Snap & Map: Free Property ROI Calculator and Forecast
Snap & Map is a no-signup property ROI calculator for buyers, owners, and small real estate investors. Enter an address and your own purchase, financing, rent, expense, inflation, and appreciation assumptions to compare possible outcomes across an editable multi-year forecast.
What the Property Forecast Calculates
- Future property value using your editable annual appreciation assumption
- Projected equity after mortgage amortization and estimated selling costs
- Cap rate from annual rent and operating expenses before financing
- Cash-on-cash return based on first-year cash flow and invested cash
- Low, base, and high scenarios to show how compounding changes the range
Why Assumptions Matter
A rent estimate alone is not investment yield. Property taxes, insurance, maintenance, financing, vacancy, and cash paid at closing can materially change the result. A small change in annual appreciation also compounds over time, which is why Snap & Map shows a scenario range rather than a guaranteed prediction.
