THE 5,300-square-foot mini- mansion that “Extreme Makeover: Home Edition” built for an Atlanta couple four years ago was set to be sold yesterday at a foreclosure auction.

The couple lost the house after they borrowed $450,000 to start a new business, which failed.

There was no immediate word on the size of the winning bid yesterday.

Another “Extreme Makeover” homeowner in Idaho lost his home in bank foreclosure last month when he could not repay a $400,000 loan.
