Capitalization rate, commonly called “cap rate,” is a metric used to compare the income-producing potential of real estate investments. Expressed as a percentage, it measures a property’s annual net operating income relative to its value or purchase price.
The formula is:
Cap rate = Annual net operating income ÷ Property value
For example, a property valued at $500,000 that generates $30,000 in annual net operating income would have a 6% cap rate.
Cap rates give investors a quick way to compare properties with different prices and income levels. They may also provide context about a property’s perceived risk and return profile.
A higher cap rate indicates that a property generates more net operating income relative to its value. However, higher cap rates may also reflect greater risk, such as an older property, weaker location, unstable occupancy, deferred maintenance, or limited growth prospects.
Lower cap rates are often associated with properties in desirable markets or with more stable income, stronger tenants, and greater expected appreciation. Neither a high nor low cap rate is inherently better. The appropriate range depends on the property, market, investment strategy, and investor’s risk tolerance.
Net operating income, or NOI, is the revenue generated by a property after applicable operating expenses are deducted.
Operating expenses may include:
NOI generally excludes mortgage payments, income taxes, depreciation, and major capital expenditures. Because those costs are not fully represented, cap rate should not be treated as the investor’s actual return.
Cap rates do not account for financing. Two investors purchasing the same property at the same cap rate may experience different cash flows based on their interest rates, leverage, amortization schedules, and loan costs.
Cap rates also do not fully capture:
Cap rates are most useful when comparing similar properties using consistent income and expense assumptions. Comparing a stabilized property’s actual NOI with another property’s projected NOI may produce a misleading result.
Cap rates can help investors evaluate single-family rental portfolios, but they should be applied carefully.
An investor may estimate the value of an SFR portfolio by dividing its combined NOI by a selected cap rate. However, the resulting portfolio value may differ from the combined market values of the individual homes.
Single-family properties are commonly valued using comparable residential sales, while commercial properties are more frequently valued based on income. Operational efficiencies created by managing a group of rental homes do not necessarily increase the appraised value of each individual property.
For that reason, an SFR portfolio should be evaluated from both perspectives:
This is particularly important when properties may eventually be sold, refinanced, or released from a portfolio loan individually.
Cap rates are a useful starting point for comparing rental properties and evaluating income relative to value. They should not serve as the sole measure of an investment’s strength.
A comprehensive analysis should also consider cash flow, financing costs, debt service coverage, capital expenditures, property condition, market fundamentals, and the anticipated holding period. Together, these factors provide a more complete view of an investment’s potential risks and returns.
