Realtors Share Data

Rather than maintaining separate databases of properties for sale, residential real estate brokers in the United States place their listings in a common database. The multiple listing service (MLS) database is a centralized storehouse of property information for Realtors, property appraisers and other licensed professionals. Tampa Realtors subscribe to the the largest largest MLS  in Florida, the My Florida Regional MLS, which has approximately 30,000 subscribers who enter and search over 100,000 property listings. While the public cannot access the MLS directly, a subset of the data is made available to members to and public websites such as,, Zillow, Trulia, Google, Yahoo, etc.

Realtors Share With The Public

Realtors can choose to publish their MLS listings to public websites using a protocol called Internet Data Exchange (IDX). Websites such as Trulia, Zillow, Google and others receive IDX data feeds from local Multiple Listing Services. IDX also allows Tampa Bay Realtors publish information about all current listings on their own websites such as, not just their own properties. (see: What is IDX? )

Realtors Share Commissions

MLSThe Multiple Listing Service also allows real estate brokers to establish contractual offers of compensation (guaranteed commissions) among cooperating brokers, see How Realtors Are Paid. Tampa Bay Realtor listings include a guaranteed commission to any participating member who brings a contract, usually expressed as a percentage of sale price. Brokers and agents publish, search and share information about homes for sale in Tampa with others members who may represent potential buyers. The MLS allows all members to sell each other’s listings. The My Florida Regional MLS database is used by Tampa Realtors, appraisers and other members to facilitate orderly data compilation, correlation and dissemination of housing information.
