An open listing is a type of listing agreement in which the seller or landlord authorizes multiple real estate agents to market their property. The seller or landlord is not obligated to pay a commission to any agent and may sell or rent the property themselves. This type of listing is different from an Exclusive Listing agreement in which the seller or landlord authorizes only one agent to market the property and agrees to pay a commission to that agent only if the property is sold or rented through that agent.
