What requirement must a representative always fulfill during sales presentations?

A representative is required to disclose all costs involved during sales presentations to ensure transparency and maintain ethical standards in real estate practices, particularly in timeshare sales. This requirement protects consumers by providing them with a complete understanding of their financial obligations, including any fees, maintenance costs, and potential increases in the future. Full disclosure helps buyers make informed decisions about their investment and prevents misunderstandings that could lead to disputes later on.

Using persuasive language or highlighting ownership benefits may enhance the sales presentation, but they do not equate to the legal obligation of cost disclosure. Additionally, while understanding property transactions is crucial for a salesperson, it is not a specific requirement that must be consistently fulfilled during every sales presentation. Therefore, transparency regarding costs is the most critical requirement in protecting consumer rights and fostering trust in the transaction process.
