1. The appraiser should ask the broker or principal about whether the sale is an asset sale or stock sale, as asset sales only transfer certain property rights while stock sales transfer all assets and liabilities. 2. They should inquire about the various entities involved in ownership of the property and whether the sale price incorporates contributions from all entities such as the real estate owner, operating entity, and management company. 3. Important factors that could impact the sale price above or below market value include any distressed conditions of the seller, unique market advantages of the buyer, or the seller being a nonprofit losing money.
