The Property Feature Field Key translates the coded property fields returned by the v3 API into readable descriptions. Codes are sourced from county assessor and recorder records and normalized nationally.
Sale qualification and price-derivation codes already use Realie’s own code system (TQ#### / PD####, documented below). Building and characteristic code values migrate to prefixed Realie codes in an upcoming data release, announced in the changelog with a complete mapping before it ships.
Same numeric scheme as the v2 API. A small number of v2-era codes are retired by the current source and re-coded to more specific successors (e.g. generic exempt-vacant codes now appear as owner-specific exempt codes); see the migration guide.
Roof material (asphalt, tile, metal, …).
Roof shape (gable, hip, mansard, …).
Deed/instrument type on sale and transfer records. A small share of records (<1%) carry the document type as self-describing full text (e.g. WARRANTY DEED) or a rare source code not yet in this table; unmapped codes fold into named entries in an upcoming release.
Numeric buyer-relationship codes on sale records.
Numeric vesting codes on sale records.
Sale-qualification codes in the Realie code system (TQ####). One vocabulary across all sale events; a null means the source recorded no qualification signal for that sale.
How the sale price figure was obtained (PD#### — stated on the document, computed from transfer tax, from an affidavit, …). Currently included in bulk data exports; API response exposure is planned in an upcoming release.
Foreclosure record stage.

Free-text fields

zoningCode, stateLandUseCode, and countyLandUseCode are county-issued free text, not members of a national code system. No global decode table exists or should be inferred; values are meaningful within their county.

foundationType

foundationType passes through source values without a national table and is sparsely populated; treat it as descriptive text.
