An appraiser measuring the area of a house would use which measurement?

• A. Exterior dimensions
• B. Interior square footage
• C. Net living area
• D. Gross living area

Answer: (A)

The main idea is that measuring a house's area starts with the exterior dimensions because they capture the full footprint of the structure as it sits on the lot. This exterior-based measurement provides a stable, consistent basis for comparing properties, since interior measurements can vary with wall thickness, interior partitions, and remodeling. Once the footprint is established, appraisers can classify or refine space into living-area categories (like gross living area) if needed, which are derived from the interior finished spaces above grade, but the foundational size comes from the exterior dimensions. Interior square footage and classifications like net living area or gross living area rely on how the space is used or finished inside, not on the initial footprint measurement.
