Use the same property boundary and period, accrue or disclose irregular bills consistently, separate recoverable costs and owner-specific items, and document vacancies or utility changes. Compare dollars per unit and percentage of effective income only after definitions match.
Common exclusions
Mortgage principal and interest describe financing; depreciation is a noncash accounting or tax allocation; capital work creates or improves a longer-lived asset; and reserve funding moves cash for future use. Each belongs in the appropriate analysis rather than being hidden in one expense total.

IRS Publication 527: Residential Rental Property
Operating expenses are the recurring costs required to run a rental property: examples can include property taxes, insurance, management, repairs, utilities paid by the owner, landscaping, and administrative costs. The exact reporting definition must be stated.
For NOI analysis, debt service, depreciation, owner income tax, and capital expenditures are usually outside operating expenses. Tax classification can differ from an underwriting or management report, so retain invoices and ask a tax professional about the actual treatment.
Example: repairing a leaking valve may be a current repair, while replacing a building-wide plumbing system may require capital review. The vendor category alone does not determine the classification.
