Billie Eilish grew up in a two-bedroom home in the Highland Park neighborhood of Los Angeles with her brother, Finneas, a place the Ocean Eyes singer still calls home. On an episode of Conan O'Brien Needs a Friend podcast released in March 2023, where the siblings joined to chat with O'Brien, Finneas revealed how his sister hadn't really "moved away," although he had.
In the podcast, Billie also opened up about wanting to feel like an adult by having her own space but concluded it by saying:
"...also now I'm like, I like my parents being around and I like my mom coming and doing stuff with me."

In the meantime, her brother Finneas moved out of the house to live in a Loz Feliz mansion with his girlfriend and YouTuber Claudia Sulewski in 2019.

In 2019, the British singer and actress Leona Lewis sold her Glendale estate home for about $2.3 million. While the sale made headlines, the identity of the buyer wasn't revealed. Squareyards later found that Lewis' equestrian estate was just ten minutes away from Billie Eilish's current home.
Furthermore, the realtor who made the deal happen was the same one who had worked with Finneas previously on the purchase of his properties. The Glendale estate is a horse-friendly home, which aligns with the singer-songwriter's love for them.
The 2100 sqft single-story home has three bedrooms and bathrooms, a freshly renovated kitchen, a swimming pool, and a stylized sunken conversation pit. It also comes with a separate guest house, goat pens, and a paddock for horses. Beyond the home, Billie Eilish currently owns five cars, including a Dodge Challenger Hellcat and a McClaren 600LT.
Billie's brother, Finneas, has two properties with his girlfriend

On the Conan O'Brien podcast, Finneas talked about his experience of living away from his family, saying:
"I did move away. And I think when you don't live with your folks anymore, you're just, yeah. It's nicer to, it makes you more grateful to do everything with them. So I'm like, now, when I have a free night, I go and hang out with my parents. That's the first thing I think of doing."
In 2020, Finneas purchased another property—an oceanfront cottage in Malibu, situated between Las Flores Beach and Pacific Coast Highway. The 1250 sqft home was built in 2005 and has an open-concept floorplan with three bedrooms and two bathrooms. It is complete with hardwood flooring, oceanfront decks, a fireplace, a swing chair, and a jacuzzi and cost the songwriter $5.2 million.
