An appraiser receives photographs of a comparable taken by someone else. How should they be treated?

Correct Answer

C) As data whose source and date should be identified

Why this is correct: USPAP requires disclosing the source and date of all data used, including third-party photos, to maintain transparency and credibility. Why the other choices are wrong: 'As proof the appraiser inspected that comparable' would misrepresent the appraiser's personal observation. 'As a substitute for describing the property in text' is insufficient; descriptions are still needed. 'As inadmissible, since the appraiser did not take them' is false; they can be used with proper attribution. Exam tip: Always cite sources for any data you didn't personally generate or verify firsthand.

Answer Options
A
As proof the appraiser inspected that comparable
B
As a substitute for describing the property in text
C
As data whose source and date should be identified
D
As inadmissible, since the appraiser did not take them

Why This Is the Correct Answer

Treating them as data whose source and date should be identified is the handling that keeps the report accurate and lets the reader assess the evidence. Attribution prevents the reader from inferring personal observation the appraiser did not perform, and the date lets the reader judge whether the image reflects conditions relevant to the effective date. Identifying the source also supports the verification step, since the credibility of a photograph depends partly on who supplied it and whether the appraiser corroborated what it shows against other data. It is worth noting that USPAP does not impose a single blanket rule to cite the source and date of every datum; the requirement flows from the prohibition on misleading reports, from the obligation to describe the scope of work accurately, and from the reporting requirement that the report contain sufficient information for intended users.

Why the Other Options Are Wrong

Option A: As proof the appraiser inspected that comparable

Presenting a photograph taken by another person as evidence of the appraiser's own observation misstates the scope of work, which the report is required to describe accurately. The extent of personal observation is a scope decision intended users rely on, and overstating it is the kind of misrepresentation the ETHICS RULE addresses. Candidates pick this because a photograph feels like proof of presence, forgetting that presence is the one thing a borrowed photograph cannot document.

Option B: As a substitute for describing the property in text

A photograph shows condition and appearance at one instant from one angle and cannot carry the descriptive content the analysis needs, such as the comparable's size, layout, or the specific characteristics driving adjustments. Reports use images to supplement written description rather than to replace it, and a reader cannot extract adjustment-relevant facts from a picture. This option confuses illustration with analysis.

Option D: As inadmissible, since the appraiser did not take them

No rule renders third-party data inadmissible, and an appraisal practice limited to personally generated data would be impossible, since sale prices, listings, and records all come from others. What matters is whether the appraiser used the data appropriately, attributed it, and verified what could be verified. The option overcorrects a legitimate transparency concern into a prohibition that does not exist.

Whose Eyes, Which Day

Every borrowed image carries two questions the reader will ask: who took it and when. Answer both in the report and the photograph is evidence. Answer neither and it quietly implies you were standing there.

How to use: When a stem involves data the appraiser did not generate, look for the option that permits its use with attribution. Options treating it as proof of inspection, as a substitute for description, or as inadmissible are each mishandling the same underlying transparency question.

Exam Tip

Scope of work statements are where inspection claims live. Any answer that would make the scope description inaccurate is wrong regardless of how useful the data is.

Common Mistakes to Avoid

  • -Including borrowed images without attribution, so the report implies personal observation
  • -Omitting the photograph's date, leaving the reader unable to relate it to the effective date
  • -Letting images stand in for the written description and verification of a comparable

Concept Deep Dive

Analysis

Third-party photographs are data like any other data, and the question is how an appraiser handles data they did not personally generate. Nothing in USPAP bars using information from others; Standard 1 contemplates collecting, verifying, and analyzing such data as are available, and appraisers routinely rely on multiple listing services, public records, and cooperating parties. What USPAP does police is misrepresentation and transparency: an appraiser must not communicate a report in a misleading manner, and the report must accurately describe the scope of work performed, including the extent to which properties were personally observed. A photograph taken by someone else can therefore support the analysis, but it cannot be presented in a way that implies the appraiser was there, and the report should make clear where it came from and when it was taken so the reader can weigh its currency and reliability. Date matters as much as source, because a photograph predating the effective date may not depict the property as it existed when the opinion applies.

Background Knowledge

You need to know that appraisers routinely rely on data from others and that Standard 1 contemplates collecting, verifying, and analyzing available data rather than personally generating all of it. You should know that the report must describe the scope of work accurately, including the extent to which the subject and comparables were personally observed, and that a report may not be communicated in a misleading manner. You also need to know that a photograph's date bears on its relevance to the effective date, and that attribution supports rather than substitutes for the verification step.

Real-World Application

Appraising a rural comparable that sold eight months ago and is now behind a locked gate, an appraiser obtains exterior photographs from the listing broker who took them during the marketing period. The report includes the images labeled with the broker's name as source and the month they were taken, states in the scope of work that the comparable was viewed from the public road and not personally photographed, and corroborates the improvements shown against the listing description and county records.
