Cap Rates: Ultimate Real Estate Investing Guide
By Adam Gower Ph.D.
A cap rate (capitalization rate) in real estate equals Net Operating Income divided by property value: Cap Rate = NOI ÷ Value. A property generating $500,000 NOI purchased for $10 million has a 5% cap rate. Current market cap rates range from 4.5-6.5% for multifamily, 5-7% for industrial, and 6-9% for office. Lower cap rates mean higher prices relative to income; higher cap rates mean lower prices.
Cap rates are one of the first numbers sponsors see on an offering memorandum and, having analyzed thousands of deals over more than 30 years, I have found that cap rate is useful precisely because it is simple. It allows you to compare income-producing properties on an unlevered basis, regardless of capital structure or financing assumptions. That simplicity is also its limitation. Cap rate tells you nothing about debt terms, nothing about future rent growth, and nothing about capital expenditure requirements.
For sophisticated sponsors is a valuation shorthand that must be interpreted inside a broader underwriting framework. Understanding how cap rates are calculated, what drives them by property type and market, and how they interact with interest rates is fundamental to acquisition pricing, exit assumptions, and investor communication.
This guide explains cap rates from a sponsor’s perspective. We focus on how to calculate them correctly, what current market ranges actually look like, how to use them in underwriting, and where they fail. The goal is not to simplify cap rates for beginners, but to make them operational for real investment decisions.
Key Takeaways
- Cap rate formula: NOI ÷ Property Value so a 5% cap rate means you're paying 20x annual NOI for the property
- Current multifamily cap rates range 4.5-6.5%, industrial 5-7%, office 6-9%, and retail 6-8.5% depending on quality and location
- Lower cap rate = higher price; higher cap rate = lower price
- Cap rate excludes financing; it's an unlevered, property-level metric; cash-on-cash return measures levered equity returns
- Interest rates influence cap rates with a typical 150-250 basis point spread between cap rates and borrowing costs
- Exit cap rate assumptions drive IRR where, for example, a 50 basis point increase in exit cap rate can reduce projected IRR by 200+ basis points
- Pro forma cap rates differ from trailing so always verify seller's cap rate assumptions against actual operating history

What Is a Cap Rate in Real Estate?
The capitalization rate, or cap rate, is defined as Net Operating Income divided by property value or purchase price:
Capitalization rate = NOI ÷ Property Value
If a property produces $500,000 in annual NOI and trades for $10 million, the cap rate is 5 percent. The relationship also works in reverse. Value equals NOI divided by cap rate, which is why cap rate functions as a pricing mechanism as much as a return metric:
Value = NOI ÷ Cap Rate
Cap rate measures the unlevered return of a property based solely on its current income. It strips out financing and focuses on the asset itself and, consequently, why it remains one of the most common valuation metrics in commercial real estate and a core input alongside other valuation methods.
What cap rate tells you is how aggressively the market is pricing a stream of income. A lower cap rate means investors are willing to pay more for each dollar of NOI. A higher cap rate means they demand a higher yield to own that income.
What cap rate does not tell you is equally important. It does not account for debt structure, future rent growth, lease rollover risk, capital expenditures, or changes in market conditions. It is a snapshot based on a single year of income.
How to Calculate Cap Rate
The Basic Formula
Cap rate is calculated using a simple ratio:
Cap Rate = Net Operating Income ÷ Property Value
If a property generates $500,000 in annual NOI and is purchased for $10,000,000, the calculation is:
$500,000 ÷ $10,000,000 = 0.05, or a 5.0 percent cap rate
You can also work backward from a target cap rate to estimate value. If a property produces $500,000 of NOI and market pricing implies a 5 percent cap rate, the implied value is:
$500,000 ÷ 0.05 = $10,000,000
This is how cap rates function in practice as a valuation shortcut. Markets price income, and the cap rate expresses how much investors are willing to pay for each dollar of NOI.
Calculating NOI Correctly
The reliability of any cap rate depends entirely on the accuracy of the NOI used in the calculation. NOI starts with Gross Potential Rent, then adjusts for vacancy and other income, and subtracts operating expenses.
Gross Potential Rent:
-> Minus: Vacancy allowance, typically 5 to 10 percent depending on asset class and market
-> Plus: Other income such as parking, laundry, or reimbursements
-> Minus: Operating expenses including property management, repairs and maintenance, insurance, utilities, and real estate taxes
NOI explicitly excludes debt service, capital expenditures, depreciation, and income taxes. These items affect cash flow to equity but do not belong in NOI.
