Depending on the size and complexity of the property to be appraised, it might take less than an hour to several hours to inspect the property. Some clients perceive this as the entire process but the truth is that it is just the beginning. Appraisers research public ownership and zoning records, investigate demographic and lifestyle information, and compile comparable sales, replacement costs, and rentals. They then analyze this information as it relates to the value of the property. Finally, they write a report on their findings. The inspection is just the beginning of an appraisal process that may take several days or even weeks.
