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, condos, and other real estate, making it easier for buyers to find available properties. The MLS includes details like prices, locations, and features, helping agents collaborate and serve their clients effectively. MLS systems are typically regional, meaning they cover specific geographic areas. They are essential tools for real estate agents, as they provide access to a wide range of listings and market data. This helps ensure that buyers and sellers receive accurate and up-to-date information about the real estate market.