Common errors include using projected rent instead of in-place rent, underestimating vacancy, capitalizing one-time income items, and excluding recurring expenses such as repairs or management fees. Brokers often present “stabilized” NOI that assumes rent growth and expense efficiencies that have not yet been achieved. For underwriting, actual operating history should always be the starting point.
Trailing vs. Pro Forma Cap Rate
A trailing cap rate is based on historical NOI, typically the last twelve months of actual operations. It reflects what the property is earning today.
A pro forma cap rate is based on projected stabilized NOI after lease-up, renovations, or operational improvements. It reflects what the property is expected to earn in the future.
The same property can show very different cap rates depending on which NOI is used. A value-add asset may appear to trade at a low trailing cap rate but a higher pro forma cap rate once improvements are complete.
Going-in cap rate refers to the cap rate at acquisition based on current or near-term NOI. Exit cap rate refers to the assumed cap rate used to estimate value at sale. Underwriting depends heavily on the spread between these two numbers. Using an aggressive pro forma cap rate or assuming the exit cap rate will match or be much lower than the going-in cap rate is one of the most common sources of valuation error.
What Is a Good Cap Rate?
There is no universally “good” cap rate. A cap rate is only meaningful relative to property type, market, and risk profile. A 4.5 percent cap rate can be rational for a Class A multifamily asset in a high-growth metro, while a 7.5 percent cap rate may be inadequate compensation for an aging office building in a declining market. What matters is whether the cap rate properly reflects the income durability and risk embedded in the asset.
Cap Rates by Property Type (Current Market)
While the following can vary according to where we are in any given economic cycle, their relative differences often stay the same:
- Multifamily: 4.5 to 6.5 percent
- Industrial: 5.0 to 7.0 percent
- Office: 6.0 to 9.0 percent depending on tenant quality and location
- Retail: 6.0 to 8.5 percent depending on format and lease structure
These ranges align with national brokerage data reported in CBRE’s U.S. Cap Rate Survey, which describes cap rate difference across asset classes.
Multifamily and industrial assets continue to trade at lower cap rates because they benefit from stronger demand fundamentals and deeper capital markets. Office trades at higher yields due to leasing uncertainty and elevated rollover risk. This pattern is reflected in current brokerage outlooks such as CBRE’s property-type cap rate analysis in its U.S. Real Estate Market Outlook.
Ranges vary within each property type because cap rates price risk, not just income. A newly built industrial facility leased to a national tenant on a long-term contract will trade at a materially lower cap rate than an older warehouse with short leases and higher capital expenditure risk.
Cap Rates by Market Tier
Market classification also drives cap rate expectations. Marcus & Millichap’s Research Brief: Investor Insights reports materially higher cap rates outside primary gateway metros and that gateway markets such as New York, Los Angeles, and San Francisco typically trade at lower cap rates because of higher liquidity, greater institutional demand, and long-term population and employment density. Secondary markets tend to show moderate cap rates that balance growth potential with reduced pricing competition. Tertiary markets generally offer higher cap rates because they carry thinner buyer pools and higher exit risk.
Market-level pricing differences are visible in brokerage transaction data such as Marcus & Millichap’s regional cap rate reporting, which shows systematic yield separation between primary and non-primary metros in its National Investment Forecast.
This structure reflects a basic risk and return tradeoff. Lower cap rates signal stronger perceived income durability. Higher cap rates signal that investors require more yield to compensate for uncertainty in demand, liquidity, or tenant stability.
What Drives Cap Rate Variation
Several variables determine where a specific asset falls within a cap rate range.
- Property quality matters. Class A buildings generally trade at lower cap rates than Class B or Class C assets because they require less near-term capital and attract stronger tenants.
- Lease term and tenant credit matter. Long-term leases to creditworthy tenants compress cap rates. Short lease durations or weak tenant credit expand them.
- Location and submarket matter. Assets in prime corridors with supply constraints command lower cap rates than similar properties in fringe locations.
- Physical condition and age matter. Deferred maintenance, functional obsolescence, and near-term capital requirements push cap rates higher.
- Market supply and demand dynamics matter. Oversupplied markets or sectors facing structural demand shifts require higher yields to clear.
