. . . exist for an improvement of this magnitude; that to extend the analysis to a different neighborhood, in which larger units are less atypical, might warrant relatively significant downward adjustments if that area is superior--or to justify the absence of a location adjustment, which might be impossible to do, if the "other" neighborhood demographics are dissimilar to the subject, based upon the potential for a neighborhood comprised of larger and, ergo, higher priced homes typically to be superior. Towards that end the "enhanced" GLA might not warrant any adjustment; and the additional, tangible costs of owning the larger unit might actually require downward adjustments to reflect the financial burden of enhanced utilities, taxes, maintenance, etc., relative to smaller units in the same hood.
Others will say hogwash a bigger house inherently is more valuable, but others will ask for proof of "market reaction" rather than "personal opinion" upon which that call can be made.
[It's intersting, at least to me as a perpetual newbee, how virtually all of the threads on the forum eventually dovetail into a relatively singular, straightforward approach to appraising, as tangled a web--proverbial web not intellectual web--as it is...]
