 The concept of assumptions is closely related to the concept of scope of work in the identification of the appraisal problem in the appraisal process.The determination of the scope of work appropriate to the needs of the client, the use of the appraisal results, and the expectations of the appraiser's peers frame the extent of the general assumptions and limiting conditions of the appraisal assignment.An appraisal can involve the assumption or determination of a wide range of facts or conditions.
