Imo, an investor might order it but I think in reality it is rarely ordered as an appraisal. Most investors do their own valuation for themselves when they look to purchase - they are not idiots and can run the numbers and are up on RE trends - an investor might look to monetize a residential property for Air bnb , which is a value-in-use, and thus pay more than, or compete with, owner occupant buyers for the same property.
Value in use is an important concept for appraisers to know about because it can impact prices or buyer appeal, and it can also lead to a sleazy or not educated client asking for a value-in-use appraisal but they call it market value - and some appraisers fall into that trap themselves -I can't; believe that some here keep post advice to value a residential Air bnb condo or house as if it is a hotel or commercial enterprise... or should they value it on the subject short term rental rate instead of annual market leases?????? / DOH
