What risk arises when an appraiser uses only one data source for an entire market study?
Correct Answer
B) Transactions outside that source are invisible
Why this is correct: Relying on one source (e.g., MLS) risks missing transactions not captured by that source, such as private sales or auctions, leading to an incomplete market picture. Why the other choices are wrong: 'The study will take longer than using several' is not a primary risk; efficiency isn't the issue. 'Single-source studies are barred under Standard 1' is false; USPAP doesn't bar them but requires credible data. 'The source will charge a higher subscription fee' is a practical concern but not the core appraisal risk. Exam tip: Use multiple sources to ensure data completeness and credibility.
