What the process does
long time homeowners list is the search intent this page answers. Watchdog uses checked public property records and clear calculated numbers to narrow a research set before a professional makes a decision.
Worked New Jersey example
Where deed and sale-year history is supported, sort a farm by years since last recorded sale and then verify each record before outreach.
What it does not tell you
A long holding period does not imply age, equity, motivation, family status or likelihood to sell.
Method
Start with a defined property geography or known-client list, attach only supported public-record fields, keep source and observation dates with the data, and separate observed facts from Watchdog-calculated screening red flags.
