RUNNING CASE STUDIES Community Board of Realtors The real estate business relies on an extensive amount of information used in the buying and selling of real prop- erty. Most communities of real estate agents and brokers have formed cooperative organizations to help consoli- date and distribute information on the real estate pro- fession, real estate trends, properties in the community, historical records of property sales, and current listings of properties for sale. These organizations are usually referred to as the Community Board of Realtors. Research your local Community Board of Real- tors to answer these questions: 1. Who are the stakeholders for the issues related to real estate in your community, and what are their main interests? 2. What types of information does the board col- lect and make available to its members and to the community? 3. Research the real estate industry in at least two countries other than the United States.
