A builder only has a few properties available in a development. He feels that it is no longer necessary to have his onsite sales agent market these properties and decides to list the properties with a local brokerage firm. He wants to reward a particular firm for their past sales of his homes but wants to allow all of the local firms to market these properties. The type of listing that will accomplish this is

An open listing

Explanation:

In real estate an open listing is one in which the owner of a property contracts more than one agent to sell the property. The agent with the winning bid will eventually sell the property.

The opposite of this is the exclusive listing where the property owner only engages one agent to sell the property.

In the given scenario the builder feels that it is no longer necessary to have his onsite sales agent market these properties and decides to list the properties with a local brokerage firm. Thereby allowing all of the local firms to market these properties.

This is an open listing
