Nassau County tax lien sale, February 2027

Verified

Nassau County (county seat Mineola) is a lien county: the County Treasurer sells tax liens at public auction every February under the Nassau County Administrative Code, and buyers bid the interest rate down, lowest rate wins, capped at 10 percent of the purchase price for each six month period through the first 24 months. You are buying a lien and a certificate, not a deed and not the property.

The next sale is dated and official: the 2027 sale of 2026 tax liens runs Tuesday, February 16, 2027, online. Bidding commences Friday, January 22, 2027, and the gate is earlier: registration, the $5,000 minimum deposit, and your submitted budget are all due by Friday, February 5, 2027. Claims that Nassau sells its liens only to institutions in bulk are contradicted by the county's own 2027 sale page, which sets registration terms for individual bidders.

Research Nassau County parcels before you bid

A sale list gives you the parcels, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across Nassau County, searchable by address, owner, or county, including parcels that never reach a sale list.

How a New York tax lien sale works in Nassau County

The county sells the lien, not the land. A winning bid buys the county's tax lien on the parcel and a certificate of sale. Title does not move.
Bidding is on the interest rate. The rate the owner must pay is set by the bid, down from the statutory maximum of 10 percent of the purchase price for each six month period through month 24. The county keeps a Differential Interest Lien for the slice of the maximum rate above your bid rate; that slice is paid separately on a deed application or a surrender.
The owner can redeem at any time before the Treasurer issues a tax deed or a foreclosure action is commenced, and neither can happen before 24 months after the sale at the earliest. On redemption, the Treasurer pays you your purchase money plus interest at your bid rate.
If the owner never redeems, the path to a deed runs through the Treasurer's tax deed application process or a court foreclosure by the lien holder, on the Administrative Code's schedule and notice rules, not at the auction.

How registration works

Register on the county's auction site for the specific sale. For the 2027 sale, three things are due by Friday, February 5, 2027: the registration itself, the $5,000 minimum deposit, and a submitted budget for what you intend to spend. One conflict in the county's own documents is worth flagging rather than smoothing over: the Treasurer's Notice to Tax Lien Purchasers, citing Ordinance No. 175-2015, describes the registration fee as $175.00 per day per bidder, while the 2027 sale page phrases it as a flat $175. Budget for the fee, and confirm the reading with the Treasurer before the deadline.

Terms: what a bid actually costs

The money layer, from the county's published terms of sale and the Treasurer's purchaser notice. Time is of the essence throughout: the balance deadline has no grace mechanism.

Registration money	$5,000 minimum deposit plus the $175 registration fee (see the wording conflict flagged above), due by February 5, 2027 for the 2027 sale. Unapplied deposit funds are returned.
Down payment at the sale	10 percent of the total amount from which the liens were sold, due by the end of the day on the sale day.
Balance due	The remaining 90 percent within 30 days of the sale, by 3:00 PM on Thursday, March 18, 2027 for the 2027 sale. The Treasurer notifies purchasers by email within 10 days of the due date. Miss it and the lien is automatically lost and the total down payment is forfeited. No extensions.
Certificate fee	A Tax Certificate Issue Fee of $20.00 per lien purchased, due on payment of the 90 percent balance.
Buyer premium	None published. This is a rate-bid lien sale, not a premium sale.
What you receive	A tax lien certificate, not a deed. Liens sell subject to superior tax liens of sovereignties and other municipalities, to claims of record the county holds, and to possible bankruptcy stays. The Treasurer may withdraw any parcel at any time without notice.

Before you bid

Underwrite the wait, not just the rate: your money is committed for at least 24 months before any deed route opens, and interest accrues at your bid rate in six month steps, with months 25 to 36 in a hardship extension priced at 5 percent per six month period. Once a lien is sold, a delinquent balance on it is payable only by bank cashier's check or cash, not online. Verify before you go: the Treasurer can pull parcels at any time, and the official sale page is the final word.
