Correct but Fannie makes it clear that for appraisal and lending guidelines its being treated as Surplus land and "Valued As in Use" which essentially makes it's Highest & Best use it's existing use. This is done so the appraiser does not overinflated the value based on a future use, which may never happen. This is also why they want the parcels valued as a whole and all teh weight is being placed on the SC Approach. In Private or Non-Fannie type transactions the cleint may engage the appraiser to do them seperately or as a package and at that point the appraiser is doing two appraisals and a much more extensive H & B use analyses. There are situations where teh Subject even with a house on it may be worth less than a larger adjacent parcel. This is more common in Los Angeles County where a small older bungalow is sitting on a 7,000 Sq.Ft. Lot and the same owner has another contigues or adjacent 12,000 Sq.Ft Lot. The Subject by itself is worth $600,000 and the separate-vacant- 12,000 Sq.Ft. lot is worth $700,000. Many Asian buyers buy both and then Build a 5,000 square foot custom home next door to the 1935 Bungalow , or they purchase both and Bulldoze the house down and build two Mc Mansions. On those assignments the appraiser is not dealing with a Fannie situation and the client will order both a home and land appraisal and not a Value In Use.
