Answer: Extraordinary assumption
Explanation: Appraisal could be defined as the estimation or evaluation of an object, property or structure in other to determine either the worth, condition or nature of such property or object.
An Extraordinary assumption during appraisal means a presumption that certain unknown information exists or is a fact. It assumes a condition which is unknown to be true and as such if the information is found to be false may alter the result or conclusion of the appraisal.
