Why Should You List Your Home on MLS? MLS which stands for multiple listing services is sharing of home information among real estate professionals. Listing brokers enter information about the home for sale and offer commission with a broker who brings a buyer. MLS is online software that contains all the specifics of a home, like address, square footage, number of rooms, upgrades, school districts and types of financing seller would prefer. It also includes plenty of photographs of the home or sometimes links to a virtual tour.
