I thought the long-running argument on this thread was in regards to the appropriateness of using a method identified with one approach when analyzing value in another approach?
I brought up several examples where I thought it would be useful:
A. When the market reacts to cost, make the adjustment based on cost in the SCA.
B. When the market reacts to income differences, make the adjustment based on the income difference in the SCA.
I can understand "extracting" an adjustment in the SCA; I can extract an adjustment and not know why the market reacts that way. That happens. The example I used was "appeal"; what may be in favor today can be out of favor tomorrow. Other than matching "like for like" in design, I can't think of a sound way to drill any deeper as to why the market reacts as it does between two styles of design that have similar functional utility.
But in those cases where I can drill deeper, I would want to do so.
If I can correlate income or cost with market reaction to a component of value, then I'm going to use that correlation to consider my market adjustment. And I'm going to cite that correlation as support (basis) for making that adjustment. Wouldn't that give the appraiser (and the user) a higher confidence level about the adjustment being made?
I said before that I think this analysis is extremely useful in justifying when an adjustment is not warranted.
Again, back to a fourplex: Our subject's location appears superior to Comparable A. However, we can determine that superior locations command higher rents. We compare our subject's market rent to that of Comparable A and find no rental difference. Is a location adjustment warranted?
Without analyzing the income, one might make a qualitative argument that a location adjustment is warranted; but
in fact the quality of the location that is perceived by the appraiser
is not recognized in the market as a value premium.
With analyzing the income, one can make a quantitative argument that that there is no location adjustment warranted. And the decision is supported by market evidence that no premium is awarded.
It doesn't take a giant leap to see that if such an analysis is useful in
disproving adjustments, it can also be useful in
proving adjustments.
My valuation toolbox has a number of different tools. I don't have it partitioned as
SCA,
CA and
IA where using one precludes the use of the others. They are all grouped as
Value Analysis tools and I use the one(s) that best analyze the specific valuation problem.
Nothing misleading, being lazy or fraudulent about it. Not a short cut.
