Which activity is NOT typically associated with a salesperson working with a buyer?

The correct answer is related to the specific role of a salesperson in the context of working with a buyer. Designing and implementing a marketing plan is primarily associated with the responsibilities of a listing agent or seller’s representative, whose role is to promote the property for sale and attract potential buyers. In contrast, a salesperson working with a buyer focuses more on understanding the buyer's needs, showing properties, preparing necessary documentation, and recommending professionals to assist in the buying process.

Determining the buyer’s needs and wants is crucial as it helps the salesperson understand what kind of properties to search for on behalf of the client. Similarly, preparing an agreement of purchase and sale is a fundamental task that ensures the buyer’s interests are effectively represented in the transaction. Showing properties that align with the buyer's criteria is also a key function, as it allows the salesperson to present options that might meet the buyer's expectations. Recommending third-party professionals, such as home inspectors or mortgage brokers, is essential to help the buyer navigate the purchasing process efficiently.

In summary, the reason for identifying the activity of designing and implementing a marketing plan as not typically associated with a buyer's representative is anchored in the distinction of roles within real estate transactions.
