sales cost
The asking or agreed sale price of property expressed per square meter or square foot of floor space.
The sales cost per square unit reflects the asking rate (before sale) and agreed-upon rate (at the time of sale) for any property. It is taken as the average amount of any currency charged per square meter or square foot for floor space within the parcel for which it is measured.
The amount is a rate for a unit of floor area, rather than the total price of the parcel. Currency and the choice of square meters or square feet are part of what the rate expresses.
An asking rate describes the price sought before a sale; an agreed rate describes the price accepted for the transaction. An appraisal alone does not establish either of those transaction prices.
