Notes

Ohio hybrid county — separate tracks. (1) Mortgage/judicial sheriff sales run online via RealAuction Official Public Sheriff's Sale Website (darke.sheriffsaleauction.ohio.gov), often Friday 10:00 a.m. online sales. (2) Treasurer's Tax Sales for delinquent taxes are a distinct in-person process (historically at Commissioners building with day-of deposit) — do not assume RealAuction covers the tax track. Confirm current Treasurer tax-sale calendar and deposit with Darke County offices before treating either path as the only product. Greenville / west-central OH agricultural and manufacturing market near I-70.

Auction logistics

Format

Hybrid: online RealAuction sheriff (mortgage/judicial) sales + in-person Treasurer tax sales

Frequency

Sheriff/mortgage sales: as scheduled (often Fridays online). Treasurer tax sales: as noticed until further notice — confirm current calendar

Platform

Darke County Sheriff Sales (RealAuction) / separate Treasurer tax sale ↗

Deposit rules

RealAuction judicial/sheriff sales: register on platform; statutory deposit tiers and wire/ACH deadlines apply (confirm parcel list and FAQ). Treasurer tax sales: historically ~15% deposit due day-of in person — confirm current Treasurer rules separately. Do not mix the two funding tracks.

Title risk

Liens that survive the sale

Certificate path vs. forfeited-land path vs. mortgage sheriff sale differ. After a proper tax deed/forfeiture or confirmed judicial sale, most junior private liens are cut off; federal liens can survive. Read each case caption carefully.

Quiet title

Forfeited land and foreclosure pathways often clear title judicially; certificate holders must complete statutory foreclosure. Quiet title still common for resale.
