Many Australian home loans that are interest-only actually require payments to be made on a fully amortising basis after a number of years.

You decide to borrow $**600,000** from the bank at an interest rate of **4.25**% pa for 25 years. The payments will be **interest-only** for the first **10** years (t=0 to 10 years), then they will have to be paid on a **fully amortising** basis for the last **15** years (t=10 to 25 years).

Assuming that interest rates will remain constant, what will be your monthly payments over the first 10 years from now, and then the next 15 years after that? The answer options are given in the same order.
