A real estate salesperson working for a listing must always disclose:

In the context of real estate transactions, a salesperson has an obligation to engage in full disclosure to maintain transparency and fairness. This is particularly important in ensuring that both parties are informed about any significant aspects that could influence the transaction.

The correct answer emphasizes the necessity for the salesperson to disclose all material facts to both the seller and the buyer. Material facts are information that could affect the decision-making process of either party, such as issues regarding the property's condition, title problems, or zoning restrictions. By disclosing these facts to both parties, the salesperson upholds the ethical standards of practice and ensures compliance with legal expectations, fostering trust and reducing the risk of future disputes.

The focus on both the seller and buyer is crucial because it helps to create a balanced and fair negotiation environment. This approach allows both sides to make informed decisions based on the same information, minimizing misunderstandings that could lead to legal ramifications down the line.

While other options limit the disclosure to only one party or suggest that the salesperson does not need to disclose some facts entirely, they fail to recognize the comprehensive duty that a real estate professional has in fostering transparency and ethical practice within transactions.
