An appraiser is asked to value a single-family residence but has only appraised commercial properties in the past. To achieve competency, the appraiser could:

Option B: Simply apply commercial appraisal techniques to the residential property

Commercial and residential properties have fundamentally different valuation approaches, market characteristics, and buyer motivations, making commercial techniques inappropriate for residential appraisal. This approach would likely result in an unreliable valuation that doesn't reflect residential market realities. Simply applying commercial methods without understanding residential-specific factors violates the Competency Rule and could mislead clients.

Option C: Decline the assignment because competency cannot be achieved after education

This option incorrectly suggests that competency is fixed and cannot be developed, which contradicts the Competency Rule's explicit provision for achieving competency through education and experience. The rule encourages professional growth and skill development rather than limiting appraisers to their existing expertise. Declining all unfamiliar assignment types would unnecessarily restrict professional development and career advancement.

Option D: Complete the assignment and disclose the lack of experience in the report

While disclosure of experience limitations might seem transparent, completing an assignment without achieving competency violates professional standards regardless of disclosure. The Competency Rule requires actual competency, not just acknowledgment of its absence. Disclosure alone doesn't protect clients from potentially unreliable valuations or absolve the appraiser of professional responsibility.
