The tax sale runs in two stages
Indiana sells the lien, not the land, and it does it twice. The county holds an annual tax sale under IC 6-1.1-24; parcels that draw no bidder do not simply go back on the rolls, because the county executive acquires the lien under IC 6-1.1-24-6. Those certificates can then be offered again at a commissioners certificate sale under IC 6-1.1-24-6.1, at a price the statute allows to fall below the minimum bid required at the first sale. The redemption clock is set by IC 6-1.1-25-4 and runs much shorter on a second-stage certificate than on a first. A great deal of cheap Indiana acreage has come through that second sale.
