A capitalization rate, commonly called a cap rate, is a property-level ratio used to compare net operating income with property value. It is a screening and comparison tool, not a promise of investment return.
Cap rate = annual net operating income / property value
Net operating income, or NOI, generally starts with property income and subtracts ordinary operating expenses. Financing payments, income taxes, depreciation, and owner-specific capital structure are usually analyzed separately. The Office of the Comptroller of the Currency's Commercial Real Estate Lending handbook discusses capitalization rates within broader commercial real estate valuation and underwriting.
There is no universal cap rate that is good for every property. A useful cap rate must be interpreted alongside the asset type, lease terms, tenant concentration, location, physical condition, operating history, expected capital needs, and the quality of the income and expense data.
A lower cap rate can reflect stronger demand or lower perceived risk, but it can also mean that a buyer is paying more for each dollar of current NOI. A higher cap rate can signal a lower acquisition price relative to NOI, but it may also reflect vacancy, deferred maintenance, lease rollover, market volatility, or other risk. The ratio identifies a relationship; it does not explain the relationship by itself.
Assume a property has verified annual NOI of $50,000 and a value of $1,000,000. Dividing $50,000 by $1,000,000 produces a 5% cap rate.
That example does not mean the investor will earn 5%. Actual performance can differ because of financing costs, capital expenditures, leasing costs, changes in occupancy, unplanned repairs, sale price, taxes, and other property-specific factors.
The formula is simple; the inputs require discipline. Before relying on NOI, review:

Cap rate can help compare properties on a consistent current-income basis, but a complete review also considers debt terms, cash flow timing, reserves, capital improvements, lease rollover, market rents, exit assumptions, and downside scenarios. Owners should document the source and date of every input so that changes in the analysis can be traced.
Cap rate is most useful when it opens these questions rather than closes them.
A property management review can help an owner test rent-roll accuracy, expense controls, maintenance exposure, reporting quality, and the operating assumptions behind NOI. Request a property management review to discuss the property-specific facts that should be examined.
