Cap Rate Guide for Real Estate Investors
The capitalization rate — or cap rate — is the foundational metric of commercial and residential real estate investment. It tells you the rate of return a property would generate if purchased entirely with cash, making it the purest measure of a property's income potential independent of how it is financed.
Cap Rate Formula
Cap Rate = Net Operating Income (NOI) ÷ Current Market Value × 100
Or rearranged to find property value: Value = NOI ÷ Cap Rate
And to find required NOI: NOI = Value × Cap Rate
What Is NOI?
Net Operating Income = Gross Rental Income − Vacancy − Operating Expenses (taxes, insurance, management, maintenance, utilities). It does NOT include mortgage payments, depreciation, or income taxes. NOI represents the property's cash-generating power before financing — which is why cap rate is useful for comparing properties regardless of how individual buyers might finance them.

Why Lower Cap Rates Exist
Lower cap rates are not inherently bad — they reflect investor confidence. Properties in markets with strong appreciation, low vacancy, high-quality tenants, and stable demand command lower cap rates because buyers are willing to pay more for the income stream. A 4% cap rate in Manhattan means investors believe the income is extremely reliable and the property will appreciate. A 10% cap rate in a rural market suggests higher risk or lower confidence in future appreciation.
Using Cap Rate for Property Valuation
Cap rates allow you to estimate a property's value based on market data: if comparable properties in a neighborhood trade at a 6% cap rate and your property has a $24,000 NOI, the implied value is $24,000 ÷ 0.06 = $400,000. This is how commercial appraisers value income properties — using the income approach with comparable market cap rates.
