Regular loan repayments are not required. However you are free to make voluntary repayments of any amount (and redraw these amounts, for a fee) or repay the loan via lump sum repayments at any time at no extra cost or penalty.
Provided you are not in default, the loan will be repaid when:
(a) the mortgaged property is sold on your death or death of the last borrower;
(b) the mortgaged property ceases to be your principal place of residence or that of the last surviving borrower; or
(c) in case of an investment property or holiday home, on the death of the last surviving borrower.
