As long as the residential use is a legal one, you can do the appraisal (if you want it.) However, H&BU as vacant will likely turn out to be to improve the property. THEN you have to consider all that commercial stuff to determine the ideal improvement and bounce it off the typical improvement. PITA, but it helps to determine the amount of functional obsolescence associated with using commercial property for residential purposes.
H&BU as improved would likely turn out to be "present use," unless cost of purchase, demolition, and construction would yield a higher return. May be, maybe not. See if X-Boss lady can help you with it, if you want to use it as a study assignment. It is on assignments like this that CG's earn their pay.
