The Tax-Sale Playbook

A debt of a few thousand dollars — sometimes a few hundred in unpaid taxes or sewer charges — can put a house worth far more at risk. Owners without a mortgage are most exposed because there's no servicer paying taxes from escrow and monitoring the account. But the law builds in protections: redemption periods, surplus funds rights, and notice requirements. Those protections only help owners who know about them and act before the windows close.

How tax sales work

When property taxes go unpaid, the county eventually auctions either the tax debt (a tax-lien certificate) or the property itself (a tax-deed sale). A tax-lien purchaser doesn't own your house — they own the right to collect your overdue taxes with interest, and the right to take the deed if you don't pay (redeem) within the redemption period. That window is the single most important date in a tax-delinquency situation.

Your surplus-funds rights

Under the 2023 Supreme Court decision Tyler v. Hennepin County, equity beyond your tax debt and lawful costs should be returned to you — not kept by the government or the buyer. But the protection is still settling across states: how to claim a surplus and the deadlines vary widely and can be easy to miss. Act fast and talk to an attorney about your surplus rights.
