Final answer:
A multiple listing authorization gives a real estate broker the authority to list a property on a multiple listing service, increasing its visibility to potential buyers and cooperating with other brokers.
Step-by-step explanation:
A multiple listing authorization, commonly referred to as a Multiple Listing Service (MLS) agreement, grants a real estate broker the authority to list a property for sale on a multiple listing service, which disseminates the information to a large network of cooperating brokers. When a property is listed on the MLS, it maximizes the exposure of the property to potential buyers, as it allows other brokers and their clients to easily access the details of the listing. This type of authorization enables the listing broker to work with other brokers on behalf of the seller, thereby increasing the chances of a sale. It's also important to note that the exact nature of the authority given to the broker can vary depending on the specific terms and conditions set out in the multiple listing authorization agreement.
