Their parents have sold their home to go do retirement type stuff. I'm guessing it's them funding the private school. Castle needs to sell her house and can't afford to rent in Spain anymore.
Sis has had to sell her home to pay the charges against her doll company. Says she has a new build home all paid for and ready to move in but Castle said about giving her money for a deposit.
No idea about Bruv.
Sis and Bruv are definitely spending much more than they earn on FLP,I think their parents have been bailing them out. Sis husband has a J.O.B.
It's very possible that Castle isn't on track for a cheque this year and might not make it to 5000cc's. With a huge loan meaning to be paid back I can't see how she can carry on much longer. Things suddenly changed after Stockholm. I can't help wondering if she thought she was going to get a bigger cheque, about the same as last year.
We know bots are useless at budgeting and she may have been relying on that cheque desperately to keep afloat.
