The MLS or mostly known as Multiple Listing Service is a local database of available homes for sale. It’s a portal only accessible by licensed real estate brokers and agents who can list your property, search for user’s data, or find home buyers. A Flat Fee MLS, on the other hand, is a real estate service that can market your home for an “Entry Only” service with a pre-set price to list your property on the MLS. When you sell your house as a For Sale By Owner, a Flat Fee MLS is a perfect option that will save you at least half the traditional full commission. Instead of the 5 to 6% agent commission, you only need to pay a discounted price to list your home—or choose a Flat Fee package that offers other real estate services. Once you select for a flat fee, you can list your property on the local MLS and get distributed to Realtor.com, Zillow, Trulia, Redfin, and other real estate portals.
