How we estimate home condition

What the 1000-point score represents

The public score is a current-risk estimate on a 1000-point scale. Higher values mean stronger evidence that a home deserves closer condition review; they do not prove a defect exists today.

The score is designed for prioritizing due diligence, inspection questions, repair planning, and collateral review. It is not an appraisal, inspection report, engineering opinion, insurance review, lender review, or statement of fact about current property condition.

Condition evidence types

• Verified direct evidence: property-specific historical condition evidence can influence the condition component, but it is adjusted for evidence age, system persistence, and public evidence caps.
• Proximity estimate: when no direct condition signal is connected, nearby inspected-home patterns can estimate likely risk areas. This does not verify that the same issues exist at the subject home.
• Area estimate: when close-proximity evidence is limited, broader area patterns can provide a weaker signal with tighter caps.
• Missing condition signal: when direct, nearby, and area evidence are unavailable, the score relies only on connected public-data components.

Public data inputs

• County assessor parcel and CAMA records, including year built, living area, parcel facts, and property class where available
• Public permit history where available, including repair, replacement, and renovation context
• Flood and water-risk context from connected public mapping data
• Code-enforcement and neighborhood-condition context where available
• Address normalization and geocoding used to connect records to the correct location

Evidence caps, recency, and confidence

The model reserves the 900-1000 range for recent, property-specific, highly corroborated risk. Older signals, indirect signals, and lower-persistence systems are reduced before the public score is shown.

Direct historical evidence, proximity evidence, area evidence, public records, and missing inputs do not carry the same confidence. The page separates score level from data confidence so users can see both the estimated risk and how much supporting data is connected.

Privacy and limits

Private source documents and customer reports are not shown. Public pages use score components, evidence labels, confidence, and privacy-safe condition signals rather than exposing private documents.

Always confirm property condition with a qualified home inspector before making an offer, lending, insurance, purchase, sale, or major repair decision.
