 Hart, a Canadian businessman, and a man known as Capitan Knox.The Barrows struck a deal with Hart and agreed to buy the lands from him at a rolling option, meaning that they would buy them in parts and purchase them at market price.Both of them benefited from the agreement since the Barrows did not have the capital to purchase upfront, while Hart sold the properties at an increasing market price since the values of the lands grew due to the neighborhood developments.
