lookup_parcel
Look up cached parcel/county-tax-assessor data by APN+county or property address.
Look up cached parcel/county-tax-assessor data by APN+county or property address. Returns assessed value, annual property tax, county, owner name (sanitized for AI use). Cache-only read — does not trigger a paid vendor lookup. Use BEFORE generating a net sheet to enrich seller proceeds estimates with verified tax basis. Returns null if the property has not been previously cached.
