Real Estate ROI Calculator
Automate property investment ROI analysis with scenario modeling and detailed assumptions
What You Can Do
You can generate comprehensive return-on-investment analyses for any real estate investment in minutes. Claude calculates key metrics like cap rate, cash-on-cash return, and net present value while automatically modeling multiple scenarios (best case, base case, worst case) to stress-test your assumptions. Every calculation includes full documentation of your inputs, so you can audit your thinking, share analysis with partners, and iterate on different investment strategies.
Features
Generate all critical metrics (cap rate, cash-on-cash return, IRR, NPV) instantly from property details and financial assumptions
Compare best-case, base-case, and worst-case scenarios side-by-side to understand risk exposure across different market conditions
Automatically track and organize all inputs (purchase price, financing terms, rent growth, expense inflation) for full transparency and auditability
Generate month-by-month or year-by-year cash flow forecasts showing rental income, expenses, debt service, and net cash flow
See how ROI changes when individual assumptions shift (e.g., rental rates drop 5%, vacancy rises 2%), identifying your most critical assumptions
Calculate depreciation schedules, taxable income, and after-tax cash flow to understand true profitability
Evaluate multiple properties side-by-side using consistent methodology to identify the best risk-adjusted opportunity
Generate structured reports in markdown or CSV that you can share with lenders, partners, and financial advisors
