OP - i'm confused about the timings you are thinking of, are you planning on your DD living with you forever and wanting her to keep your current family house after you go into a home or are you thinking that when she's in her 20s and ready to move out of the family home you'll buy her a house in her name for herself and want to be certain that wouldn't be taken off her to pay for your care fees?
At the risk of being nosing, how old are you and how good's your health? If you are in your 40s with a 10 year old, and you think you could afford to buy her a house in 15 years time, then she will have that for what, 20 years before it's likely you'll need to pay for care home fees or pay inheritance tax?
I think (although you need to check) if she's living in the family home at the point you move into a care home (and has been for a long time), she can't be forced to sell it to pay for your care - but check that. However, do you think it's likely she'll never marry/move away before she's in her 40s? not go off and have a family of her own? Realistically, unless there's SN you've not mentioned, it's unlikely your house will be her home at the point you need care fees, she might well have bought her own house and be mortgage free before you need care/in a home.
If you are trying to work out a way to ensure she will get to keep your house as well, think about what's going to happen to it for the time you are in a care home. Realistically, your house will be sold if you need long term care because well, in the case of my Grandmother, that would have meant her house standing empty for over 10 years (7 of them in a carehome, the rest at my parents house - funnily enough my mum didn't want to moveback into her childhood home to care for her, Grandmother moved in to my parents' house).
Will you be able to give her the money for a disposit or total costs of her own house when she's first looking for a property of her own?
