A tax deed has to ripen first
The purchaser at a Georgia tax sale takes a defeasible deed, not clear title. To cut off redemption they must wait out the redemption period and then serve the barment notice required by O.C.G.A. §§ 48-4-45 and 48-4-46 on the defendant in fi. fa., the occupant, and everyone holding a recorded interest. If they never do, § 48-4-48 lets the title ripen by prescription four years after the deed is recorded. Meanwhile the cost of redeeming grows: § 48-4-42 adds ten percent for each year or fraction after the first, on top of the taxes and the initial premium.
