ExamPassCapitalization Rate in Commercial Real Estate
A capitalization rate (cap rate) is the ratio of a commercial property's net operating income (NOI) to its value or price, written as a percentage: cap rate equals net operating income divided by value. It is used to estimate what an income-producing property is worth, to compare one investment with another, and to gauge risk and return. A higher cap rate generally means a lower price relative to income, and often higher perceived risk; a lower cap rate means a higher price relative to income, and often lower perceived risk. The same formula, rearranged, turns a known income and a market cap rate into an estimate of value.
| Cap rate | What it usually signals |
|---|---|
| Higher cap rate | A lower price per dollar of income, often higher risk |
| Lower cap rate | A higher price per dollar of income, often lower risk |
What is a capitalization rate?
A cap rate expresses how much income a property produces relative to its price. If a property generates a certain net operating income each year, and it is worth a certain value, the cap rate is that income divided by that value. Because it strips a deal down to income versus price, the cap rate lets investors compare very different properties on a common measure, and lets appraisers and registrants estimate value from income.
What is net operating income (NOI)?
Net operating income is the income a property produces after its operating expenses but before financing. You start with the gross income the property can earn, from rents and other sources, subtract a realistic vacancy allowance and the operating expenses needed to run the building, such as property taxes, insurance, maintenance, utilities, and management, and the result is NOI. Crucially, NOI excludes mortgage payments and other financing costs, because the cap rate measures the property's performance, not the owner's particular loan.
How do you use a cap rate to value a property?
The formula rearranges. If cap rate equals NOI divided by value, then value equals NOI divided by cap rate. So when you know a property's NOI and you can observe the cap rate that similar properties are trading at, you can estimate value by dividing the income by the market cap rate. This income approach is central to commercial valuation, where a building is worth what its income stream is worth to a buyer.
What does a higher or lower cap rate tell you?
A higher cap rate means an investor is paying less for each dollar of income, which usually reflects higher risk, a weaker location, or less certain income, and it pushes value down. A lower cap rate means an investor is paying more for each dollar of income, usually reflecting lower risk, a stronger location, or more dependable income, and it pushes value up. Reading a cap rate is therefore reading the market's view of risk and quality, not just a number.
How do you calculate a cap rate step by step?
Suppose a small retail plaza earns gross income of 240,000 dollars a year, and its vacancy allowance and operating expenses together come to 86,000 dollars a year. Its net operating income is 240,000 minus 86,000, or 154,000 dollars. If comparable plazas in the area trade at a cap rate of about 7 per cent, you can estimate the plaza's value as NOI divided by the cap rate, or 154,000 divided by 0.07, which is roughly 2,200,000 dollars. If buyers were willing to accept a lower cap rate of 6 per cent, the same income would support a higher value of about 2,567,000 dollars, which shows how a lower cap rate raises value. These figures are illustrative, a real cap rate comes from current market evidence, and this is educational information about a method, not investment advice.
How does the commercial exam test cap rates?
Questions usually give you two of the three quantities, namely income, value, and cap rate, and ask for the third, or they ask what happens to value when the cap rate moves. The traps are forgetting that NOI excludes financing, or reversing the relationship so that a higher cap rate is wrongly taken to mean a higher value. Anchor on value equals NOI divided by cap rate.
