An appraiser (from Latin appretiare, "to value"), is currently defined through standards incorporated into law in many countries. In North America and Europe, these standards are fairly similar, at least at a sufficiently high level.

The current definition of "appraiser" according to the Uniform Standards of Professional Appraisal Practice (USPAP: Uniform Standards of Professional Appraisal Practice) is: "One who is expected to perform valuation services competently and in a manner that is independent, impartial and objective." USPAP further comments on this definition: "Such expectation occurs when individuals, either by choice or by requirement placed upon them or upon the service they provide by law, regulation, or agreement with the client or intended users, represent that they comply."

In effect, to be an appraiser in the United States, an individual must be licensed by the State they practice in, to act as an appraiser. The license is based on a background investigation, an understanding of USPAP and compliance of all associated laws and regulations.

The actual valuation service provided by appraisers typically involves development of an opinion of value based on one or more of three common methods for arriving at value:

  1. The Sales Comparison Approach (SCA)
  2. The Cost Approach (CA)
  3. The Income Approach (IA)


In the United States, the most common usage relates to real estate and personal property appraisals, while the term is often used to describe a person specially appointed by a judicial or quasi-judicial authority to put a valuation on property, e.g. on the items of an inventory of the Tangible Property of an Estate (IRS law) of a deceased person or on land taken for public purposes by the right of eminent domain. Appraisers of imported goods and boards of general appraisers have extensive functions in administering the customs laws of the United States. Merchant appraisers are sometimes appointed temporarily under the revenue laws to value where there is no resident appraiser without holding the office of appraiser (U.S. Rev. Stats. § 2609).[1]
