environment_characteristics

Environmental factors and natural-disaster exposure around the property.

Environmental factors, natural disaster risks, and surroundings that affect property desirability and safety.

The question it answers

What is this house, physically?

The feature vector, taken from the source of record rather than from a listing agent. Assessor and parcel records are authoritative; listing fields are agent-entered, inconsistent between markets, and absent entirely for a property that was never listed.

Why it matters

Environmental exposure is priced by insurers before it is priced by buyers, so it reaches a valuation through carrying cost as much as through desirability.

In practice

The class covers surroundings as well as hazards, which is deliberate: proximity to industrial use, noise and air quality are recorded facts about a location in some jurisdictions and are otherwise only visible from a site visit.
