Kylie Jenner is becoming quite the real estate aficionado ... because she just threw down millions on yet ANOTHER new mansion.
The $12 million, 13k square foot house in Hidden Hills comes equipped with 8 bedrooms, 11 bathrooms and a gigantic pool and outdoor living space.
Kylie's been swooping up properties left and right in the last year ... the latest purchase is her fourth. Our sources say the 19-year-old -- yes, 19 -- has already moved in and plans on making this one her permanent residence.
You'll remember ... Kylie's starter home was a modest $2.7 mil crib when she bought when she was 17. Then she moved on to a $6 mil place near Kim and Kanye before plunking down $4.5 mil on a home used for guests and as a work space for her cosmetics line.
We reached out to Kylie's agent Tomer Fridman who wasn't available for comment.
Home, sweet home homes.
