Some unqualified sales may consist of foreclosures, court settlements, transfers of deed between relatives, in which full market value is not arrived at in the transaction.

Quality - A subjective classification of a structure by an appraiser, intended to describe materials used, workmanship, architectural attractiveness, functional design, and the like.
