Hannah Ingram, a 22-year-old entrepreneur, bought an automated car wash in Tennessee for $140,000 and turned it into a highly profitable venture, earning around $5,500 per month with minimal effort. Ingram leveraged seller financing to minimize her initial investment and made strategic improvements, including upgrading equipment and marketing, to boost profitability. Her car wash now operates almost entirely on autopilot, allowing her to enjoy a substantial income with minimal hands-on work.
