Built in 1949 by the cowboy singer-actor, the forested 3.68-acre property had been donated by Autry's widow, Jacqueline Autry, to the Autry National Center of the American West.
Balconies overlook the acreage, which has winding paths and flower gardens. The grounds also include a guesthouse, a swimming pool and an outdoor entertainment area with a fireplace.
The residential property couldn't be turned into a museum, so the Autry had no reason to hold onto it, trustee Stanley Schneider said. "The sale provided a substantial donation to the museum."
Probst, 48, has hosted the reality show since it started in 2000. He has won four Emmys. Probst declined to comment.
Gene Autry's signature song was "Back in the Saddle Again," but his biggest hit was "Rudolph the Red-Nosed Reindeer." He owned the team now known as the Los Angeles Angels of Anaheim from 1961 to 1997, and died in 1998 at age 91.
The Autrys married in 1981. Jackie Autry, 69, lives in Palm Springs.
The estate came on the market last summer at $6.9 million.
Barbara Robinson and Nichelle Robinson of Hilton & Hyland, Beverly Hills, and Connie Nelson of Coldwell Banker, Studio City, were the listing agents. Thomas O'Rourke of Prudential California Realty, West Hollywood, represented Probst.

Cee Lo Green, who will be one of the judges on the NBC talent competition "The Voice," has leased actor Frankie Muniz's Hollywood Hills-area house, which was on the market for sale at $3,195,000 or for lease at $10,000 a month.
The gated home, built in 1941, has been remodeled with an open floor plan. The kitchen, dining room, living room, family room and two bedrooms occupy the lower level. Upstairs, the master bedroom suite has a sitting area, a fireplace and dual closets. Two additional bedrooms are on the upper level of the 4,200-square-foot home, which has four bathrooms.
Green, 36, who sang the cleaned-up "Forget You" version of his expletive-laced hit single at the Grammys this year, is part of the R&B/hip hop duo Gnarls Barkley. He will join Christina Aguilera and Adam Levine of Maroon 5 on "The Voice."
Muniz, 25, was nominated for an Emmy for playing the title role in "Malcolm in the Middle" (2000-2006). He bought the house in 2006 for $3,499,000 and has been leasing it out.
Justin Mandile and Mary Swanson of Sotheby's International Realty, Beverly Hills, are the listing agents, according to the Multiple Listing Service.
