UAD 3.6 is mandatory in 24 days.

Not a soft cutover. Without a GSE exception, a 2.6 submission on or after that date is out of compliance with the Guides. If you are a lender, an AMC, or an appraisal firm still working files that will land in November, the exposure is already in your pipeline.

The date that matters is the submission date, not the effective date.

This is the detail that will cost people money. Eligibility is determined by when the report reaches the portal, not by when the appraisal was made, not by when the order was placed, and not by when the borrower applied.

For lenders without an exception, an appraisal with an October effective date, submitted on November 3, is not a 2.6 file that arrived slightly late. It is a file that cannot be delivered in the format it was written in.

Work backwards from that. The last business day before the cutover is Friday, October 30. Every order still in inspection, revision, or review that week is exposed, and revision cycles are exactly where files go to sit.

Got the exception? You now have two pipelines.

The exception isn't more time. It's a written commitment with a date on it. Until May 19, you're routing 2.6 and 3.6 by order, reviewing to two standards, and tracking which loans lose value R&W relief on March 1. Your panel needs to know which format you want on every order. Your investors will ask what you signed.

The assessment covers exception holders the same way: routing, review, pipeline exposure, and a cutover plan you can actually hit.

Book a readiness assessment

I have already written this document once.

When this mandate landed on a non-QM lender's desk, I authored the internal transition guide, the industry timeline, the platform alignment, and the operational impact laid out for appraisal, underwriting, quality control and technology, each of which breaks differently. An outside training contractor had been engaged to do that work. They withdrew, because it was already done.

That guide belongs to the company that paid for it, and it is not on this website. On a call I will take you through a sanitized version of what it covers. What I can do for you is the same work again, against your platform, your channels and your pipeline, and I can do it in the weeks that are left rather than the months it would have taken to learn the subject first.

What the field actually looks like

Of roughly 1,800 surveyed appraisers had completed an assignment in the new format as of March 2026.

58%

Had not completed the required seven-hour training.

What has to be ready

  1. Ordering logic, whether an order can even be placed in the new format, per channel.
  2. Vendor verification, which panel appraisers and AMCs can actually deliver 3.6 today.
  3. Review desk retraining, reviewers calibrated to a report that no longer looks like the form they learned.
  4. Pipeline exposure, every file that will still be open the week of October 30, identified now.
  5. The revision-and-resubmission path, who owns a Fatal comeback and what the clock looks like.
  6. Downstream systems, underwriting, QC and delivery logic that parses fields that moved.
