this could also be handled via a functional adjustment, thus allowing the appraiser to apply a consistent GLA adjustment factor.There is a situation where you could have a GLA adjustment of $100 for one comparable and $175 for another - that would be in a tiered market. Your 3000 square house competes in a tier of similar sized homes - say 2500 - 3500. But if a lack of data forces the use of a 4900 GLA house. This 4900 GLA is in a different tier of overall prices that "gap-up" well above the the $100 per adjustment you supported in the subject tier. The "gap-up" doesnt support the $100 adjustment - it is $100 plus a premium for being in a different tier. I've seen appraisals with the same $100 GLA adjustment to the 4900 sqft house that ends up adjusting high relative to the comps in the subject's GLA tier. There is a reason it is adjusting high - the GLA difference did not account for the 'gap-up" in the pricing structure. If you look for it, you will see it.
