Some appraisals take longer than others, depending on the complexity of your property. The time on site will be enough time for the Appraiser to measure the outside walls, walk through the property, gather information on updates / potential issues, and take photographs. Once that portion of the Appraisal is done the Appraiser will leave the property and continue working on generating a property valuation.
This information will then be matched with their research on comparable property sales, market research, neighborhood trends, any projected repair costs, etc. Most of the time required to generate a professional real estate appraisal is done off site. We are aware deadlines may be present and will do everything within our power to meet those deadlines for you.
