Which of the following information should not be revealed when a broker is acting as a dual agent in a transaction?

When a broker acts as a dual agent in a transaction, they must navigate the complexities of representing both the buyer and the seller. Dual agency can create inherent conflicts of interest, requiring the broker to maintain a delicate balance of confidentiality between the parties.

Revealing that the buyer will pay more than what they are currently offering is information that should not be disclosed. This information could significantly disadvantage the seller by potentially discouraging them from entertaining other offers or negotiating strategies that could benefit them. Such a revelation could undermine the seller's negotiation position and leverage. Maintaining the confidentiality of the buyer's willingness to offer more is crucial to ensuring the transaction remains fair and equitable for both parties.

In contrast, the other options involve details that are part of normal transparency in negotiations. For instance, understanding the buyer's financial capabilities can help the seller make informed decisions; the seller's urgent need to sell can provide context for negotiations; and knowing the timeline for the sale is essential for both parties to align their expectations. These elements do not create an unfair advantage for one party over the other, as they play a role in the negotiation process while maintaining the integrity of agency duties.
