Why should an appraiser inspect the site rather than rely only on aerial imagery?

Correct Answer

D) Grade, drainage and access are hard to judge remotely

Why this is correct: A physical inspection is necessary to accurately assess site characteristics that significantly impact value and highest and best use. These include topography (slope, grade), drainage conditions, quality of access, soil conditions, and the presence of encroachments or external factors—all of which are difficult or impossible to judge accurately from aerial imagery alone. Why the other choices are wrong: 'Imagery is prohibited as a source of site data' is wrong; it is an acceptable supplemental tool. 'Inspection is required by statute in every state' is wrong; while often required, the rationale is practical, not purely statutory. 'Aerial images cannot show the parcel's boundaries' is wrong; they often can, but boundaries are confirmed by legal description. Exam tip: Always inspect the site. Key value factors like drainage and slope are ground-level observations.
