Which banks offer a "pregnant pause"?
Historically, St George use to offer a product that had this feature. However, there was very strict criteria to qualify such as at a minimum the loan should not exceed 90 per cent during capitalising period. The loan then gets accelerated repayments once back on track.
An alternative to being restricted to a specific product type is to consider other options such as making extra repayments and then redraw for the period of leave, switching to an interest only loan to reduce the minimum repayment obligations or fixing your loan to provide you with repayment security and help with managing household budgets.
