Registration fee $175 + minimum deposit $5,000 + budget submission. Registration/deposit deadline for 2027 sale: Feb 5, 2027. Balance due from lien purchases by Mar 18, 2027. Taxes must be paid by Feb 10, 2027 to keep a parcel off the sale list.

Title risk

Liens that survive the sale

Buyer receives a tax lien certificate, not the property. Owner redemption (with statutory interest) extinguishes the certificate. Surviving-lien analysis becomes critical only if/when foreclosure of the right of redemption is pursued. Federal liens and some municipal charges can survive that process.

Quiet title

To obtain title, certificate holder must complete statutory foreclosure of the right of redemption — that judicial step is the core title-clearing process; insurers may still require additional quiet-title comfort.

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.
