1. Fair point, but you say a significant amount of Gen Y already own? I thought that was the major cause of concern over property prices? If a significant proportion of our young adult generation own already then that would indicate to me that property prices are about right. I'm not saying that is the case, I'm not saying it is not, just trying to establish your position on this. Can't go both ways.
My take on this without having data to back it up is that a small percentage are owners, and that the majority are aspiring buyers.
2. Yes. As mentioned the "kids" are the largest group as of the last census.
3. Yes. Not sure of your point though.
Do you mean that because they will be buying property further out there will be less demand for the boomers properties?
