Khloe Kardashian's boyfriend, Tristan Thompson, who is going to be her baby daddy soon, is stepping up his real estate game for the sake of his family.

"Tristan Thompson's plan to simply rent a place in L.A. went out the window as soon as the couple found out she was pregnant. He is said to be looking to buy a pad in Bel Air, Bev Hills or the Hollywood Hills.

"Khloe and Tristan were out hunting for a rental for him in July, looking for places in the $60k a month range. Our sources say now that he's planning to become an L.A. homeowner ... his budget's around $20 million." TMZ reports.
