THIS IS HYPOTHETICAL IM THINKING AHEAD FOR WHEN IM ASKED TO DO A COMPLEX APPRAISAL. I just took the class and learned nothing that I could apply. I'm doing a complex appraisal for my board exhibit prior to attaining my certification. I am appraising a 3000 sq ft house in a neighborhood of 2000 sq foot houses. No other sold data for a house this large exist in this neighborhood. I am assuming the house suffers from super adequacy and regression. The subject and comparables are similar in all other factors. How do I account for the additional non conforming size in the comparison grid? . Do I take the additional sq footage and value it at a lessor amount? Do I give it full value in and then hit the house for design and appeal? Or functional obsolescence? And if so how much? do I need to find another house in another neighborhood that is nonconforming due to greater size and come up with some sort of discounting factor? And how do I handle this functional obsolescence in the cost approach?
