Important Disclaimer: This calculator provides estimates only and should not be considered financial advice. Actual borrowing capacity, grants, and stamp duty will depend on your individual circumstances, lender assessment criteria, current government policies, and property specifics. Interest rates are indicative. Always consult with a licensed mortgage broker or financial advisor, and verify current grant eligibility with your state revenue office. Calculations assume: 30-year loan term, principal and interest repayments, owner-occupied property, and standard lending criteria. Grant amounts and stamp duty concessions are current as of November 2025 but may change.

  3. Tax Considerations: Applies ~25% tax estimate on gross income
  4. Income Multiple Cap: Maximum loan capped at 6x annual income
  5. Net Disposable Income: Only uses 90% of available funds (keeps 10% buffer)
