An appraisal that allows for an exterior inspection only is suitable for which type of property?

An appraisal that requires only an exterior inspection is particularly suitable for a single-family unit. This method, often referred to as a "drive-by appraisal," is commonly used when the property's overall condition can be adequately assessed from the outside without the necessity of a detailed interior inspection.

Single-family homes often have standardized features that can be evaluated from the exterior, allowing appraisers to make assumptions about the property's condition, such as the state of the roof, siding, and overall curb appeal. This type of appraisal can save time and costs when the property type and current market conditions allow for such an approach.

For other property types, such as multi-unit properties, commercial properties, or vacant land, a more in-depth appraisal is typically necessary. Multi-unit and commercial properties often require a thorough understanding of construction quality, tenant evaluations, and operational income, while vacant land requires an assessment of zoning regulations and potential use. Thus, the single-family unit stands out as the most suitable for an exterior-only appraisal.
