Open houses are largely a holdover from an earlier era of real estate marketing — back when buyers relied on printed MLS books, newspaper ads, yard signs, and physically driving around to see what was available. Decades ago, walking through a home in person was often the only practical way to understand the property. Today, buyers can preview homes online through professional photography, video walkthroughs, 3D tours, 360-degree media, floor plans, Google Maps, neighborhood data, and listing portals before ever stepping inside. Because of that, open houses are often less productive as a selling tool and more useful as a lead-generation opportunity for the listing agent or the agent hosting the open house. For sellers who value privacy, security, and serious buyer activity, private showings with qualified buyers and licensed agents are often a more controlled and efficient approach.
