Which action may fall outside of TREC's authority regarding advertising practices?

The correct answer highlights an area where TREC's authority is limited. The Texas Real Estate Commission (TREC) is responsible for enforcing laws and regulations related to real estate practices in Texas, including advertising. However, certain decisions related to the aesthetic elements of advertisements, such as the appearance of actors or models in an ad campaign, typically fall outside of TREC's regulatory scope. This aspect is often left to industry standards and the individual discretion of real estate professionals and advertising agencies rather than being governed by formal regulations enforced by TREC.

On the other hand, requiring disclosure of fees, mandating the appropriate use of property images, and regulating false advertising claims all fall within TREC's mandate. These actions serve to ensure that consumers are protected from deceptive practices and that advertisements provide clear and accurate information. Thus, TREC actively engages in these areas to promote fair and ethical business conduct within the Texas real estate industry.
