Appraisers must preserve the confidentiality of the subject matter, be objective, not charge excessive fees, and prepare clear, concise, and correct reports. It is unethical for appraisers to accept assignments and appraise items that they have an interest in buying. Do not agree to a fee based on the value of an item, because this may tempt an appraiser to overvalue the item. Fees are usually determined by the type and purpose of the appraisal, the degree of difficulty, and the type of item appraised. Speak to several appraisers, and do not necessarily hire the one charging the lowest fee.
Most good experts charge an hourly fee.
Expect to be charged for travel, research, and writing time. For large jobs, like an inventory of an estate, appraisers make a preliminary visit and, for a fee, give an estimate of the entire cost. Get the appraiser to agree to deduct the preliminary visit fee from the entire fee if ultimately hired. Insist on a written contract or letter of agreement describing the arrangement. You should receive a full description of each piece, including its age, characteristics, physical condition, and, if significant, national origin.
