In New Orleans Tax Sales are conducted by online auctions. The price is set at the amount of taxes owed, plus costs. The bidder who offers the least percentage of ownership wins. The city issues the winning bidder a tax sale certificate who becomes the tax sale purchaser and holds a tax sale title.
Tip: Never bid less than 100% ownership, just to get the property. I know you want the winning bid. However, if you decide to quiet the title later, owning less than 100% can be a nightmare. It won’t be worth it. Don’t do it.
Keep in mind that what you bid is just your initial investment. You will have to pay subsequent years property taxes to maintain your interest in the property. And you may have additional costs to keep the grass cut and avoid environmental liens.
The owners have up to three years from the day the tax sale is filed in the public records to redeem the property. In order to redeem the owners must pay tax sale purchaser the amount of taxes paid, plus a 5% penalty and 1% interest per month (12% per year).
After the redemption period is over (if the owners have not redeemed) the tax sale purchaser becomes the owner and can file suit to quiet the title. The goal of a suit to quiet title is to have the courts recognize the rights of the tax sale purchaser.
