I did this, so did three of my friends. We are all fucked financially now.
That going on girlie holidays, hair cuts, make up, spending a months wages on clothes. Nights out. I've never done it. Yes it's all material but I think it's how you find yourself.
Uni, travelling and further education- out the window as you have to keep on the treadmill to pay the bills.
Trying to keep my story short I rent privately without a hope in hell of buying. The instability and additional cost that comes with that is huge and has a massive impact on my children.
I fucked up and they are paying the price.
My three friends who did the same, they've gone on to "marry well" (not the ones they moved out with) so are ok, but each of them have battled huge debt, have struggle to find "home" and we joke our midlife crisis are going to be amazing.
When I look back (and I'm sure this isn't the case for you as your posting here) we were all trying to give ourselves some sort of stability we weren't getting at home.
My advice, keep her home! You can't force her but make home more attractive, she wants freedom and to play "house". So if you've got a way of giving her that whilst keeping her there, do it. You can sell it to her on the guise of I don't want you to rent, you need to finish your education and save for a deposit. Getting driving licenses and cars
The thing with our country is if you fuck up with education, your on your own. You get one chance with all the support after that it's much harder to start it again.
Make sure she knows if it goes tits up she can come home. Tread carefully with your wording so you don't push her away. She hasn't had the freedoms of adulthood yet, let alone throwing those away to play house.
