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?
Correct Answer
C) The appraiser must re-evaluate the effective age in light of the new market evidence and document the rationale for any adjustment or retention of the original estimate.
USPAP Ethics Rule and Standards Rule 6-4 require appraisers to develop opinions based on credible evidence and to revise analyses when new, relevant market data becomes available prior to report completion. Advisory Opinion 21 states that effective age must be ‘supported by market data’ — and newly discovered comparable sales constitute material market evidence. The appraiser must therefore reconsider the estimate and document whether the original 16-year effective age remains supportable *in light of* the comparables, or whether adjustment is warranted. Option A violates the Competency and Jurisdictional Exception rules by ignoring contradictory market data. Option B mandates an arbitrary change without analysis — contrary to USPAP’s requirement for reasoned support. Option D mechanically adjusts inputs without addressing the substance of the new evidence.

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?
The age-life method expresses depreciation as:
A warehouse built in 1992 has 24-foot clear ceiling heights — adequate for its original pallet-racking system. Today’s logistics tenants require 36-foot clear heights to accommodate automated storage/retrieval systems (AS/RS). Retrofitting the roof to increase height would cost $1.2 million and disrupt operations for 14 months. Market analysis shows comparable modern warehouses with 36-foot ceilings lease for $0.75/sq ft/month, while this property leases for $0.52/sq ft/month — a $0.23 differential over its 100,000-sq-ft area. Assuming a 10% capitalization rate and ignoring vacancy and expenses, what is the indicated amount of incurable functional obsolescence?
