Mark Podolsky explains how raw land investing can create passive income without traditional real estate headaches. His model starts with tax-delinquent owners, comparable sales from the last 12 to 18 months, and offers around one-fourth of value for a 300% margin of safety. After due diligence on title, taxes, liens, maps, and ownership, he markets first to neighbors, then lists on buyer lists, Craigslist, Facebook, and land sites. He often recovers his money through a down payment, then collects monthly payments like $449 at 9% interest over 84 months. The business depends on mailing, marketing, urgency, scarcity, clear calls to action, and strong pricing anchors. He also uses virtual teams, templates, software, and GeekPay to automate operations. The key takeaway is to build recurring notes until passive income exceeds fixed expenses.
