How to pull deed and sales history programmatically
A programmatic deed and sale workflow must separate assessor-reported sale history from a legal chain of title. Quoin can return DC sale and deed context with source evidence, but it does not issue a title conclusion.
Start freeResolve before retrieving history
Use a DC SSL or address with resolve_property. Confirm that the result represents the intended tax account before requesting transactions. Related accounts can exist at one physical address.
For a bounded transaction view, use get_ownership_and_sale or get_latest_sale_and_deed. The current product catalog also provides get_complete_property_record when the workflow needs a broader account record.
Know what the source represents
The official Tax System Property Sales CAMA export is assessor sale history. It is not a complete Recorder of Deeds index or chain of title. The latest deed fields in the property tax extract are assessor-reported context.
The current Quoin release does not provide a complete deed-image archive, lien-priority conclusion, or title report. Use the Recorder and qualified title review when the decision requires those records.
Verified DC source example
The product evidence set includes the DC account at 1801 K Street NW, SSL 0107-0075. Its official CAMA example identifies source record 473583123 and a reported sale dated January 14, 2015 for $445,000,000.
The human verification route is the official DC Open Data Tax System Property Sales CAMA page. Search by the SSL or address, then match the source record ID.
Preserve unusual source values
Keep source sale codes, zero-price transfers, sentinel dates, and quality flags. Do not silently convert an unusual record into a conventional sale.
Record the source release date and verification inputs with the result. A reviewer can then distinguish a historical frozen record from a newer live portal entry.
