Conditional approval

If you’re applying in a branch or via a Home Loan Expert, we can often give a conditional approval on the spot (subject to eligibility and responsible lending inquiries) for straight forward applications where all required documentation is provided.

Note, if there's a second applicant they will also need to agree to the application and a credit check.

A conditional approval gives you an idea of how much you can borrow, based on conditions and responsible lending inquiries. With this you can now start looking for a house that you could call home.

Once you have a conditional approval there are a few key steps you'll need to take:

  • Find a house that you could call home
  • Do your homework: get builder and council reports, and a valuation
  • Arrange for a solicitor to handle the legal and financial details
  • Make your offer (this can be conditional or unconditional), or bid at auction. You can learn more about the ways to buy here
  • Check the details and sign the sale and purchase agreement
  • Talk to us about the best way to structure for your new home loan, once your offer has gone unconditional, or you've bought at auction
  • Sign the home loan documents with your solicitor. Learn more about this step here
  • Book the movers
  • Pay the balance at settlement and move into your new home!
  • Check the details of your first home loan repayment. It's easiest to make sure your repayment dates coincide with your pay day.
