NOI

NOI explained for Westside apartment owners reviewing value, sale planning, buyer underwriting, or diligence.

By Don Favia · Updated July 3, 2026

Direct Answer

Net operating income is income after operating expenses and before debt service, income taxes, depreciation, and capital costs. Buyers use NOI heavily in valuation.

Why It Matters

NOI matters because buyers do not price Westside apartment buildings from headlines alone. They review income, expenses, jurisdiction, condition, debt, documentation, and the risks that could appear during diligence.

Owner Takeaway

Use the concept as a screening lens, not a final answer. The building-specific conclusion should come from the rent roll, actual expenses, property condition, local rules, recent sales, and current buyer demand.
