Market Value

The most probable price which a property would bring in a competitive and open market under all the conditions requisite to a fair sale, the buyer and seller each acting prudently and knowledgeably, and assuming the price is not affected by undue stimulus. Implicit in this definition is the consummation of a sale as of a specified date and the passing of title from seller to buyer under conditions whereby: 1) buyer and seller are typically motivated, 2) both parties are well informed or well advised, and acting in what they consider their best interests, 3) a reasonable time is allowed for exposure in the open market, 4) payment is made in terms of cash in U.
