To challenge some of the thinking a bit... I’m now 40 but i had several periods of living at home rent free and I’ve never had any problems with debt or not realising I’d need to pay bills.
I had a part time job in school/college and the money was mine to keep. I had to save for my own car and pay petrol and insurance.
I had a gap year, I worked for 6 months, saved and travelled for 6 months. I learned to save and was grateful my mum didn’t charge me rent as it made my earning go further.
At uni I worked, took out a loan and paid my way. I wasn’t sent money from home and I wasn’t shocked that I had rent and bills.
After uni I returned home, worked and saved to go travelling again. Didn’t pay rent, again, very grateful.
After travelling I returned home again, lived there for a year rent free, got back on my feet, saved some money and bought a house aged 25. Ive never had trouble with debt or been surprised by mortgage and bills.
My mums policy was that life is hard enough and she’d like to make ours easier.
I was exceptionally grateful to my mother for not charging me rent and as adults myself and my siblings will happily pay maintenance bills, for gardening and cleaning now that she’s elderly and we have disposable income.
Just wanted to show that charging your children rent isn’t the only way to raise capable human beings.
OP what’s your daughters long term plan? Is she saving to move out or buy somewhere? If you don’t need that couple of hundred a month, letting her put it in savings could make a real difference to her future.
