The basketball star previously listed the home with LA-based real estate agency Compass last December but withdrew the listing and decided to try a new approach: social media.
On Thursday, O'Neal posted a video giving his 15.3 million follows a look inside his 5,217-square-foot home in a gated equestrian community outside Los Angeles (just a few miles from where Kanye and Kim Kardashian West live).
(In October, Justin Bieber posted images of the interior of his home on Instagram, writing in the caption: "I think I wanna sell my home in Beverly Hills who wants it?")
O'Neal's house has five bedrooms, four-and-a-half bathrooms and sits on a 1-acre lot, according to the post.
O'Neal has updated the property, including new carpeting, custom closets and landscaping upgrades, according to a Compass spokesperson, who previously held the listing.
"The house is walking distance from the community center, state of the art gym and tennis courts," O'Neal writes.
Take a look inside.
The first floor includes a family room, two dining rooms, a wine closet/wet bar, a media room, a laundry room, an office and one bedroom.
The kitchen opens to the main living area and has marble countertops and custom cabinetry.
Upstairs, the master suite has dual walk-in closets and a fireplace.
The master bathroom has a Jacuzzi tub.
In the backyard, there is a heated pool, a Jacuzzi and a fire pit.
In addition to the L.A. property, Shaq has a mansion Orlando, Florida that he's owned for more 26 years. He listed that property for $22 million in December 2018. It did not sell and is no longer listed.
