How California tax sales work
California has no investor lien: the county (or another government office) sells the property itself, and the buyer generally takes title once the sale is final, subject to the state's rules on confirmation and any remaining redemption rights.
How the auction is won: Auction, minimum = redemption amount. Redemption period: Until the business day before the sale.
Sources: Cal. Rev. & Tax. Code §3691 · §3707
