What must be included in the appointment of agents for an intermediary transaction?

When an intermediary transaction is involved, it is essential to include the identity of each appointed agent. This requirement stems from the nature of intermediary transactions, where a broker represents both the buyer and the seller in the same transaction. It is crucial that all parties involved are aware of who the appointed agents are to ensure transparency and maintain trust throughout the process. Keeping the identities of the agents known helps to avoid any conflicts of interest and ensures that both the buyer and seller have clear lines of communication and representation.

In contrast, while the property's location, commission structure, and estimated closing costs are important considerations in real estate transactions, they are not specifically mandated elements in the appointment of agents in an intermediary situation. The focus on identifying the agents appointed to represent the parties is central to managing the dual representation effectively, making it the correct choice for this question.
