How to Calculate Cap Rate for a U.S. Rental Property
Targeted question: How do you calculate Cap Rate for a rental property?
Short answer: Cap Rate = Net Operating Income (NOI) ÷ Property Purchase Price. Example: a $400,000 rental that generates $42,000 in annual rent and has $10,000 in annual operating expenses has NOI of $32,000 and a Cap Rate of 8%.
How do you calculate Cap Rate for a rental property?
Cap Rate = Net Operating Income (NOI) ÷ Property Purchase Price.
Worked example: a $400,000 single-family rental in Tampa, FL generates $3,500/mo in rent ($42,000/yr). Property taxes, insurance, HOA, management and maintenance total $10,000/yr. NOI is $32,000. Cap Rate = $32,000 / $400,000 = 8.0%.
What goes into Net Operating Income?
NOI = Gross Annual Rent − Operating Expenses. Operating expenses include:
- Property taxes
- Insurance
- HOA / association fees
- Property management (typically 8–10% of gross rent)
- Repairs and maintenance (budget 5–10% of gross rent)
- Vacancy allowance (budget 5–8% of gross rent)
- Utilities (if paid by landlord)
NOI excludes mortgage principal and interest, depreciation, and capital improvements.
What is a good Cap Rate in 2026?
| Cap Rate band | Interpretation |
|---|---|
| < 4% | Low yield; typically appreciation-driven markets |
| 4–6% | Average Class A, low-risk markets |
| 6–8% | Solid income-focused single-family / small multi |
| 8–10% | Strong; usually secondary markets or value-add |
| > 10% | Needs extra due diligence on condition, tenants |
These bands are rules of thumb — always benchmark against the local sub-market.
Decision framework: should you buy based on Cap Rate alone?
No. Use Cap Rate as a first filter, then layer three additional checks:
- Cash-on-Cash Return — does leveraged return clear your hurdle (typical: 8%+)?
- IRR over 10 years — does long-horizon return justify the opportunity cost?
- Rent trend — is comparable rent rising, flat or falling over the last 6–12 months?
A property that passes all four checks is a qualified candidate.
