Which of the following would NOT be considered a type of single agent?

A landlord's agent represents the interests of a property owner in rental agreements or property management. This role is a clear example of a single agency relationship, as the agent solely advocates for the landlord's interests without any conflicting obligations.

A buyer's agent is specifically tasked with representing the buyer in a real estate transaction. This role exemplifies a single agency relationship, where the agent's duties are entirely focused on the buyer's needs and interests, ensuring that their best interests are prioritized throughout the buying process.

A seller's agent serves to represent the seller in a real estate transaction, advocating for their interests exclusively. Like a buyer's agent, this role exemplifies single agency, where the agent is dedicated to fulfilling the seller's objectives in the sale of their property.
