It's really tough trying to find the balance between helping your adult student child and letting them balance their own money.
My DS has just finished Y2 of a 4 year course. He only gets the minimum loan as our household earns too much ? Our household being me and his stepdad. His own dad earns much less so if he had declared his dad's address as being his main residence he could have borrowed much more maintenance loan. But then would have had even more of a debt at the end. There's no winning route.
DS lived in halls the first year. The loan covered his rent (which also included all bills, wifi etc). All he had to buy was food and general living costs. He lived on campus so no need to travel into town unless for socialising. I gave him some money each month as did his dad.
The second year I reduced my payments a little as he had more than enough to live on. I thought if I kept reducing it a bit he may be inclined to get a job.
. But no.
Hoping he is going to do a few weeks over the summer to at least get some money behind him for the next year.
The system isn't very fair. It should not be down to the parents to fund adult students. Like you, OP - you may earn what some would consider sufficient, but if you live in an expensive area then your outgoings will be a lot higher too.
All I can suggest is for your DD to reallylook into what each university can offer. There are a few bursaries around.
Even though 'her' supermarket isn't in her uni town - she is in a good position due to her previous experience to get a student job at a local one. Even a few hours per week will help out.
Does your DD realise that you actually can't fund her? Or does she just think that you'll magic up some money each month for her spends?
There is time for her to get in a load of overtime at work before Uni starts - maybe that's the path she needs to go down for now - and to rein in her spending.
Fingers crossed it all gets sorted out - and DD gets off to Uni.
