Evander Holyfield Loses Millions On Mansion Auction

Bad news: It was at a public auction, he actually owes the bank twice that amount ... and he also owes over $200,000 in back taxes.

According to docs filed in Georgia, Holyfield's massive mansion -- 54,000 sq. ft on 234 acres -- outside Atlanta sold at public auction on March 6 ... but part of the money will go directly to Uncle Sam to pay off his back tax bill.

As for the rest ... according to the documents, Holyfield owed more than $14,000,000 on the house -- plus more than $2500 in foreclosure expenses. It's unclear whether the bank is going after him for the balance.
