Direct Answer
Commercial real estate (CRE) generates returns through rental income and property appreciation from office, retail, industrial, multifamily, and hospitality assets. Net operating income (NOI) divided by purchase price gives the cap rate, the primary valuation metric. Leverage amplifies both returns and losses, and lease structure, tenant credit, and exit cap rate assumptions are where most valuation errors are made.
Commercial Real Estate: NOI and Cap Rate
How commercial real estate generates returns
Commercial real estate produces two components of return: current income from rent, and value appreciation (or depreciation) over the holding period. Unlike residential real estate, which is often owner-occupied and valued based on comparable sales, commercial property value is derived primarily from its income-producing capacity. A property worth owning is one whose income stream justifies its price, adjusted for risk.
Property types include office, retail, industrial and logistics, multifamily residential (apartment buildings), hospitality (hotels and motels), self-storage, and data centers. Each sector has different demand drivers, lease structures, tenant profiles, and sensitivity to economic cycles. Industrial and logistics properties benefited from e-commerce growth; traditional retail and central-business-district office have faced secular and cyclical headwinds simultaneously.
NOI and cap rate mechanics
Net operating income (NOI) is the income a property generates after paying all operating expenses but before debt service, depreciation, and income taxes. The formula is: NOI = Gross rental income − vacancy allowance − operating expenses (management fees, insurance, property taxes, maintenance, utilities). NOI does not deduct mortgage interest or principal payments. It is the property's income before financing.
The capitalization rate, or cap rate, is NOI divided by property value. If a property generates $500,000 NOI and sells for $10,000,000, its cap rate is 5%. Cap rate is used to compare properties and to convert a known income stream into an implied value. Rearranging: Property value = NOI / cap rate. A higher cap rate means either lower price for the same income, or the market demands more return because the asset is riskier. Rising interest rates tend to push cap rates up (and property values down) because the spread between cap rates and borrowing costs needs to remain attractive to investors.
Leverage, debt service coverage, and loan-to-value
Most commercial real estate is purchased with debt. The loan-to-value ratio (LTV) measures how much of the purchase price is financed. A 65% LTV means the borrower puts up 35% equity and borrows 65%. Leverage amplifies equity returns in a rising market and amplifies losses in a declining one.
Lenders focus on the debt service coverage ratio (DSCR): NOI divided by annual debt service (principal and interest). A DSCR of 1.25 means NOI covers 125% of debt payments, providing a 25% cushion before the property cannot service its debt. Lenders typically require DSCR of at least 1.20 to 1.25 at origination. If NOI falls because of vacancies, rent concessions, or rising operating costs, DSCR can drop below 1.0, triggering loan covenants or default risk.
Commercial mortgages differ from residential mortgages in structure. They typically have balloon payments at maturity (5-10 years), requiring refinancing. Interest rates reset at refinancing, which creates significant risk when rates rise sharply between origination and maturity.
Lease structures and their implications
CRE leases vary significantly in how operating expenses are allocated between landlord and tenant. In a gross lease, the landlord pays all operating expenses out of the rent received. In a net lease, the tenant pays some or all operating expenses directly. Triple-net (NNN) leases have the tenant pay property taxes, insurance, and maintenance. From the landlord's perspective, an NNN lease provides more predictable NOI but transfers operating decisions to the tenant and means the landlord is more exposed to the tenant's creditworthiness.
Lease term and renewal options matter for income stability. A long-term lease with a creditworthy tenant (called a credit tenant) is valued differently from a month-to-month tenancy. Sale-leaseback transactions, where a company sells its property and immediately leases it back, are a way to monetize real estate while retaining operational use, and they concentrate tenant credit risk in one counterparty.
Vacancy, tenant credit, and operating assumptions
A 100% occupied building is not automatically better than one with 90% occupancy. Below-market leases at high occupancy can make a property worth less than a partially vacant building with rents at current market. Underwriting must use market rents at lease expiration, not current below-market rents, to avoid overpaying based on temporary income.
Tenant credit quality determines whether the lease income stream is reliable. A lease with a nationally rated retailer and 15 years remaining is valued differently than the same rent from a small local business on a 1-year lease. Tenant concentration risk (one tenant generating most of the NOI) creates a binary outcome if that tenant vacates.
Exit cap rate: where CRE underwriting often breaks
Most CRE investments are valued using a discounted cash flow model that requires an assumed sale price at the end of the holding period. That sale price is calculated by applying an exit cap rate to the projected NOI in the sale year. Exit cap rate assumption is a critical input: a 50-basis-point change in the exit cap rate on a $10M NOI property changes the exit value by roughly $8-10M at typical cap rate ranges. Optimistic exit cap rate assumptions built into a base case underwriting can make a marginal investment appear attractive. Stress-testing the exit cap rate 50 to 100 basis points above the entry cap rate is standard practice in conservative underwriting.
Frequently Asked Questions
Is commercial real estate an inflation hedge?
It can be, but the relationship is conditional. Leases with rent escalation clauses tied to CPI can pass inflation to tenants, and replacement cost of buildings rises with construction costs, supporting long-run property values. However, short-term inflation driven by rising interest rates can hurt CRE values because cap rates rise with borrowing costs. Properties with near-term lease expirations in strong rental markets fare better during inflation than properties with long-term fixed-rate leases that cannot reprice. The inflation hedge property of CRE is a structural tendency over long holding periods, not a reliable near-term return driver.
What is a good cap rate?
There is no universally good cap rate. Cap rates reflect the required return for a specific asset in a specific market at a specific point in time. A 4% cap rate on a Class A multifamily asset in a high-demand coastal market may be appropriate given rent growth expectations. A 4% cap rate on an older suburban office building with significant near-term lease rollover is probably too low given the risk. Cap rates must be evaluated relative to comparable transactions, current financing rates (the spread between cap rate and borrowing cost), local market conditions, and the specific risk profile of the asset and its tenancy. A low cap rate signals either high-quality income or an overpriced asset; the difference requires analysis.
Why do higher interest rates hurt CRE values?
Commercial real estate values are primarily driven by the income the property produces relative to the required return. When risk-free rates rise, investors require higher returns on all assets, including real estate. This pushes cap rates up. Since property value equals NOI divided by cap rate, the same NOI is worth less at a higher cap rate. Additionally, higher rates increase the cost of debt financing, reducing the equity returns achievable through leverage and making leveraged CRE deals less attractive. Properties with near-term debt maturities face refinancing at materially higher rates, which can impair cash flow and trigger covenant breaches.
Is 100% occupancy always better?
Not necessarily. Full occupancy at rents significantly below current market rates can produce lower value than partial occupancy at market rents, depending on lease terms and the cost to reposition. A property 100% leased at rents that are 30% below market on 10-year leases may be worth less than a comparable property with 80% occupancy at current market rents, because the upside to market rents is locked out for a decade. Sophisticated underwriting evaluates the mark-to-market opportunity at lease expiration, not just current occupancy, to assess embedded value.
How is direct CRE different from a REIT?
A real estate investment trust (REIT) is a publicly traded or private company that owns income-producing real estate and passes most of its taxable income to shareholders as dividends. Direct CRE ownership means holding the property directly or through a private partnership. REITs offer liquidity, diversification, lower minimum investment, and professional management, but they trade like stocks and their prices fluctuate with market sentiment, often moving more than the underlying real estate value. Direct CRE offers greater control, potential tax benefits (depreciation, 1031 exchanges), and insulation from public market volatility, but requires significant capital, expertise, and active management, with illiquidity that can extend to years.
