Hi OP,
I think it is a great idea to give your children their inheritance now and have them secure and you happy in your home with your partner.
I recently came into my inheritance at the age of 30 and i was able to buy myself a new home which is exactly what my grandparents wanted me to do with the money. Not only have i bought the house of my dreams but having some financial security has enabled me to follow many of my career dreams too, in many ways it has made me more independent, secure, confident, mature, it has also given my future family a great start in life.
There is nothing wrong with embracing a better life for yourself, if someone helps you get a home it does not mean you become lazy and idle it just makes way for more opportunity, I also love the fact that i am now in a position to help others, with my career changes i am really in a position to give back to the community, My boyfriend has also had a break from the 13 years of hard grafting running his business as a landscaper and he is now able to follow some of his dreams.
Setting someone up in a home may not take away from them learning independence, it may add to their lives enormously.
It is a good time to buy a long term property investment, if your children are going to buy a house in the future with it anyway then i can see why parents are thinking this way now.
