What Is a Hybrid Appraisal
A hybrid appraisal splits the traditional appraisal process into two parts. First, a trained third party visits the property to collect detailed data about its condition, features, and measurements. Then, a licensed appraiser uses that data along with market research to determine the property's value without visiting the property themselves.
The data collector could be a real estate agent, insurance inspector, home inspector, or even another appraiser. They take photos, measure rooms, note the property's condition, and document features like flooring, fixtures, and any needed repairs. This information gets submitted to Fannie Mae's Property Data API.
The appraiser receives this data package and combines it with comparable sales research, neighborhood analysis, and other market data to complete the valuation. The effective date of the appraisal is when the appraiser finalizes their opinion of value, not when the data was collected.
When Hybrid Appraisals Are Available
You cannot simply request a hybrid appraisal. Desktop Underwriter must offer it as an option after analyzing your loan application. DU will send a message listing your appraisal options, which might include hybrid, desktop, or traditional appraisals.
Hybrid appraisals work for most standard transactions. You can use them for purchases, limited cash-out refinances, and cash-out refinances on single-family homes, condos, and PUD units. The property can be your primary residence, second home, or investment property.
They also work for some special situations. Properties under construction, homes with incomplete renovations, and community land trust properties are eligible. Texas Section 50(a)(6) loans can use hybrid appraisals too.
What Properties Cannot Use Hybrid Appraisals
Several property types are off-limits for hybrid appraisals. You cannot use them for duplexes, triplexes, or fourplexes. Co-op units and manufactured homes are also ineligible.
Construction loans present another barrier. Proposed construction projects and construction-to-permanent loans cannot use hybrid appraisals. HomeStyle Renovation and HomeStyle Refresh loans are also excluded.
If your loan receives an "Ineligible" recommendation from DU or requires manual underwriting, hybrid appraisals are not an option.
Required Documents and Process
The hybrid appraisal process requires specific documentation and follows a strict sequence. Your lender must first obtain the property data collection and submit it to Fannie Mae's Property Data API. Only after this submission can they engage an appraiser to complete the hybrid appraisal.
The appraiser uses either Form 1004 Hybrid for single-family homes or Form 1073 Hybrid for condos. These forms require the same exhibits as traditional appraisals, plus one critical addition: an ANSI-standard floor plan.
The appraiser must document specific details in the Additional Comments section. They need to identify the assignment type as "Hybrid," confirm the data collection method was "Physical," provide the exact date of the property visit, and specify who collected the data using one of six approved categories: Appraiser, AppraiserTrainee, RealEstateAgent, HomeInspector, InsInspector, or Other.
Why Fannie Mae Created Hybrid Appraisals
Hybrid appraisals address several industry challenges. They can speed up the appraisal process by separating data collection from analysis. A data collector can visit the property quickly while the appraiser works on the valuation remotely.
This approach also helps in markets with appraiser shortages. Licensed appraisers can focus their time on analysis and valuation rather than driving to properties and taking measurements. The system leverages other real estate professionals who already visit properties regularly.
Fannie Mae maintains quality control through technology. All hybrid appraisals get submitted to the Uniform Collateral Data Portal and scored by Collateral Underwriter, their automated risk assessment system.
Potential Complications and Gotchas
The biggest risk with hybrid appraisals is coordination between the data collector and appraiser. If the data collection is incomplete or inaccurate, the appraiser may need to request additional information or even require a traditional appraisal instead.
Timing can create problems. The property data must be submitted to Fannie Mae's API before the appraiser can complete their work. Any delays in this submission will delay your closing.
Your lender remains responsible for verifying the accuracy of all property information, even though they did not collect it themselves. They must ensure the property meets Fannie Mae's eligibility requirements and maintain all life-of-loan representations and warranties.
Some borrowers worry about accuracy since the appraiser never visits the property. However, the data collector follows strict protocols, and the appraiser can request additional information if needed. If the hybrid approach does not provide sufficient information, the lender may need to order a traditional appraisal.
Representations and Warranties Relief
Hybrid appraisals that receive a Collateral Underwriter risk score of 2.5 or lower qualify for special protections. Fannie Mae provides enforcement relief for certain representations and warranties related to the property's appraised value.
This relief reduces your lender's risk, which can translate to better loan terms or faster processing. The automated scoring system evaluates the appraisal's quality and consistency with market data to determine eligibility for this relief.
The relief only applies to specific representations and warranties about property value. Other loan-level representations and warranties remain in full effect. For complete details, lenders should review [[A2-2-06]].

