BuildingType
MULTIFAMILY (no underscore) is accepted as an input alias for MULTI_FAMILY on
the buildingType and excludeBuildingType filters. Responses always return the
canonical spelling MULTI_FAMILY.ListingStatus
Borough currently emits
ACTIVE and OFF_MARKET only. IN_CONTRACT is a
reserved value that the data feed does not yet surface, so listings transition

IN_CONTRACT as a forward-compatible value: match on it if present, but do not
rely on it for in-contract detection today.SaleType
