ANZ bank is one of "The Big 4" banks in Australia, so they are going no where, and the Australian government still guarantees deposits up to a certain amount. They currently offer 5.30% in a term deposit. Scroll down. https://www.anz.com.au/personal/bank-accounts/ My fund makes more than 5.30%, but that's a rock solid guaranteed 5.30%. The other thing to consider is the time line of life expectancy. One would need to live X amount of years before the buy v rent goes financially in the buy favor, and at 5.30% interest, and with associated proper costs, those amount of years one must live to see a financial reward between buy v rent pushes out past the average life expectancy.
