The Multiple Listing Service (MLS) is a private resource that enables realtors to list properties available for sale. In recent times, the public has gained some access to the information on sites like LocateHomesFlorida.com, realtor.com, MSN, HomeAdvisor, and others. When a property is sold and the deal is closed, the selling price is posted to the listing in MLS. This becomes a valuable database on past sales, containing much more information than public records. This service is available only to Northeast Florida real estate agents who are members of the local Multiple Listing Service. Your agent will be able to equip you with this data to assist you in making the best offer price.
