What each signal means
Absentee owners
The tax bill goes somewhere other than the property. A landlord or an heir.
Usually from: Assessor: mailing address differs from property. Weight in Deal Radar's score: 6, doesn't fade.
Long-time owners
Owned for decades. Lots of equity, and often a life change coming.
Usually from: Last sale date on the deed. Weight in Deal Radar's score: 6, doesn't fade.
Permits
Work is being done: repairs, a remodel or a teardown, sometimes before a sale. A weak signal on its own.
Usually from: Building permits (pre-sale repairs). Weight in Deal Radar's score: 4, halving every 120 days.

What isn't here
- Owner names, mailing addresses and phone numbers. Public pages show counts only; phones never come from these feeds.
- Probate and divorce filings. They sit with the courts and several states restrict them; inside Parcel they come in by upload.
- Records a city or county doesn't publish as open data. If yours has a feed we've missed, tell us and we'll check it.
