Their "income" largely comes from Bayleigh's father and his investments. Their vehicles are rented as is their downtown apartment in LA. They just bolt when the lease is up.
I think Swaggy must be at least somewhat self-made. He had a business selling trading courses for $300 each and made a few 100K the last year. I dont know how he does it, but he claims to make millions day trading. You can call day trading high-risk gambling but there's some expertise there.
And Bay was a flight attendant for several years. Just because her family's well-off doesn't mean they're at the level that they can bankroll a lavish lifestyle like that, even though a lot of it might be for show.
