What is the problem with bias in appraisal practice?

• A. It is irrelevant
• B. It precludes an appraiser's objectivity
• C. It improves accuracy
• D. It ensures fairness

Answer: (B)

Bias in appraisal practice compromises objectivity. An appraisal should rest on verifiable data, sound methodology, and a neutral analysis of market conditions. When bias enters—whether from personal opinions about neighborhoods, demographics, or property features—the appraiser’s judgment becomes tainted, leading to valuations that may systematically favor or disfavor certain properties. This undermines credibility, potentially breaches professional standards, and raises fair housing concerns. That’s why bias is described as precluding objectivity. The other statements don’t fit: bias isn’t irrelevant, it doesn’t improve accuracy, and it certainly doesn’t guarantee fairness; in fact, it undermines both accuracy and fairness by producing distorted results.
