Notes

New York In Rem tax foreclosure county. Rensselaer County Bureau of Finance / Delinquent Tax Unit enforces multi-year delinquencies (Article 11 RPTL); after foreclosure, surplus parcels auction online via Collar City Auctions. Documented 2025 county auction: bidding from Nov 21, 2025 with closes Dec 18, 2025 and contract signing early January 2026. City of Rensselaer may run separate municipal tax auctions on the same platform — do not confuse city-only sales with county-wide inventory. Delinquent Tax Unit: 518-270-2754 / 518-270-2755.

Title risk

Liens that survive the sale

Quiet title

Often still used for marketable/insurable title after county deed, depending on insurer and resale plans.

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.
