Which of the following must be disclosed by time-share agents when advertising?

In advertising for time-share properties, it is essential for agents to disclose that the advertisement pertains specifically to time-share estates. This is crucial because potential buyers need to be fully aware that they are not purchasing traditional real estate but rather a shared ownership interest in a property. By clearly stating that the ad is for selling time-share estates, time-share agents help ensure transparency and allow consumers to make more informed decisions regarding their investments.

This disclosure also protects consumers from potential misunderstandings about what they are buying, as time-share ownership operates differently from standard property ownership, including factors such as shared use and associated obligations. Providing this clarity is a vital part of maintaining ethical advertising practices within real estate.

The other options may include relevant information but are not mandated disclosures in the same way. While location and maintenance fees are important for marketing, they do not carry the same responsibility of transparency regarding the nature of the ownership being sold, which is why the stated disclosure is paramount.
