Notes

Suffolk is NOT part of the suspended NYC lien program. County runs online surplus / tax-delinquent real property auctions (in rem / surplus inventory) via Realauction (suffolk.ny.realforeclose.com). 2025 sale held Dec 10–11, 2025; mandatory registration windows posted per cycle. Separate Suffolk County Landbank handles some tax-delinquent redevelopment RFPs (not the public auction). Confirm each year’s list on the Real Estate / GIS dashboard.

Realauction — Suffolk County Real Property Auction ↗

Deposit rules

Mandatory pre-registration on Realauction with deposit/terms posted per auction brochure (see SuffolkTerms.pdf / Auction Terms on the Realauction site). Deadlines are hard — 2025 registration closed Dec 3 for Dec 10–11 sale.

Title risk

Liens that survive the sale

In-rem / surplus deed quality depends on the foreclosure judgment and sale type. Federal tax liens can survive; municipal water/sewer and code liens need parcel-level search. Review auction terms carefully.

Quiet title

In-rem judgments often support marketable title, but insurers may still require quiet title or extended review depending on notice history and parcel type.

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.
