How Pro calculates
- Year-1 numbers use the same formulas as the free calculator and the Rental Deal Analyzer spreadsheet: NOI = effective gross income − operating expenses; repairs and CapEx are a % of scheduled rent; management is a % of collected income.
- Projection: rent and rent-based costs grow with rent growth, fixed costs with expense growth, value with appreciation. The loan is fixed-rate and fully amortizing.
- IRR uses the cash invested at year 0, each year's cash flow, and the net sale proceeds (value − selling costs − loan balance) in the sale year. Taxes, depreciation and refinancing are not modeled.
- Tested: every number matched the LibreOffice-recalculated spreadsheet for the 3 sample deals and 6 randomized deals (including 0% interest, all-cash and 1- and 10-year holds).
