UAD 3.6 Reporting Requirements: What Appraisers, AMCs, and Lenders Need to Know?

For appraisers, Appraisal Management Companies (AMCs), and mortgage lenders, understanding the UAD 3.6 reporting requirements is becoming increasingly important. The transition involves more than learning a new report format. It also requires changes in appraisal software, data collection, report preparation, quality checks, and submission workflows.

As the industry prepares for the transition, businesses need to understand what is changing, how the new reporting structure works, and what steps they should take to prepare.

In this guide, we explain the key UAD 3.6 reporting requirements, the submission process, common challenges, and what the changes mean for different stakeholders in the valuation industry.

What Is UAD 3.6?

The Uniform Appraisal Dataset (UAD) is a standardized framework developed by Fannie Mae and Freddie Mac to collect and communicate appraisal data consistently.

UAD 3.6 is the updated version of this framework. It introduces a redesigned appraisal reporting structure supported by a standardized data format. It is intended to improve the consistency, clarity, and usability of appraisal information.

One of the most significant changes is the introduction of the redesigned Uniform Residential Appraisal Report (URAR). Instead of relying on several separate form types for different property and assignment scenarios, the new approach uses a more comprehensive and flexible reporting structure.

For industry professionals, this means becoming familiar with new data fields, reporting expectations, terminology, and submission requirements.

Why Are UAD 3.6 Reporting Requirements Important?

Accurate appraisal reporting plays an important role in mortgage lending decisions. Lenders rely on valuation information to understand property characteristics, assess collateral risk, and make informed lending decisions.

When appraisal information is inconsistent or incomplete, it can create additional work for appraisers, AMCs, and lenders. Missing details, incorrect data, and report inconsistencies may lead to clarification requests, revisions, and submission delays.

UAD 3.6 is intended to establish a more standardized approach to collecting and communicating appraisal data.

Understanding the new requirements can help businesses:

• Prepare their appraisal workflows for the updated reporting structure.
• Improve the consistency of property data.
• Reduce avoidable reporting errors and revisions.
• Prepare appraisal software and systems for the new format.
• Improve coordination between appraisers, AMCs, and lenders.
• Support more efficient appraisal review and submission processes.

What Are the Key UAD 3.6 Reporting Requirements?

UAD 3.6 introduces several important changes to appraisal reporting and submission. Understanding these requirements is essential for professionals involved in preparing, reviewing, and submitting appraisal reports.

1. New Uniform Residential Appraisal Report (URAR)

One of the most noticeable changes is the redesigned Uniform Residential Appraisal Report.

The new URAR is designed to accommodate different property types and appraisal assignment scenarios within a more flexible reporting structure.

Appraisers need to become familiar with the new report layout, data fields, and reporting expectations. They should also understand how property characteristics and assignment-specific information need to be documented.

2. MISMO 3.6 XML Data Format

UAD 3.6 uses the MISMO 3.6 data standard to structure appraisal information.

XML is used to organize the information in a standardized digital format. This allows appraisal data to be communicated between systems in a more consistent and structured way.

Appraisal software providers, lenders, and other technology partners need to ensure their systems can support the updated format.

3. XML, PDF, and Image File Submission

The UAD 3.6 submission process has specific file packaging requirements.

A UAD 3.6 submission to the Uniform Collateral Data Portal (UCDP) must be packaged as a ZIP file containing:

• UAD 3.6 XML: The structured appraisal data.
• PDF report: A PDF version of the appraisal report.
• Images folder: A dedicated folder named Images containing the applicable appraisal images.

The Images folder name is case-sensitive. Images are provided separately rather than embedded in the XML file.

The ZIP file must also meet the applicable portal requirements, including the maximum file size of 60 MB.

4. Accurate Property Information

Accurate property information remains a critical part of appraisal reporting.

Appraisers need to ensure that property characteristics, improvements, condition, location details, and other relevant information are documented correctly.

Incomplete or inconsistent information can create questions during the review process and may require additional clarification.

5. Property Photos and Supporting Images

Property images are an important part of the appraisal report because they provide visual support for the property’s condition and characteristics.

Under the UAD 3.6 submission structure, applicable images are included in the dedicated Images folder within the ZIP package.

Appraisers and their support teams should make sure that images are organized correctly and correspond with the information presented in the report.

6. XML and PDF Consistency

The structured XML data and the PDF report must accurately represent the same appraisal information.

The PDF must be a native, first-generation version of the report. It must not be password-protected or encrypted.

