11. Subject to section 13, the price of a sale shall be adjusted where that sale is entered on the basic list, has not been subtracted under Subdivision 2 and, for a reason mentioned in section 12, does not reasonably correspond to the actual value of the unit of assessment according to market conditions as of 1 July of the second fiscal period preceding the fiscal period for which the median proportion is being determined.
The adjusted price shall reasonably correspond to that value.
