01Before you switch

What to check besides the rate

A lower rate is the start of the comparison, not the end of it.

  • Break costs on a fixed loan

    Ending a fixed rate early can cost thousands, depending on how rates have moved. Ask your lender for a figure before you decide.

  • Fees, now and ongoing

    Discharge, application, settlement and government registration fees, plus any annual package fee on the new loan.

  • Features you use

    Offset accounts, redraw, extra repayments and splitting between fixed and variable all affect what the loan is worth to you.

  • The loan term

    Resetting to 30 years lowers repayments but can add interest. Keeping your current term usually saves more overall.

Refinancing with Mustang Mortgage

02Questions

Refinancing questions

What does it cost to refinance?

Usually a discharge fee from your current lender, any application or settlement fees on the new loan, and government fees to discharge the old mortgage and register the new one (in NSW, registering a mortgage is $182.73 from 1 July 2026). If your current loan is fixed, a break cost can be the largest item. If you borrow more than 80% of the value, lenders mortgage insurance may apply again.

How long does refinancing take?

It depends on the new lender and on how quickly your current lender releases the loan. We tell you the current turnaround for the lenders we recommend, and the secure client portal helps us collect your documents in one go.

Is a longer loan term a good idea when refinancing?

It lowers each repayment, but you pay interest for longer, so the total cost can go up even at a lower rate. The calculator shows both the monthly difference and the difference over the life of each loan.

Can I just ask my current lender for a better rate?

Yes, and it is often worth asking first: there are no switching costs if your lender agrees. Knowing what other lenders would offer you helps that conversation.
