The Appraisal Report consists of the premise of value, approaches to value, appraisal results, appraisal certification, and more. The calculation worksheet and Blue Book page is attached to and made part of each report. If it is an onsite verification, the supporting documents from the onsite representative are attached. All reports that HeliValue$ creates are USPAP compliant. The report length will vary depending on the number of helicopters being appraised.
