What is the largest operating expense for any property?

• A. Real estate taxes
• B. Property management fees
• C. Utilities
• D. Insurance

Answer: (A)

This question hinges on which operating cost tends to dominate a property's annual cash outlay: property taxes are typically the largest single expense. They’re assessed by the local government based on the property's value and a local tax rate, so they appear as a fixed, year-to-year obligation that often dwarfs other line items. Even if some costs like utilities or insurance can be sizable, they usually don’t reach the level of the annual tax bill across most property types.

Utilities depend on consumption and occupancy and are often variable or passed through to tenants. Insurance varies but is generally a smaller constant premium compared to the tax bill. Property management fees are usually a percentage of gross revenue or operating income and thus tend to be much smaller than taxes.

So, the largest operating expense is real estate taxes.
