Assessor sale history

Assessor sale history is transaction information carried in an assessor or tax-system dataset. It can support property research, but it is not a complete deed index or chain of title.

DC source

The official Tax System Property Sales CAMA export provides DC assessor sale records. Quoin preserves source dates, source record identifiers, sale codes, sentinel dates, and zero-price transfers instead of silently rewriting them.
