Which of these must be included on salesperson Smith's business cards?

The inclusion of the brokerage address and phone number on salesperson Smith's business cards is essential for regulatory compliance and professional representation. In real estate practice, particularly in West Virginia, it is required that salespersons identify themselves as associated with a licensed real estate brokerage. This ensures transparency for clients and other professionals in the industry, as well as providing a clear point of contact through the brokerage.

Having the brokerage's information prominently displayed also reinforces the business relationship and helps to establish the credibility of the salesperson. It allows clients to easily reach the brokerage for any inquiries or to address potential issues that may arise during a transaction. This requirement is in place to maintain professionalism and trust within the marketplace.

Other elements, such as personal addresses or marketing slogans, might not be essential or may even contravene certain ethical standards, depending on the regulations governing real estate practices. Focusing on the brokerage's details ensures that the primary business entity’s information is accessible to clients and partners alike, facilitating smoother transactions and fostering professional integrity.
