MLS simply stands for “Multiple Listing Service.” When real estate agents are members of the MLS, they can be a part of any aspect of a home purchase or sale. In other words, even if a property is listed with Company A, it may be sold by an agent working at Company B. So if you, as the seller, list your property with a real estate agent who is a member of MLS, you’ll give yourself the extra benefit of having more agents aware of your listing.
