How can I get additional interest rate relief?
If you decide to revert to an eligible variable rate home loan, you may consider linking a Mortgage Offset Account. The Mortgage Offset Account can be used as a full transaction or savings account. The balance in this account is offset against your loan balance, reducing the interest payable on that loan and helping you save interest and pay off your loan sooner.
