I have recently applied at ANZ to convert my home loan from P&I to IO in preparation for renting it out however I have been advised that I will be unable to keep the interest rate discount of 0.70% which I currently have if the loan changes to IO. It was explained that the current loan will be paid off, with a new loan established as IO. As the criteria for the 0.70% discount has tightened substantially over the last couple of months they will be unable to pass on the 0.70% if I choose to go this path. They have offered me 0.50% discount which basically means my interest rate would increase by 0.20% to change to IO. I’m looking for advice on how to persuade ANZ to reconsider or override this rule because sometimes I’m not the best with choosing the right words to use. What options or ideas would you recommend? I'm trying to setup the loan as IO so that I can increase my cash flow and leave it in the 100% offset account reducing the Principal as I save up for the next deposit.
