Dear OP, you are obviously the daughter who wants your dad to use up a year of the precious time he has left on the earth so you can grab some more cash.
Nobody, nobody at all, is entitled to buy a property. My parents weren't able to do that until they were in their 50s, and they were only able to leave us 26 thousand pounds each from the sale of that when they died, as it was just a humble flat and there were three of us.
We were so incredibly grateful that they left us anything at all. I used to always say to my mum she could leave whatever she had to the cat and dog home if she chose, she owed us absolutely nothing, having already sacrificed so much - as all parents do when they raise their kids.
My mother owed me nothing financially at all - just like your parents owe you absolutely nothing. They've already raised you, looked after you and now it is their turn to enjoy the fruits of their long and arduous labour in any way they see fit.
Even if they were millionaires, they would still owe you sweet eff all.
So, be grateful for any help your parents choose to give you, as millions are in no position to help their kids financially at all.
Understand that buying a house, at any age, is a privilege not a right, work as hard as your parents have and save your own money. Meanwhile, you'll be fine renting, like the majority of people around the western world do.
If you're lucky, your hard working parents may choose to leave you some money when they die.
But there's always the cat and dog home.
