Cap rate is one of the most quoted metrics in real estate investing — and one of the most misused. Understanding what a "good" cap rate looks like, and how to interpret it correctly, is essential before you underwrite your first deal.
What Is a Cap Rate?
Cap rate (capitalization rate) measures a property's potential return on an all-cash basis, ignoring financing.
The formula:
Cap Rate = Net Operating Income (NOI) ÷ Property Value
Where NOI = annual rental income minus all operating expenses (vacancy, taxes, insurance, management, maintenance, CapEx reserves) — but not including mortgage payments.
Quick Example
A property with $24,000 annual gross rent, $10,000 in operating expenses, and a purchase price of $200,000:
- NOI = $24,000 − $10,000 = $14,000
- Cap Rate = $14,000 ÷ $200,000 = 7.0%
What Is a "Good" Cap Rate?
The answer depends almost entirely on market, asset class, and your investment goals. There's no universal "good" cap rate — a 4% cap rate might be excellent in Manhattan but terrible in rural Ohio.
General Benchmarks by Market Type
| Market Type | Typical Cap Rate Range |
|---|---|
| Top gateway cities (NYC, LA, SF) | 2.5% – 4.5% |
| Major metros (Chicago, Dallas, Atlanta) | 4.5% – 6.5% |
| Secondary cities (Columbus, Indianapolis) | 6.0% – 8.5% |
| Tertiary/rural markets | 8.0% – 12%+ |
Higher cap rates generally come with lower appreciation expectations and higher operational risk. Lower cap rates indicate markets where investors accept lower current income in exchange for expected appreciation.
Cap Rates by Asset Class
| Asset Class | Typical Cap Rate Range |
|---|---|
| Class A single-family / multifamily | 3.5% – 5.5% |
| Class B multifamily | 5.0% – 7.0% |
| Class C value-add | 7.0% – 10%+ |
| Small commercial / mixed-use | 5.5% – 8.5% |
Cap Rate vs. Interest Rates: Spread Matters
One of the most important concepts serious investors track is the cap rate spread — the difference between a property's cap rate and the prevailing borrowing rate.
When you borrow at 7% on a deal with a 6% cap rate, you have negative leverage: financing is actually lowering your return. In this environment, cash-on-cash return will be lower than the cap rate.
When you borrow at 5% on a 7% cap rate deal, you have positive leverage: financing enhances your return, and cash-on-cash return will be higher than the cap rate.
In 2022–2024, rising interest rates compressed the spread in many markets — making deals that penciled at a 5% cap rate with 3.5% debt no longer work at the same price point.
How to Use Cap Rate Correctly
Use Cap Rate to Compare Properties
Cap rate is most useful when comparing similar properties in the same market. It strips out financing differences and gives you a level playing field on asset performance.
"Does this building produce better income per dollar of value than that one?"
Don't Use Cap Rate to Evaluate Your Actual Return
Because cap rate ignores financing, it doesn't tell you what your actual cash return will be. If you're buying with a mortgage (most investors are), your real return metric is cash-on-cash return — which accounts for your debt service.
Common Mistakes
1) Underestimating expenses to inflate cap rate A rosy NOI makes any cap rate look better. Always build in realistic vacancy (7–10%), property management (8–10% of rent), maintenance (5–10% of rent), and CapEx reserves (5–10% of rent). Skipping these is how investors end up surprised.
2) Using list-price cap rate Sellers often advertise cap rates based on optimistic rents or absent expenses. Always calculate cap rate yourself using your own expense assumptions and the actual purchase price you're negotiating.
3) Comparing cap rates across different markets A 4% cap rate in a high-appreciation metro and an 8% cap rate in a flat market can produce similar total returns over 10 years when you include appreciation. Don't chase cap rate without thinking about the full return picture.
Key Takeaways
- A "good" cap rate is contextual — market, asset class, and interest rate environment all matter.
- In most non-gateway markets, 6–8% is a reasonable benchmark for a single-family or small multifamily investment today.
- Cap rate spread (cap rate minus borrowing rate) determines whether leverage helps or hurts you.
- Cap rate is an asset-level metric; cash-on-cash return is your deal-level metric.
- Always build conservative expense assumptions — vacancy, management, maintenance, and CapEx reserves.
