UAD 3.6: Your Questions Answered

Since publishing our UAD 3.6 Readiness Guide, we’ve heard from a lot of lenders and AMCs working through their compliance planning. Some questions come up repeatedly. We’ve pulled together the most common ones here. 

When exactly does UAD 3.6 take effect? 

November 2, 2026 is the mandatory effective date. All new appraisals submitted to UCDP or EAD on or after that date must use UAD 3.6 format. There is no grace period and no extension process. 

One important nuance: appraisals ordered before November 2 but submitted after may still require UAD 3.6 compliance depending on your investor guidelines. Check with your compliance team and investors now — don’t assume the order date determines the format requirement. 

Does UAD 3.6 apply to all loans? 

If the loan will be sold to Fannie Mae or Freddie Mac, yes. Government-backed loans — FHA, VA, USDA — operate under separate appraisal requirements and are not subject to this mandate. Your investor guidelines take precedence, so confirm with your compliance team which loan products are in scope. 

We’re not a lender — we’re an AMC. Does this apply to us? 

Yes. If you’re an AMC serving GSE-eligible lenders, you must ensure the appraisals you manage and deliver are UAD 3.6 compliant. The mandate flows downstream. Your software vendor, forms provider, and appraiser network all need to be aligned. 

What systems need to be updated? 

More than most people initially assume. Your Appraisal Management Software (AMS) needs to support the UAD 3.6 XML schema. Your forms software — whatever appraisers use to complete reports — must be updated. Your UCDP/EAD integrations must handle the new submission protocols and delivery format. And any QC tools that process or review appraisal data need to be compatible. 

If any link in that chain isn’t ready, you have a compliance gap — even if your AMS itself is updated. 

My current vendor says they’ll be ready. How do I verify that? 

Get a specific date, in writing, and request access to a test environment. The right question isn’t “will you be ready?” — it’s “when can I start submitting UAD 3.6 test transactions through your sandbox?” If your vendor can’t answer that by summer, your timeline is at risk. 

What happens if a submission fails UCDP validation under UAD 3.6? 

The GSEs reject the appraisal. It cannot be used for the loan. You’ll need to order a new appraisal — from an appraiser who may already be managing a full queue in a tight market. That adds days or weeks to your closing timeline, risks rate lock expiration, and creates repricing exposure. 

Post-deadline, repeated non-compliant submissions can also flag your institution for additional GSE review. The operational and regulatory costs compound quickly at volume. 

Can we run UAD 2.6 and UAD 3.6 orders at the same time during transition? 

Yes, and you’ll likely need to. For a period before the November 2 deadline, both formats may exist in your pipeline simultaneously — older orders under UAD 2.6, newer orders under UAD 3.6. Your platform needs to handle both without errors or confusion. This is a specific capability to validate with your vendor. 

We’re a smaller lender. Do we have the same obligations as large institutions? 

The compliance requirement is the same regardless of loan volume. Every lender selling conventional loans to Fannie Mae or Freddie Mac must be UAD 3.6 compliant by November 2. There are no volume-based carve-outs. 

If anything, smaller lenders face a tighter risk profile — fewer resources to absorb a failed submission wave, and less operational bandwidth to manage a platform transition under deadline pressure. Starting now matters more, not less. 

What’s the most common mistake lenders make during compliance transitions like this? 

Treating it as a platform-only problem. UAD 3.6 requires your AMS to be updated — but it also requires your appraisers to know the new requirements, your QC team to update their workflows, your compliance team to review investor guidelines, and your operations team to have a fallback plan if something goes wrong in October. 

The lenders who get caught flat-footed are usually the ones who assumed their vendor would handle it. The vendor handles the technology. The operational readiness is yours. 

Where do I start?
