Net Operating Income (NOI) definition

Net operating income is the income a property produces after subtracting operating expenses such as taxes, insurance, maintenance, and management. It does not subtract mortgage payments, because debt service is a financing cost, not an operating cost.

Net operating income drives the income approach: value equals net operating income divided by the capitalization rate.
