According to Trulia, the 19-year-old has just snapped up another home in Hidden Hills, California. The mansion, which was listed for $12.4 million, is her third real estate purchase since May, and by far the most expensive.

Built in 2015, the eight bedroom, Cape Cod style home spans 13,200 square feet and sits on 1.4-acres. It comes with a gourmet kitchen, a home theater, sliding walls of glass, a game room, wine storage, a gym, a massage room, a pool, and a spa.

Plus there’s a private one-bedroom guest house with a kitchenette, sitting room, separate entrance, and courtyard.

This recent acquisition joins the $6 million Hidden Hills spread Jenner bought back in May, along with the neighboring $4.5 million home she nabbed in August.

Plus there’s the property she still owns in the nearby gated Calabasas community. That one’s on the market for $3.9 million.

We can’t wait to see how much of Hidden Hills the youngest member of the Jenner/Kardashian clan will own before she turns 21.
