Before And After Method
An appraisal method used in both condemnation and modernization. In condemnation the method is used in a partial taking. The value of the total land owned by A, for example, is $1.00 per sq. ft. After a partial taking, the remaining land of A is worth $.75 per sq. ft. A should receive $1.00 per sq. ft. for the property taken plus $.25 per sq. ft. for the remaining parcel. In the event the remaining property is worth $1.25 after the taking (increased value), the payment to A could be less than the value of the property taken. In modernization, an appraiser may take the value of property before and after remodeling to determine if the value increased more than modernization costs.
