Which statement about data used in fair housing valuations is most accurate?

• A. Data should be biased to favor the client.
• B. Data quality is optional.
• C. Data should be accurate, but documentation is unnecessary.
• D. Data should be accurate, complete, representative, and sources well-documented.

Answer: (D)

In fair housing valuations, you must rely on data you can trust and defend. Data should be accurate so it truly reflects current conditions, not estimates or guesses that could mislead the analysis. It should be complete so you’re not omitting relevant market factors or neighborhoods, which helps prevent biased conclusions. It needs to be representative so the sample reflects the actual market area and populations involved, avoiding over- or under-representation that could distort results. And all sources should be well-documented, with clear provenance, methods, time frames, and limitations, so the process is transparent and can be audited or challenged if needed.

This combination supports fair, non-discriminatory valuations and makes it easier to defend your methodology under fair housing standards. The other options propose bias, optional data quality, or lack of documentation, all of which undermine reliability and compliance.
