Bloody hell it gets worse!
Since it’s your dad suggesting a contribution could you prepare a sample budget for him showing that this level of contribution is madness
Budget
Tuition fees - paid for up front by the government Via tuition fee loan to be paid back after graduation
Accommodation Costs paid for by granny
So all niece need to pay for is books, food, transport costs, mobile phone, food and entertainment.
This could be paid for by -
Minimum maintenance loan is £4200 (assuming dads income is high). Divided by 9 (3 months uni holidays) this is £466 per month.
A part time job. When I was at uni I worked 6 hours on a Saturday but FT during uni holidays.
Contribution by dad of £120 per month or £1080 per year (based off nine months)
So without any contribution from your parent or you she already has potentially £5280 per annum or £586 per month to cover food, phone bill, entertainment, books and transport without getting a PT job. Plus the 50k depending on what has happened to this.
my brother owns two foreign properties plus the house they’re living in, but he’s got a £2k/month mortgage on that. - if he’s that desperate for cash he could sell one or both of his foreign properties.