Overview
For certain loan casefiles, DU offers hybrid appraisals - an appraisal option requiring a property data collection. A hybrid appraisal reported on the Uniform Residential Appraisal Report (Hybrid) (Form 1004 Hybrid) or Individual Condominium Unit Appraisal Report (Hybrid) (Form 1073 Hybrid) must conform to B4-1.1-04, Unacceptable Appraisal Practices. The minimum scope of work for hybrid appraisals includes consideration by the appraiser of interior and exterior property data collection by a trained and vetted third party (such as a real estate agent, insurance inspector, appraiser, etc.). The appraiser relies on the data collected (and other sources if needed) to identify property characteristics including condition. The property data collection must comply with the Uniform Property Dataset and be delivered to the Fannie Mae Property Data API.
Completing the Hybrid Appraisal
Property data collection and the appraisal report are separate assignments and may be performed by different people. If the appraiser does not perform the data collection, the lender must share the property data collection with the appraiser at the time of engagement. The appraiser will use the data along with other third-party sources to develop the appraisal. The effective date of the hybrid appraisal is the date that the appraiser arrives at their opinion of value.
Note: If the appraiser is engaged as a property data collector and at a later date engaged as an appraiser, this is still considered a hybrid appraisal.
The lender remains responsible for verifying the accuracy of the property description and the completeness of the data including the condition and quality ratings as determined by the appraiser. The lender is also responsible for ensuring the property meets the property eligibility requirements in this Selling Guide. Lastly, the lender remains responsible for any life-of-loan representations and warranties that may apply to the property or the appraisal.
Exhibits: Form 1004 Hybrid and Form 1073 Hybrid require the same exhibits as traditional appraisals with the inclusion of a floor plan conforming to the ANSI standard. See B4-1.2-01, Appraisal Report Forms and Exhibits for additional information on exhibits and B4-1.3-05, Improvements Section of the Appraisal Report for additional information on the ANSI standard.
Entry of Appraisal Assignment Type: The appraiser must provide the Appraisal Assignment Type and supporting details (located in the Additional Comments section of the appraisal report) as shown in the following table.
"Hybrid"
"Physical"

"Appraiser"
"AppraiserTrainee"
"RealEstateAgent"
"HomeInspector"
"InsInspector" (*Insurance Inspector)

Note: For the Subject Property Data Collection Date, the appraiser must enter the date that the property data collection was performed. For the Subject Property Data Workforce, the appraiser must enter the Workforce indicated in the property data that is one of the six Required Entry enumerations listed above.
DU Messaging: For loan casefiles that are eligible for a hybrid appraisal option, DU will issue a message informing the lender they can obtain an appraisal reported on Form 1004 Hybrid or Form 1073 Hybrid. DU will also issue messages for other appraisal options. The lender may select from any of the options presented, which may include a hybrid appraisal, desktop appraisal, or traditional appraisal.

obtain a property data collection and successfully submit to the Fannie Mae Property Data API.
provide the property data collection to an appraiser for the completion of a hybrid appraisal based on property type using either Form 1004 Hybrid or Form 1073 Hybrid.
submit the hybrid appraisal to the Uniform Collateral Data Portal (UCDP).
perform an appraisal review in accordance with this Guide.
deliver the loan with the hybrid appraisal to Fannie Mae.
Note: A lender may obtain a hybrid appraisal if a loan loses value acceptance + property data eligibility after submitting the property data collection to the Property Data API. See
B4-1.4-11, Value Acceptance + Property DataB4-1.4-11, Value Acceptance + Property Datafor specific requirements.
Representations and Warranties
When a hybrid appraisal is reported on Form 1004 Hybrid or Form 1073 Hybrid and submitted through the UCDP, the appraisal will be scored by Collateral Underwriter (CU). All eligible loans with a hybrid appraisal receiving a CU risk score of 2.5 or less are eligible for enforcement relief of certain representations and warranties related to the appraisal value of the subject property (see A2-2-06, Representations and Warranties on Property Value for complete requirements and additional information).
