Net Operating Income (NOI)
Definition
Net Operating Income (NOI) is the revenue a property generates after deducting all operating expenses.
Example
A commercial building generates $100,000 in annual rent. Operating expenses, including property taxes, insurance, and maintenance, total $40,000. The NOI is $100,000 - $40,000 = $60,000.
Exam Tip
Remember that NOI is *before* debt service and income taxes. Focus on operating expenses only.
