📊 Key Property Analysis Formulas

Here are the main formulas used in the calculator, written in plain text:

  1. Monthly Mortgage Payment =
    (Loan Amount × Interest Rate / 12) / (1 - (1 + Interest Rate / 12)^(-Loan Term × 12))
  2. Annual Gross Rental Income =
    Monthly Rent × 12
  3. Operating Expenses =
    Sum of monthly property expenses × 12
  4. Net Operating Income (NOI) =
    Gross Rental Income - Operating Expenses
  5. Cash Flow =
    NOI - Annual Debt Service (total mortgage payments in a year)
  6. Cap Rate =
    (NOI / Purchase Price) × 100
  7. ROI (Return on Investment) =
    (Annual Cash Flow / Total Cash Invested) × 100
  8. Total Cash Invested =
    Down Payment + Closing Costs + Initial Repairs

🧾 Example Calculation

Let’s say you want to analyze a property with these details:

  • Purchase Price: $250,000
  • Down Payment: $50,000
  • Monthly Rent: $2,000
  • Monthly Expenses (insurance, taxes, maintenance): $500
  • Loan Amount: $200,000
  • Interest Rate: 5% annually
  • Loan Term: 30 years

Step-by-Step Analysis:

  1. Monthly Mortgage Payment ≈ $1,073.64
  2. Gross Rental Income = $2,000 × 12 = $24,000
  3. Operating Expenses = $500 × 12 = $6,000
  4. NOI = $24,000 – $6,000 = $18,000
  5. Annual Mortgage Payments = $1,073.64 × 12 = $12,883.68
  6. Cash Flow = $18,000 – $12,883.68 = $5,116.32
  7. Cap Rate = ($18,000 / $250,000) × 100 = 7.2%
  8. ROI = ($5,116.32 / $50,000) × 100 ≈ 10.23%

This example shows a decent ROI and positive cash flow—indicating a potentially profitable investment.

🏡 Why Use a Property Analysis Calculator?

Here are a few strong reasons:

  • Avoid Bad Investments: Filter out underperforming properties.
  • Estimate Cash Flow: Know how much you’ll earn monthly.
  • Calculate ROI: Assess profitability before buying.
  • Plan Finances: Understand how loan structure affects your returns.
  • Compare Properties: Use data, not guesses, for comparisons.

🔍 Additional Investment Metrics You Can Assess

  • Debt Coverage Ratio (DCR)
    = Net Operating Income / Debt Service
    A value above 1 indicates the property generates enough income to cover the debt.
  • Break-Even Ratio
    = (Operating Expenses + Debt Service) / Gross Income
    A lower value means better financial health.

❗Tips for Accurate Analysis

  • Be realistic with rent income and occupancy rates.
  • Include a vacancy rate (5–10%) to reflect market conditions.
  • Factor in unexpected repairs and maintenance.
  • Account for local property taxes and insurance variations.
  • Revisit your analysis periodically as costs and income change.
