The applicant shall be entitled to just compensation for actual
loss found to be caused by such temporary reservation and deprivation
of use. In such instances, unless a lesser amount has previously been
mutually agreed upon, just compensation shall be deemed to be fair
market value of an option to purchase the land reserved for the period
of reservation, provided that determination of such fair market value
shall include but not be limited to consideration of real property
taxes apportioned to the land reserved and prorated for the period
of reservation. The applicant shall be compensated for the reasonable
increased cost of legal, engineering or other professional services
incurred in connection with obtaining subdivision or site plan approval
caused by the reservation.
