Effective gross income is $118,800 and operating expenses total $43,800. Net operating income is:
Correct Answer
B) $75,000
Why this is correct: Net Operating Income (NOI) equals Effective Gross Income minus Operating Expenses. Here, $118,800 - $43,800 = $75,000. Operating expenses typically include all normal expenses like management, reserves, taxes, and insurance. Why the other choices are wrong: "$62,000 after also deducting the reserves" incorrectly deducts reserves twice if they are already in the $43,800. "$118,800 less debt service, whatever that is" confuses NOI with cash flow (debt service is a financing cost, not an operating expense). "$81,000 before management fees" adds an arbitrary amount. Exam tip: NOI = EGI - Operating Expenses. Debt service is not an operating expense.
Why This Is the Correct Answer
Subtracting operating expenses of $43,800 from effective gross income of $118,800 leaves $75,000, which is net operating income by definition. The stem supplies the total operating expense figure, so no further deduction of any component is appropriate. The result is a before-financing, before-income-tax figure ready to be capitalized or discounted. Choice B is the clean application of the formula.
Why the Other Options Are Wrong
Option A: $62,000 after also deducting the reserves
This deducts reserves a second time after they are already inside the $43,800 total, which understates net operating income by the amount of the reserve. Reserves for replacement are an operating expense in appraisal practice, so they belong in the expense total once and only once. Whenever a stem gives a total, resist the urge to peel off a component you were taught to include.
Option C: $118,800 less debt service, whatever that is
Debt service is a financing cost, not an operating expense, and subtracting it produces pre-tax cash flow to equity rather than net operating income. Capitalizing a figure net of one buyer's loan payments would make value depend on that buyer's financing rather than on the property. The stem's own vagueness about the amount is a hint that the item does not belong in the calculation at all.
Option D: $81,000 before management fees
Management is an operating expense that belongs in the deduction whether or not the owner hires a third party, since a buyer would price the property assuming market management costs. A figure described as before management fees is therefore an incomplete deduction, and the number itself does not follow from either input in the stem. Leaving management out overstates net operating income and, capitalized, overstates value.
Above the Line, Below the Line
Everything the property needs to operate sits above the line and gets deducted. Everything the owner arranged, meaning the loan and the tax return, sits below the line and never touches net operating income.
How to use: Sort each item in the options into property costs or owner costs before doing arithmetic. Any option that pulls a below-the-line item into the subtraction is wrong regardless of the number attached to it.
Exam Tip
When a stem hands you a total operating expense figure, use it as given. Distractors are usually built by deducting a component again or by adding a financing item.
Common Mistakes to Avoid
- -Deducting debt service and calling the result net operating income
- -Omitting a management expense because the owner manages the property personally
- -Double counting reserves already included in a stated expense total
Concept Deep Dive
Analysis
The reconstructed operating statement moves in a fixed order: potential gross income, less vacancy and collection loss and plus other income, gives effective gross income; effective gross income less operating expenses gives net operating income. Operating expenses in appraisal practice cover fixed expenses such as real estate taxes and insurance, variable expenses such as utilities, maintenance, and management, and reserves for replacement of short-lived components, and management is included even when the owner self-manages because the market would require it. Three items are deliberately excluded: debt service, income taxes, and capital expenditures beyond the reserve, because net operating income is meant to describe what the property produces independent of how any particular owner financed or was taxed on it. That independence is what makes NOI comparable across properties and usable with a capitalization rate extracted from other sales, and it is why every distractor in a question like this involves smuggling a financing or double-counted item into the calculation.
Background Knowledge
You need the structure of the reconstructed operating statement from potential gross income through effective gross income to net operating income, and the classification of fixed expenses, variable expenses, and reserves for replacement. You also need to know which items are excluded from operating expenses, namely debt service, income taxes, depreciation as a tax concept, and capital improvements, and why that exclusion keeps net operating income independent of ownership and financing.
Real-World Application
An appraiser reconstructing a small apartment building's statement adds a market management fee the self-managing owner never paid, includes a per-unit annual reserve for roof and appliances, removes the owner's mortgage interest and depreciation from the tax-based records supplied, and arrives at a net operating income a buyer would recognize.
