Notes

Ohio hybrid county — Union County (Marysville / Columbus northwest exurb; Honda manufacturing corridor). Mortgage-style sheriff real-estate sales moved online to RealAuction (union.sheriffsaleauction.ohio.gov) Wednesdays 9:00 AM ET when inventory posts; proxy bids open at least 7 days prior. IMPORTANT: Tax Sales, Tax Lien Certificate Sales, and Probate Sales continue IN-PERSON at Union County Veterans Memorial Auditorium, 233 West 6th St, Marysville, until further notice — separate from online RealAuction calendar. County posts PDF sale lists (including County Tax Sale updates). Strong Honda-related employment drives housing demand; confirm which track each parcel is on before registering deposits.

Title risk

Liens that survive the sale

Certificate path vs. tax-forfeiture/sheriff path differ. After proper tax deed/forfeiture or completed judicial sale, most junior private liens are cut off; federal liens can survive. Identify sale type on the PDF list.

Quiet title

Forfeited-land and foreclosure pathways often clear title judicially; certificate holders must complete statutory foreclosure. Quiet title still common for resale in the Columbus exurb market.
