A question gives you rent, expenses and an asking price. That does not mean you should immediately multiply the rent by a memorized factor. Valuation questions ask you to choose evidence, identify the kind of income supplied and match the method to the property. The arithmetic is often short; deciding which figures belong in it is the real task.
Choose evidence before choosing a formula
The sales comparison approach studies comparable transactions and adjusts for relevant differences. It is especially intuitive when buyers choose among similar properties and reliable comparable sales are available. The cost approach estimates the current cost of improvements, subtracts relevant depreciation and adds land value. The income approach relates income-producing ability to value. No single approach becomes correct for every property merely because the question contains its familiar vocabulary.
If a suburban house has several recent nearby sales of similar homes, the question is likely pointing toward comparison evidence. A specialized new public building with few market comparables may invite cost analysis. A rented investment property with dependable operating data may support income analysis. These are general study patterns, not instructions to ignore the actual market evidence or the appraisal assignment described.
Distinguish an appraiser's opinion of value from a property's asking price or construction invoice. A seller can ask an amount the market does not support. A costly improvement may contribute less value than its cost. An option that declares all three figures identical skips the market question. Read which type of value or evidence the stem is requesting, and do not substitute a tax assessment unless the scenario makes it relevant.
Keep cost and value separate
In a simplified cost approach exercise, begin with land value and the current cost of improvements. Depreciation in appraisal means loss in value from causes such as physical deterioration, functional obsolescence and external obsolescence. It is not necessarily the same amount as accounting depreciation on a tax return. A question can use the same word in two professional settings, so pay attention to the purpose of the calculation.
Physical deterioration concerns wear or damage. Functional obsolescence concerns a problem with utility or design, such as an awkward layout when the market expects a different arrangement. External obsolescence comes from factors outside the property, such as an adverse nearby influence. The categories describe causes, not simply the age of a building. A new building can have a functional problem, and an old building need not suffer every type of depreciation.
Suppose land is valued at $80,000, improvements cost $260,000 to replace and total applicable depreciation is $35,000. The simplified indicated value is $305,000: $260,000 minus $35,000 plus $80,000. Do not depreciate the land merely because you subtract depreciation from improvements. Also do not add the original purchase price of the structure when the question has already supplied a current replacement figure.
Use income only with the right inputs
Direct capitalization is often expressed as value equals net operating income divided by capitalization rate. If annual NOI is $36,000 and the cap rate is eight percent, the calculation is $36,000 divided by 0.08, or $450,000. Using eight instead of 0.08 produces a result one hundred times too small. Unit checks help: annual dollars divided by a rate produce a capital value, not a monthly payment.
NOI is an operating measure. A basic exercise generally starts with income after the stated vacancy allowance and subtracts operating expenses. Debt service and income taxes are not normally operating expenses in this textbook calculation. Capital expenditures also need separate treatment. Use the definitions supplied by the problem; do not subtract a mortgage payment just because it is a real cash outflow for the owner.
A gross rent multiplier uses gross rent, not NOI. Its time period must match the rent figure and the multiplier convention given. A monthly-rent multiplier cannot be applied to annual rent without adjustment. If the stem gives monthly rent of $2,000 and a monthly multiplier of 180, the indicated value is $360,000. Subtracting operating expenses first would turn the stated method into a different calculation.
Work an original appraisal question
Original practice situation: A small rental property has annual effective gross income of $54,000 and annual operating expenses of $18,000. Debt service is $14,000. The question asks for an indicated value using direct capitalization at eight percent. Which amount fits? A: $275,000. B: $450,000. C: $675,000. D: $288,000.
B is correct under the stated simplified method. NOI is $54,000 minus $18,000, or $36,000. Divide that by 0.08 to obtain $450,000. A subtracts debt service before capitalization, producing $22,000 divided by 0.08. C capitalizes effective gross income without subtracting operating expenses. D can result from multiplying a figure by the rate or mixing an unrelated operation. Explaining the wrong operations is more useful than remembering the selected letter.
Now change only the requested output: the question asks for cash flow after the specified debt service. The $14,000 becomes relevant, and the simplified cash flow is $22,000 before any other stated adjustments. The same input can be irrelevant in one method and essential in another. Write the requested output at the top of your calculation, list the allowed inputs below it and label each figure by time period. The valuation concept guide offers another route through the vocabulary; use original numbers when you test whether you can apply it without recalling an answer.
For comparison adjustments, remember which property is being adjusted. In the usual sales comparison exercise, you adjust the comparable to resemble the subject. If the comparable has a feature superior to the subject, that can call for a downward adjustment to the comparable under the stated assumptions. Reversing the reference point reverses the answer.
