Before you rely on a result

  • Use real figures: council rates from the council, levies from the strata manager, rent from a rental appraisal.
  • Check your interest rate assumption. Our defaults use 7%, close to the current average investor rate. See how interest rates affect rental yield.
  • Results are general estimates, not advice. Read our disclaimer.
