Why should anyone look at my bank statements, atalanta? Well, HMRC will want every entry for the past 7 years from the date of my death, for a start. They'll be looking for evidence of gifts made. I had to employ a specialist accountant when my mother died, since the Revenue claimed that she had made £300,000 in gifts out of capital, monies over and above her income after expenses, in 7 years, a claim based on their analysis of her bank accounts.
If I did take this somewhat unusual course, rather than gift the house outright, it occurs to me that it would be better done by a trading company, of which I or the family have control, assuming that is within the company's powers, though I suspect that the Revenue are alive to this possibility and would look twice at it, though my daughter is not a director (or shareholder, come to that).
