The appraisal determines the value given to a conservation easement for purposes of determining the amount of the charitable gift. The Internal Revenue Service requires that the value of the conservation easement be determined by a "Qualified Appraiser" who has at least the designation of "general appraiser".
Land trust standards and practices require that the land trust keep "arm's length" from the appraisal, which means, among other things, that we do not recommend specific appraisers.
