Capitalization Rate (CAP rate)

The Capitalization Rate (CAP rate) is a key metric in real estate investments, representing the rate of return on a property based on the income it generates. It’s calculated as:

NOI

This is the annual income generated by the property after deducting all operating expenses — and property taxes and insurance are operating expenses, already inside NOI — but before income taxes and financing costs. Leaving the property-tax bill out of NOI is the most common way this number gets overstated. Think of NOI as the property’s “salary” before income taxes.

Current Market Value

This is the present value of the property in the market. It can be determined through appraisals or comparable sales or you just know it when consider purchase.

Suppose you have a property with an NOI of $100,000 and a market value of $1,000,000:

Using CAP Rate for Comparison:

Risk Assessment

Higher CAP rates typically indicate higher risk and potentially higher returns, while lower CAP rates suggest lower risk and more stable income. For instance, a property in a prime location might have a CAP rate of 5%, indicating lower risk, whereas a property in a developing area might have a CAP rate of 10%, indicating higher risk. An ROI of 3% is generally acceptable in areas with long-term, responsible tenants. However, in areas with high tenant turnover, a 3% ROI might not suffice.

Market Comparison

Compare properties within the same market. If Property A has a CAP rate of 8% and Property B has a CAP rate of 6%, Property A might seem more attractive. However, consider why the CAP rate differs — Property A might be in a less desirable location or require more maintenance.

Investment Strategy

Align the CAP rate with your investment goals. If you seek steady income, opt for properties with lower CAP rates. If you’re willing to take on more risk for higher returns, higher CAP rates might be your target.

Research by Geltner and Miller (2006) in Commercial Real Estate Analysis and Investments¹⁴¹ shows a correlation between CAP rates and perceived risk in real estate markets. Studies like those by CBRE (2023) indicate that CAP rates fluctuate with economic conditions, interest rates, and market demand.

Adjust for Market Conditions

CAP rates can vary with economic cycles. During a recession, CAP rates might increase as property values drop and risks rise.

Consider Future NOI

Look at potential changes in NOI due to market trends, lease renewals, or property improvements.

Use in Conjunction with Other Metrics

While CAP rate is useful, also consider metrics like Cash-on-Cash Return, IRR (see section “Internal Rate of Return (IRR)”), and Gross Rent Multiplier (GRM) for a comprehensive analysis.
