The House thing is so much the luck of the draw. e.g.
A - an only child, parents die in their 60's , inherits family home, moves family in mortgage free -
B - parents both need long term care, their house sold to cover care costs, B has to shell out for extras -
C - widowed mother dies, but sister, her long term carer gets the house
D - grandmother dies, parents move into her cottage, D + sister sell family home and each buy a house, with small mortgage
E - parents die, rented flat, E spends house deposit savings on 2 x funerals
Could go on but you get the idea! It is a lottery.
