Opendoor has also sought to expand its efforts to make viewing those homes just as seamless. The company enables potential customers to check out a home by opening it with the app seven days a week. Wu said that most potential buyers go to the house each of the seven days up to the transaction, and then seven days after the transaction happens. Given that it’s such a significant step for any home owner, it makes sense that a lot of planning and consideration would go into the process. The next step is to create a sort of trade-up system, where Opendoor works to create a streamlined way to turn around an existing home for a new home.
