How One Landlord Uses the 50 Percent Rule for Accurate Cash Flow

In episode 64, Lucas and Luna dive into the 50 percent rule—a back-of-the-envelope heuristic that many landlords use to estimate operating expenses on rental properties. Lucas explains why the rule exists, where it came from (attributed to real estate investor and author Brandon Turner), and how it can prevent rookie cash flow mistakes. Using a concrete example of a $1,200/month rent duplex, Lucas shows how applying the rule would set aside $600/month for expenses, leaving $600 for the mortgage—and then reveals the pitfalls: it doesn't account for property-specific tax rates, insurance spikes, or deferred maintenance. Luna challenges the rule's universal applicability and shares a story of a landlord with a new build in Texas where expenses were only 35 percent. The hosts end with a practical framework: use the 50 percent rule during initial screening, then validate with a detailed pro forma and local comps before closing. Perfect for investors who want a fast, reliable cash flow filter without analysis paralysis. #50PercentRule #RentalPropertyCashFlow #RealEstateInvesting #LandlordStrategy #ExpenseRatio #CashFlowAnalysis #BrandonTurner #PropertyManagement #OperatingExpenses #DuplexExample #RealEstateMath #InvestorTips #Finance #Business #FexingoBusiness #BusinessPodcast #RealEstate #RentalIncome Keep every episode free: buymeacoffee.com/fexingo
