Question:

John borrowed $300,000 from a bank for buying an apartment three years ago. He has been paying the monthly mortgage repayments (at month end) with an annual fixed interest rate of 6% for three years, and the mortgage has seven years remaining term. Since the inflation has reverted back to the long-term target, the Reserve Bank decided to pause hiking the benchmark cash rate. As such, major commercial banks started to offer special deals to attract new customers. John is considering two deals listed below.

• Bank BNZ: a 10-year mortgage with a fixed interest rate of 5.4% p.a. The monthly mortgage repayments need to be made at the end of the month. A bonus of $5,000 is offered to customers for transferring an existing mortgage from another bank. (Hint: the bonus can be used to reduce the mortgage balance)

• Bank DBA: a 7-year mortgage with a fixed interest rate of 6.2% p.a. The quarterly mortgage repayments need to be made at the beginning of the quarter (the first repayment is due now). A bonus of $4,000 is offered to customers for transferring an existing mortgage from another bank.
