This four-day, advanced-level course deals with the valuation of partial acquisitions. The course includes in-depth discussions, exercises and case studies related to the Federal (Before and After) Rule and the State (Summation) Method. The components of compensation (i.e., value of the part taken, damages to the remainder, benefits to the remainder and cost to cure) and methods to quantify each impact are analyzed. Various easement types and valuation methods are examined. Finally, the appraiser, as expert witness, is discussed.
