The PropVault Score.
A standardized integrity rating for a documented property. Think of it as a credit rating for a home’s record — derived from the evidence in the Vault, not from opinion or appraisal.
Four components, one composite.
Every Vault’s Score is a weighted composite of four independent measures. Each is scored 0–100 and rolled up into a single number from 0 to 100, then mapped to a letter grade.
How much of the expected record is documented — across title, permits, inspections, warranties, and attestations. A well-maintained home has something to say in every category.
Who vouched for the record. Independent auditors and municipal records weigh more heavily than an owner's own attestations. Third-party verification compounds.
How fresh the record is. A two-year half-life means entries lose weight continuously; recency is the only component that decays without new activity.
How much of the home's critical systems are currently under active warranty — roof, HVAC, appliances, structural. Rewards proactive ownership.
Seven letter grades.
Composites map to letter grades on a fixed scale. The bands are intentionally conservative — most homes start in the middle and climb as evidence accumulates.
| Grade | Composite | Interpretation |
|---|---|---|
| AAA | 90+ | Exceptional. Deep documentation, third-party verified, current. |
| AA | 80–89 | Strong. Comprehensive record with independent verification. |
| A | 70–79 | Good. Substantial evidence with some verification. |
| BBB | 60–69 | Adequate. Core documents present, owner-attested. |
| BB | 50–59 | Light. Material gaps in coverage or verification. |
| B | 40–49 | Sparse. Record is thin; rely heavily on inspection. |
| C | 0–39 | Minimal. Little documented evidence available. |
Scores aren’t static.
Recency decays continuously on a two-year half-life. A Vault that was a 90 last year with no new entries is not a 90 today. The other three components stay frozen at their last audit — they are point-in-time facts — but the Score as a whole will drift down without ongoing maintenance. Add entries, re-verify, and the Score climbs back.
The Score is recomputed automatically when the ledger changes: new entries, redactions, or grants. Owners can also trigger a manual recompute from the vault detail page.
What the Score is not.
The PropVault Score is a documentation integrity metric. It measures the completeness, verification, freshness, and coverage of the record in the Vault. It does not represent property value, market condition, or professional appraisal. It does not replace title, inspection, or appraisal reports. It does not opine on whether a property is a good investment.
