ROI Calculation for Investment Properties
Analyze investment property ROI across scenarios and financing options
What You Can Do
Get instant ROI calculations for residential and commercial properties by inputting acquisition cost, rental income, expenses, and financing terms. Claude compares multiple scenarios (different down payments, loan terms, holding periods) side-by-side so you can identify which investment structure delivers the highest returns. You'll see detailed breakdowns of cash flow, cap rate, cash-on-cash return, and internal rate of return to make confident acquisition decisions.
Features
Analyze the same property under different financing terms, down payments, and holding periods simultaneously to identify optimal investment structures
Calculate cash-on-cash return, cap rate, internal rate of return (IRR), net present value (NPV), and total profit across your holding period
Model monthly and annual cash flow by deducting operating expenses, debt service, property taxes, insurance, and maintenance from rental income
Compare fixed-rate mortgages with different amortization periods, interest-only periods, balloon payments, and adjustable-rate loans
Instantly see how ROI changes if rental income drops, expenses rise, or property appreciation slows to stress-test your investment thesis
Compare ROI metrics across multiple properties to prioritize which acquisitions will deliver the best risk-adjusted returns
Include depreciation benefits, 1031 exchange scenarios, and capital gains projections to understand your true after-tax returns
Example Output
Example 1: Single Property Multi-Scenario Analysis
Property: 4-plex, $500k acquisition price, $48k annual rental income
| Scenario | Down Payment | Loan Term | Monthly P&I | Year 1 Cash Flow | Cash-on-Cash | 10-Yr IRR |

| Aggressive | 15% | 25-yr | $2,653 | ($4,296) | -3.4% | 5.8% |
Example 2: Sensitivity Analysis
"What if rental income drops 10% or vacancies increase to 8%?"
- Base case 10-year IRR: 8.2%
- With 10% income reduction: 6.4%
- With 8% vacancy rate: 5.9%
Example 3: Portfolio Prioritization
Analyzing 5 potential acquisitions:
- Property A: 9.2% IRR, $12k annual cash flow, best for growth
- Property B: 6.8% IRR, $28k annual cash flow, best for cash flow
- Property C: 10.1% IRR, $8k annual cash flow, best for total returns
