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

Multi-Scenario Comparison

Analyze the same property under different financing terms, down payments, and holding periods simultaneously to identify optimal investment structures

Comprehensive ROI Metrics

Calculate cash-on-cash return, cap rate, internal rate of return (IRR), net present value (NPV), and total profit across your holding period

Cash Flow Analysis

Model monthly and annual cash flow by deducting operating expenses, debt service, property taxes, insurance, and maintenance from rental income

Financing Structure Modeling

Compare fixed-rate mortgages with different amortization periods, interest-only periods, balloon payments, and adjustable-rate loans

Sensitivity Analysis

Instantly see how ROI changes if rental income drops, expenses rise, or property appreciation slows to stress-test your investment thesis

Portfolio Comparison

Compare ROI metrics across multiple properties to prioritize which acquisitions will deliver the best risk-adjusted returns

Tax Implication Estimates

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

ScenarioDown PaymentLoan TermMonthly P&IYear 1 Cash FlowCash-on-Cash10-Yr IRR
Conservative25%30-yr$1,908$8,5446.8%8.2%
Moderate20%30-yr$2,290$3,1202.5%6.1%
Aggressive15%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

What's Included

  • ROI Calculation Engine: Complete formulas for cap rate, cash-on-cash return, IRR, NPV, and cash-on-cash payback period with step-by-step breakdowns
  • Financing Comparison Templates: Pre-built prompts for conventional loans, FHA loans, investment portfolio loans, and portfolio-based lending scenarios
  • Expense Categorization Framework: Standard operating expense categories (taxes, insurance, maintenance, utilities, management fees, HOA dues) with industry benchmarks
  • Multi-Property Portfolio Tool: Framework for comparing ROI metrics across 5-10 properties simultaneously to rank acquisitions by total return, cash flow, or risk-adjusted returns
  • Scenario Documentation Templates: Records for tracking assumptions (appreciation rate, expense growth, rent inflation, holding period) so you can audit what changed between analyses

Who It's For

  • Real Estate Investment Managers
  • Commercial Property Investors and Brokers
  • Residential Landlords and Fix-and-Flip Operators
  • Private Equity Real Estate Partners

Best For

  • Pre-acquisition due diligence and property evaluation
  • Comparing financing options before committing to a loan
  • Building 5 to 10 year financial projections for portfolio decisions
  • Stress-testing assumptions if market conditions deteriorate
