Ken lists a property for sale. What must ads for this property include if the client wishes to advertise as well?

Including the listing company's name in advertisements for a property is important because it ensures that the public is aware of the professional entity representing the property. This requirement serves several purposes, including enhancing transparency in real estate transactions and allowing potential buyers to identify who to contact for further information or to schedule a viewing.

The listing company's name also maintains a standard of professionalism and ethical practice within the real estate industry, as it helps to prevent confusion regarding the representation of the property. Advertisements that omit the name of the listing company can mislead potential buyers and create issues with attribution and accountability in the transaction process.

The other options, while they might be useful information to potential buyers, do not carry the same requirement under real estate advertising laws and standards. Thus, focusing on the inclusion of the listing company's name is essential for compliance and professionalism in real estate marketing.
