What is Cap Rate in Real Estate Investment Analysis

---

The capitalization rate (cap rate) is one of the most important metrics in commercial real estate analysis. It’s also one of the most misunderstood and misused.

Understanding what is cap rate is in real estate requires knowing what it measures, what it doesn’t measure, and when to use it versus the dozen other metrics competing for attention.

Let’s strip away the mystique.

What Is Cap Rate in Real Estate?

Cap rate is the ratio of a property’s net operating income to its purchase price or current market value.

The formula is simple:

Cap Rate = Net Operating Income (NOI) / Property Value

A property generating $100,000 in NOI worth $1,250,000 has an 8% cap rate.

What Cap Rate Actually Measures

Cap rate measures unleveraged yield. It answers one question: If you bought this property with cash, what annual return would the operating income generate on your investment?

It ignores:

• Financing costs
• Future appreciation
• Tax benefits
• Exit strategies
• Capital improvements needed
• Lease rollover risks

Cap rate is a snapshot of current operating performance relative to price. Nothing more. Nothing less.

The Components: Understanding NOI

Net operating income is the numerator. Get NOI wrong, and cap rate becomes meaningless.

NOI = Gross Income – Operating Expenses

Gross Income includes:

• Rental income from leases
• Parking fees
• Storage income
• Other property-related revenue

Operating Expenses include:

• Property taxes
• Insurance
• Utilities (if owner-paid)
• Property management fees
• Repairs and maintenance
• Common area maintenance

NOI excludes:

• Debt service (mortgage payments)
• Capital expenditures
• Depreciation
• Income taxes
• Tenant improvements
• Leasing commissions

The exclusions matter. Cap rate measures operating performance, not total returns or cash flow to equity.

Calculate NOI wrong, and every subsequent analysis fails.

What Different Cap Rates Mean

Cap rates vary by property type, location, quality, and market conditions. Context is everything.

High Cap Rates (8-12%+):

• Higher risk properties
• Secondary or tertiary markets
• Older buildings requiring capital investment
• Single-tenant properties with rollover risk
• Markets with economic uncertainty

Mid-Range Cap Rates (6-8%):

• Stable properties in decent markets
• Multi-tenant with diversified income
• Average condition and location
• Moderate growth expectations

Low Cap Rates (4-6%):

• Premium properties in prime locations
• Major markets with strong demographics
• Newer buildings with credit tenants
• Low risk, stable income
• High growth expectations

A 4% cap rate isn’t “bad” and a 10% cap rate isn’t “good.” They reflect different risk-return profiles.

Cap Rate vs. Other Metrics

Cap rate is one tool in the analytical toolkit. Not the only tool.

Cash-on-Cash Return: Cash flow after debt service divided by cash invested. Accounts for leverage. Better measure of actual equity returns.

Internal Rate of Return (IRR): Time-weighted return including purchase, operations, and sale. Captures total investment performance over holding period.

Equity Multiple: Total cash returned divided by total cash invested. Simple measure of wealth creation.

Debt Service Coverage Ratio (DSCR): NOI divided by debt service. Measures ability to cover mortgage payments.

Cap rate is useful for comparing properties and understanding market pricing. It doesn’t tell you whether you’ll make money on a specific leveraged investment.

How Markets Use Cap Rates

Real estate markets have characteristic cap rate ranges by property type and geography.

Multifamily

• Class A urban core: 4-5%
• Class B suburban: 5-6.5%
• Class C tertiary markets: 7-9%

Office

• CBD Class A: 5-7%
• Suburban Class B: 7-9%
• Secondary markets: 8-10%

Retail

• Grocery-anchored: 6-7.5%
• Strip centers: 7-9%
• Single-tenant net lease: 5-7%

Industrial

• Logistics/distribution: 5-6.5%
• Warehouse: 6-8%
• Flex space: 7-9%

These are rough ranges. Actual cap rates vary significantly based on specific property characteristics and market timing.

Cap Rate Compression and Expansion

Cap rates move inversely to property values. When cap rates compress, values increase. When they expand, values decrease.

Cap Rate Compression (rates declining):

• Driven by increased demand for real estate
• Lower interest rate environments
• Strong economic fundamentals
• Competition among buyers
• Result: Property values increase

Cap Rate Expansion (rates rising):

• Reduced buyer demand
• Higher interest rate environments
• Economic uncertainty
• Increased risk perception
• Result: Property values decrease

Understanding cap rate movements helps predict value changes even without sales data.

