Two houses in the same market each have a carefully developed cost approach. One is newly completed and is a proper improvement for its site; the other is 45 years old with several components near the end of their lives. Why is the cost indication usually the more reliable for the new house?
Correct Answer
D) Depreciation, the most subjective cost input, is minimal for the new house.
For a new, proper improvement, depreciation is minimal, which reduces the significance of the most subjective part of the cost estimate and allows greater weight on the cost approach. The belief that cost new is an upper limit of value usually reflects conservatism or error, buyers do not price houses from builders' records, and site value does not depend on the age of the improvements.
Why This Is the Correct Answer
Option D is correct because depreciation is the most subjective part of a cost estimate, and in new or almost new properties it is minimal. With that uncertain component small, the cost indication for the new house rests mostly on cost new and site value, so the appraiser can give it greater weight.
Why the Other Options Are Wrong
Option A: Cost new sets the upper limit of value for a newly built house.
Option A says cost new sets the upper limit of value for a new house. Treating cost before depreciation plus land as a ceiling on value is generally the result of conservatism, error or misapplication; nothing inherent in the cost approach makes it the top of value.
Option B: Buyers of new houses base their offers on the builder's cost records.
Option B claims buyers base their offers on the builder's cost records. Buyers respond to market alternatives and prices, not to a builder's internal costs, so this does not explain the cost approach's reliability.
Option C: Site value is easier to support for a new lot than for an older lot.
Option C credits easier site valuation for a new lot. Site value is estimated the same way for land under a new or an old house, so the age of the improvements does not make the site estimate more reliable.
New house, little guesswork
Depreciation is where the guesswork lives in the cost approach. A new, proper improvement has little depreciation, so it has little guesswork.
How to use: Use this when deciding how much weight the cost approach deserves for new versus older improvements.
Exam Tip
Look for the words new and proper improvement together; an overimproved or misplaced new building may still carry significant depreciation from obsolescence.
Common Mistakes to Avoid
- -Treating cost new plus land as a ceiling on value
- -Giving the cost approach heavy weight on old buildings with poorly supported depreciation
- -Assuming any new building is a proper improvement for its site
Concept Deep Dive
Analysis
The question asks the candidate to explain, not just state, why the cost approach gains weight for new construction. The comparison between a new house and a 45-year-old house points to depreciation, which is small and easy to support for the new house but large and judgment-heavy for the old one. Each distractor offers a plausible-sounding but unsupported reason.
Background Knowledge
The cost approach adds site value to the cost new of the improvements and subtracts accrued depreciation. When a property is a new and proper improvement, replacement and reproduction cost tend to coincide and depreciation is small, so the indication is more dependable than for an older building with heavy, hard-to-measure depreciation.
Real-World Application
An appraiser values a just-completed house in a subdivision of similar new homes and a 45-year-old ranch across town. She gives the cost approach meaningful weight on the new house but little on the older one, explaining that accrued depreciation on the older house cannot be reliably measured.
More Reconciliation Questions
In a cost approach for an improved property, an appraiser estimates site value by sales comparison, allocation and extraction, then settles on one site-value figure before final reconciliation. How is this step best described?
An extraordinary assumption was reasonably supported, properly used and disclosed in an appraisal report. Later, the assumed information is found to be false. Which conclusion is best supported?
An otherwise applicable valuation approach cannot be developed reliably from the available data. The remaining scope can produce credible assignment results. What should the appraiser do?
May an appraiser use a hypothetical condition in any assignment?
An appraisal has a current effective date and permits an extraordinary assumption if its requirements are met. Which situation involves uncertain information rather than a fact known to be contrary to reality on that date?
Why must a report identify any real property interest that is being excluded from the value opinion?
Which review best helps explain divergent cost, sales-comparison and income indications?
Two value indications are $340,000 and $392,000. What is the difference as a percentage of the lower indication, rounded to one decimal place?
An unauthorized third party requests a lender-client’s report. No due-process or other permitted disclosure exception applies. How should the appraiser respond?
An appraiser proposes to assume there are no hidden defects. Which fact would characterize that assumption as extraordinary under the USPAP 2024 definition, rather than justify dismissing it as routine boilerplate?
