At 6.30% over 30 years, the principal-and-interest payment on a $670,000 mortgage is about $4,147.12 per month. Australian home loans are commonly variable-rate (or fixed for 1–3 years) over a 30-year term, often with an offset account.
No — this is principal and interest only. Council rates and home insurance are paid separately on top. In Australia, Lenders Mortgage Insurance (LMI) usually applies with less than a 20% deposit and varies by lender.
Over the full 30-year term at 6.30%, total interest on a $670,000 mortgage is roughly $822,963. Overpaying reduces this substantially.
