A cost-approach subject uses older framing and crawlspace details than new competing homes. No engineering defect, market value loss or cure feasibility has been established. How should the appraiser address those differences?
Correct Answer
A) Study utility, condition and market reaction, avoiding double counting
Older framing dimensions or methods do not alone prove unsafe construction, incurable functional loss or a depreciation percentage. Verify actual condition and utility, consider qualified information and market reaction, and distinguish replacement from reproduction cost. Avoid counting the same deficiency in both cost basis and depreciation.
Why This Is the Correct Answer
Option A is correct because the appraiser should study utility, condition and market reaction before deciding whether the differences cause any loss. Older framing and crawlspace details do not alone establish unsafe construction or functional obsolescence. If replacement cost is used, some functional differences may already be reflected in the cost basis, so the appraiser must avoid counting the same deficiency again in depreciation.
Why the Other Options Are Wrong
Option B: Ignore the differences, because age captures the loss
Option B, ignoring the differences because age captures the loss, skips required analysis. Age-based physical depreciation does not necessarily reflect functional differences in design or utility, so the appraiser should still consider them.
Option C: Classify older construction details as curable physical wear and deduct their cost
Option C, classifying older construction details as curable physical wear and deducting their cost, mislabels the issue. Older construction methods reflect changes in building techniques rather than wear and tear, and curability depends on whether the cost to cure is less than the resulting benefit, which has not been established.
Option D: Apply a standard incurable functional percentage to the cost
Option D, applying a standard incurable functional percentage to the cost, uses an unsupported figure. No functional loss has been established here, and any functional obsolescence should be measured from evidence rather than a standard rate.
Prove it, then count once
First prove a loss with evidence on utility, condition and market reaction. Then count it once, either in the cost basis or in depreciation, not both.
How to use: Use this two-step check whenever a cost-approach question involves older construction details.
Exam Tip
Answers that assume a loss, apply a standard percentage or ignore the issue entirely are usually weaker than an answer that calls for supported analysis. Watch for double counting between replacement cost and functional obsolescence.
Common Mistakes to Avoid
- -Treating older construction methods as proof of a defect
- -Deducting functional obsolescence when replacement cost already reflects modern methods
- -Calling design differences curable physical deterioration
Concept Deep Dive
Analysis
This question tests careful depreciation analysis in the cost approach when construction details differ from newer competing homes. Older methods do not by themselves prove a defect, a functional loss or a set percentage. The appraiser should study actual utility, condition and market reaction and make sure the same item is not counted twice, for example once in the cost basis and again in depreciation.
Background Knowledge
Functional obsolescence results from changes in consumer tastes and building techniques and is a loss in value caused by the design of the property itself. Reproduction cost replicates the existing design, while replacement cost uses current methods and materials, which can already remove some functional differences. Curable items are those where the cost to correct is less than the economic benefit.
Real-World Application
An appraiser uses the cost approach for a 1950s home with a crawlspace and older framing, while new competing homes use slabs and engineered framing. She confirms the house is sound, checks whether buyers pay less for the older design, and notes that her replacement cost estimate already uses modern methods so she does not deduct the same difference again.
