Justin Timberlake Cuts SoHo Penthouse Price Again by Nearly Half a Million

Justin Timberlake's reaching Crazy Gideon status ... slashing prices like a madman for a penthouse he's desperately trying to unload.

Justin just slashed the price to his SoHo crib by another $400k ... and it's now down to $6.35 mil. Great deal and, at this point, it's a steal. Remember ... Justin originally listed the pad back in March for $7.995 million ... and the only action was a series of price reductions.

Tough to see why Justin's struggling to get it off his back ... the ultra-modern 2,600 sq. ft. pad features a wraparound terrace, which is 853 square feet, and by NYC standards that's HUGE.
