Scooter Braun -- Droppin' Epic Bachelor Pad Before Fatherhood

EXCLUSIVE
Scooter Braun kissed bachelorhood goodbye last year ... and now he's ready to cash out on his ultimate bachelor pad to the tune of nearly $12 million. 

Braun's 5,300 sq. ft. former man palace is cavernous ... no doubt Justin Bieber crashed more than once in the 4-bed, 5-bath digs Scooter bought in 2011 for $5.7 million. 

The testosterdome has a pool, a cabana (for babes), a koi pond (for the koi), and massive floor to ceiling glass walls -- which possibly inspired Biebs to score a glass house too.

Scooter's wife Yael is about to have their first kid ... so the timing's right to scrub all traces of his single days. Last year they dropped $13 mill on a more family-friendly 11,137 sq. ft. mansion in Brentwood.

The baby's definitely going home to a huge crib.
