A Multiple Listing Service, Multiple Listing System or widely known as MLS, is an online database for local or regional property listings. It’s an exclusive system operated by REALTORS® that will also help feed homes for sale to the following sites such as Zillow, Realtor.com, Trulia, Redfin, and more. You can only access the online database or MLS through the help of licensed real estate brokers or agents who have paid a membership fee to get exclusive access to the local MLS. In order to save thousands of commission, most homeowners who sell a house without a realtor or For Sale By Owner pick a Flat Fee MLS program for its promising benefits. Through a Flat Fee MLS package, you gain maximum exposure in the market via local MLS and can still take care of your home sale completely on your own. Also, some FSBO companies offer custom-tailored packages to your preferences.
