A 1,850 sq ft dwelling is estimated at $162 per square foot, with a 480 sq ft garage at $58 per square foot and $19,000 of site improvements. Cost new totals:
Correct Answer
D) $346,540
Why this is correct: Total cost new is the sum of all components at their appropriate rates. Calculation: Dwelling: 1,850 sq ft * 162 dollars/sq ft = 299,700 dollars. Garage: 480 sq ft * 58 dollars/sq ft = 27,840 dollars. Site improvements: 19,000 dollars. Sum: 299,700 + 27,840 + 19,000 = 346,540 dollars. Why the other choices are wrong: The choice stating 299,700 for the dwelling alone is incorrect; it omits the garage and site improvements. The choice of 381,300 pricing the garage at the dwelling rate is wrong; it uses the wrong rate (162 dollars) for the garage. The choice of 327,540 excluding the site improvements is false; it includes the garage but incorrectly excludes the 19,000 dollars for site work. Exam tip: In cost estimates, apply component-specific unit rates. Don't inflate value by using the main structure's rate for ancillary items.
Why This Is the Correct Answer
Pricing each component at its own rate gives $299,700 for the dwelling, $27,840 for the garage and $19,000 of site improvements, totalling $346,540.
Why the Other Options Are Wrong
Option A: $299,700 for the dwelling alone
$299,700 is the dwelling alone. It omits both the garage and the site improvements.
Option B: $381,300 pricing the garage at the dwelling rate
Pricing the garage at the dwelling's rate overstates it substantially, since unfinished garage space costs far less per square foot.
Option C: $327,540 excluding the site improvements
$327,540 is the dwelling plus the garage but leaves out the $19,000 of site improvements.
Each Component, Its Own Rate
Each Component, Its Own Rate, then add the site improvements. Garage space is not living space.
How to use: List the components before multiplying. The errors in these questions are always an omitted or mispriced component.
Exam Tip
Site improvements are part of cost new, not part of land value. Adding them to the land is a common double-count error.
Common Mistakes to Avoid
- -Applying the dwelling rate to garage area
- -Omitting site improvements from cost new
- -Treating cost new as the cost approach conclusion
Concept Deep Dive
Analysis
Cost new in the cost approach is built by pricing each component at its own rate and then adding the site improvements, and the arithmetic here is straightforward once the components are kept separate. The dwelling contributes 1,850 × $162 = $299,700. The garage is priced at its own rate because garage construction costs substantially less per square foot than finished living area — no interior finish, no plumbing, minimal electrical — giving 480 × $58 = $27,840. Site improvements of $19,000 cover driveway, walks, landscaping and similar items that are part of the improvements rather than the raw land. The total is $346,540. Each distractor represents a specific error the exam is testing: stopping at the dwelling, pricing the garage at the dwelling's rate, or omitting the site improvements. In practice this figure is only the starting point, since accrued depreciation is then deducted and land value added to reach the cost approach indication.
Background Knowledge
Cost new is developed by pricing each building component at its appropriate unit rate and adding site improvements. Accrued depreciation is then deducted and land value added to produce the cost approach indication.
Real-World Application
An appraiser prices a 1,850 square foot dwelling and its garage at separate unit rates, adds site improvements, and carries $346,540 forward as cost new before depreciation.
More cost-approach Questions
In a cost approach for a proposed building, the appropriate cost basis is generally:
A 45-year-old office building has undergone multiple high-quality renovations, including HVAC replacement, seismic retrofitting, and full interior modernization. Its functional layout remains competitive with new construction, and it occupies a stable, well-located corridor. The appraiser estimates its total economic life at 70 years. Which estimate of effective age is most supportable under USPAP and recognized cost approach methodology?
A warehouse cost $210,000 to build when the cost index stood at 105. The index is now 210. Its indicated current cost is:
An appraiser is estimating accrued depreciation for a commercial office building using the age-life method. The building was constructed in 1992 and has a total economic life of 60 years. As of the appraisal date in 2024, the appraiser determines the property’s effective age is 36 years due to consistent maintenance, modernized systems, and favorable market perception. What is the percent of accrued depreciation indicated by the age-life method?
Which event would RAISE a building's effective age relative to last year's estimate?
Two identical houses were built the same year; one has been meticulously maintained, the other neglected. Their age-life analyses differ because:
Which statement is MOST consistent with USPAP Standards Rule 6 regarding the identification and treatment of external obsolescence in the cost approach?
A 40-year-old industrial warehouse has undergone no major renovations and suffers from outdated electrical systems, inefficient insulation, and obsolescent loading dock design. Market evidence indicates similar properties typically exhibit functional obsolescence reducing utility by 15% and external obsolescence reducing value by 10%. If the appraiser uses the age-life method with a total economic life of 50 years, how should effective age be adjusted to reflect these conditions?
In developing an age-life depreciation estimate, an appraiser assigns an effective age of 16 years and a total economic life of 40 years. Later, the appraiser discovers that comparable properties in the same submarket have recently sold with effective ages averaging 12 years and total economic lives averaging 45 years — and those sales exhibited superior energy efficiency and adaptive reuse features. What is the appraiser’s USPAP-compliant obligation regarding the original effective age estimate?
The age-life method expresses depreciation as:
