Louisiana Tax Lien Sale Auction question

[Joseph Pumilia]

Hi, I am trying to learn about tax lien sales in Louisiana. 

As I understand, the bidder with the lowest % of willing to own wins the auction. 

As I understand it, if you win, you pay the price, say $500. Then, they would pay you back the $500 + 5% penalty + 1% interest per month. However, if you win, you must pay the property taxes going forward until it is repaid. 

Does the owner repay you any of the additional property taxes you paid in excess of the original amount, $500? 

Any help is much appreciated.
