What each signal means
Code violations
The city cited the property for its condition. Landlords tired of repairs and owners who can't afford them both show up here.
Usually from: City code enforcement. Weight in Deal Radar's score: 14, halving every 180 days.
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.
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.
Out-of-state owners
The owner lives in another state, which makes the property harder to manage.
Usually from: Assessor: owner mails out of state. Weight in Deal Radar's score: 9, doesn't fade.
