Final answer:
The correct answer is that an ad must include the assessed value of the property, which is not actually a requirement in real estate advertising. Typically, ads must include the broker's name, licensing information, and be reviewed by the principal broker.
Step-by-step explanation:
The rule that is not a requirement for real estate advertising is that 'the ad must state the assessed value of the property being sold'. Real estate advertising laws and regulations primarily focus on the accuracy of the information provided and the disclosure of the broker's credentials.
For instance, ads must frequently include the broker's name and a statement indicating that the broker is licensed, especially in certain jurisdictions like Oregon. In addition, it is common practice that the principal broker reviews all ads to ensure compliance with legal standards and company policy.
It is not a requirement to state the assessed property value in an advertisement, as the value can be subject to change and might not necessarily reflect current market conditions.
