03Why it matters
Once a certificate is sold, a clock starts: after the redemption period the holder can ask for a deed or a foreclosure.
04Where it shows up in public records
Tax-lien and certificate sales are run by the treasurer or tax collector, and the list of sold certificates is public in many states.
05How to find tax lien in 3 steps
- Step 1, find the record: tax-lien and certificate sales are run by the treasurer or tax collector, and the list of sold certificates is public in many states.
- Step 2, match it to the property: join the record to the parcel by its parcel number and the owner's name and address, so you know which house it belongs to.
- Step 3, add a second reason: stack tax lien with another list to see which owners have more than one reason to sell. LeadCounty does steps 1 and 2 for every property each week.
06How we count it
LeadCounty counts tax lien from each county's own records and shows the number for every county in the table above, refreshed weekly. A county that does not publish the record shows no count rather than a guess.
07How to use it
- Reach out early in the redemption period, while the owner still has time and choices.
08Best stacks with tax lien
One list gives you a reason; two or three lists together give you owners with several reasons at once. The stacks that work best with tax lien:
- Tax lien + tax delinquent: tax is past due, a dated and money-based sign of pressure.
- Tax lien + absentee owner: the owner gets the tax bill somewhere else, so the house is less personal to them.
