Generally, most lenders require a 20 per cent deposit, while some lenders will allow you to go down to a 15 per cent deposit.
If you only wish to have a 10 per cent or 5 per cent deposit, you may need to pay Lenders Mortgage Insurance (LMI). LMI is an additional fee that is paid to a third-party insurer. Often this fee can be added to the loan.
You also need to factor in bank fees, legal fees, and stamp duty.
