Tax lien states
In a tax lien state, the county sells a tax lien certificate against a delinquent property instead of the property itself. You pay the back taxes, and the owner repays you with interest during a set redemption period. If they never redeem, you can eventually move to take the property. It is the yield play, as opposed to the property play of a tax deed state.
States that sell tax liens
We are mapping states one at a time with statute-cited, county-level data. Live states link through to full rules and every county; others are on the roadmap. Hybrid states (like Florida) sell both liens and deeds, so they appear here and on the deed list.
