Hybrid Appraisal Property Data Collection Network

Asteroom has built a nationwide UAD 3.6 hybrid appraisal property data collection network over the past 7 years.

This specialized inspection network can deliver Uniform Property Data (UPD) reports nationwide for lenders wishing to (a) start or expand their use of inspection based appraisal waivers, and/or (b) take advantage of the GSE UAD 3.6 hybrid appraisal solutions.

Network Counties

Asteroom's property data collection network is drawn from over 35,000 users of its highly popular 3D Tour Kits and has currently completed inspections in over 2,500 counties. When new locations or counties are required, Asteroom can activate a new property data collection 

Property data collectors are licensed real estate professionals - such as real estate agents and notary signing agents - who are knowledgeable about single family residential property and accustomed to working with lenders,  borrowers, homeowners.

3D Property Scanning vs. Traditional Photos & Floorplans

A primary differentiator for Asteroom is its proprietary 3D property scanning technology.

Other hybrid inspection providers deliver static photos, form-based Q&A inspection reports with basic condition commentary. Asteroom takes a very different data-centric approach built around proprietary 3D scanning, layered quality control, and direct appraisal workflow integration.

An Asteroom scan captures the full UPD with a ‘once-through-the-property’ inspection. Rather than relying solely on static photos, form-filled data entry, separate floor plan videos, the platform creates:

• A 3D scan virtual walkthrough, with room-to-room spatial validation
• ANSI-aligned floor plans with internal measurements and layout verification
• Required data collection and photo images
• Prefilled UAD 3.6 URAR Hybrid Appraisal, and TOTAL Zap file

For non-agency markets and use-cases, Asteroom provides additional inspection elements like damage identification & measurement, equipment and appliance identification, definition of materials and finishes, verification of utilities, and other custom requirements.

Pre-populated UAD 3.6 URAR Hybrid Appraisal

Asteroom has introduced a series of features to enable appraisers to complete UAD 3.6 hybrid appraisals faster and with more confidence.

• The high definition floor-to-ceiling 3D walkthrough enables appraisers to virtually inspect the subject property and site. Any inconsistencies or clarifications can be identified by the appraiser.
• Lenders, underwriters, investors and third-party review firms also use 3D walkthroughs to reconcile report discrepancies and disputes, and resolve repurchase requests associated with collateral.
• Pre-population of the UAD 3.6 URAR appraisal directly from UPD is now available, significantly reducing the time to complete appraisals
• For Cotality/a la mode TOTAL users, Asteroom provides the Zap file to make the transition from UPD to URAR seamless. Other appraisal report writing integrations are in-the-works.

Rather than requiring appraisers to manually re-enter inspection data, Asteroom pre-populates property characteristics, room-level details, condition observations, floor plan data, and photos and exhibits. This reduces the time to complete an appraisal by 2-3 hours, and improves consistency between the inspection dataset and the final URAR appraisal report.

UAD 3.6 Hybrid Appraisal Vendor Checklist

Asteroom is uniquely positioned to support UAD 3.6 Hybrid Appraisal. By providing a full 3D scan of the property, Asteroom UPD reports helps appraisers, underwriters, and secondary marketers fully assess the collateral. 

Borrowers also get a 3D virtual tour documenting every aspect of their property.

As UAD 3.6 adoption expands, hybrid appraisal providers are increasingly being evaluated on the quality, completeness, and usability of the property dataset — not simply the ability to collect photos. Asteroom is positioned around creating a structured digital property record designed to support both current hybrid appraisal workflows and future collateral data requirements.
