Sounds like a good idea, Littleroses. My parents and my in laws both gave their children their houses - like your daughter, we had to wait a few years (I didn't remember it being seven), but weren't in any hurry, still not - obviously they would be able to live in their homes for as long as they wanted to.
It made things easy when my dad died in March this year. My sister and I already owned his house though we hadn't wanted to think about that.
Certainly something to consider in the future.
