You’ll save a tens of thousands in interest and not have any payments to worry about when you are older.
I’m really adverse to debt as my parents had huge debt worries when I was younger, and id rather not give banks unnecessary money.
Luckily we’re in a position when we can overpay/use an offset.
We’re currently ten years in and I’m hoping we’ll be paid off in another five, or at least the offset means paying no interest. I know that sounds incredibly boring and privileged.
