The MLS or Multiple Listing Service is an online database and a marketplace of available home listings operated by REALTORS® to help home sellers and buyers complete their transactions at ease. With over 800 MLSs in the country, real estate brokers can find homes for sale, view home data, and interact with other realtors or agents. Most of these local MLS will also help distribute your property to Zillow, Trulia, Redfin, and other brokerages/portals. On the other hand, a Flat Fee MLS is an alternative route for home sellers to list their home on MLS without having to pay the typical full commission (5 to 6% of sales price). Using a Flat Fee MS service is to collaborate with an agent for a pre-set amount of money to list your home on the local MLS with valuable services to market your home faster. Most For Sale By Owner sellers opt for this choice since they want to sell their house without a realtor, but still want to list their home on the MLS.