A “good” cap rate is therefore not a single number. It is a judgment about whether the price of income adequately compensates the investor for the combined risks of the property, the tenant base, and the market environment.
The Relationship Between Cap Rates and Interest Rates
The Spread That Matters
The relationship between cap rates and interest rates is best understood through the spread between property yield and borrowing cost where cap rate minus borrowing cost equals the spread.
Historically, stabilized commercial real estate has traded at a spread of roughly 150 to 250 basis points over long-term borrowing costs. This spread compensates investors for illiquidity, operating risk, and capital expenditure exposure. When that spread compresses, pricing becomes fragile. When it widens, values reset downward.
Spread behavior explains why leverage can either enhance or destroy returns. If your cap rate is higher than your interest rate, leverage is positive. If your borrowing cost exceeds the cap rate, leverage becomes negative and equity returns deteriorate even if operations are stable. This is why underwriting must explicitly model the interaction between debt and property yield, not treat them as independent variables. We address this interaction directly when analyzing financing and cap rates in complex capital structures.
Spreads compress when capital is abundant and lenders compete aggressively on pricing. They expand when rates rise, credit tightens, or uncertainty increases. Negative leverage appears most often in transition periods when cap rates lag changes in the cost of capital.
How Rising Rates Affect Cap Rates
In theory, rising interest rates should push cap rates higher, which in turn reduces property values. Higher borrowing costs increase required returns, and higher required returns reduce the price investors are willing to pay for a given stream of NOI.

In reality, the adjustment is not immediate. Cap rates respond with lag because transactions reprice slowly and sellers resist marking assets down. During the 2022 to 2024 rate cycle, the Federal Reserve raised policy rates aggressively as shown in its Federal Funds Rate data. Borrowing costs moved first. Cap rates followed later and unevenly by property type and market.
Multifamily and industrial cap rates expanded modestly as rent growth partially offset higher rates. Office cap rates expanded sharply because demand uncertainty compounded the impact of higher financing costs and the continuing after-effects of work-from-home trends post Covid. Transaction volume collapsed before pricing fully adjusted, illustrating that liquidity dries up before values stabilize.
Looking forward, the key variable is not just the absolute level of rates but the direction and volatility of borrowing costs. Stable rates allow cap rates to settle into new equilibrium ranges. Rapid rate movements increase spread uncertainty and suppress deal activity. For underwriting, this means exit cap assumptions should be conservative when rate policy is unstable and should not assume a return to prior-cycle pricing without structural justification.
Cap Rate vs. Other Return Metrics
Cap rate is often the first metric cited in a deal summary, but it is only one of several return measures that matter to sponsors and investors. To interpret it correctly, it must be viewed in relation to leverage, hold period, and position in the capital stack.
Cap Rate vs. Cash-on-Cash Return
Cap rate is an unlevered, property-level metric. It expresses NOI as a percentage of property value and ignores financing entirely.
Cash-on-cash return is a levered, equity-level metric. It measures annual cash flow distributed to investors pro-rata to their invested equity.
Each matters at a different stage of analysis. Cap rate is useful for comparing assets across markets and property types on a common, unlevered basis. Cash-on-cash return is useful for evaluating how a specific capital structure converts property income into investor distributions.
Leverage is the bridge between the two. When borrowing costs are below the cap rate, leverage can increase cash-on-cash returns. When borrowing costs exceed the cap rate, leverage becomes negative and reduces equity performance. This is why cap rate alone cannot predict investor returns without understanding the financing terms layered on top of the asset.
Cap Rate vs. IRR
Cap rate is a snapshot of a single year’s income relative to value. It assumes a static condition and does not incorporate changes in rent, expenses, or value over time.
Internal rate of return, or IRR, measures rate of return over the entire hold period. It captures operating cash flow, changes in NOI, and the sale price at exit. When comparing cap rate to total return metrics like IRR, industry practitioners emphasize that cap rate is a static snapshot rather than a comprehensive performance measure.
“The unlevered IRR is a much better metric of value than is a cap rate, because a cap rate is very static.”
IRR matters more for value-add and development strategies because these investments are driven by income growth and capital appreciation rather than current yield. In those cases, the going-in cap rate is often less important than the exit cap rate used to estimate terminal value.
