Final answer:
A radio ad for the brokerage would not be placed into a client file, as it is a marketing material for the brokerage and not specific to any one client's real estate transaction.
Step-by-step explanation:
The client file in real estate typically includes all relevant documents and information about real estate transactions that involve a particular client. This might include documents such as a property listing, a rental agreement, and an earnest money receipt. These are all directly related to the real estate transaction and the client's interests in that transaction.
On the other hand, a radio ad for the brokerage is a marketing material used to promote the services of the brokerage itself and is typically not related to a single client or transaction. Therefore, the radio ad would not be placed into a client file as it does not pertain to the specifics of the individual client's transaction or property.
