In the world of real estate, the word "caravan" is used to describe a method of selling a home in which a group of real estate agents are invited to tour a handful of different homes that are on the market. The purpose of this is to allow other agents to see the homes and suggest them to their own clients, who may not have even known about the houses. This can be incredibly helpful in places where the market is slow because more real estate agents mean more potential buyers, and the more the real estate agent sees and learns about the house, the more information they are able to offer to people who may be interested. A caravan is similar to an open house, except it usually features a series of homes versus a single property and is for real estate agents only.
