The short answer
None after the county's annual sale. Before that, the owner may satisfy the tax lien up to the October 1 foreclosure date, and after the county takes the deed a statutory right of repurchase runs for as long as the tax title remains in the county.
How the clock works
There are two distinct windows and neither is a redemption against a private buyer. Up to October 1, paying the amount in the foreclosure notice stops the process. After the tax deed vests in the county, the former owner, the former owner's executor or administrator, or a parent, spouse or child of the former owner may repurchase the property so long as the county still holds tax title, for cash or on a contract for deed. A city holding a delinquent special assessment has a prior right to buy at the appraised value, exercisable within 30 days of the auditor's notice. Once the county sells at the annual auction, the purchaser's deed is not subject to any of this.
Who can redeem
Before foreclosure, the owner or any party paying the amount stated in the notice. After the county's tax deed, only the former owner, the former owner's executor or administrator, or a parent, spouse or child of the former owner, and only while the county still holds title.
How your interest accrues
Not applicable to investors. Penalties and interest under 57-20-01 accrue to the county on the unpaid tax, never to a private certificate holder, because no certificate is issued.
What happens when it ends
Property for which two or more years have passed since the tax became due. The county auditor gives notice of foreclosure of the tax lien on or before June 1, and the lien is foreclosed on October 1 after service. The auditor then issues a tax deed passing the property in fee to the county, free of encumbrances except certified or later special assessment installments and the homestead credit lien named in the section.
A redeemed certificate, plus your accrued interest, is what makes the wait profitable; see how redemption periods work across states. An unredeemed certificate is instead your path to the property through a tax deed sale, which still does not convey marketable title on its own, so budget for a quiet title action.
