Mount Vernon sells its tax liens in sessions, under Section 162 of the City Municipal Code, conducted by the Office of the Comptroller. The December 2025 notice is for Session #3, covering arrears for 2020 and 2021 with a lien date of December 18, 2024: the city works through its delinquency in successive session lists rather than one annual sale. Separately, on January 27, 2025 the city authorized in rem foreclosure procedures by ordinance under Chapter 783 of the Laws of New York, a second enforcement track; no in rem auction under it is documented in the sources read.

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 City of Mount Vernon, searchable by address, owner, or county, including parcels that never reach a sale list.

Preregistration through the city's Viewpoint Cloud portal (category 1082) is highly recommended, per the December 2025 notice. A hard registration deadline is not published in the notices read.
The December 2025 notice publishes the buyer's payment terms directly. Post sale redemption terms are not published in the notices read and are not stated:
| Down payment | 10 percent of the lien amount, at purchase (December 2025 notice) |
| Balance due | Within 15 days, by certified or official bank check payable to the City of Mt. Vernon |
| Buyer premium | Not published: none is stated in the notices read |
| Deed type | Not applicable at the lien stage: this is a lien sale. Certificate mechanics are not published in the notices read |
Mount Vernon rewards session tracking: the lists arrive in numbered sessions covering specific arrears years, so a buyer's research is the session list itself, worked when the notice posts. One caution: the June 2025 notice's deposit line prints unclearly, and the clean 10 percent figure on this page is the December 2025 notice's. Read the current session's notice directly before relying on any number.
