Capitalization Rate (Cap Rate) in Commercial Real Estate: Complete Guide

What It Means

The capitalization rate is the most widely used valuation metric in commercial real estate, expressing the relationship between a property's net operating income and its market value. A 6% cap rate means the property generates 6 cents of NOI for every dollar of value. Cap rates serve as both a valuation tool and a risk metric — higher cap rates indicate higher perceived risk and/or lower growth expectations.

How It's Calculated

The cap rate is a single number but embeds multiple assumptions: the expected return on investment, risk premium for the specific property and market, growth expectations for income and value, and the opportunity cost of capital. Market cap rates vary significantly by property type, location, tenant quality, and lease structure.

Common Mistakes

Applying cap rates to unstabilized NOI; using in-place NOI when it differs significantly from market; comparing cap rates across different property types without adjustment; ignoring the difference between going-in and terminal cap rates; treating cap rate as a return metric (it approximates yield only under specific conditions).

Connection to Lease Abstraction and Financial Spreading

Cap rate connects directly to NOI (accurate NOI requires precise lease abstraction and financial spreading) and property value. The spread between a property's cap rate and prevailing interest rates (the cap rate spread) indicates relative investment attractiveness. When interest rates rise, cap rates generally follow, reducing property values.
