“The X-Files” star David Duchovny believes the truth is out there … that his out-of-this-world Malibu estate is for sale for the earthbound price of $12.5 million.

This leisure paradise was built as an ultra-modern, easy indoor-outdoor living experience … perfect for unobstructed views when watching the skies for unidentified flying activity — or just sunsets, if you prefer.

The residence, in the exclusive gated neighborhood of Malibu’s Point Dume … 3 bedrooms in the main house, comprising 3,577 square feet — not including the separate structure outside — on an acre of lush land, with beach-key access to the nearby Pacific.

A gravel motor court with plenty of parking space — for FBI vans, black helicopters, or just your SUV — leads up to the the place, with a custom wooden front door, soaring ceilings inside, recessed lighting, and skylights throughout the place … perfect for letting in natural light, and the occasional peek at any passing paranormal activity.

There are white oak floors in the bedrooms and en-suite baths, and the chef’s kitchen has stone countertops, custom cabinets, and premium Miele appliances … the smart-home system controls security cameras, the lighting, the intercom, and Sonos audio throughout.

There’s a lap pool outside with a wood deck, near a sunken firepit with built-in seating … and even more entertainment options, including an outdoor kitchen with a Wolf grill, mini fridge, and a dedicated dining space. Spa amenities include a built-in Jacuzzi, an outdoor shower, and a cold plunge.

The exterior building out back — literally a transported train caboose — can be set up as a gym, office, or a guest suite. It has pocketing glass doors, a covered deck with built-in heaters, and an en-suite bath with a skylit-tiled shower and stone vanity.

The landscaping is lush, with mature citrus trees, and a comprehensive security system … ensuring the property’s privacy for any secret meetings, or maybe just a pool party.

Duchovny’s owned the place for more than 20 years, even writing a novel and recording podcasts there. Take a closer look at this supernatural offering!
