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 property information, 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 properties and vice versa. This collaboration ultimately benefits sellers and buyers by increasing market exposure and options.
