Which statement must be included in a licensee's advertisement?

The requirement for a licensee's advertisement to include a statement that the ad is made by a brokerage company is crucial for transparency and consumer protection. This statement helps clarify that the advertisement represents a professional real estate service, ensuring that consumers understand they are dealing with a licensed entity. It establishes credibility and accountability in the transaction process, allowing potential clients to identify the source of the advertisement and trust in the legitimacy of the offerings presented.

Other options do not align with the fundamental requirements for advertising in real estate. Including the licensee's commission structure might not be necessary in all advertisements, as commission details can vary based on negotiations and are not typically disclosed upfront. Listing all properties available for sale is impractical and could misrepresent the dynamics of a rapidly changing market. Similarly, mentioning the date of license issuance does not contribute to the advertisement's purpose and may not provide relevant information for potential clients.
