New 2026 Home Appraisal Guidelines: What South Bay Buyers & Sellers Need to Know
New Home Appraisal Guidelines Are Coming: What South Bay Buyers and Sellers Should Know
A major modernization of residential appraisal reporting is approaching. The changes are designed to create better, more consistent property data—but the transition could also affect how appraisals are prepared, reviewed and potentially how long some homes take to close.
For homeowners, buyers and sellers in Palos Verdes Estates, Rancho Palos Verdes, Rolling Hills, Rolling Hills Estates, Manhattan Beach, Hermosa Beach, Redondo Beach, Torrance and throughout the South Bay, this is an important behind-the-scenes change to understand.
Updated September 2026 • By Cliff Scherb, Scherb Homes Group, Vista Sotheby’s International RealtyWhat Is Changing With Home Appraisals?
Fannie Mae and Freddie Mac are implementing a significant modernization of the Uniform Appraisal Dataset, known as UAD 3.6, along with a redesigned Uniform Residential Appraisal Report, or URAR.
For decades, residential appraisals have relied on familiar standardized forms. The new system moves away from many of those static forms and toward a more flexible, data-driven appraisal report designed to capture property characteristics in greater detail and in a more standardized way.
According to Freddie Mac, the redesign replaces existing GSE appraisal forms with a single flexible and dynamic report that can accommodate different property types and valuation methods. The new system also provides substantially more structured property data.
New Data Standard
UAD 3.6 creates a more detailed and standardized structure for residential appraisal information.
Dynamic Report
Many legacy appraisal forms are being replaced by the redesigned Uniform Residential Appraisal Report.
Key 2026 Date
November 2, 2026 is the mandatory UAD 3.6 submission date for new appraisal reports submitted to the GSE portal.
This is not simply a new-looking appraisal form. It is a significant change in how property information is collected, organized, communicated and reviewed throughout the mortgage process. Buyers and sellers may barely notice some transactions, while others—particularly unusual or complex properties—could require more preparation and coordination.
The Appraisal Transition Timeline
The industry is already transitioning. Broad production of UAD 3.6 began in 2026, allowing lenders and their appraisal partners to gain experience before the mandatory implementation date.
Lenders became eligible to submit appraisal reports using the redesigned UAD 3.6 standard.
Lenders, appraisal management companies, appraisers and software providers have been updating systems and workflows.
New appraisal reports submitted to the Uniform Collateral Data Portal must use UAD 3.6.
The transition continues after the November mandate for certain revisions to previously submitted legacy reports.
Freddie Mac has specifically cautioned industry participants that training, testing and transitioning can take longer than expected. That does not mean every consumer should expect a delayed transaction, but it is one reason we believe buyers and sellers should understand the transition before entering escrow.
A More Detailed, Data-Driven Appraisal
One of the biggest differences is the shift away from relying heavily on free-form commentary. More information about the property can now be captured as structured data.
What the modernization is designed to accomplish
- Create more consistent appraisal data across property types.
- Provide more granular information about the subject property.
- Improve appraisal review and quality-control processes.
- Reduce reliance on miscellaneous free-form appraisal commentary.
- Allow technology to analyze property information more effectively.
- Support a wider range of property types and valuation methods within a common reporting framework.
- Improve the clarity of condition and quality information.
FHFA has described the modernization as an opportunity to move important information from narrative commentary into discrete data points, potentially supporting better data analysis, automated workflows and risk review.
In the long run, that could make appraisal review more efficient. During the transition, however, there will naturally be a learning curve as appraisers, lenders, agents and other participants become familiar with the new process.
More Detail About the Home May Matter
The new framework captures more granular information about property characteristics. Freddie Mac's guidance notes changes involving areas such as condition reporting, property components, measured square footage and supporting property information.
Condition & Quality
The familiar condition and quality rating scales remain, but definitions have been clarified and the redesigned system can distinguish between interior and exterior condition where appropriate.
Property Components
More granular component-level information can help support an appraiser's overall assessment of the home's condition and quality.
Square Footage
Reporting requirements for measured square footage are part of the updated framework, making accurate property information increasingly important.
Photos & Supporting Data
UAD 3.6 submissions include structured appraisal data, the appraisal report and associated images, creating a more comprehensive digital appraisal package.
This reinforces something we already believe strongly in: a listing agent should understand the property before the home reaches the market. Improvements, permits, square footage, condition, special features, renovations, views, lot characteristics and relevant comparable sales should be organized rather than reconstructed at the last minute when an appraiser arrives.
What South Bay Home Sellers Should Know
The appraisal remains one of the important checkpoints in a financed home sale. If a buyer is obtaining a conventional mortgage, the lender may need an appraisal to support the collateral value of the property.
For sellers, the new guidelines make thoughtful property preparation and documentation even more valuable.
Before Listing
- Review the home's known square footage and public-record information.
- Organize major renovation and improvement information.
- Identify permits or documentation when available.
- Understand which property characteristics add measurable market value.
Before the Appraisal
- Prepare a concise property improvement summary.
- Provide relevant factual information through appropriate channels.
- Identify strong comparable sales and meaningful differences.
- Make the property easy for the appraiser to inspect thoroughly.
This is particularly important in the luxury and coastal markets we serve. Two homes with similar square footage can have dramatically different values because of street location, ocean or city views, lot usability, privacy, architectural quality, remodeling, school proximity, walkability or neighborhood micro-location.

