20 Custom MLS Software Development Companies to Transform Your Platform

What is Real Estate Multiple Listing Service (MLS) Software?

A Multiple Listing Service (MLS) is a database used by real estate professionals to share information about properties for sale. Real estate brokers and agents add listings to this database, which lets them work together, manage, and search properties online. 

Agents, brokers, and even clients can access and update property information in real time. Also, MLS allows users to see all available listings and filter them by criteria like location, price, amenities, and more.

How Does MLS Work?

An MLS is usually a private database where agents and brokers in a specific region share property listings. Here’s how it happens:

• Licensed real estate agents upload detailed information and photos for the properties they’re selling, including the property’s features (like number of bedrooms, bathrooms, square footage), its price, and its status (e.g., active or pending).
• Once listed, the property information becomes accessible to other agents and brokers who are members of that regional MLS.
• Listings are updated regularly, so the database stays current.
• Other agents use the MLS to search for listings that match their buyers’ needs and arrange showings.

Some properties aren’t listed in the MLS. This usually happens when the seller chooses not to use an agent or keeps the property private. Common examples include:

• For Sale by Owner (FSBO): Homes sold without using an agent usually don’t get listed in MLS.
• Pocket Listings: Exclusive or off-market properties kept private by the seller, sometimes to wait until they find a specific buyer or for privacy reasons.

Overall, an MLS platform is a digital tool that connects buyers, sellers, and agents. It makes the real estate business processes more convenient and faster for everyone involved.

Why Invest in MLS Development?

97% of homebuyers use the Internet to search for homes, and 51% end up buying a home they discovered online. Basically, MLS helps real estate businesses reach more buyers and get a better market presence. Some benefits MLSs bring to real estate stakeholders:

• Real Estate Brokerages and Agencies: Easier collaboration between agents, faster property updates, wider reach to potential buyers, and fewer listing errors.
• MLS Associations or Boards: Standardized property data across the region, better member support, and easier management of listings.
• Investors or Startups: Faster market entry, access to aggregated property data, and potential for recurring revenue from subscription or service models.
