Cap Rate
How capitalization rate relates net operating income to price, and why the same cap rate can mean very different things.
AuthorKitsey Behrman
01
What It Means
Cap rate is net operating income divided by purchase price. Net operating income is income after operating expenses but before financing, so cap rate describes the property, not your loan.
Example: A property with a Net Operating Income (NOI) of $60,000 and a value of $1,000,000 has a 6.0% cap rate.
Generally, lower cap rates are associated with properties in stronger or more stable markets, properties with lower perceived risk, or properties where investors are willing to accept lower returns in exchange for greater stability.
Higher cap rates often reflect greater perceived risk, increased management intensity, location challenges, market conditions, or opportunities where investors expect a higher return to compensate for additional uncertainty.
Cap rates also vary by property type, location, tenant quality, lease structure, and overall market conditions. A higher or lower cap rate is not inherently “better”—it simply reflects different risk and return characteristics. Always compare cap rates among similar property types within the same market. Cap rate is one tool for evaluating an investment and should be considered alongside cash flow, financing, property condition, market trends, and your overall investment goals.
Did You Know?
Two properties can have the exact same cap rate but perform very differently as investments. Financing, future appreciation, deferred maintenance, lease quality, vacancy rates, operating expenses, and market conditions can all significantly affect long-term performance. Cap rate is an excellent screening tool—but it should never be the only factor in an investment decision.

Why It Matters
Cap rate is the common language of commercial valuation. It lets you compare two very different buildings on the same terms, and it's how buyers and appraisers translate income into value.
It also cuts both ways at sale: improving net operating income raises value at a given cap rate, and rising market cap rates lower value even when your income holds steady.

Questions to Ask
- Is this cap rate calculated on actual or projected income?
- Which expenses were included, and were reserves and management left out?
- What cap rates have comparable properties actually traded at recently?
- Is income supported by signed leases with creditworthy tenants?
- What would the value be if cap rates moved one point against me?
04
Common Mistakes
- Comparing a pro forma cap rate to a trailing actual cap rate.
- Assuming a high cap rate means a better deal rather than more risk.
- Leaving management out of expenses to make the number look stronger.
- Applying a metro-area cap rate to a small rural market.

What this result means
Cap rate measures a property's unleveraged return — what the property earns relative to its value, before any financing. It is calculated as net operating income divided by property value. Because it ignores your loan, two buyers paying the same price for the same building share the same cap rate even if one pays cash and the other borrows 75 percent.
Net operating income deliberately excludes mortgage payments, depreciation, income taxes, and capital expenditures. That is what makes cap rate useful for comparing properties to one another and to the broader market — and also what makes it incomplete on its own.
A higher cap rate generally signals higher expected return and higher perceived risk; a lower cap rate often reflects a stronger location, stronger tenancy, or stronger demand. Cap rate says nothing about your monthly cash flow after debt service — for that, look at the Cash-on-Cash Return Calculator.
The operating expense ratio shown above compares expenses to effective gross income. If it looks unusually low, confirm that taxes, insurance, management, and realistic maintenance reserves are all included.
