Big changes are coming to the residential appraisal process, and they are not optional or far off. Starting November 2, 2026, the way most appraisals are reported for conventional mortgage lending is going to change in a major way.
The residential appraisal system used by lenders is built around standardized reporting formats required by Fannie Mae and Freddie Mac, often called the GSEs.
Right now, most appraisals used for conventional lending are completed under a format known as UAD 2.6. This is the current standard appraisers use to report property condition, features, and market value in a structured way that lenders and the GSEs can review consistently.
UAD 2.6 has been the standard reporting format for GSE appraisals since the early 2010s, following its rollout by Fannie Mae and Freddie Mac as part of their uniform mortgage data initiatives. It replaced a wide range of inconsistent reporting styles and created a single standardized system that has been used across the conventional lending market for more than a decade.
Starting November 2, 2026, that system changes.
Fannie Mae and Freddie Mac will require all appraisals delivered for GSE-backed loans to follow a new reporting structure commonly referred to as UAD 3.6. After that date, UAD 2.6 reports will no longer be accepted for loans being sold into the secondary mortgage market.
This applies specifically to conventional loans that are delivered to the GSEs. It does not eliminate appraisals, but it does change the required reporting structure for most standard mortgage lending.
What Is Changing With UAD 3.6
UAD 3.6 is not just a new form. It is a shift to a dynamic, data-driven reporting structure.
Instead of a fixed static form that is completed the same way every time, the new system is built around structured data fields that adjust based on property characteristics and reporting requirements. Appraisers are no longer just filling out a single standardized form. They are entering consistent, structured data into a system designed to be used across the lending and secondary mortgage ecosystem.
In practice, this means more detailed reporting and a higher level of structured data capture throughout the appraisal process compared to current reporting standards.
This does not change how market value is developed, but it does change how much detail must be collected and entered into the appraisal report.
What This Means in the Field
The most immediate impact of UAD 3.6 is time.
Even when the inspection itself feels familiar, more of the appraisal process is now happening during the on-site portion of the work. Instead of capturing general observations and finalizing details later at the desk, appraisers are being asked to record more structured data in real time while on the property.
That shift alone increases the amount of time required on-site. More fields, more property-specific inputs, and more structured reporting all require slower, more deliberate data collection during the inspection.
There is also a learning curve. Early use of the system shows that the first several reports take longer while appraisers adjust to the format and software workflow. Efficiency improves with repetition, but the transition period does add real time pressure to each assignment.
Software and Lender Readiness
Adoption remains limited at this stage.
UAD 3.6 is currently in a controlled production environment, but overall volume remains very low compared to the long-established UAD 2.6 system. The majority of lending pipelines are still operating under legacy reporting workflows while systems, software platforms, and internal review processes continue to be updated.
Appraisal software providers are actively adapting their platforms, but the industry as a whole is still transitioning toward full readiness for the new standard.
Because of this, most assignments today are still being processed in the existing UAD 2.6 format unless specifically required otherwise.
What Happens After November 2, 2026
After the implementation date, UAD 2.6 reports will no longer be accepted for delivery to Fannie Mae and Freddie Mac.
This means that for conventional loans being sold into the secondary mortgage market, only UAD 3.6-compliant reports will be eligible for acceptance.
Loans that do not meet the new reporting requirements will not clear GSE delivery, which can affect underwriting completion and closing timelines if the proper format is not used.
Impact on Turn Times, Fees, and Capacity
UAD 3.6 adds more work to each appraisal due to increased data requirements and structured reporting.
In the short term, this is expected to affect turn times. Reports will likely take longer during the transition period as appraisers adjust to new data entry requirements and workflow changes.
The increased workload is expected to create upward pressure on appraisal fees in some markets as additional time and complexity become part of the standard process.
Overall capacity may also be affected temporarily as the industry adjusts to the new reporting demands.
Final Thoughts
UAD 3.6 represents a structural change in how appraisal data is collected and delivered for GSE lending. While the goal is improved consistency and better data quality, the short-term reality is more detailed reporting requirements and a learning curve for the industry.
Appraisers, lenders, and software providers are all working through the transition at the same time, which means workflow adjustments are ongoing.
For borrowers and clients, the key takeaway is simple. Appraisals are not going away, but the reporting process is becoming more detailed and structured, and that change is already underway.
