UAD 3.6 Appraisal Changes: What Mortgage Professionals Need to Know Before November 2, 2026

How the New Uniform Appraisal Dataset (UAD) Changes Residential Mortgage Appraisal Reports, Traditional Appraisal Forms, and the Lending Process, and why SAFE Exam Candidates Should Understand These Changes

The residential mortgage appraisal process is undergoing one of its most significant reporting transformations in decades.

Beginning November 2, 2026, Fannie Mae and Freddie Mac will require the new Uniform Appraisal Dataset (UAD) 3.6 for applicable new appraisal reports submitted through the Uniform Collateral Data Portal (UCDP), subject to approved temporary lender exceptions. [1]  For mortgage loan originators (MLOs), appraisers, lenders, and borrowers, this change introduces a redesigned appraisal report, more structured property information, and new electronic submission requirements.

For individuals preparing to take the National SAFE Mortgage Loan Originator Test, the transition also represents an important development in current mortgage industry practices.

But does UAD 3.6 change how homes are valued?  Will traditional appraisal forms disappear?  And what should mortgage professionals expect during the transition?  Let’s examine what’s changing and why it matters.

What Is UAD 3.6?

The Uniform Appraisal Dataset 3.6 is an updated standardized framework developed jointly by Fannie Mae and Freddie Mac to modernize residential appraisal reporting.  The initiative is part of the Uniform Mortgage Data Program (UMDP), undertaken at the direction of the Federal Housing Finance Agency (FHFA).

UAD 3.6 aligns appraisal data with the Mortgage Industry Standards Maintenance Organization (MISMO) Reference Model 3.6 and introduces a redesigned Uniform Residential Appraisal Report (URAR). [2]

Under the previous UAD 2.6 system, appraisers relied on established forms, standardized abbreviations, narrative explanations, and supporting addenda.  UAD 3.6 introduces a more flexible, data-driven approach.

Rather than organizing the report primarily around a predetermined form, the redesigned system organizes information around the characteristics of the property and the appraisal assignment.  The objective is to improve the consistency, clarity, and usefulness of appraisal information throughout the mortgage lending process.

When Does UAD 3.6 Become Mandatory?

The transition has progressed in stages.

Date		Implementation Milestone
September 8, 2025		Limited production began for approved lenders
January 26, 2026		Broad production began
November 2, 2026		UAD 3.6 mandate for applicable new UCDP submissions
May 19, 2027		End of the announced temporary policy exception period

The November 2^nd mandate is based on the appraisal report’s initial submission date to UCDP, rather than the date the appraisal was ordered or the property was inspected. [3]

Important: Temporary Lender Exceptions

On September 30, 2026, Fannie Mae and Freddie Mac announced a temporary policy exception for lenders that need additional time to complete their transition.  Lenders that request and qualify for the exception may continue submitting UAD 2.6 appraisal reports through May 19, 2027, under the applicable requirements. [4]  This is not, nor should it be construed as, a universal postponement of the mandate.  Lenders should confirm whether an exception applies to their organization and follow the appropriate GSE requirements.

The exception also does not eliminate the broader industry responsibility to prepare for UAD 3.6.

How Does UAD 3.6 Change Traditional Residential Appraisals?

1. Traditional Appraisal Forms Are Being Replaced

One of the most recognizable changes is the replacement of traditional appraisal form numbers with a redesigned Uniform Residential Appraisal Report.

Mortgage professionals have long been familiar with forms such as:

• Form 1004: Uniform Residential Appraisal Report (URAR)
• Form 1073: Individual Condominium Unit Appraisal Report
• Form 1025: Small Residential Income Property Appraisal Report
• Form 1004C: Manufactured Home Appraisal Report

Under UAD 3.6, the redesigned URAR replaces these and other legacy GSE appraisal reporting forms.  The new report adjusts to the property and assignment rather than requiring an entirely different fixed form for each property category. [5]

For example, a condominium appraisal and a manufactured home appraisal will not necessarily contain identical information.  However, both will use the standardized UAD 3.6 reporting framework.  This change is intended to make appraisal reporting more consistent while accommodating differences among residential property types.

2. More Detailed Property Characteristics

The UAD 3.6 introduces a more structured method for describing property characteristics.  Traditional appraisal reports have often relied on abbreviated descriptions, standardized ratings, and supplemental narrative commentary.  The redesigned system captures more information through defined data fields.

