Anyone could still contract for sale today, with the stipulation that title not pass for 365 days. In doing so, the simple solution is to adjust by the time value of money. No HC.
That is not meet the MV definition that is used on lender appraisals - the assumption in the MV definition is that the title passes as of the (effective date ) which is the specified date of the appraisal.
It could be done the way you describe, but a GSE lender would probably never fund th loan or accept the appraisal done that way.
DEFINITION OF MARKET VALUE: The most probable price which a property should bring in a competitive and open
market under all conditions requisite to a fair sale, the buyer and seller, each acting prudently, 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 each acting in what he or she considers his or her own best interest; (3) a
reasonable time is allowed for exposure in the open market; (4) payment is made in terms of cash in U. S. dollars or in terms
of financial arrangements comparable thereto; and (5) the price represents the normal consideration for the property sold
unaffected by special or creative financing or sales concessions* granted by anyone associated with the sale.
