IRS lists parking, laundry, and pet fees as taxable rental income (IRS Pub. 527, 2022).
Average U.S. apartment parking fee runs $50–$150 per space per month (National Apartment Association, 2023).
Appraisers start the income approach with GOI before subtracting vacancies (Appraisal Institute, 2020).

FAQ
What is gross operating income?
Gross operating income is the total cash received from rents and service fees before any expense deductions (Appraisal Institute, 2020).
How does GOI differ from effective gross income?
Effective gross income subtracts vacancy and credit loss from GOI, producing a more conservative revenue figure (Fannie Mae Guide, 2022).
Why should investors track GOI regularly?
Tracking GOI shows whether revenue strategies work and flags unexpected dips early, improving portfolio returns (Berkadia Research, 2023).
Can GOI ever be negative?
No—GOI only sums positive inflows. Negative cash flow appears after expenses, not at the gross stage (IRS Pub. 527, 2022).
What counts as “other income”?
Typical sources include parking, storage, vending, pet rent, and application fees—all taxable under U.S. law (IRS Pub. 527, 2022).
How often should you recalculate GOI?
Update monthly for residential assets and quarterly for commercial ones to capture lease turnovers and seasonality (CBRE Market Outlook Report 2023).
Does raising rent always increase GOI?
Only if higher prices do not trigger vacancies; lost tenants reduce rent collected and may lower GOI (Zillow Rental Trends 2023).
How does GOI influence property valuation?
Income-capitalization models divide stabilized GOI (after vacancy adjustments) by a market cap rate to estimate value (Appraisal Institute, 2020).