For example, information concerning a property’s location, views, and site influences can be described with greater specificity.  Rather than relying solely on a general view classification, the redesigned reporting framework allows appraisers to identify relevant characteristics and describe their influence on the property. [6]  A property overlooking a lake, for instance, may have its view characteristics documented in greater detail.  The goal is not simply to collect more information.  It is to make relevant property information clearer and easier to interpret.

3. A Flexible, Dynamic Appraisal Report

Traditional appraisal forms generally follow fixed layouts.  When a property presents unusual characteristics, appraisers may need additional explanations or addenda.  The UAD 3.6 introduces a dynamic reporting structure.

The information displayed depends on the property and the appraisal assignment.  For example, a property containing an accessory dwelling unit (ADU) may require reporting elements that do not apply to a property without an ADU.  Similarly, manufactured homes and condominium units have characteristics requiring different information.  The redesigned URAR accommodates these differences within a common reporting framework. [2]

This is an important distinction: UAD 3.6 standardizes the reporting structure without requiring every property to be described identically.

4. Changes to Electronic Appraisal Submission

The transition also changes how appraisal information is submitted electronically.  Under UAD 2.6, appraisal submissions generally use an XML file containing an embedded PDF.  Under UAD 3.6, submissions use a ZIP package containing:

• Structured UAD 3.6 XML data;
• A PDF representation of the redesigned URAR; and
• An image folder containing associated images.

These changes affect the technology and workflows used by appraisers, appraisal management companies, and lenders. [7]  Software systems must support the updated data requirements and submission format.

Consequently, organizations should ensure their technology providers and appraisal partners are prepared for the transition.

5. More Consistent Appraisal Review

One of the intended benefits of the UAD 3.6 is improved data quality and consistency.  Structured information can help lenders and appraisal review systems evaluate property characteristics and identify information requiring additional attention.  For example, more detailed reporting may help reviewers understand differences between the subject property and comparable sales.  The UAD 3.6 does not, however, eliminate professional appraisal judgment.  Appraisers must still analyze relevant market information, evaluate comparable properties, and develop credible opinions of value.

The new reporting system changes how appraisal information is collected and communicated.  It does not replace the fundamental principles of real estate valuation.

What Does UAD 3.6 Mean for Mortgage Loan Originators?

Although MLOs do not prepare appraisal reports, understanding UAD 3.6 is important for several reasons.

Understanding the Redesigned Report

Mortgage loan originators should become familiar with the new URAR.  The report’s appearance and organization may differ substantially from the traditional appraisal forms MLOs have encountered throughout their careers.  Understanding where important information appears can help MLOs communicate more effectively with borrowers and lending partners.

Explaining Changes to Borrowers

Borrowers may notice that their appraisal reports look different.  An informed MLO can explain that the redesigned report is part of a broader modernization of residential mortgage appraisal reporting.  Importantly, the new format does not automatically increase or decrease a property’s market value.

Monitoring Appraisal Processing

During the transition, lenders and appraisal providers may adjust software systems, submission procedures, and internal workflows.  MLOs should monitor lender communications and remain attentive to appraisal-related processing issues.  There is, however, no basis for assuming that the UAD 3.6 will automatically increase or decrease appraisal turnaround times.

Understanding Which Loans Are Affected

The November 2^nd mandate concerns applicable appraisal submissions associated with Fannie Mae and Freddie Mac.  Mortgage professionals should not assume that identical requirements automatically apply to every FHA, VA, USDA, or other mortgage transaction.  Applicable agency, investor, and lender requirements must be considered separately.

Will UAD 3.6 Change How Homes Are Valued?

One of the most important points for mortgage professionals and borrowers is that UAD 3.6 does not automatically change a property’s market value.  The new system primarily changes the collection, organization, presentation, and electronic delivery of appraisal information.  Appraisers must still develop credible opinions of value using appropriate appraisal methods and professional judgment.  Comparable sales, property condition, location, market trends, and other relevant characteristics remain important considerations.  The redesigned reporting structure may make certain aspects of the appraisal analysis more transparent, but it does not guarantee a higher or lower valuation.

How Should Mortgage Professionals Prepare?

Preparation should focus on understanding the redesigned report and confirming that the appropriate operational systems are ready.  Appraisers should review the official UAD 3.6 reporting specifications, implementation guides, and training resources.  Lenders and appraisal management companies should confirm software compatibility and establish appropriate submission procedures.