Exit cap rate has a direct mechanical effect on IRR. A higher assumed exit cap rate lowers terminal value and reduces projected returns. A lower exit cap rate increases terminal value and inflates IRR. This sensitivity is why conservative underwriting typically assumes some degree of cap rate expansion rather than relying on market compression.
Cap Rate vs. Yield
Cap rate is based on current or near-term NOI. Yield is a broader concept that can describe income relative to cost under different assumptions.
Current yield refers to the income generated by an asset today relative to its price, similar in concept to cap rate but often used in bond or portfolio contexts.
Stabilized yield refers to income once a property reaches normalized occupancy and expense levels. This is often used for assets in lease-up or transition.
Development yield, also called yield on cost, measures stabilized NOI as a percentage of total development cost. It answers a different question than cap rate. It shows how efficiently capital is converted into income, not what the market will pay for that income at exit.
Each metric serves a different purpose. Cap rate is a pricing lens. Cash-on-cash return is a distribution lens. IRR is a total return lens. Yield on cost is a capital efficiency lens. Confusing them leads to mispricing risk and misaligned investor expectations.
Using Cap Rates for Investment Decisions
Cap rates become actionable only when they are tied to underwriting decisions. For sponsors, they influence how aggressively you price acquisitions, how conservatively you model exits, and how you frame projected returns relative to investor return expectations.
Acquisition Pricing
The practical question is not “what is the market cap rate,” but what cap rate you should pay for a specific asset given its risk profile.
Market cap rates provide a reference point. Deal-specific cap rates should adjust for property condition, lease structure, tenant credit, capital expenditure requirements, and submarket positioning. A stabilized Class A property with long-term leases can justify cap rates below the market average. A value-add property with short leases and deferred maintenance should trade at a higher cap rate than the headline market number.
Paying below market cap rate is rational only when the income stream is more durable than the market average. That durability may come from superior location, stronger tenants, or contractual rent growth. Paying below market simply because capital is available is a pricing error, not a strategy.
Warning signs in a seller’s cap rate presentation usually appear in the NOI. Common red flags include reliance on unachieved “stabilized” rents, omission of recurring expenses, aggressive vacancy assumptions, or the inclusion of one-time income items. These tactics inflate NOI and create the illusion of a lower cap rate. Sound acquisition pricing begins by recalculating NOI using conservative, verifiable inputs.
Exit Assumptions
Exit cap rate is the most powerful variable in a pro forma because it determines terminal value. Small changes in this assumption have outsized effects on projected IRR.
A conservative practice is to assume some degree of cap rate expansion at exit rather than underwriting a flat or lower exit cap rate. If the exit cap rate is 50 basis points higher than the going-in cap rate, the implied value of the property declines materially even if NOI grows. In many models, that shift alone can reduce projected IRR by 200 basis points or more.
Sensitivity analysis is therefore essential. Sponsors should test multiple exit cap scenarios to understand how exposed returns are to valuation risk. If a deal only works at the most optimistic exit cap assumption, the risk is embedded in the structure, not just the market.
Comparing Investment Opportunities
Cap rates can help compare opportunities, but only after normalizing for differences in risk and structure.
Two assets with identical cap rates may carry very different risk profiles if one has long-term leases and the other faces near-term rollover. Normalization requires adjusting for lease term, tenant quality, market liquidity, and capital requirements.
Risk-adjusted cap rate analysis reframes the question from “which deal has the higher cap rate” to “which deal offers the best compensation for its specific risks.” A higher cap rate does not automatically mean a better investment. It may simply reflect higher uncertainty in income, weaker tenant demand, or more volatile exit pricing.
Cap rate is therefore not a ranking tool by itself. It is a lens for evaluating whether price aligns with risk. Used properly, it disciplines acquisition decisions and forces explicit assumptions about how value will be created and preserved.
Cap Rate Compression and Expansion
Cap rate movement reflects how investors price risk and income over time. Compression means investors accept lower yields for the same income stream. Expansion means they demand higher yields to compensate for higher capital costs or weaker income certainty.
What Drives Compression
Cap rate compression occurs when required returns fall and competition for assets increases.
Low interest rates reduce borrowing costs and increase the amount investors can pay for income. During the 2010 to 2021 cycle, falling rates supported sustained compression across most property types. At the same time, global capital flows into U.S. real estate increased as investors sought yield relative to bonds and equities.
