Kyle's assets are tied with Mauricio which is why it is so high. And let's be honest, how long can she live off RHOBH when she has such an expensive lifestyle.
Making a lot of money means nothing when you blow most of it. Look at the way she went from normal housewives to keeping up with the Jones type of housewife when Erika appeared. Also, I do not know of you follow them on social media but her daughters and her are always head to toe in expensive clothes, travelling to expensive places and all via private planes.
She would be worse off than Erika if she left Mauricio since she has her 3 daughters to take care off.
If you google their net worth Kyle on her own is worth 40-50million and as a couple 90-100million. She's been acting since she was a child and possibly has an inheritance? I'm not sure about family money, but in the early seasons the Palm Springs house was hers (it's what caused the big fight in the Limo between her and Kim) and homes there are not cheap!
I personally don't see a big change in lifestyle for her from the early seasons. She's thrown lavish parties since the start, lived in a large house, her collection of insanely priced handbags started before the show. All of her kids, except Portia, are adults and work at the agency... making a lot of money for themselves.
I also don't believe that Erika is poor like she's pretending to be. In her book, on the show and on several podcasts she's said she is in charge of her money. I didn't believe her story that Tom took all her money. She's still got her $40,000 a month glam squad and is still head to toe in designer clothes...
I'm indifferent to Kyle... don't
dislike her, also not a big fan... but that girl ain't poor and won't be in the poor house if she got divorced
