Under which of the listing agreements below is a listing agent promised a commission if the property is sold (by anyone)?

An open listing agreement allows the property owner to sell the property themselves or engage multiple agents. In this case, only the agent who brings a buyer is entitled to a commission. Therefore, if the owner sells the property independently, the listing agent does not earn a commission.

In a net listing agreement, the seller specifies the minimum amount they wish to receive from the sale, and any amount above this threshold goes to the agent as commission. This type of agreement does not ensure a commission for the agent if the seller sells the property without their involvement, thus making it dependent on the agent's success.

An exclusive agency listing agreement provides the agent with exclusive rights to sell the property, but the owner retains the right to sell it themselves without paying a commission to the agent. Therefore, if the property is sold by the owner, the agent does not receive any commission, unlike in the exclusive authorization and right-to-sell agreement.
