Common MLS Technologies and Their Implications for Realtors

MLS are, in essence, technology companies that are often run by AORs or BORs in a geographical area. There are over 500 MLS across the US and this number goes up and down as more MLS emerge and older ones merge.  The main function of an MLS is to provide a reliable and updated listings feed. They do this through IDX technology. However, MLS offer other solutions and MLS technologies as well. These solutions are designed and provided to ease real estate services, both for clients and realtors. 

In this article, we will have a look at some of the most common technologies offered by MLS. Your MLS may not offer all of these, so please contact them for more information:
