What must Madeline do to represent both the buyer and seller in a transaction at her single-agency firm?

In order for Madeline to effectively represent both the buyer and the seller in a real estate transaction within the context of a single-agency firm, the requirement is that she should obtain informed consent from both parties to ensure that they are fully aware of the implications of her dual representation. This concept hinges on the principles of disclosure and consent, which are paramount in establishing transparent and ethical communication between all involved parties.

The possibility of representing both a buyer and a seller, sometimes referred to as dual agency, can be permissible under certain conditions, especially if it is aligned with state laws and regulations governing real estate practices. However, without informed consent, Madeline would run the risk of appearing to favor one side over the other, leading to potential conflicts of interest and legal challenges.

While the notion of acting as a designated agent for one party is a common practice in certain brokerage arrangements, it would not be feasible in a strict single-agency context unless informed consent is secured. Thus, the correct action for Madeline is to obtain informed consent from both the buyer and the seller, ensuring a compliant and ethical approach to her role in the transaction.
