Someone has a great house but you don't?

Let no fear disturb your peace
Though one's wealth and house increase,
Death shall all his glory end;
Naught shall after him descend.

Though the world his praise will tell,
When to self he doeth well,
And though while of life possessed,
He his soul has always blessed,

With his fathers he shall lie,
Where no light shall meet his eye.
Man in honor when not wise,
Like the beasts that perish, dies.
Psalm 49:16-20

Note also Luke 12:16-21
16 And he told them a parable, saying, "The land of a rich man produced plentifully, 17 and he thought to himself, 'What shall I do, for I have nowhere to store my crops?' 18 And he said, 'I will do this: I will tear down my barns and build larger ones, and there I will store all my grain and my goods. 19 And I will say to my soul, Soul, you have ample goods laid up for many years; relax, eat, drink, be merry.' 20 But God said to him, 'Fool! This night your soul is required of you, and the things you have prepared, whose will they be?' 21 So is the one who lays up treasure for himself and is not rich toward God."
