A woman owed roughly two thousand dollars in property taxes and lost a home worth two hundred thousand. Until 2023, in a number of states, the government could keep the entire difference. This article explains how property tax sales work, why they exist, and how a small delinquency turns into the loss of everything. It covers the two systems — tax lien states and tax deed states — and why the difference determines how much time an owner has. It explains the redemption right, what it costs, and the deadlines that end it. It covers the constitutional decision that ended the practice of keeping surplus proceeds, and what owners can now claim. It closes with what actually saves a house, in the order that matters.
