NBA star DeMarcus Cousins has sold the AMAZING Las Vegas estate where he’s lived since 2017 … and made a 7-figure profit to boot.

The pad is unreal — complete with a home theater, basketball court and a massive outdoor pool with waterfalls and a slide!!

Cousins listed the property back in September 2020 for $8 million … and got pretty close to his asking price … closing the sale at $7.5 mil.

And, since he bought the place for $6.5 million, it turned out to be a pretty solid investment.

No word on who purchased the estate — but the new owner will have 10 bedrooms, 12 bathrooms, a sports media room … and there’s an elevator inside the home!!

There’s also a state-of-the-art gym — perfect for the COVID-conscious 2021 world we’re all still living in.

Cousins is currently a free agent who has earned more than $91 million in his career … the only question now — Where’s he gonna live next!?
