Beginning in
February 2025, appraisers will be required to provide support for time value adjustments for comparable sales (comps) and market conditions—and also
include an illustration of the methodology used.
If we can have a program that says and does this and puts in the numbers, life gets easier. If you have to figure out yourself all this and write it, no extra pay for extra time spent. Also, this is showing you that fannie has the program to burn you. And of course, their avm will have this. Another domino falls to end of appraisers.

This is how I've looked at market adjustments since the 90s. There have always been places to get graphs like this or construct one on your own. My Board of Realtors published yearly median/average sale price graphs broken down by MLS area as far back as the 80s. They also published quarterly sales statics. They did the work - not me. I just had to ANALYZE that data/graph and see how it applied to my subject.
Nowadays, I'm pretty sure most of us can export/import raw MLS data into an Excel spreadsheet and run all sorts of analysis and get granular data like this in a few minutes, once you setup a template. This is our job - to analyze market data. How many times does USPAP use the word "analyze" in it?
Granted, this is easier in large population centers than in rural areas as the quantity of data. Statistics are only as good as the quantity and quality of the data available. However, the GSEs know that rural properties are a different beast and make allowances for the lack of quality data. This level of analysis is more geared towards where most appraisers are - in large population centers with hundreds to thousands of data points in any given period.
Markets practically never increase or decrease in a straight line so using such adjustments, while convenient, aren't really accurate. Given the vast amounts of data available to us nowadays, it's not unreasonable to expect better analysis from us.
The GSEs have algorithms and data to double check whether our adjustments look reasonable given the data they have. If you are making large market adjustments (or any adjustment for that matter) that fly in the face of their statistics, and you have no support or substantive analysis comments in your report, it's going to get flagged and scrutinized. But if you have a graph like this or other analysis that supports what you did in your report then it's going to be considered even if it doesn't line up with their data. In the end, WE have to support what we did. GSEs have support for why they are questioning it; you are supposed to have the data to support what you did.
If we don't want algorithms and CU taking over more of our jobs, or getting letter upon letter asking us to provide actual support for our adjustments - support that's supposed to already be in our work file - then start being the data analyst USPAP had always required us to be.
Our "experience" is only as good as our analysis capabilities. If you can't take data, crunch the numbers, and extract meaningful market data (or find a service that can do some of that for you), from which to support your adjustments/conclusions, then you are in the wrong profession.
All this does is require from us what USPAP always has - get data and analyze it. Technology is catching up with us and we have to adapt. Those who adapt will survive. Those who don't adapt, well....
