Which of the following activities may a transaction broker NOT conduct for any party's benefit?

A transaction broker serves as a neutral intermediary in a real estate transaction, which means they do not represent the interests of either party. Their role is to facilitate the transaction rather than advocate for one side or the other. As such, the activities listed—inspection, investigation, and analysis—are considered functions that typically require a fiduciary duty or a level of advocacy that a transaction broker does not engage in.

By not conducting inspections, investigations, or analyses for the benefit of either party, a transaction broker maintains their neutral position. This neutrality is crucial in a transaction environment to ensure that both parties are treated fairly and that the transaction proceeds without bias or conflict of interest. This is why all of those activities are correct answers to the question; they fall outside the scope of a transaction broker's permissible actions, as such activities would suggest an allegiance to one party over the other.
