The Multiple Listing Service (MLS) is a service that allows potential buyers and sellers to research properties available within a specific area. This service is available to all local participating agents within the specific area and is available on the internet for web browsing. It allows individuals searching for properties for sale to enter specific search criteria and view listings that reflect their interests. It also serves those wishing to sell a property as it provides listing prices and individuals may see what comparable properties are being marketed in the area.
