An appraisal is an opinion of value for a particular market on a particular date. The document describes in detail all the qualitative and quantitative attributes necessary to arrive at the value conclusion. Appraisals are needed for a variety of purposes, the most common being scheduling items for insurance purposes to cover theft, disappearance and damage. For estate purposes, the appraisal is used to determine the fair market evaluation for resale or equitable disbursement of inherited items. In the case of new purchases, an independent appraisal confirms the value of a new purchase with an unbiased and ethical third-party source.
