Regulations on Real Estate Appraisal Article 85

While several different legal uses are found on a parcel of land, the value of this land parcel could be derived as the sum of values for individual portions with different legal uses or appraised based on the primary use, after taking consideration of the highest and best use, the relationship among those different legal uses, and the difficulty for partitioning this land parcel.
