Even Kylie Jenner can't always get what she wants in the luxury real estate market.The reality TV star and beauty mogul has sold her longtime Hidden Hills mansion for $15.3 million – almost $5 million less than the price she initially hoped to fetch.Jenner, 29, had listed the sprawling California property for $20.25 million in March, but the eventual sale represents a considerably more modest payday than she may have anticipated.Still, the deal marks a profit on the home she bought for $12.05 million in late 2016, when she was just 19.And while one mansion has now left her property portfolio, Jenner is far from packing up her life in the celebrity enclave.The sale comes as she continues to build a lavish custom estate in Hidden Hills, which has been tipped as her future love nest with boyfriend Timothee Chalamet. As she works on the development, which is expected to feature an approximately 18,000-square-foot main residence, a 12-car underground garage, guesthouse, sports court, resort-style pool and a separate security building, Jenner has condensed her property portfolio.The eight-bedroom property which she most recently sold sits on a 1.4-acre lot and it was one of three homes she purchased in Hidden Hills over an 18-month period. Kylie Jenner has sold her longtime Hidden Hills mansion for $15.3 million – almost $5 million less than the price she initially hoped to fetchShe bought her first for $2.7 million at the age of 17, followed by another nearby property for $6 million.While she sold the other two homes relatively soon after buying them, the largest became a longtime base for the star and her two children, daughter Stormi and son Aire, whom she shares with rapper Travis Scott.Over the years, Jenner extensively renovated the residence, which was built in 2014 and marketed as being designed for both everyday living and grand-scale entertaining.For the transformation, Jenner hired celebrity interior designer Martyn Lawrence Bullard.Speaking to Architectural Digest in 2019, Jenner said she wanted a 'fresh, fun vibe' that matched how she was feeling at the time, adding: 'Color was essential. I love pink, and I wanted a lot of it!'Bullard described the property as Jenner's 'first really grown-up house' and he went about incorporating a distinctly glamorous but playful look, with bold artwork, custom furnishings, colorful lighting, lavish dressing rooms and a highly personalized 'glam room'. Jenner revealed that her closets and glam room were 'very personal' to her, right down to the size of each drawer, so they could accommodate her specific beauty products and clothes. The home also featured a lavish entertainment area with a bar, billiard table, arcade games and cocktail tables designed with cutouts for ice, champagne and caviar.
