The most decorated Olympian of all time has reportedly sold his Baltimore townhouse for $1.25 million, despite buying it for $1.699 million in 2007. The listing is still active, which may mean that it's only in escrow. We imagine that losing 450K on this 4,000-square-foot, three-bedroom condo is probably not a big deal to Phelps, and that this one small loss will soon be distant memory amongst his many wins. [Curbed]