Strong operating fundamentals reinforce this effect. Rent growth and low vacancy reduce perceived income risk, allowing investors to accept lower yields. This dynamic was most visible in multifamily and industrial assets with durable demand drivers.
Flight to quality accelerates compression in top-tier assets. In uncertain environments, capital concentrates in properties with strong tenants, long leases, and prime locations, pushing cap rates lower for Class A assets even when broader markets soften.
What Drives Expansion
Cap rate expansion occurs when required returns rise or income certainty deteriorates.
Rising interest rates increase borrowing costs and raise investor return thresholds. Economic uncertainty adds risk premiums to underwriting assumptions.
Property type disfavor magnifies the effect. Office was the clearest post-Covid example. Demand uncertainty, lease rollover risk, and structural changes in workplace i.e. work-from-home have forced cap rates higher as buyers reassess long-term income durability.
Oversupply can also drive expansion. Markets with heavy new construction relative to demand experience downward pressure on rents and higher vacancy, which pushes investors to reprice assets at higher cap rates to compensate for weaker fundamentals.
Common Cap Rate Mistakes
Cap rates are simple to calculate and easy to misuse. The most costly errors come from treating them as objective facts rather than as outputs of assumptions about income, risk, and market conditions.
Using Broker’s Pro Forma Uncritically
Pro forma cap rates are often built on optimistic assumptions rather than demonstrated performance. “Stabilized” NOI frequently assumes rent growth that has not yet occurred, expense reductions that are not yet proven, and vacancy levels that are better than historical experience.
A common failure is to underwrite based on projected NOI while ignoring trailing actuals. This shifts risk from the model to the sponsor without compensation. In practice, the broker’s pro forma should be treated as a hypothesis, not a result. Always reconcile projected NOI against historical operating statements to determine what portion of the cap rate is earned and what portion is aspirational.
If the pro forma requires perfect execution to justify the purchase price, the cap rate is not describing value. It is describing hope.
Ignoring Cap Rate Expansion Risk
Another frequent mistake is assuming the exit cap rate will equal the going-in cap rate. This embeds an implicit bet that market pricing will not deteriorate over the hold period.
Cap rate expansion has a mechanical effect on value. A 100 basis point increase in exit cap rate can materially reduce terminal value even if NOI grows. In many underwriting models, that shift alone is enough to erase most of the projected upside.
Sensitivity analysis should explicitly test how changes in exit cap rate affect value and IRR so that valuation risk is visible rather than hidden in a single-point assumption.
Comparing Apples to Oranges
Cap rates are only comparable if the underlying NOI is calculated the same way. In practice, it often is not.
Some sellers present trailing NOI. Others present forward or stabilized NOI. Some include management fees. Others exclude them. Some capitalize recurring repairs. Others treat them as non-recurring. These differences can change the apparent cap rate without changing the economics of the asset.
Property condition also distorts comparisons. A newly renovated building and a deferred-maintenance building can show the same cap rate on paper while implying very different future capital needs.
Comparing cap rates without normalizing NOI methodology and property condition leads to false conclusions. A higher cap rate does not necessarily mean a better deal. It may simply reflect more aggressive assumptions, weaker income quality, or higher future costs.
The common thread across these mistakes is mistaking a calculated ratio for an independent signal. Cap rate is not an input. It is a result. If the inputs are wrong, the cap rate will be misleading, regardless of how precise the math appears.
Frequently Asked Questions
A good cap rate depends on property type, market, and risk profile. A 5 percent cap rate may be appropriate for a stabilized multifamily property in a strong metro, while an 8 percent cap rate may be required for a small rental property in a weaker market with higher vacancy and turnover risk. The cap rate must compensate for income durability, tenant quality, and local demand conditions rather than meet a universal benchmark.
Closing
Cap rate is one of the most important tools in real estate analysis, but it is not a complete answer by itself. It establishes a relationship between income and price, but it does not account for financing, future growth, or capital needs.
Used correctly, cap rate is a disciplined way to think about valuation and risk. Used alone, it can obscure more than it reveals. Sponsors who understand how cap rates interact with underwriting assumptions, interest rates, and exit pricing make better acquisition decisions and communicate more clearly with investors.
Mastering cap rate analysis is not about memorizing ranges. It is about knowing what drives them and when they break. GowerCrowd’s resources are designed to help sponsors apply these metrics in real capital-raising and underwriting decisions, not just describe them in theory.
