Frequently Asked Questions
Common questions about NOI calculations and real estate investment analysis
What is Net Operating Income (NOI)?
Net Operating Income (NOI) is a key real estate metric that measures the profitability of an income-producing property. It's calculated by subtracting operating expenses from gross operating income.
How do I calculate NOI for a rental property?
NOI = Gross Operating Income - Operating Expenses. Include all rental income and subtract property management fees, maintenance, taxes, insurance, and utilities.
What expenses should I include in NOI calculation?
Include property management fees, maintenance and repairs, property taxes, insurance, utilities, and other operating expenses. Do not include mortgage payments, capital expenditures, or depreciation.
Why is NOI important for real estate investors?
NOI helps investors evaluate property performance, compare investment opportunities, determine property value using cap rates, and assess cash flow potential before financing costs.
What's the difference between NOI and cash flow?
NOI measures property profitability before debt service, while cash flow accounts for mortgage payments and other financing costs. NOI is a better metric for comparing properties regardless of financing.
How do vacancy rates affect NOI?
Vacancy rates reduce gross income and therefore lower NOI. Use realistic vacancy assumptions (typically 5-10%) when calculating NOI for accurate property analysis.
Can NOI be negative?
Yes, if operating expenses exceed gross income, NOI will be negative. This indicates the property is not profitable and may require expense reductions or rent increases.
How does NOI relate to property valuation?
Property value can be estimated using NOI and capitalization rate: Property Value = NOI / Cap Rate. Higher NOI typically means higher property value at the same cap rate.
