Which of the following is a requirement for an exclusive right to sell listing?

An exclusive right to sell listing is a type of agreement between a property owner and a real estate broker that gives the broker the exclusive right to represent the seller in the sale of the property. This means that no matter who sells the property—whether it's the broker, the owner, or another agent—the broker is entitled to a commission.

The requirement that only one broker is authorized to sell is crucial because it prevents any potential conflicts that might arise from multiple brokers trying to sell the same property simultaneously. This exclusivity encourages the broker to invest more effort and resources into marketing the property, knowing they will receive compensation if the property sells. This structure is beneficial for both the seller, who gets focused representation, and the broker, who can confidently invest time and marketing funds.

In contrast, having authority given to multiple brokers would create competition among them, making the selling process less efficient and clear. Payment of commission only if the broker sells does not reflect the nature of an exclusive right to sell, as the broker gets paid regardless of who sells the property. Lastly, the idea that the agent works for free contradicts the fundamental principles of a commission-based real estate transaction, where the broker's efforts are compensated regardless of whether they make the sale themselves.
