Notes

Idaho tax-deed county. After statutory delinquency, Ada County Treasurer issues tax deeds to the county; public auction of tax-deeded property is held within 14 months of tax deed issuance. Auctions have been online (historically Bid4Assets); 2022 tax-deed auction date listed TBD on treasurer page with pending list PDF — inventory is sparse compared with larger states. Minimum bid typically equals total delinquent taxes, late charges, interest, and costs. Redemption ends when tax deed issues / sale rules apply — verify current Idaho Code path per parcel.

Title risk

Liens that survive the sale

Idaho tax deed is designed to convey free of most prior encumbrances except subsequent property taxes and certain special assessments — federal liens and title defects still require independent analysis. Sold as-is.

Quiet title

Title insurers commonly require quiet title or extended seasoning after tax-deed purchase before insuring marketable title for resale/refinance.
