Verify property ownership from public records data

Steps

1. Resolve the subject property to a canonical parcel identifier using an address-matching API such as Regrid typeahead or ATTOM address search
2. Request owner-of-record data from the parcel record returned by Regrid or ATTOM; fields typically include owner name(s), mailing address, deed recording date, and sale price
3. For chain-of-title verification, use ATTOM's /allevents or /saleshistory endpoint to retrieve the history of recorded deeds and conveyances on the parcel
4. Cross-reference the owner name and mailing address against the county assessor or recorder's public database using Bridge Interactive's public records dataset or PropMix where available
5. Flag discrepancies between the data provider's owner record and any information the seller has provided; escalate to a title company for formal title search if ownership is unclear
6. Persist the ownership snapshot with a timestamp so that any ownership change detected on a subsequent check can be flagged as a title cloud
