What is the "MLS" in real estate?

The correct answer is Multiple Listing Service. In real estate, the MLS is a vital tool that acts as a comprehensive database where real estate agents can share information about properties for sale. This service allows agents to collaborate and access a wide array of listings, which benefits both sellers and buyers. Sellers gain more exposure for their properties as all participating agents can list them, while buyers have a larger selection of options due to this shared resource.

The term "Market Listing System" does not appropriately capture the function or the established terminology used in the industry. "Mortgage Loan System" inaccurately suggests a focus on financing rather than property listings. Lastly, "Minor Listing Service" is not a recognized term in real estate and misrepresents the purpose and nature of the MLS.
