Do appraisers go inside the house during an appraisal?

Yes, when the assignment is a full appraisal, the appraiser inspects both the interior and exterior of the home, noting condition, layout, size, and updates, and photographs the property. Not every assignment includes a visit: a drive-by appraisal relies on an exterior inspection only, and a desktop appraisal is completed from public records and other data without a physical inspection.
