# Hybrid Appraisal Property Data Collection Network

Posted by [Eric Tsai](https://blog.asteroom.com/author/eric-tsai) on September 17, 2026

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](https://www.asteroom.com/en/realtors)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

This creates a more complete property dataset for the appraiser while improving transparency for lenders, underwriters, QC teams, and secondary marketers.

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.

| **Capability** | **Asteroom** | **UPD Competitors** |
| --- | --- | --- |
| Proprietary 3D Scan | ✓ | - |
| ANSI Floor Plans | ✓ | Partial |
| Real-Time QC at Property | ✓ | - |
| Overnight QC Review | ✓ | Limited |
| Floor Plan QC | ✓ | Limited |
| Virtual Tour for Marketing | ✓ | - |
| URAR Pre-filled with UPD report data | ✓ | - |
| Structured Property Dataset | ✓ | Partial |

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.
