According to TMZ, Kylie's new abode boasts six bedrooms, seven bathrooms, a pool, wine cellar and a huge walk-in closet, all spread across over 7,000 square feet.
It has only been a year since the Keeping Up with the Kardashians star bought her first house, for which she paid $2.7 million.
The Calabasas home is now up for sale and has already received offers of just under $3 million.
A source said: "Their relationship started quite suddenly but it just feels right.
"They are mad for each other.
"She doesn't know why she wasted time with Tyga.
"Kylie's family found the eight-year age gap with Tyga a bit weird, especially as they got together before she turned 18 last year.
Last week, the Canadian rapper shared a picture on Instagram of his and Kylie's jewel-encrusted watches, with the caption: "Diamond battles with @kyliejenner (sic)"
And the post caught the eye of the her former boyfriend, as Tyga then shared a photo of his own jewelled time piece, writing alongside the picture: "Diamond battles".
The Rack City hitmaker recently admitted he "still loves" Kylie.
When asked if the difference in age played a factor in their break up, he said: "Um, uh, I think, you know, we're both just focusing on our lives, our individual lives right now, you know? Sometimes things don't work out. But, you know, I love her."
When asked if there would always be love between them, Tyga simply added: "For sure."
