When John Edmonds moved to the Stardust Ranch in Buckeye, AZ, 20 years ago, the neighbors didn’t exactly bring pie. Instead, a man wielding a machete showed up on the doorstep to inform John and his wife, Joyce, that he was the one who kept the monsters away.

Things only got stranger from there and now, after decades of paranormal encounters, the Edmondses are ready to sell the Rainbow Valley property. This working ranch, currently in use as a horse rescue, is available for $5 million. The 10-acre property includes a 3,500-square-foot home with five bedrooms and four baths.

The home has a pool, RV hookups, and a private well, all behind a gated entrance. There are four horse corrals, a pole barn, arena, tack room, kennel, and commercial-size hay barn.

Also on the property are two portals that Edmonds believes lead to another dimension and through which aliens travel. One is located in the back of the property and the other is in the living room fireplace. He claims to have killed 18 aliens with a samurai sword that he keeps in the living room.

The couple say they discovered that the previous owners threw all their possessions into the pool rather than moving them to their next house. They've also experienced unexplained bruising and syringe-like punctures on their bodies. Joyce believes she was attacked in the master bedroom—which she now refuses to enter.

They’ve had animals mutilated, and one dog died shortly after attacking an alien. Edmonds got a tissue sample from an alien he stabbed and submitted it to biophysicist and crop circle researcher W. C. Levengood. Levengood, according to Edmonds, believed that the sample’s composition was unlike anything found on this planet and could be linked to similar samples found at cattle mutilation sites.

The home has been featured on the Travel Channel's "Ghost Adventures" and multiple paranormal and alien websites. A neighbor has also witnessed unusual activity on the property, which is relatively isolated.

“This property’s not going to be for the faint of heart,” says listing agent Kimberly Gero. “It’s going to be for someone who has a true interest in the paranormal and aliens and isn’t afraid to live with them. And it wouldn’t hurt if they had an interest in horses, too.”

The eventual buyer must sign a document acknowledging that there is no guarantee of having an alien encounter—or of avoiding one.

“Buy at your own risk,” advises Gero. “If it happens, it happens—but if it doesn’t, it’s not on [Edmonds]. But I don’t think you’re going to find another property quite like this one.”
