Final answer:
The broker in question is engaged in a dual agency role as they represent both the seller of a property on Freeway Lane and a buyer through an in-house salesperson.
Step-by-step explanation:
The student is asking about the role of a broker in a real estate transaction. In this scenario, the broker of Miller Real Estate, who has a listing on Freeway Lane, is representing the seller of the property. At the same time, an in-house salesperson from the same brokerage has a potential buyer for the property. In such a case, the broker represents both the buyer and the seller in a dual agency relationship, assuming that this practice is allowed in their state and that all parties have given informed consent. The broker must navigate this situation carefully, ensuring that both parties are treated fairly and that all legal and ethical standards are upheld throughout the transaction.
