What is refinancing?

Refinancing is when you take out a new home loan to replace your existing home loan. This can be with your existing lender or a new one.

Why should I refinance my home loan?

There are many reasons customers may wish to refinance their home loan. It might be to obtain a better interest rate and lower monthly repayments, or to access different features such as redraw and unlimited extra repayments.

For some, it might be to leverage the equity in their property to conduct home improvements, purchase a new vehicle or consolidate debt. Whereas for others, it might simply be a case of wanting to switch to a lender that truly cares about them and provides the level of service they need.

What are the costs involved in refinancing?

When refinancing, it is important to consider the costs involved. Discharge fees, early payout fees and Lenders Mortgage Insurance (if your loan is less more than 80% of the property value) are usually the main ones to be aware of.

How do I refinance my home loan?

Before you do anything else, it's a good idea to review your existing home loan to understand its terms and conditions, how much you're currently paying in rates and fees, and the costs associated with refinancing.

Once you've got a handle on this, you’ll be able to see how it compares to the competition. While the interest rate will always be an important factor, there are other things to consider such as offset, redraw, and the ability to make extra repayments without incurring fees. These features can make it easier for you to save on interest and pay off the loan sooner.

When comparing interest rates, remember to review the comparison rate, as this includes any upfront or ongoing fees and charges, thereby better reflecting the true cost of the loan in question. Once you're ready to apply, you can do so via online application form, calling us on 133 282, or visiting your local branch.

Will my property need to have a valuation?

Most lenders will require your house to have a valuation completed. This doesn’t necessarily mean a valuer needs to come to your house. Some valuations are done electronically by looking at similar properties in your area.

The type of valuation your lender will require depends on how much you are looking to borrow, where your house is located and the type of house you own. Most lenders will pay for your first valuation as part of your application.

How much equity is required to refinance?

While most customers refinance their home loan with at least 20% equity, it’s possible to do so with as little as 5%. However, if your equity is less than 20%, Lenders Mortgage Insurance will need to be factored into the loan.

Important Information

Rates are current as at 30 July 2021 and subject to change.

Great Southern Bank, a business name of Credit Union Australia Ltd ABN 44 087 650 959, AFSL and Australian Credit Licence 238317. Lending criteria, limits, conditions, and fees apply. Applications are subject to credit approval.

1 The Boost is not available on business accounts.

2 Discounts off the Basic Variable and Offset Variable Reference Rate are available to (a) new home loans with a minimum application amount of $100,000; or (b) switching or restructuring of the home loan you already have with us when it includes new borrowing of at least $10,000; for new home loan applications received on or after 30 July 2021. Published interest rates are inclusive of any discounts off the respective Reference Rates. Interest rates and discounts vary based on the loan purpose (owner occupier and investor), repayment type (principal and interest, interest only, construction) and Loan to Value Ratio (LVR). Maximum LVR applies and includes Lenders Mortgage Insurance and Great Southern Bank loan setup fees where applicable.

3 Great Southern Bank may withdraw or amend this offer at any time without notice. A change in your loan purpose, your repayment type or your loan product will permanently end your entitlement to the discount and your interest rate will revert to the relevant Basic Variable or Offset Variable Reference Rate.

4 LVR means ‘Loan to Value Ratio’. It is the amount of your loan divided by the valuation of your property, calculated as a percentage. For example, if you apply for a loan of $400,000, which will be secured by a property valued at $500,000, your LVR is 80%. We calculate your LVR at the time we approve your loan and your discount won’t change because of changes to the LVR during the life of your loan.

5 Fixed Rate loans are available to (a) new home loans with a minimum application amount of $100,000; or (b) switching or restructuring of existing home loans.

6 On expiry of the fixed rate period, the loan reverts to the Standard Variable Principal & Interest Owner Occupier or Investor Reference Rate (as applicable) which applies at the time of expiry.

7 A $200 minimum withdrawal amount applies for redraws conducted in-branch.

8 You must maintain a minimum balance of $500 in each offset account to obtain an offset benefit. You will also not receive any interest on the funds in your offset accounts.

9 A daily transfer will refund any amounts paid in advance in excess of the total advance repayments allowed during the fixed rate period unless sufficient to pay out the loan in full (in which case an Early Payout Fee may apply). Excess funds will be transferred to the nominated deposit account, which must remain open for the fixed rate period.

+ $3,000 cashback is for new owner occupier or investor refinance home loan applications received between 02/08/2021 and 31/10/2021 and settled by 31/01/2022. Offer not available for switching of a home loan that you already have with us. Minimum home loan refinancing amount of $250,000 and maximum 80% loan to value ratio. Limit of one $3,000 cashback per application (regardless of number of loans e.g. split loans, security properties or applicants). Equity lines of credit, bridging loans, construction loans and business loans not eligible. Great Southern Bank may withdraw or amend this offer at any time without notice.
