The DJ officially parted ways with the 6-bedroom Encino estate, with the sale going through on Thursday for $17,125,000 ... which means he's pocketed a fair amount in the sale, 'cause he bought for quite a bit less a few years ago.

While this is over a million less than his original asking price of $18,999,000 ... Zedd is still walking away in the black, as he nabbed the property from Joe Jonas and Sophie Turner in 2021 for $15.2 million.

The mansion is certainly worth the hefty price tag, too ... boasting 14,779 square feet of living space with all the bells and whistles -- including a gym, sauna, massage room, home theater, pub, wine cellar, professional music studio and vocal booth.

Oh, and there's an outdoor kitchen, putting green and a swimming pool, as well.

Zedd snagged a different Encino mansion in November last year. The hitmaker picked up the 40,075 square foot property by celeb designer Jae Omar and developer, JVE Development for $18.4mill.

Jae also designed Joe and Sophie's former place ... so it's clear Zedd is a fan of the designer's work -- but maybe not enough to own 2 homes in the same neighborhood.

The new estate is certainly an upgrade ... as it features 8 bedrooms, a guest house, Olympic-sized swimming pool, indoor/outdoor wellness spa, fitness area, bowling alley and more.
