An appraiser observes that a subject property’s tax assessor record lists a site area of 0.38 acres. The appraiser’s survey shows dimensions of 150 ft × 120 ft. Assuming no measurement error, what is the most likely explanation for the discrepancy?

Correct Answer

C) The tax record reflects lot area before a recent plat correction

Convert survey dimensions to acres: 150 ft × 120 ft = 18,000 sq ft. One acre = 43,560 sq ft → 18,000 ÷ 43,560 ≈ 0.413 acres — not 0.38. 0.38 acres × 43,560 = 16,553 sq ft. Difference is ~1,447 sq ft — too large for rounding. A plat correction (e.g., boundary adjustment, vacated alley, or lot line revision) commonly causes such discrepancies between older tax records and current surveys. USPAP Standards Rule 1-2 requires the appraiser to reconcile such differences and cite the source of the most reliable data — typically a current ALTA/NSPS survey. Option C identifies the most probable cause: tax records lag official plat revisions. Option A is implausible because easements don’t increase lot area; B is incorrect — rods are obsolete and not used in modern tax assessments; D contradicts the stem, which states the survey shows 'dimensions of 150 ft × 120 ft' — a simple rectangle, implying full lot measurement.

Answer Options
A
The tax record includes a recorded easement area not part of the fee simple
B
The tax assessor used rod-based measurement while the surveyor used feet
C
The tax record reflects lot area before a recent plat correction
D
The surveyor measured only the buildable portion, excluding wetlands

Why This Is the Correct Answer
