When buying a home, the Multiple Listing Service (MLS) can serve as a valuable tool. It’s so widely used that based on a recent National Association of REALTORS® (NAR) report, 86% of sellers list their homes on the Multiple Listing Service (MLS). Let’s explore how you can harness this popular tool for your own home search.

What Is A Multiple Listing Service (MLS)?

An MLS is an online database that lists homes for sale in a specific area. However, the listings aren’t available to the general public – only real estate professionals have access to this information.

Importantly, an MLS is targeted to a specific location. Based on a recent Real Estate Standards Organization report, approximately 560 different MLS systems exist within the U.S.

How Does A Multiple Listing Service Work?

As we mentioned, only licensed real estate agents and REALTORS® can access an MLS.

The collection of properties on the local MLS is built by real estate agents who have access to the service. When a real estate agent starts working with a home seller, one of their first steps is often to create a listing on the MLS.

From the buyer’s side, your real estate agent can track down homes available to buy in your target area. Plus, they can even filter the search only to show you homes that might fit your needs.

When the real estate agent spots a home that suits your interest, they will pass the pertinent information along to you. Importantly, listings on the MLS tend to have an extensive amount of information about the given property. With access to so much information, buyers have a chance to rule out properties based on their preferences before making time to tour the property in person.

Homebuyers and sellers can’t view the properties listed on their local MLS. Instead, buyers and sellers must find online home listings through public portals that pull information from multiple listing services across the country.

What Kind Of Information Can You Find On An MLS Listing?

The information included in an MLS listing may vary slightly from listing to listing. But, in general, you will see some of the following information in a real estate listing:

  • Total square footage of a home
  • Note of any recent renovations
  • The age of standard home appliances, like the hot water heater
  • A description of any special features
  • The number of bedrooms and bathrooms
  • Photos of the home
  • The number of days the home has been listed
  • The HOA fee, if applicable

As a home buyer, all of this information can help you narrow your search. For example, just determining how many bedrooms you want to have in a home can help you rule out any houses that seem too large or too small. Additionally, the photos provided will help you decide whether or not it’s worth taking a look in person.

What Are The Pros And Cons Of A Multiple Listing Service For Home Buyers?

Every tool has advantages and disadvantages to consider. Here are some things to consider about using the Multiple Listing Service as a home buyer.

Pros Of Using The MLS

  • Comprehensive listings: The listings found within the MLS usually have a large amount of information. You and your real estate agent can work with this information to determine whether you want to pursue buying the property.
  • Timely information: Real estate agents tasked with selling a home typically list it on the MLS first. In a hot market, access to this information immediately can help you close on a home.
  • Includes multiple types of listings: You can scope out listings from a wide range of real estate professionals in your local area.
  • Move forward quickly: Homes listed on the MLS tend to sell faster. As the buyer, acting quickly can help you finalize your home buying journey faster.

Cons Of Using The MLS

  • Limited access: The MLS isn’t publicly available, which means you’ll need to work with a real estate agent to see any listings.
  • May not include all local listings: Some listings won’t make it onto the MLS. A few types of listings that aren’t included on the MLS include pocket listings and listings that are for sale by owner (FSBO).
  • Mistakes can happen: The listing agent might make a mistake on the original listing. For example, listing 2 bedrooms instead of 3. While a major mistake like this doesn’t happen often, other mistaken information might cause you to skip on looking at your would-be dream home.
  • Competition: When a home hits the MLS, it can start a frenzy of activity. If you are trying to buy in a hot market, this means you could face some steep competition.
