I think others have said it before me appraising for GSE's will morph into 2 fields that being data collection and analysis. Data collectors will get paid less and you won't need a degree. Analytical professionals will probably need a degree and get paid more. Timeline perhaps 5year +-?
You are dreaming. If they morph "appraising into two fields, " it will be low-paid data collectors ( who often are not even appraisers ), and "analytical professionals might not be appraisers either, in order for them be equally low paid. It's all about siphoning control and money away from appraisers to third parties.
If they allow the so-called data analysis as a segment for appraisers, it will not require a degree. It is not rocket science to determine a time adjustment or other adjustment, especially if one relies on the software programs that spit it out. Appraising should imo require a degree as an entry barrier for claiming it is needed for data analysis is not the reason.
What makes an appraiser uniquely suited for their role is not segmenting an appraisal into fast-food sections to churn out for "efficiency".
What makes an appraiser good at their job is the integration of first-hand field experience with the ability to analyse data, and then interpret it through cumulative observatoin of and interactions with market participants. Education helps, of course, but poorly qualified people can memorize enough to pass a test to get a license, yet still not grasp the fundamentals, as we see from the clueless questions here.
Every decision over the past decade-plus made by the GSEs and their affiliates has been to lower the education standards, not raise them. That they influxed a mass of non-appraisers to "data collect" for low fees, which serves to cut the appraiser off from inspecting the subject of their own appraisal in a hybrid says it all.
