I'm a real estate investor and licensed agent, and I built this tool to reflect how I personally underwrite single-family investment properties. Most calculators use flat assumptions. This analysis adjusts maintenance, CapEx, and taxes based on the property — because that's what actually matters when evaluating a deal.

Want a second opinion on a deal? I'm happy to take a look.