The Relationship With Interest Rates

Cap rates don’t move in lockstep with interest rates, but there’s a relationship.

When interest rates rise, cap rates tend to rise as well. Higher borrowing costs reduce buyer demand, and required returns increase.

The spread between cap rates and interest rates matters. When 10-year Treasury yields approach or exceed cap rates, real estate becomes less attractive relative to risk-free alternatives.

Historically, cap rates typically exceed Treasury yields by 200-400 basis points. When spreads narrow, watch out.

Going-In Cap Rate vs. Stabilized Cap Rate

Timing matters in cap rate analysis.

Going-In Cap Rate: Based on NOI at the time of purchase. Reflects current occupancy and rent roll.

Stabilized Cap Rate: Based on projected NOI after lease-up, rent growth, or property improvements. Reflects expected future performance.

A property with 60% occupancy might have a 5% going-in cap rate but an 8% stabilized cap rate once fully leased.

Confuse these, and you’ll overpay based on future projections rather than current reality.

Using Cap Rates for Valuation

Cap rates provide a quick valuation methodology:

Property Value = NOI / Cap Rate

A property generating $200,000 NOI in a 7% cap rate market is worth roughly $2,857,000.

This is how appraisers and brokers estimate values. It’s also how investors quickly assess whether asking prices are reasonable.

But it’s just an estimate. Property-specific factors—deferred maintenance, tenant credit, lease terms, development potential—affect actual value beyond simple cap rate application.

The Terminal Cap Rate in DCF Analysis

In discounted cash flow analysis, the terminal cap rate determines exit value assumptions.

You project NOI for a holding period, then apply a terminal cap rate to the final year’s NOI to estimate the sale price.

Terminal cap rates are typically equal to or slightly above the going-in cap rates. The assumption: risk increases slightly over time as buildings age and leases roll.

Aggressive projections use low terminal cap rates (high exit values). Conservative projections use higher terminal cap rates (lower exit values).

Terminal cap rate assumptions dramatically affect IRR calculations. A 50-basis-point difference in the terminal cap rate can change the IRR by 200+ basis points.

Cap Rate Limitations and Misuses

Cap rate is useful. It’s not infallible.

What Cap Rate Doesn’t Account For:

Capital Expenditures: A property with $500,000 of deferred maintenance has the same cap rate as an identical property in perfect condition. The returns aren’t equivalent.

Lease Rollover: A building with leases expiring in one year has different risk than one with 10-year leases, even at identical cap rates.

Tenant Credit: Investment-grade tenants and mom-and-pop tenants produce different risk profiles not captured in cap rate.

Growth Potential: Properties in emerging markets may have higher cap rates but better appreciation potential than stabilized markets with low cap rates.

Financing Impact: Cap rate ignores leverage. Two properties with identical cap rates produce different equity returns based on financing terms.

Use the cap rate as one data point. Not the only data point.

Market Cycle Considerations

Cap rates change throughout real estate cycles.

Early Expansion: Cap rates high, values low. Best buying opportunities for risk-tolerant investors.

Late Expansion: Cap rates compressed, values high. Careful underwriting is essential.

Peak: Cap rates at cycle lows, values at cycle highs. Dangerous time to buy without a significant value-add plan.

Contraction: Cap rates rising, values declining. Distressed opportunities emerge for well-capitalized buyers.

Understanding where you are in the cycle informs cap rate expectations and investment strategy.

Using Cap Rates in Negotiations

Cap rates provide negotiating leverage.

Buyer perspective: “Your asking price implies a 5.5% cap rate, but comparable properties trade at 6.5%. At market cap rates, the value is $1.2 million less.”

Seller perspective: “The market cap rate is 7%, but our tenant roster, condition, and location justify a 6.5% cap rate and higher price.”

Both arguments have merit if supported by data. Cap rate provides common analytical language for negotiation.

Cap Rate is Just One of the Numbers

What is cap rate in real estate? It’s a snapshot metric measuring unleveraged operating yield.

It’s useful for comparing properties, understanding market pricing, and quick valuation estimates.

It’s not a complete measure of investment returns. It ignores leverage, taxes, appreciation, capital expenditures, and dozens of other factors affecting actual performance.

Use the cap rate as one tool among many. Understand what it measures and what it doesn’t. Question assumptions underlying cap rate calculations. Adjust for property-specific factors.

Real estate investing requires analyzing multiple metrics, understanding market context, and exercising judgment. Cap rate provides valuable information. It doesn’t provide investment decisions.

Run the numbers. All of them. Then make informed choices.
