Home Depot did sell prefab houses and tiny homes, some of which were priced under $50,000. These offerings might have included various brands and models with different features and sizes. To find the most current and accurate information on Home Depot's inventory of prefab houses and tiny homes within your budget, I recommend visiting the official Home Depot website or contacting your local Home Depot store directly. They will be able to provide you with the most up-to-date information on available products and prices.
