What is a Cap Rate and Why Does It Matter?
By Benavente Group
A clear explanation of capitalization rates and their critical role in commercial real estate valuation.
The Basics
A capitalization rate — usually shortened to cap rate — is the ratio of a property's annual net operating income to its purchase price or market value. Put in plain terms, it answers the question: if I paid cash for this property, what unlevered return would I earn in the first year of ownership?
A property generating $500,000 of annual net operating income that trades at $10,000,000 has a 5% cap rate. A property with the same income that trades at $7,000,000 has roughly a 7.1% cap rate. Higher cap rates generally signal higher perceived risk, lower cap rates signal lower risk or stronger growth prospects.
Why Cap Rates Matter
Cap rates are the primary language of commercial real estate valuation. In the income approach, an appraiser estimates a property's stabilized net operating income and then divides by a market-derived cap rate to arrive at value. Selecting the right cap rate — supported by current, relevant sales evidence — is often the most consequential judgment in the entire appraisal.
For owners, brokers, and lenders, understanding cap rate dynamics is essential to interpreting valuation opinions and making informed transaction decisions. A valuation that skips the cap rate conversation is a valuation that hasn't done its work.