Before submission, teams should check that the information in both files is consistent. Differences between the XML and PDF can create submission or review issues.

7. UCDP Submission and Validation

The Uniform Collateral Data Portal (UCDP) is used by lenders to submit appraisal data to the GSEs.

UAD 3.6 submissions are subject to applicable portal validation and review findings. These include UAD Compliance Findings, System Findings, and GSE Proprietary Findings.

Reviewing the Submission Summary Report (SSR) and addressing applicable findings are important parts of the submission process.

UAD 2.6 vs. UAD 3.6: What Is Changing?

Understanding the difference between UAD 2.6 and UAD 3.6 can help appraisal professionals prepare for the transition.

The transition is not simply a change in file format. It represents a broader update to how appraisal information is collected, organized, and communicated.

UAD 3.6 Implementation Timeline

Understanding the transition timeline is important for businesses planning their software updates, training, and operational readiness.

• January 26, 2026: The GSEs’ UAD 3.6 limited production period began.
• November 2, 2026: UAD 3.6 becomes mandatory for new appraisal report submissions to UCDP, subject to applicable lender policy exceptions.
• May 3, 2027: The scheduled end of the UAD 3.6 transition period.

Eligible lenders may have access to a temporary policy exception affecting the format they request. However, such an exception does not change the appraiser’s responsibility to adopt UAD 3.6.

Businesses should confirm the latest requirements and applicable policies with the relevant GSE resources and their lender partners.

How Will UAD 3.6 Affect Appraisers?

Appraisers will be directly involved in implementing the updated reporting requirements. They need to understand the new report structure, become comfortable with the updated data fields, and ensure their software supports the required format.

Some important areas of preparation include:

• Learning the redesigned URAR and its reporting sections.
• Understanding updated property data requirements.
• Reviewing how property characteristics and condition are documented.
• Ensuring photos and supporting information are organized correctly.
• Checking XML and PDF consistency before submission.
• Becoming familiar with UCDP validation findings.

For many appraisal professionals, the biggest adjustment will be incorporating these requirements into their existing daily workflows without affecting turnaround times.

How Will UAD 3.6 Affect AMCs?

Appraisal Management Companies coordinate appraisal assignments between lenders and appraisers. They also manage operational workflows, report reviews, communication, and quality control.

With UAD 3.6, AMCs may need to review their existing processes and identify where additional checks or workflow adjustments are required.

Important considerations include:

• Preparing internal teams to understand the new reporting structure.
• Reviewing appraisal software and technology compatibility.
• Updating quality control and review processes.
• Monitoring missing information and reporting inconsistencies.
• Coordinating with appraisers and lender partners.
• Managing operational workloads during the transition.

AMCs that prepare their teams and processes early can be better positioned to manage the reporting transition efficiently.

How Will UAD 3.6 Affect Mortgage Lenders?

Lenders need to ensure their appraisal submission workflows and technology systems are ready for UAD 3.6.

They should work with their technology providers, appraisal partners, and internal teams to understand the updated submission requirements.

Key areas of focus include:

• Confirming UAD 3.6 compatibility with appraisal technology systems.
• Preparing teams for the updated UCDP submission process.
• Reviewing appraisal data and report consistency.
• Understanding updated UCDP findings and SSR information.
• Communicating transition expectations to appraisal partners.

Clear coordination between lenders, AMCs, and appraisers will be important for maintaining smooth appraisal operations.

Common UAD 3.6 Transition Challenges

Although UAD 3.6 is designed to improve appraisal data consistency, the transition may create operational challenges for businesses that are not fully prepared.

1. Understanding the New Reporting Structure

Teams familiar with the existing appraisal forms may need time and training to understand the redesigned URAR and its updated data fields.

2. Technology and Software Compatibility

Appraisal platforms and internal systems need to support the updated data standard and submission requirements. Businesses should coordinate with their technology providers to confirm readiness.

3. Maintaining Data Accuracy

New reporting expectations can create questions during the initial adjustment period. Teams need to pay attention to missing information, inconsistent entries, and incorrect property details.

4. Managing Operational Workloads

Training, report preparation, quality checks, and additional communication can increase workloads during the transition. Businesses may need to review how administrative responsibilities are distributed across their teams.

5. Avoiding Submission Delays

Incorrect file packaging, incomplete images, or inconsistencies between XML and PDF files can create submission problems. A consistent pre-submission review process can help identify issues earlier.
