Alaska
Alaska is unlike every other state on this list — it's the only one with no state-level property tax at all. Tax sales exist only where a borough or independent city chooses to levy the tax, which covers roughly 15–24 of Alaska's local jurisdictions; the rest of the state, including most of the sprawling 'unorganized borough,' has no property tax and no tax sale process whatsoever. Where it does exist, delinquent property forecloses to the municipality first — about a year past judgment, on top of the delinquency period that preceded it, the municipality takes a deed, then resells it later at its own public auction, cash to the highest bidder, on its own schedule. There's no annual statewide calendar and no investor-facing interest rate; you're researching each borough's ordinance and auction history separately, and some smaller boroughs go years without a sale.
