keep posting, it still won't change. we do not predict values unless we are requested to by the client. as posted elsewhere:
but then you would start in again on the mathematical use of the word predict, which doesn't matter as we are not professional mathematicians, we are appraisers and we follow USPAP...
You provide "an opinion of value" where value is someone's definition of market value, in this case Fannie Mae's definition, which imposes hypothetical conditions and the requirement that your opinion of value is the "most probable" value, which implies that of all the knowledgeable well-advised buyers willing to buy the subject property, assuming there are any, you are providing an opinion of the average or median price they would pay (as a transaction with an "average" seller who typically accepts the highest offer) for the property under the given conditions, something you couldn't possibly know, but have provided a supportable argument that it would be such and such a value for such and such reasons, a prediction that if these buyers actually showed up and bid on the property that your golden value has support for falling somewhere near the middle of these hypothetical transactions , and so you are attempting to PREDICT the outcome of something that hasn't happened, will not, nor ever will happen.
Caveat: Fannie Mae's definition of MV talks about "... the buyer and seller, each acting prudently, ..." as if the appraiser were to focus on the actual buyer and seller, as of the effective date. As of an given effective date, there can be only one seller, the actual seller, who invariably takes the highest offer, assuming he judges the buyer to be sufficiently credit worthy. And the buyer would be the one making that offer. But then we have to make sure the buyer is acting "prudently", meaning that we believe that it is not likely he could get a better deal elsewhere. Then they throw in "the most probable price that a property should bring ...".
Of course if you are appraising for a refinance, there is no buyer - only hypothetical buyers. As of the effective date, you have a seller who isn't interested in selling. For all you know the actual seller has no intention of selling until he can sell it for a much higher value than it is worth at the effective date of appraisal.
So now, who exactly does Fannie Mae mean by "the buyer" and "the seller"? Well, you are required in general to conjure up a hypothetical seller as well. After all, the whole logic behind the sales comparison approach is to find a number of transactions with different buyers and sellers, make adjustments and average, possibly with some weighting. You are effectively defining an "average" or typical buyer and seller for this kind of transaction. And you average the adjusted values and typically give it the most weight for the final value conclusion. And this is typically your support for a transaction between a hypothetical buyer and seller for a hypothetical transaction. The whole goal is to predict what the property would sell for, if there were a typical seller interested in selling the house and some typical buyers interested in buying under the constraints of FNMAs definition of MV.
