Which of the following describes when an agency relationship ends?

An agency relationship in real estate can indeed end for several reasons, and all the options listed contribute to this conclusion.

When a deal is completed, meaning the sale or lease has successfully gone through, the agency relationship typically concludes. This is because the primary purpose of the agent's role—to facilitate the transaction—has been fulfilled and there is no longer a need for that relationship.

Destruction of property can also result in the end of an agency relationship. If the property that the agent is handling is destroyed—whether through natural disaster or other unforeseen circumstances—the agent may no longer have a property to sell or lease, thereby terminating the agency relationship.

Additionally, if both parties agree to terminate the relationship, it is a valid reason for its conclusion. Agency relationships are based on mutual agreement, and if either the agent or the client decides they no longer require the services of one another, they can mutually agree to end the relationship.

Since each of these scenarios represents a valid cause for ending an agency relationship, the comprehensive nature of this answer is why it is correct to say that all of the listed choices contribute to the termination of the agency relationship.
