I know this is a somewhat controversial topic but be good to get some thoughts from outside the family.
DD19 got good A levels ,went travelling and has now got a degree apprenticeship in the police starting next year.
She has always worked whilst in college and now in a zero hours job.
We have never charged her rent and her £ is her own , we are not wealthy but don’t need it from her at all. When she starts her apprenticeship I think she should start to pay us some nominal rent, I can keep it to one side for a deposit when she moves out but I kind of think she needs to do this vs my DH who thinks we don’t needthe £ and let’s just trust her to do her own saving. She is quite a good saver but I think it is good practice for her to start to see some of her £ go out at the start of each month.
Sorry for the long post-thought be good to provide context.
