Starter house or stay in one nicer house from the start is better?

I’m 20, & i’m debating on if i should move into a nice house that i want from the start or move into a small starter house & sell it & move into a nicer house. I see people staying in a smaller houses for years & im confused on why they don’t sell it even if they didn’t finish paying it off because they can still sell it so i’m cautious about that even though it seems smart.
