Data sources

Review the datasets, provenance, and freshness rules that support DealGrade analysis.

Data principles

How we keep every analysis trustworthy and transparent.

Provenance first

Always keep source and freshness visible.

Proxy honesty

Do not present area signals as property-level certainty.

Coverage transparency

Be explicit about regional gaps and sample depth.

Model provenance

DealGrade combines official and licensed datasets with deterministic scoring rules so historical runs remain reproducible.

Model version: n/a

Snapshot ref: n/a

As-of date: n/a

DealGrade is a risk-assessment and decision-support tool. Area-level signals are proxies and should be stress tested alongside independent due diligence.
