Key facts: Tennessee requires professional property appraisals for estates exceeding $50,000 in value; a mandatory 30-day waiting period applies following issuance of letters testamentary; appraisals must be filed with the probate court within 60 days of personal representative appointment; valuations must reflect fair market value as of the date of decedent's death; and failure to comply with appraisal requirements can result in personal liability for the executor and potential probate court intervention.
