Verified property data. The backbone of modern appraisal.
A trained, independent data collector visits the property — photographing, measuring, and documenting condition — so the licensed appraiser has the verified data needed for a reliable desktop or hybrid valuation.
The full picture
Property Data Collection (PDC) involves a trained, non-appraiser data collector visiting a subject property to gather structured information: interior and exterior photos, floor plan sketches, room measurements, and property condition observations. The resulting Property Data Report (PDR) feeds into desktop appraisals, hybrid (bifurcated) appraisals, and GSE value acceptance pathways where verified property data is required by Fannie Mae or Freddie Mac. Home Base manages PDC assignments through AppraisalDesk with the same quality controls as full appraisal orders — including collector vetting, data review, and report management.
Common use cases
- Desktop appraisals (GSE 1004 Desktop) where the appraiser does not inspect the property in person
- Hybrid/bifurcated appraisals where the data collection and appraisal steps are separated
- Fannie Mae or Freddie Mac value acceptance pathways that require a PDR to support the loan
- Lenders building a UAD 3.6-ready workflow requiring expanded property data and photo documentation
- Transactions where a full interior inspection by a licensed appraiser is unnecessary, but AVM-only data is insufficient
- Portfolio due diligence requiring documented property condition across multiple assets
Local expertise. Technology that runs lean. People who pick up the phone.
Trained, Vetted Collectors
Every data collector in our network is trained in GSE-compliant data standards — property measurement, condition rating, and photo documentation. We vet and credential collectors the same way we vet appraisers.
Integrated with Desktop & Hybrid Workflows
PDC isn't a standalone product — it's the foundation of the modernization stack. Home Base delivers PDC alongside desktop appraisals and hybrid valuations as a coordinated workflow, not disconnected parts.
UAD 3.6 Ready
The expanded photo and data requirements of UAD 3.6 (rolling out November 2026 for GSE loans) are built into our PDC workflow. Collectors are trained to capture the documentation the new form requires — so your pipeline is ready ahead of the deadline.
Does this support Fannie Mae Value Acceptance?
Yes — our PDR workflow is designed to satisfy the property data requirements for Value Acceptance + Property Data. Learn how the full modernization suite fits together.
