(3) In the case of any unit of property of which a part of the unit is exempt from taxation, and that part may be identified both as to value and physical description, the real market value of the unit shall not include the value of the exempt part of the unit.
(4) This subsection applies to any unit of property described in subsection (1) or (2) of this section for which the maximum amount of taxes imposed has been determined under this section. If the unit of property is subject to imposition of additional taxes due to disqualification from special assessment or partial exemption, the determination of the maximum amount of additional taxes that may be imposed due to disqualification shall be made on the basis of the real market value of the property for the year to which the additional taxes relate.
