(b) Except as provided in subsection (c) of this Section, the assessed valuation of property so platted and subdivided shall be determined each year based on the estimated price the property would bring at a fair voluntary sale for use by the buyer for the same purposes for which the property was used when last assessed prior to its platting.

(c) Upon completion of a habitable structure on any lot of subdivided property, or upon the use of any lot, either alone or in conjunction with any contiguous property, for any business, commercial or residential purpose, or upon the initial sale of any platted lot, including a platted lot which is vacant:

  (i) the provisions of subsection (b) of this Section shall no longer apply in determining the assessed valuation of the lot

the assessed valuation of the remaining property, when next determined, shall be reduced proportionately to reflect the exclusion of the propertythat no longer qualifies for valuation under this Section.
