Cap Rate and Cash-on-Cash Return Explained
Cap rate and cash-on-cash return are the two metrics professional real estate investors use most often to evaluate and compare properties. They measure different things — and knowing which to use when is what separates an educated buyer from one flying blind.
Capitalization Rate (Cap Rate)
The Formula
Cap Rate = Net Operating Income (NOI) ÷ Current Market Value
Where NOI = Gross Income − Operating Expenses
(NOI does NOT include mortgage payments)What Cap Rate Tells You
Cap rate answers: "If I bought this property all-cash today, what yield would I get on my money?" It strips out financing, making it a pure measure of property-level income efficiency. This makes it ideal for:
- Comparing properties within a market — a 7% cap rate property is a better income producer than a 5% cap rate property in the same neighborhood (assuming similar risk).
- Valuing income properties — if you know the market cap rate, you can back into a property's value: Value = NOI ÷ Cap Rate.
- Market-level benchmarking — cap rates compress (fall) as prices rise; expanding cap rates signal a buyer's market.
What Cap Rate Doesn't Tell You
- It doesn't reflect your actual returns if you used leverage (a mortgage). For that, use cash-on-cash.
- It doesn't account for appreciation — cap rate is a snapshot of current income, not total return.
- It can't be compared across wildly different markets. A 5% cap rate in Manhattan is a different risk proposition than a 5% cap rate in rural Iowa.
Cap Rate Benchmarks by Market Tier
| Market tier | Typical cap rate range | Examples |
|---|---|---|
| Gateway / Super Primary | 3–5% | NYC, LA, SF, Seattle, Boston |
| Primary / Mid-Tier | 5–7% | Denver, Austin, Phoenix, Nashville, Miami |
| Secondary | 6–9% | Columbus, Charlotte, Raleigh, Salt Lake City |
| Tertiary / Rural | 8–12%+ | Smaller markets, rural areas |
These are single-family residential benchmarks. Multifamily and commercial properties have their own cap rate norms.
Worked Example
Property A: Single-family home in Phoenix
Purchase price: $380,000
Monthly rent: $2,400 → Annual gross: $28,800
Operating expenses (taxes $3,800, insurance $1,200, management $2,304, maintenance $4,000, vacancy 5% = $1,440): $12,744
NOI: $28,800 − $12,744 = $16,056
Cap Rate: $16,056 ÷ $380,000 = 4.2%
This is on the low end for Phoenix; suggests the buyer is paying up for appreciation potential or quality.
Cash-on-Cash Return (CoC)
The Formula
Cash-on-Cash Return = Annual Pre-Tax Cash Flow ÷ Total Cash Invested
Annual Pre-Tax Cash Flow = NOI − Annual Mortgage Payments (P+I)
Total Cash Invested = Down payment + Closing costs +
Initial repairs + Furnishing (for STR)What CoC Tells You
CoC answers: "What annual return am I getting on the dollars I actually put in?" It accounts for leverage — the fact that you're financing part of the purchase. This makes it the most relevant metric for most individual investors who use mortgages.
Worked Example (continued from above)
Same Phoenix property with 25% down at 7% interest, 30-year fixed
Down payment: $95,000
Closing costs: $7,600 (2% of purchase)
Initial repairs/prep: $5,000
Total cash invested: $107,600
Loan amount: $285,000 → Monthly P&I at 7%: ~$1,897 → Annual: $22,764
NOI: $16,056
Pre-tax cash flow: $16,056 − $22,764 = −$6,708/year (negative)
Cash-on-Cash Return: −$6,708 ÷ $107,600 = −6.2%
At 7% mortgage rates, this Phoenix property produces negative cash flow — the buyer is betting on appreciation.
The Relationship Between Cap Rate and Interest Rates
A property cash-flows positively when its cap rate exceeds its mortgage rate. At 7% interest rates, you generally need a cap rate above 6–7% to break even on cash flow with a standard 25% down payment. This is why many markets that cash-flowed at 3–4% interest rates no longer do at 6–7%.
Targets by Strategy
| Strategy | Target CoC | Note |
|---|---|---|
| Long-term rental (LTR) | 6–10% | Harder to achieve in high-cost markets at current rates |
| Short-term rental (STR) | 10–20% | Higher risk/work; regulatory risk adds to underwriting |
| Value-add renovation | 8–15% (post-stabilization) | Initial CoC is often negative during renovation |
| Appreciation play | Negative to 4% | Investor betting on price growth; cash flow is secondary |
Quick Reference
- Use cap rate to compare properties, value income assets, and measure market conditions.
- Use cash-on-cash to evaluate your actual annual return given your specific financing.
- Both metrics use NOI — which excludes mortgage payments, depreciation, and income taxes.
- Neither metric captures appreciation. Total return = cash flow yield + appreciation + principal paydown.
