Last checked Tue, Oct 27, 2026

Information only, not investment or legal advice. Sale dates, terms and deadlines change; always confirm with the county before you register or bid.

Upcoming sales

No confirmed 2026 date. The Treasurer's tax sale page says "The delinquent tax sale will be held on Monday, October 27, 2025" but also says registration forms for "this year's sale" were due "by October 9, 2026", so the page is partly out of date. The Treasurer's main page lists a last day to pay 2025 taxes of Oct. 23, 2026. Contact the Collector's Office for the 2026 sale date.
