A Multiple Listing Service (MLS) is a database used by real estate professionals to share information about properties for sale. It allows agents to list homes, view listings from other agents, and access detailed information about properties, including prices, features, and photos. This system helps streamline the buying and selling process by providing a centralized platform for real estate transactions. MLSs are typically regional and operated by local or state real estate associations. They enhance cooperation among agents, enabling them to work together to find buyers for sellers' properties. This collaboration ultimately benefits consumers by increasing market exposure and improving access to available homes.
