Cap Rate

Quick Definition

The capitalization rate (cap rate) is the ratio of a property's Net Operating Income (NOI) to its current market value or purchase price, expressed as a percentage. It measures the expected return on a real estate investment assuming an all-cash purchase with no debt. Cap rates are the primary metric investors use to compare real estate values and returns across different properties and markets.

Cap Rate = Net Operating Income / Property Value x 100%

What It Means

The cap rate answers one question: if you paid all cash for this property, what annual return would you earn from operations alone? A 6% cap rate means you earn 6% of the purchase price annually in operating income. It is the real estate equivalent of the earnings yield (the inverse of the P/E ratio) in stocks. A higher cap rate means a higher income return relative to price (lower valuation). A lower cap rate means a lower income return relative to price (higher valuation).

Cap Rate Formula and Example

Net Operating Income (NOI) = Gross Rental Income - Vacancy - Operating Expenses (excluding debt service)

Example: 10-unit apartment building

Cap Rates by Property Type (2025-2026)

Based on CBRE's H2 2025 Cap Rate Survey and 2026 CMBS origination data:

CBRE's H2 2025 survey found that cap rates held steady during the second half of 2025 after a period of volatility. Nearly all respondents believed the cyclical peak in yields was behind the market, though opinions were split on when compression would begin. CBRE expects cap rates for most property types to decrease by 5 to 15 basis points in 2026 as the market enters a new cycle.

The Cap Rate Spread Over Treasury Yields

The "cap rate spread" over the risk-free rate (10-year Treasury) determines how attractive real estate is relative to bonds:

Current environment (July 2026): The 10-year Treasury yield is around 4.7%. With the Fed funds rate at 3.75% and inflation at 3.5%, many premier properties are still priced at 4.5-5.5% cap rates. This creates a negative spread where the property's operating yield is below the risk-free bond yield. Investors are betting on rent growth and appreciation to compensate.

According to CRED iQ's analysis of $26.1 billion in 2026 CMBS originations, the average cap rate on newly originated collateral now sits almost exactly on top of the average mortgage coupon. This means the typical 2026 borrower is financing at roughly zero positive leverage. Multifamily, industrial, and self-storage are all borrowing through their cap rates (negative leverage), while hospitality and office are the only sectors still delivering positive leverage.

Cap Rate for Property Valuation

Investors and appraisers use cap rates to value income-producing properties:

Property Value = NOI / Cap Rate

Example: If market cap rates for similar properties are 6.5%, and a building generates $200,000 NOI:

• Property Value = $200,000 / 0.065 = $3,076,923

This works in reverse for evaluating deals:

• Offered at $4,000,000 with $200,000 NOI: cap rate = 5.0%
• Market cap rate is 6.5%: the property is overpriced relative to market

How Leverage Affects Returns

Leverage amplifies returns above the cap rate when the cost of debt is below the cap rate (positive leverage). When debt costs more than the property earns, equity returns fall below the cap rate (negative leverage).

In the current environment, many properties have negative leverage. A 5.5% cap rate property financed at 6.5% interest means the investor is paying more for debt than the property earns from operations. Sponsors are underwriting NOI growth or betting on lower refinancing rates to make the math work.

Limitations of Cap Rate

Cap rate is most useful for comparing similar properties in the same market and time period. It is one input in underwriting, not a complete investment analysis. Always use it alongside cash-on-cash return, debt service coverage ratio, and total return projections.

The 2026 Commercial Real Estate Outlook

CBRE projects a 16% increase in commercial real estate investment volume in 2026, with cap rates for most property types expected to decrease by 5 to 15 basis points. Transaction volume was up approximately 19% in 2025, and pricing has stabilized with several price indices no longer falling.

Key themes for 2026:

• Total returns will be driven by income rather than appreciation, given that benchmark rates remain elevated
• Good-quality assets are expected to see greater cap rate compression than lower-quality assets
• The refinancing wall remains large at $875 billion of commercial and multifamily maturities in 2026
• Office distress persists, with office CMBS delinquency at 11.5% as of May 2026 (down from a record 12.3% in January)
• Retail and office are expected to see notable volume growth as investors seek positive leverage

Key Points to Remember

• Cap rate = NOI / Purchase Price, measuring unleveraged operating yield
• Lower cap rate means higher valuation (like a lower earnings yield in stocks)
• Typical ranges: 4-6% for premier assets, 6-9% for secondary or value-add properties
• Used to value properties: Value = NOI / Cap Rate
• The cap rate vs. 10-year Treasury spread determines relative attractiveness; as of mid-2026, many premier properties have a negative spread
• Cap rate ignores financing, appreciation potential, and capital expenditure needs; always use alongside other metrics

Common Mistakes to Avoid

• Comparing cap rates across different markets without context: A 5% cap rate in Manhattan and a 5% cap rate in a tertiary market mean very different things. The risk profiles, rent growth prospects, and liquidity are completely different.
• Ignoring capital expenditures: A property with a 7% cap rate that needs a new roof, HVAC replacement, and parking lot repaving next year may have a true cap rate closer to 5% after accounting for those costs.
• Assuming cap rates will stay constant: If you buy at a 5% cap rate and market cap rates rise to 6%, your property value drops by approximately 17% even if NOI is unchanged. Cap rate movement is a major source of real estate risk.
• Using NOI at face value: Some sellers inflate NOI by underreporting vacancy, deferring maintenance, or excluding management fees. Always verify NOI against actual operating statements and tax returns.
• Forgetting about negative leverage: In the current rate environment, borrowing at 6.5% to buy a property yielding 5.5% means you are losing money on every dollar of debt. This only works if rents grow fast enough to offset the gap.

Frequently Asked Questions

Q: Is a higher or lower cap rate better? A: It depends on your goal. A higher cap rate means more current income relative to price, which is better for current yield and income investors. A lower cap rate means you are paying more for each dollar of income, typically associated with higher-quality, lower-risk assets in prime markets with stronger appreciation potential. Neither is universally better; it depends on investment strategy, financing, and market expectations.

Q: What is cap rate compression? A: Cap rate compression occurs when investor demand pushes property prices up faster than rents increase, shrinking the cap rate over time. A property generating $100,000 NOI was worth $1.5M at a 6.7% cap rate. If increased demand pushes its price to $2M, the cap rate compresses to 5.0%. Cap rate compression benefits existing owners through appreciation but makes it harder for new buyers to find attractive returns.

Q: How does leverage affect returns vs. the cap rate? A: Leverage amplifies returns above the cap rate when the interest rate is below the cap rate (positive leverage). In the current environment, many properties have negative leverage: debt costs more than the property earns. A 5.5% cap rate property financed at 6.5% produces equity returns below 5.5%. Sponsors underwriting these deals are betting on NOI growth or lower future refinancing rates.

Q: What is happening with cap rates in 2026? A: CBRE's H2 2025 survey found cap rates held steady, with most professionals believing the cyclical peak in yields is behind the market. CBRE expects 5-15 basis points of compression in 2026 for most property types. However, the refinancing wall ($875 billion in maturities) and elevated Treasury yields (around 4.7%) mean compression will be selective, hitting quality assets first rather than being a broad repricing rally.
