Chautauqua County tax sale, 2026 season

Verified

Chautauqua County (county seat Mayville) sells its tax foreclosed real estate online only through Auctions International, on the ChautCoAuction.com sale site. The 2026 auction opened Friday, July 17, 2026 and closed in two parts: Jamestown and Dunkirk lots on Thursday, July 30, 2026, and the rest of the county on Friday, July 31, 2026. The gate was the registration packet, due back to the auctioneer by Tuesday, July 28, 2026 at 4:00 PM, while bidding was already open.

The next auction has not been announced in the county or auctioneer sources checked, and this county does not hold a fixed month: the 2025 cycle ran its closings in September. What is verified below is the 2026 cycle as it actually ran, plus the premium the 2026 catalog published. The deposit and balance rules for 2026 sat in a full terms booklet the catalog references; where that booklet was not published in the sources read, this page says so instead of borrowing last year's numbers.

Research Chautauqua 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 Chautauqua County, searchable by address, owner, or county, including parcels that never reach a sale list.

How New York tax foreclosure works

Unpaid taxes become a lien on the property, and the county enforces that lien in court under Real Property Tax Law Article 11, the in rem foreclosure process.
The owner gets a redemption period, two years from the lien date by default, longer where a local law extends it for homes or farms. Paying everything owed during that window ends the case.
When the period expires, the court can award the property to the county. The former owner's right to redeem is over at that point; there is no post-sale redemption period on a New York tax deed.
The county then sells at public auction, which is the sale this page tracks. Deeds are usually quitclaim, bids can require county legislature approval, and any surplus over the taxes and charges is handled under RPTL sections 1195 to 1197 for the former owner and lienholders.

How registration works

Registration ran online on the auction site. The online bidder registration packet had to be completed and returned by Tuesday, July 28, 2026 at 4:00 PM, two days before the first closing day, with bidding already open since July 17.

Read the full terms booklet attached to the next auction's catalog before you register: it carries the deposit schedule and the balance deadline for that cycle, and those figures are set per auction, not by a standing county page.

Terms: what a bid actually costs

The 2026 catalog published the buyer premium. The deposit schedule and the balance deadline for 2026 were in the auction's full terms booklet, which was not among the sources retrievable on the check date, so they are stated as unpublished here rather than copied from the 2025 cycle.

Buyer premium	8.77 percent of the bid when paid by credit card (Visa, Mastercard, Discover); 6 percent when paid by cash or certified funds. Published in the 2026 auction catalog.
Deposit or down payment	Not published in the sources checked. The full terms booklet for the cycle governs.
Balance due	Not published in the sources checked.
Deed type	Quitclaim deed in the county's standard auction terms; the County Legislature acted on the 2026 auction deeds by resolution on September 23, 2026 (Resolution 237-26), after the sale.

Before you bid

Bids in this county are not the last word: the County Legislature approved the 2026 auction deeds by resolution weeks after the closings, and the county can act on individual parcels inside that process. Verify before you go: the next cycle is unannounced, and parcels get pulled when owners settle. Read the official catalog and terms for the next auction before you register.
