How do I best use my access facility as a savings mechanism?

An Access Facility on your mortgage loan allows you to be able to deposit extra funds to your home loan that you have over and above the minimum required installment and is a very effective way to save as, by reducing the outstanding balance on your mortgage loan, you will reduce the interest that you pay.  You are therefore effectively saving at the bond interest rate, which is considerably higher than the interest earned on a savings account at a financial institution, whilst still permitting you the flexibility of withdrawing your savings when needed.  Naturally, by exercising the discipline of not withdrawing your savings, your will be making capital repayments to your loan, which will enable you to repay the loan over a shorter term, resulting in a saving of total interest paid.
