  • Family Mortgage: This option should only be ticked 'yes' if it’s specifically on the Family Mortgage Product.
  • Interest Only: This option should only be selected if it is a short term (i.e. 10 years or less) interest only mortgage where the repayment vehicle has no associated cost, most commonly downsizing.
  • 5 Year Fixed Rate: For this option, you only need to input the pay rate if the product selected is fixed for five years or more. In such circumstances the assessment rate is pay rate.
  • Retired and 65+: Selecting this option applies the reduced Social Security contributions applicable to such applicants.
