Which of the following is NOT a part of the obligation when a property management agreement is established?

The correct choice highlights that maintaining a client file is not an explicit obligation defined within the framework of a property management agreement. In property management, the primary obligations often include actively engaging in finding tenants, ensuring there is mutual understanding and agreement between both parties, and having the agreement duly signed to validate the arrangement.

In contrast, while maintaining thorough documentation and client files is a good practice and may be encouraged for operational efficiency and compliance reasons, it is not universally mandated as a part of the essential requirements for establishing the agreement itself. Client file management can vary based on different regulations, company policies, or individual practices, thus distinguishing it from the other elements that are more fundamentally tied to the initiation of a property management relationship.
