Tips for Switching Home Loans Without Losing Your Interest Rate Advantage
Refinancing your home loan can be one of the most effective strategies to reduce costs, unlock better loan features, or consolidate debt. But in a rising interest rate environment, many Australian homeowners hesitate to switch because they worry about losing the competitive rate they already have.
The good news is that, with careful planning and the right strategy, you can refinance without sacrificing your interest rate advantage — and in some cases, even improve it.
This guide explains when and why to switch home loans, how to avoid common pitfalls, and the best tactics to secure a competitive rate when refinancing.
Why Switch Home Loans?
Refinancing means replacing your existing loan with a new one, either with your current lender or a different provider. Borrowers typically refinance to:
- Secure a lower interest rate
- Access better loan features, such as offset accounts or redraw facilities
- Adjust loan terms, such as shortening the loan term to save on interest
- Consolidate debts into one manageable repayment
- Unlock equity for renovations, investments, or other financial goals
Challenges of Switching in a Rising Rate Environment
While switching home loans can deliver significant benefits, it’s not without challenges, particularly when interest rates are rising.
- Higher rates for new customers: Even if you locked in a great rate years ago, new loans may be priced higher in the current market, potentially eroding the benefit of refinancing.
- Exit and establishment fees: Costs such as discharge fees, application fees, and valuation fees can add up and reduce the financial advantage of switching.
- Stricter loan approval criteria: Lenders may apply tighter rules for new borrowers, particularly if your financial situation has changed.
To switch effectively, you need to approach refinancing with a strategy that protects your rate advantage.
Tips for Switching Without Losing Your Rate Advantage
1. Evaluate Your Current Loan
Start by reviewing the details of your existing loan:
- Current interest rate — is it still competitive?
- Loan term — how much time is left?
- Loan features — do you have access to offset accounts, redraw facilities, or flexible repayment options?
- Fees — are you paying ongoing or hidden charges that reduce the value of your loan?
Understanding your current setup helps you assess whether refinancing is worth it.
2. Compare the Market
Use online comparison tools or speak with a mortgage broker to research current loan offers. Focus on:
- Comparison rates — which include the interest rate and most fees, giving a clearer picture of total cost
- Promotional offers — some lenders offer cashback or discounted rates for refinancers
- Loan features — ensure the new loan offers the flexibility or features you need, such as extra repayments or an offset account
3. Negotiate With Your Current Lender
If your current rate is competitive, try negotiating before switching.
Steps to negotiate:
- Collect competing offers from other lenders
- Contact your lender’s retention team (often called the mortgage discharge team)
- Highlight your loyalty, repayment history, and the better offers you’ve found elsewhere
Lenders often prefer to match or improve offers rather than lose your business.
4. Understand Break Fees and Exit Costs
If you are on a fixed-rate loan, breaking the agreement early may trigger significant break fees. These are typically calculated based on:
- The remaining loan balance
- The time left in your fixed term
- The difference between your fixed rate and current market rates
For example, breaking a $400,000 fixed-rate loan with two years remaining could cost $10,000 or more. Always calculate whether the savings from switching outweigh these fees.
5. Look for Refinance Deals
Many lenders offer incentives for switching, such as:
- Cashback offers
- Reduced or waived application fees
- Special promotional rates for refinancers
For example, a $3,000 cashback deal could cover the cost of exit and setup fees, making the switch financially viable.
6. Consider Splitting Your Loan
If you are reluctant to give up a competitive fixed rate, consider splitting your loan:
- Fix part of your loan at the current rate
- Move the rest to a variable rate with a new lender
This approach gives you the stability of fixed repayments while letting you explore better variable options.
7. Refinance to a Loan With Lower Fees
Sometimes the best savings come not from a lower rate, but from a lower-fee loan.
For example:
- Loan A: 5.0% rate with $400 annual fees
- Loan B: 5.2% rate with no fees
If the interest savings on Loan A are less than the cost of the fees, Loan B may be the smarter choice.
8. Use an Offset Account
Switching to a loan with an offset account can reduce the interest charged on your loan, even if the rate is slightly higher.
Example:
- Loan balance: $500,000 at 5.0%
- Offset account balance: $20,000
- Interest charged only on: $480,000
The savings from an offset account can help compensate for minor differences in headline interest rates.
9. Shorten Your Loan Term
When refinancing, consider keeping your current repayment amount rather than reducing it.
Example:
- Current loan: $500,000 at 6.0% over 30 years (monthly repayment: $2,997)
- Refinanced loan: $500,000 at 5.0% over 30 years
By maintaining the $2,997 monthly repayment, you could save approximately $73,000 in interest and pay off the loan five years earlier.
10. Check Your Credit Score
Your credit score influences the rates lenders offer.
Before applying:
- Get a free credit report from Equifax, Experian, or Illion
- Address any issues, such as overdue debts or high credit utilisation
Borrowers with excellent credit scores typically qualify for the most competitive rates.
11. Consider Timing
The timing of your refinance matters:
- If rates are rising, consider locking in a fixed rate before further increases
- If rates are expected to fall, consider a variable loan to benefit from potential cuts
12. Use a Mortgage Broker
A broker can:
- Access multiple lenders
- Negotiate on your behalf
- Find loans with lower rates, better features, or exclusive offers
They can also help calculate the true value of switching after accounting for all fees.
Case Study: Refinancing Without Losing Rate Advantage
Loan amount: $600,000
Current rate: 5.5% fixed (1 year remaining)
Break fee: $6,000
New loan: 5.0% variable with no fees
Monthly repayment at 5.5%: $3,408
Monthly repayment at 5.0%: $3,225
Monthly saving: $183
Break-even point: 33 months ($6,000 ÷ $183)
If the borrower plans to stay in the property long-term, refinancing delivers savings despite the break fee.
Avoid Common Mistakes
- Overlooking fees: Always factor in exit, application, valuation, and legal costs.
- Choosing based solely on rate: Consider flexibility, loan features, and service quality.
- Failing to lock in a rate: Ask about rate-lock options to protect your quoted fixed rate during settlement.
The Long-Term Benefits of Refinancing
By refinancing smartly, you can:
- Save thousands of dollars over the loan term
- Reduce monthly repayments or shorten your loan duration
- Access useful features like offset accounts and redraw facilities
- Simplify financial management by consolidating debts

The keys are:
