Michael Jordan -- Mansion Auction FAILS ... Again

As great as Michael Jordan was at basketball ... is how much he sucks at real estate -- 'cause, once again, no one was willing to poney up the dough at an auction for his mega-mansion ... TMZ Sports has learned.

The 7-acre Chicago compound would've gone to literally anyone willing to shell out $13 mil at today's auction ... but yet again, there were no takers on the property.

We've covered the entire saga of MJ's real estate nightmare -- he yanked the house off the auction block at the last second on Nov. 22 ... in hopes of selling it today, but no dice.
