Understanding premium on the bid

[Jonathan Keiser]

Hello everyone. I am a newbie in real estate. I am interested in looking into tax liens in Indiana. I understand the 10% first 6 months and 15% the second 6 with the 1 year redemption period. I am unclear when it comes to bidding over the price of the lien. If you bid over the price of the lien what happens to the excess bid when the homeowners pays the tax lien? You get the lien amount back with interest but do you get the excess premium back as well? Any help would be greatly appreciated. 

Thank You 

Jon