Mortgage loan originators should become familiar with the new report, monitor lender guidance, and be prepared to explain relevant changes to borrowers.

Fannie Mae and Freddie Mac maintain official implementation resources and frequently asked questions addressing the transition. [8]

Because policy guidance can change, mortgage professionals should verify current requirements before relying on any implementation date or exception.

Could UAD 3.6 Appear on the SAFE Mortgage Loan Originator Exam?

Yes.  UAD 3.6 should be treated as potentially testable mortgage industry knowledge once the new requirements take effect on November 2, 2026.

The National SAFE Mortgage Loan Originator Test evaluates mortgage loan originator knowledge, including residential mortgage lending principles, appraisal-related concepts, and applicable industry requirements.

Because the examination is intended to reflect current mortgage industry knowledge, candidates preparing for examinations administered on or after November 2^nd should familiarize themselves with UAD 3.6 and its effect on residential appraisal reporting.

SAFE exam test candidates should understand:

• What UAD 3.6 represents and why it was introduced;
• How the redesigned Uniform Residential Appraisal Report (URAR) replaces traditional appraisal forms;
• How the new reporting structure differs from UAD 2.6;
• The November 2^nd implementation requirement and applicable temporary lender exceptions; and
• Why UAD 3.6 changes appraisal reporting without fundamentally changing how market value is determined.

Although no particular examination question can be guaranteed, understanding these changes is a sensible part of preparing for an examination that addresses current residential mortgage lending practices.

If you’re taking the SAFE exam on or after November 2, 2026, don’t overlook this important industry development.

Does UAD 3.6 Change the Three Traditional Approaches to Appraising?

No.  UAD 3.6 does not eliminate or replace the three established approaches to real estate valuation:

• The Sales Comparison Approach;
• The Cost Approach; and
• The Income Approach.

Appraisers continue to apply the approaches appropriate to the property and appraisal assignment.  What changes under UAD 3.6 is how appraisal information and supporting analyses are structured, documented, and reported through the redesigned Uniform Residential Appraisal Report (URAR).

The Bottom Line: A Major Change in Residential Appraisal Reporting

UAD 3.6 represents a significant modernization of the conventional residential mortgage appraisal reporting system.  By replacing traditional fixed forms with a flexible, standardized reporting framework, Fannie Mae and Freddie Mac intend to improve appraisal data consistency, clarity, and electronic processing.

For mortgage loan originators, understanding the change is part of maintaining professional competence in an evolving industry.

For SAFE exam candidates, it is also an opportunity to become familiar with an important development in contemporary residential mortgage lending.

The fundamental takeaway is straightforward:

Residential appraisal principles remain, but the way appraisal information is documented, organized, and delivered is changing substantially.

The UAD 3.6 is the updated Uniform Appraisal Dataset developed by Fannie Mae and Freddie Mac to modernize residential appraisal reporting.  It introduces a standardized, flexible reporting structure designed to improve data consistency and electronic processing.  The redesigned Uniform Residential Appraisal Report replaces numerous legacy GSE appraisal forms. [2][5]

2. Is UAD 3.6 mandatory beginning November 2, 2026?

Yes.  November 2, 2026, is the mandate date for applicable new appraisal submissions through the UCDP.  Qualifying lenders may, however, request a temporary policy exception allowing continued UAD 2.6 submissions through May 19, 2027.  The exception is not automatic. [3][4]

3. Will the traditional Form 1004 appraisal disappear?

The traditional Form 1004 is among the legacy appraisal forms being replaced by the redesigned Uniform Residential Appraisal Report (URAR) under UAD 3.6.  Instead of selecting a fixed form number, the new reporting structure adjusts to the property characteristics and appraisal assignment.  The underlying professional appraisal process remains necessary when an appraisal is required. [5]

4. Will UAD 3.6 change a home’s appraised value?

Not automatically.  UAD 3.6 changes how appraisal information is collected, organized, and reported.  It does not independently change a property’s market value.  Appraisers continue to analyze market conditions, comparable properties, and other relevant factors when developing opinions of value.

5. How will the UAD 3.6 affect mortgage loan originators and borrowers?

MLOs will need to become familiar with the redesigned appraisal report and their lenders’ transition procedures.  Borrowers may receive reports with different layouts and more detailed property information.  Lenders and appraisal providers may also adjust their technology and workflows.  MLOs should follow applicable lender guidance and communicate accurately with borrowers about the changes.
