Official sale records parsed from cached Bulk PSI ZIP files with parser guardrails for token sales, non-house zoning, and low-value strata component records

RENT POSTURE
Rent is using a state market dataset when available.

Use current rent as a starting signal, not as a fixed underwriting truth.

SERVICE POSTURE
