A listing agreement is an employment contract between the seller and the broker. It should always be in writing so each party understands the relationship. Though there are a few types of listing agreements, an Exclusive Right to Sell agreement appoints one broker as the seller’s representative. This arrangement is advantageous to the seller because then one broker is responsible for all marketing, communication, and negotiation on the seller’s behalf, creating more accountability. A broker will also typically spend more time and effort on this type of listing since the seller has given a financial commitment to the broker.
