Title risk

Liens that survive the sale

In-rem foreclosure extinguishes pre-existing tax liens and is intended to clear many private liens; federal tax liens can survive. Buyers often assume current school/village taxes. Water/sewer and code issues need separate analysis.

Quiet title

In-rem judgments often support clearer title; local practice may still recommend quiet title or seasoning for residential resale insurance, especially Fort Drum-area military housing stock.

New York has no statewide level of assessment. Each of 1,200+ assessing units sets its own, and ORPTS publishes an equalization rate and residential assessment ratio per unit each year. 1.0 is used here as a deliberate floor — see the derived-ARV note — not as a claim that New York assesses at full value.
