How To Use
Know if a rental property makes money before you buy
🚀 Getting Started
1
Enter Property Details
Purchase price, down payment, mortgage rate, and monthly rent from the listing or your research.
2
Add All Expenses
Property tax, insurance, maintenance reserve, management fees. Be realistic — underestimating kills returns.
3
See Cash Flow & ROI
Monthly cash flow, cap rate, and cash-on-cash return. Positive cash flow = money in your pocket every month.
4
Run Scenarios
What if vacancy hits 10%? What if rent drops? Stress-test the deal before committing capital.
📊 Terms Made Simple
Cash Flow: Rent collected minus ALL expenses (mortgage, taxes, insurance, maintenance, vacancy, management). Positive = money in your pocket. Negative = you're paying to own this property.
Cap Rate: Net Operating Income ÷ Property Value. Ignores financing — tells you how productive the property is as an asset. 5-10% is typical. Higher = better return, often higher risk.
Cash-on-Cash Return: Annual cash flow ÷ total cash you invested (down payment + closing costs). This is YOUR return on YOUR money. 8-12% is strong for rentals.
NOI (Net Operating Income): Annual rental income minus operating expenses — but NOT including mortgage payments. Lenders and investors use NOI to evaluate property value independently of financing.
