if you want to access the MLS in your area, you’ll need to have a real estate license.

How Does The Multiple Listing Service Work?

An MLS covers a specific area. The brokers who participate in that MLS list the properties they’re selling within that area for other real estate professionals to see and market to their clients.

If a broker wants to list or view homes in an area that isn’t covered by the MLS they’re currently part of, they’ll need to join the MLS for that area as well. So, it’s possible and sometimes necessary for brokers to participate in multiple MLS databases.

There are just under 600 MLS databases across the country. The number of them has trended downward over the years as neighboring databases come together to form larger, regional ones.

When an agent or broker joins an MLS, they’ll need to pay for that access. Each one sets its own prices, fee schedules and rules for using the database. MLS access cost will vary, but can cost several hundred dollars each year, in addition to a one-time registration fee.

How The MLS Works For Buyers And Sellers

How does the MLS work as it pertains to home buyers and sellers? Let’s take a look at how the process typically works.

For Sellers

When a homeowner wants to sell their property, they’ll typically enlist the help of a real estate agent (unless they’re going the for sale by owner (FSBO) route). The agent will take pictures of the home and gather some basic information about the property. They’ll also use real estate comps to compare the home to other similar homes that have recently sold to come up with a list price.

Once they have all this information, they’ll upload it into the MLS as a listing.

MLS listings include pretty much the same information that you’ll find in a publicly available listing, such as basic property information (square footage, number of bedrooms and bathrooms, etc.), photos and a short description of the property that highlights some of its most desirable features.

However, MLS listings will also typically include private agent remarks meant only for other agents. This is to protect the privacy and safety of the seller. These remarks can include things like seller contact information, showing instructions (such as best time for showings, information about pets in the home, gate codes, etc.), seller disclosures or homeowners association (HOA) regulations.

Once a home is listed on the MLS, it will be exposed to all other agents and brokers who use that MLS, greatly increasing its visibility among potential buyers.

For Buyers

When a home buyer works with an agent to buy a house, the agent will discuss with the buyer what type of home they’re looking for. They’ll ask about their ideal price range, what size home they need, what features are important to them and where they’d like to live.

Then, the buyer’s agent will use these criteria to search for a home in the MLS that suits the buyer’s needs. When they find homes the buyer is interested in, they can use the information in the MLS to schedule showings or make buyers aware of upcoming open houses.

Perks Of Using A Multiple Listing Service

The MLS is beneficial to everyone who participates in it. From a business perspective, working together to form an MLS means that real estate professionals can offer their selling clients maximum exposure, while ensuring that buying clients get a complete view of what’s on the housing market.

It also ensures that the industry remains competitive and equitable, since smaller firms have access to the same listings as larger ones.

For sellers, having your home listed on the MLS can help your home sell faster and for more money. For buyers, working with an agent who utilizes the MLS means you can be confident you’re getting a full picture of what’s for sale in your area.

Multiple Listing Service FAQs

What is an MLS listing?

An MLS listing is similar to any other standard public real estate listing except for a few extra additions. A typical MLS listing will include all the basic information an agent or their buyer would need to know about a home: price, address, property type, square footage, number of bedrooms and bathrooms, information about utilities and other basic features.

MLS listings also include photos of the home’s interior and exterior and any notes the listing agent made about the property. This can also include private remarks meant only for other agents. These remarks could include things like showing instructions or information on how to access the property.

How can I get access to the MLS?

To be able to view and use an MLS, you’ll need a real estate license. Real estate agents must work under a broker who participates in the MLS they want access to.

In most cases, MLSs are only accessible by REALTORS®, who are members of the National Association of REALTORS® (NAR).

MLS databases require users to pay regular dues for continued access.

How do I view homes on the MLS?

If you’re not a licensed real estate professional, you likely won’t be able to view homes directly on the MLS.

However, many real estate firms feature MLS feeds on their websites to advertise the properties they’re selling. There are also a variety of online listing sites that allow consumers to easily access much of the same information you’d find in an MLS listing.

What is the main value of the MLS for sellers?

When a seller has their home listed on the MLS, their property will be visible to every other agent and broker who participates in that MLS, significantly boosting their ability to find a buyer.

In fact, access to the MLS is one of the main benefits for sellers who use an agent. Not being able to list their home on the MLS can be a significant disadvantage for FSBO sellers.

Are online listing sites different from MLSs?

Online listing sites (think Zillow and REALTOR®.com) aren’t MLS databases, though they often pull their data (with permission) from various MLS feeds across the country. These sites aggregate those listings and make them publicly available.
