Background

ACS PUMS contains owner-occupied property value in VALP. The existing us-data ACS flow already imputes rent and real_estate_taxes into CPS via QRF, but it does not carry a property value signal. Property tax modeling needs this as market/property value, not assessed value.

Proposed work

• Add VALP to the raw ACS household columns.
• Generate person-level primary_residence_value in acs_2022.h5 from household VALP.
• Set positive values only for owner household heads, with zero values for renters, non-owners, and non-head people.
• Add primary_residence_value to both ACS-to-CPS QRF paths:
  • legacy datasets/cps/cps.py::add_rent
  • current calibration/source_impute.py::_impute_acs
• Ensure pre_subsidy_rent behavior remains unchanged.
• Update unit tests, tiny fixtures, and Stage 1 validators.

Dependencies

Depends on PolicyEngine/policyengine-us#8351 so policyengine-us-data can export primary_residence_value as a recognized input variable.

Acceptance criteria

• Built ACS artifact includes primary_residence_value.
• CPS/source-imputed outputs include person-level primary_residence_value.
• Renters, non-owners, and non-head people receive zero values.
• No code labels raw ACS VALP as assessed value.
