Which of the following is NOT considered a customer in a real estate transaction?

In a real estate transaction, a customer is typically defined as someone who is not represented by a licensed agent but is still engaged in a transaction. This individual benefits from the services provided by the agent and can receive information and assistance without a fiduciary relationship being established.

When a buyer engages an agent for assistance, they enter into a formal agency relationship, which means the agent owes them fiduciary duties such as loyalty, confidentiality, and full disclosure. This relationship distinguishes the buyer as a client rather than a customer. Clients are entitled to a higher level of service and representation compared to customers.

On the other hand, a potential buyer attending an open house, an owner represented by a buyer's agent, and a potential tenant managed by an agent are all classified as customers in this context. They are seeking information and assistance in the transaction but do not have the same level of representation that clients have. Therefore, engaging an agent for assistance denotes a client relationship, making it the correct choice that is not considered a customer in a real estate transaction.
