EGI is $410,000 and operating expenses including reserves total $168,000. Net operating income is:

Correct Answer

D) $242,000

Why this is correct: Net Operating Income (NOI) = Effective Gross Income (EGI) - Operating Expenses (including reserves). Calculation: $410,000 - $168,000 = $242,000. Why the other choices are wrong: '$205,000, using a fifty percent expense ratio' incorrectly applies a generic ratio instead of the given numbers. '$578,000 combining the two figures' mistakenly adds instead of subtracts. '$168,000, the expense total itself' is just the expense figure, not NOI. Exam tip: NOI = EGI - Total Operating Expenses. It's a simple subtraction; the challenge is ensuring all proper expenses are included.

Answer Options

$205,000, using a fifty percent expense ratio

$578,000 combining the two figures

$168,000, the expense total itself

$242,000

Why This Is the Correct Answer

$242,000 is EGI of $410,000 minus operating expenses of $168,000, which is the definition of net operating income applied directly. The stem specifies that reserves are already inside the $168,000, so no further deduction is needed and none should be added back. The resulting expense ratio of about 41 percent is plausible for many property types, which is a useful sanity check but is not what produces the answer. Once NOI is in hand it becomes the numerator in direct capitalization, dividing by the overall rate to indicate value.

Why the Other Options Are Wrong

Option A: $205,000, using a fifty percent expense ratio

$205,000 is exactly half of the $410,000 EGI, produced by assuming a fifty percent expense ratio instead of using the expense figure the stem provides. Rules of thumb like the fifty percent ratio are screening devices, not substitutes for actual operating data, and the problem supplies the actual data. Reaching for a benchmark when real numbers are on the page is the error this option is designed to catch.

Option B: $578,000 combining the two figures

$578,000 adds the two figures rather than subtracting, which would mean expenses increase the income the property produces. NOI can never exceed EGI, so the result fails a basic reasonableness test before any calculation is checked. This is a sign-direction slip rather than a conceptual misunderstanding.

Option C: $168,000, the expense total itself

$168,000 is the operating expense total copied forward as though it were the answer. It is the amount removed from EGI, not what remains after removal. Selecting it means the subtraction was never performed.

Effective Minus Expenses

The letters do the work. E minus E is N: Effective gross income minus Expenses equals Net operating income. If the number you produced is larger than the E you started with, you added when you should have subtracted.

How to use: Locate which line of the statement the stem hands you before calculating. If it says effective gross, vacancy is already removed and only expenses remain to subtract. If it says potential gross, take out vacancy first.

Exam Tip

Check the stem for the words including reserves. That phrase settles the one judgment call in the problem and tells you not to make any further adjustment to the expense figure.

Common Mistakes to Avoid

-Deducting debt service or income taxes and calling the remainder net operating income
-Omitting reserves for replacement when the owner's own statement never showed them
-Substituting a market expense ratio for the actual expense data given in the problem

Concept Deep Dive

Analysis

This item checks whether you can execute one line of the income and expense reconstruction without being pulled off by a plausible shortcut. The statement runs from potential gross income down through vacancy and collection loss to effective gross income, and then subtracts operating expenses to reach net operating income. Because the stem hands you EGI directly, the vacancy step is already behind you and only the subtraction remains: $410,000 less $168,000 equals $242,000. The stem also settles the one substantive judgment call by saying the expense figure includes reserves for replacement, which the appraiser deducts above the NOI line so that the income stream reflects the periodic cost of replacing short-lived components. What is deliberately not deducted is debt service, income taxes, depreciation for tax purposes, or capital improvements, since NOI is a property-level figure independent of how any particular owner financed or is taxed on the asset.

Background Knowledge

You need the income and expense statement in order: potential gross income, less vacancy and collection loss, plus other income, equals effective gross income; less operating expenses equals net operating income. You must know which items are operating expenses, including fixed expenses, variable expenses, and reserves for replacement, and which are excluded, namely debt service, income tax, book depreciation, and capital expenditures. You should also know that NOI feeds direct capitalization as value equals NOI divided by the overall capitalization rate.

Real-World Application

Reconstructing the operating statement for a small apartment building, the appraiser removes the owner's mortgage interest and depreciation from the expense schedule because they are not property-level operating costs, then adds a reserve for roof and appliance replacement that the owner never booked. The reconstructed NOI, not the owner's reported cash flow, is what gets capitalized.
