Real estate brokers don't have the power they used to before the Internet. Today, buyers and sellers can use the Internet to view listings and perform other tasks that used to be exclusively performed by a broker.
Brokers have one thing that everyone wants, which is direct access to the Multiple Listings Service (MLS). The MLS is a database that stores information about properties for sale. Furthermore, the MLS is a regional joint venture of real estate brokers affiliated with the National Association of Realtors. You cannot access the MLS unless you are a licensed member of your local MLS service. Many real estate companies put an MLS-like database on their websites for homebuyers to look through, but it is not the same thing. There is not a more comprehensive list. Having the MLS at their fingertips makes brokers informative and powerful. Which is one of the reasons that a vast number of property sellers use brokers.
