Do you walk around the house with the appraiser during the appraisal?

You can be present, and sharing information is allowed. The National Association of Realtors states that agents and sellers may communicate with the appraiser and provide details on the home, its improvements and repairs, and the comparables used. Most on-site visits run about one to two hours, and some appraisals, including hybrid and desktop formats, involve no visit at all because data is collected remotely.
