What this includes
Duty is a state tax and depends on whether you will live in the home. LMI is a lump sum if the deposit is under 20%, not a monthly PMI line.
Australia
The monthly number is not the payment.
Four planning tools for Australian buyers and owners: monthly repayment cost, a price ceiling, refinance break-even, and NSW, VIC or QLD duty with LMI.
Mortgage
Principal and interest plus insurance and strata / council rates — the monthly number the payment quote leaves out. Extra principal is a first-class input.
Afford
The highest price at which owner cost is 28% of gross income, with how lenders in this market actually test it.
Refinance
Months to recover switching costs from a lower payment. Compare the break-even period with how long you expect to keep the new loan.
Stamp & taxes
NSW, VIC and QLD duty for owner-occupiers, first home buyers and investors.
