Tarek El Moussa and Christina Haack said their 9-year-old son likes to look at real-estate listings before bed

• Tarek El Moussa and Christina Haack's son Brayden is interested in real estate.
• They told Business Insider he likes to look at real-estate listings instead of reading before bed.
• Their daughter Taylor has an eye for design as well.

Christina Haack and Tarek El Moussa are again proving to be ratings gold for HGTV.

The former couple reunited on "The Flip Off," which premiered on January 29. On the show, Tarek El Moussa and his wife, Heather Rae El Moussa, compete against Haack to see who can profit most from a home flip. It became HGTV's highest-rated freshman series since 2022, attracting 4 million viewers during its first episode.

The premiere included plenty of home-renovation scenes, but it also featured details on Haack's split from her ex, Josh Hall, and an emotional conversation between Haack and her first ex-husband.

Haack and El Moussa's two children, Taylor, 14, and Brayden, 9, also appeared in the first episode of "The Flip Off" and offered opinions on their parents' flipping skills.

Speaking to Business Insider ahead of the premiere, Haack and El Moussa said Brayden, in particular, has a passion for real estate.

Brayden El Moussa loves real estate

Discussing their children's appearance on "The Flip Off," both Haack and El Moussa said their kids love real estate.

"They've been with us working and filming and flipping houses since they were born, so they don't know any different, and they love real estate," El Moussa, who also shares a 2-year-old son, Tristan, with Heather Rae El Moussa, said.

Both Taylor and Brayden appeared on HGTV's "Flip or Flop" when they were babies, growing up on camera as their parents' fame grew. They have also appeared in the former couple's separate series, like "The Flipping El Moussas" and "Christina on the Coast."

El Moussa told BI that Brayden is developing his own interest in real estate.

"Our son Brayden, he's at our house looking at houses online all the time," he said. "He's with Christina looking at houses all the time."

"He likes to do it before bed," Haack said, adding that Brayden asks to log into the multiple-listing service with her. "Like, some kids like bedtime stories. He's like, 'I want to go and search the MLS and see what's for sale in the neighborhood.' Truly, he loves it."

Brayden also recently appeared on "The Flipping El Moussas," investing his own money in a flip they were working on. Brayden contributed $25 to the flip, doubling his money when the house sold.

Haack said the episode was "so cute."

"He has really cute ideas, and he's really smart," Heather Rae El Moussa agreed. "So is Taylor. Her design eye is so amazing."

"She has an amazing eye," Haack said. "She always decorates her own room. She loves to help just designing houses, so I feel like it's definitely in both of their futures."

Episode two of "The Flip Off" airs on HGTV at 8 p.m. ET.
