An appraiser finds a public records file that omits a recent addition to the subject. What does this illustrate?

Correct Answer

A) That public records may lag physical changes

Why this is correct: The governing concept is that public records, such as assessor databases, are not real-time updates. They often lag behind physical changes to a property due to administrative processing delays. Finding a discrepancy does not automatically imply the addition was unpermitted; it simply highlights the need for independent verification. Why the other choices are wrong: "That the addition must have been unpermitted" is incorrect because a lag does not prove lack of permits; further research is needed. "That public records may not be used as a source" is incorrect because they can be used but must be verified. "That the assessor is required to correct the file" is incorrect because while assessors update records, there is no immediate requirement, and the appraiser's duty is to verify independently. Exam tip: Treat public records as a starting point, not definitive; always verify physical characteristics through inspection or other means.

Answer Options

That public records may lag physical changes

That the addition must have been unpermitted

That public records may not be used as a source

That the assessor is required to correct the file

Why This Is the Correct Answer

The gap between the record and the physical reality is a timing problem in the data source, and recognizing that is the concept being tested. Public records depend on reporting, inspection, and clerical updating, each of which introduces delay, so an omission is evidence about the record's currency rather than about the property's legality. Reading the discrepancy this way keeps the appraiser in the posture of verifying rather than concluding. Choice A states that limitation without overreaching in either direction.

Why the Other Options Are Wrong

Option B: That the addition must have been unpermitted

An unpermitted addition would explain the omission, but so would a permit issued after the last reassessment, a data entry backlog, or a jurisdiction that does not track that improvement type. Jumping from a records gap to an unpermitted conclusion is an unsupported inference, and it matters because unpermitted work carries real valuation consequences that must rest on permit research, not on a guess. The right move is to pull the permit history and find out.

Option C: That public records may not be used as a source

Public records remain a legitimate and often indispensable data source, used for legal description, ownership history, sale prices, lot dimensions, and assessment data. Nothing prohibits their use; the obligation is to take reasonable steps to verify data used in the analysis. Discarding an entire source because one field was stale would leave the appraiser with less information and no better verification.

Option D: That the assessor is required to correct the file

Assessing offices update records on their own statutory cycle and owe their duty to the taxing jurisdiction, not to an appraiser working a private assignment. Even a prompt correction would not relieve the appraiser of verifying the improvement independently. Treating the assessor as a quality control department for your file misplaces where the verification responsibility sits.

Trust the Tape Measure, Not the Tax Roll

The tax roll tells you what the county knew as of its last cycle. The tape measure tells you what is standing today. When they disagree, the roll is behind, and behind is not the same as illegal.

How to use: When a stem shows a records-versus-reality mismatch, pick the option that names the limitation of the source. Reject options that convict the owner, ban the source, or hand the problem to a government office.

Exam Tip

The moderate, verification-minded option usually wins on data source questions. Watch for absolute words like must, never, and required, which mark the overreaching distractors.

Common Mistakes to Avoid

-Concluding an addition is unpermitted because the assessor file does not show it
-Reporting assessor square footage that the field measurement contradicts
-Assuming verification is complete because a second secondary source repeats the first

Concept Deep Dive

Analysis

Assessor and recorder files are secondary data compiled for taxation and title purposes on an administrative cycle, not maintained as a real-time inventory of what is physically standing on a parcel. Permits get issued, work gets built, and the field appraisal or data entry that updates the record can trail the construction by a reassessment cycle or longer, and in some jurisdictions minor additions never get picked up at all. A mismatch between the record and what the appraiser observes is therefore ordinary and expected, and its meaning is that the record needs corroboration rather than that the improvement is illegitimate. The professional response is to treat the discrepancy as a research lead, checking permit history, prior listings, aerial imagery dates, and the owner's account, both to confirm the improvement exists and to establish whether it was built legally, which is a separate question with its own valuation consequences.

Background Knowledge

You need to know what public records contain and how they are maintained, including reassessment cycles and permit reporting, and to distinguish primary data the appraiser observes or confirms from secondary data compiled by others. You also need the general obligation to verify data relied upon in an assignment, and to recognize that legal conformity of an addition is a separate research question from its physical existence.

Real-World Application

An appraiser measures 2,340 square feet against an assessor record of 1,920, pulls a building department permit issued 14 months earlier and finaled 9 months earlier, confirms the sunroom addition is legal and permitted, and reports the measured area while noting the record discrepancy and how it was resolved.