What Buyers Should Know About the New Appraisal Process
Buyers should not interpret the new appraisal framework as a reason to avoid financing or expect every transaction to become complicated. The larger issue is preparation.
During the transition, buyers should work with lenders who understand the new requirements and are actively prepared for UAD 3.6. Buyers should also understand where the appraisal falls within their contingency and closing timeline.
Questions buyers may want to ask their lender
- Is your appraisal department fully prepared for UAD 3.6?
- Is the assigned appraisal vendor or appraiser working with the new report?
- What is the expected appraisal turn time?
- How quickly will the lender review the completed appraisal?
- What happens if a correction or revision is requested?
- Does our contractual closing timeline provide sufficient room?

Could These Changes Make Homes Take Longer to Close?
Possibly—especially during the transition—but we do not yet believe anyone can responsibly say that every transaction will take longer.
This distinction is important. The new system is ultimately intended in part to improve data quality and streamline review. In the near term, however, major industry changes can create friction while thousands of appraisers, lenders, appraisal management companies and software systems adapt.
Potential Sources of Delay
- Appraiser training and familiarity with the redesigned report.
- Lender or appraisal-management workflow changes.
- Software implementation issues.
- More detailed property research.
- Additional questions or revision requests.
- Complex or unusual properties requiring additional analysis.
Potential Long-Term Benefits
- More standardized property information.
- Better machine-readable appraisal data.
- Clearer quality-control review.
- Fewer ambiguities buried in commentary.
- Potentially fewer clarification requests as the system matures.
Our working assumption at Scherb Homes Group is that it is prudent to build a little more awareness—and potentially more flexibility—into appraisal and loan timelines as the November 2026 mandate approaches. We are not saying every escrow needs to become longer. We are saying that promising an aggressive closing date without first understanding the buyer's lender and appraisal process may become increasingly risky during the transition.
This becomes even more relevant in a South Bay market where homes are already taking different amounts of time to sell depending on neighborhood, price and property type.

The Real Estate Agent's Role May Become More Important, Not Less
Appraisers are independent valuation professionals. A real estate agent should never attempt to improperly influence an appraiser's conclusion.
Good representation does, however, mean making sure relevant factual property and market information is organized and available through appropriate channels.
For listing agents, that can mean:
- Understanding the home's physical characteristics before listing.
- Researching relevant comparable sales beyond superficial price-per-square-foot comparisons.
- Knowing the property's improvements, renovations and material features.
- Understanding the micro-location and why one nearby sale may not be truly comparable.
- Communicating factual property information clearly.
- Preparing sellers for the appraisal process before entering escrow.
- Monitoring appraisal timing closely once the property is under contract.
For buyer agents, that can mean:
- Understanding how appraisal contingencies interact with the offer strategy.
- Communicating with the lender early.
- Evaluating comparable sales before writing an aggressive offer.
- Helping the buyer understand appraisal risk in multiple-offer situations.
- Monitoring lender, appraisal and contractual deadlines throughout escrow.
More data does not eliminate the need for local expertise. In markets like Palos Verdes and the South Bay, interpreting the data is often the difficult part. A view, a quiet interior street, a usable lot, proximity to the ocean, a particular school pocket or even which side of a street a home sits on can materially affect buyer behavior. Technology can organize information, but experienced local interpretation remains important.
Why This Could Matter More in Palos Verdes and the South Bay
Our local housing stock is unusually diverse. Palos Verdes alone includes mid-century homes, Spanish architecture, ocean-view estates, equestrian properties, hillside homes, remodeled ranch homes, properties with additions and homes built across dramatically different lot configurations.
The Beach Cities introduce another set of variables: Sand Section versus Hill Section, walkability, ocean proximity, lot orientation, views, attached versus detached housing, newer construction and substantial differences between individual streets.
That makes comparable-sale selection and property-level analysis especially important.
Palos Verdes
Views, lot usability, topography, street location, architecture, privacy and neighborhood can create large valuation differences.
Beach Cities
Walkability, ocean proximity, section, lot size, views, age and construction quality can dramatically influence buyer demand.
Luxury Homes
Unique properties frequently have fewer truly comparable sales, increasing the importance of detailed property and market analysis.

We are continuing to follow the rollout closely. There are aspects of the consumer-level impact that will only become clear as the industry gains experience with the new system. Our view today is therefore intentionally practical: prepare early, document properties carefully, communicate with lenders and appraisers appropriately, and avoid assuming yesterday's appraisal timeline will automatically apply to every transaction tomorrow.
