Real estate investment analysis goes beyond the mortgage payment. This calculator evaluates a property's financial performance using key metrics: cap rate, cash-on-cash return, gross rent multiplier, net operating income, and total return. Whether you are analyzing a rental property or deciding between buying and renting, these metrics tell you if the numbers make sense.
Key Real Estate Investment Metrics
Real estate investors use several metrics to evaluate properties. No single number tells the full story. Cap rate is most useful for comparing properties in similar markets. Cash-on-cash return is most useful for leveraged investments where you are using a mortgage.
| Metric | Formula | What It Shows |
|---|---|---|
| Cap Rate | NOI / Property Value | Unlevered yield on property value |
| Cash-on-Cash | Annual Cash Flow / Cash Invested | Return on actual cash invested |
| GRM | Price / Gross Annual Rent | Quick relative value comparison |
| NOI | Gross Rent - Vacancy - Operating Expenses | Income before debt service |
| DSCR | NOI / Annual Debt Service | Ability to cover mortgage from income |
Cap Rate Benchmarks
Cap rates vary by market and property type. Low cap rates indicate high property values relative to income (common in expensive markets like San Francisco or New York). Higher cap rates generally signal higher expected returns but also higher risk or weaker market fundamentals.
Cap Rate = Net Operating Income / Purchase Price × 100% Example: $12,000 NOI on a $200,000 property = 6% cap rate
Typical cap rate ranges: 4-5% (high-cost urban), 6-8% (mid-tier markets), 8-12%+ (secondary/rural markets).
Frequently Asked Questions
What is a good cap rate for rental property?⌄
A "good" cap rate depends on the market, property type, and your investment goals. In expensive coastal markets, 4-5% is common. In Midwest or Sun Belt secondary markets, 6-8% is typical. Cap rate alone does not determine if a property is a good investment -- location quality, appreciation potential, and management ease also matter significantly.
What is the 1% rule in real estate?⌄
The 1% rule is a rough screening tool: if the monthly rent is at least 1% of the purchase price, the property might cash flow positively. A $200,000 property should rent for at least $2,000/month to pass the 1% test. In high-cost markets, achieving the 1% rule is nearly impossible. It is a starting screen, not a definitive analysis.
What expenses should I include in real estate analysis?⌄
Common operating expenses: property taxes, insurance, property management (8-12% of gross rent), maintenance/repairs (5-10% of gross rent), vacancy allowance (5-10%), HOA fees, utilities (if landlord-paid), and capital expenditure reserves for roof, HVAC, appliances (5-15%). New investors often underestimate expenses, especially maintenance and capex.
What is DSCR and why do lenders use it?⌄
Debt Service Coverage Ratio = NOI / Annual Debt Payment. Lenders use DSCR to assess whether a property's income can support the loan payments. Most lenders require DSCR of 1.20-1.25 or higher, meaning the property generates 20-25% more income than needed to cover the mortgage, providing a cushion for vacancies and unexpected costs.
