Under which listing agreement does the seller lose their right to compete for commission?

The exclusive right to sell listing is significant because it grants the listing agent the sole authority to represent the seller in the sale of the property. Under this type of agreement, the seller cannot sell the property themselves without having to pay the agent's commission, regardless of who ultimately sells the property. This arrangement provides the agent with an incentive to market the property effectively since they are guaranteed a commission if the property is sold during the term of the listing.

This contrasts with other listing agreements—such as open listings, where multiple agents may work to sell the property and only the agent who brings in the buyer earns a commission, and exclusive agency listings, where the seller retains the right to sell the property independently without owing a commission to the agent if they find a buyer on their own. The net listing agreement also allows the seller a level of competition regarding the sale proceeds, as it involves setting a minimum price that the seller wants to receive, with the agent keeping the amount over that price as commission.

Therefore, the exclusive right to sell listing distinctly removes the seller's competitive ability regarding commission, making it the correct choice.
