The Hidden Hills property, previously owned by Lisa Marie Presley, isn't too far from Kardashian's mother's home in Calabasas, where the couple has been living since their daughter North was born in June 2013.
According to E! Online, their new digs includes its own vineyard, two swimming pools, two spas, and two BBQ centers.
Ongoing construction prevented the couple from moving into the Bel-Air house, and an insider says they found the renovation process "exhausting." They also decided the estate's land didn't meet their needs.
Kardashian revealed earlier this week that she was taking her husband's last name while posting her passport photo on Instagram. "New passport pic #Mrs.West #NameChange," she wrote alongside the head shot.
