Frequently Asked Questions

Common questions answered regarding Fixed Rate Loan and Variable Rate Loan.

Yes. Many Australian borrowers choose a split loan (e.g. 50% fixed and 50% variable) to combine repayment certainty with offset flexibility.

An offset account is a transaction account linked to your variable loan. The cash balance offsets your loan principal, so you only pay interest on the net difference.
