Joe Jonas It Ain't Cake by Ocean ... But Mansion with Crazy View Will Do

1/29/2016 3:48 PM PST

Joe Jonas is making life post-Gigi Hadid look real good -- no easy feat -- thanks to the new Hollywood Hills mansion he just scored.

The place, which is on the market for $4.6 million,  is being sold by celeb real estate agent Carl Gambino of Westside Estate Agency -- but Joe's not buying ... he'll only be in it for a bit ... for $40,000 a month! The 3 bedroom, 3.5 bathroom home is the perfect bachelor pad -- spectacular city views, a circular drawing room, pool, and awesome cliffside lawn. 

Yeah, Joe's new band DNCE is doing THAT well. 

This is the second sick Hollywood Hills crib he's landed.

Check out the pics -- the hidden Murphy-style bar in the living is vintage James Bond baller.
