How Does Refinancing a Home Loan Work in Australia? A Step-by-Step Guide
Refinancing a home loan can be a smart financial move for Australian homeowners looking to save money, access equity, or consolidate debt. But the process can seem complex if you’ve never done it before. This guide breaks down everything you need to know about refinancing your mortgage in Australia, from the initial decision to settlement. Whether you’re chasing a lower interest rate or unlocking the value in your home, understanding the steps involved will help you navigate the journey with confidence.

Why Refinance Your Home Loan?
Homeowners refinance for many reasons. According to the Australian Bureau of Statistics (ABS), over $20 billion in housing loans were refinanced in December 2024 alone, highlighting how common this strategy has become. Here are the top motivations:
1. Secure a Lower Interest Rate
Even a small rate reduction can lead to significant savings over the life of your loan. For example, switching from a 6.5% rate to 5.8% on a $500,000 loan over 25 years could save you over $50,000 in interest. With the Reserve Bank of Australia (RBA) cash rate target at 4.10% as of May 2025, many lenders are offering competitive variable and fixed rates, making it a prime time to shop around.
2. Access Home Equity
If your property value has increased, you may be able to refinance and borrow against the equity. This is often used for renovations, investing in another property, or funding large expenses. Lenders typically allow you to access up to 80% of your property’s value without paying Lenders Mortgage Insurance (LMI).
3. Consolidate Debt
Rolling high-interest debts like credit cards or personal loans into your mortgage can simplify repayments and reduce overall interest costs. However, this extends the term of the debt, so it’s important to weigh the long-term implications.
4. Change Loan Features
You might want to switch from a variable to a fixed rate, add an offset account, or gain access to redraw facilities. Refinancing allows you to tailor your loan to your current financial situation.
5. Avoid a Mortgage Cliff
Many borrowers coming off fixed-rate terms face a sharp increase in repayments. Refinancing can help you secure a more affordable rate before you roll onto a higher standard variable rate.
Step-by-Step Refinancing Process
Refinancing typically takes 4–8 weeks from application to settlement. Here’s what to expect at each stage:
Step 1: Assess Your Financial Situation
Before approaching lenders, review your current loan details: interest rate, remaining term, monthly repayments, and any exit fees. Check your credit score through agencies like Equifax or Experian, as a score above 650 generally qualifies for competitive rates. Calculate your property’s current value using recent sales data or a professional appraisal, and determine your equity position.
Step 2: Research and Compare Loans
Don’t just look at the advertised rate. Compare the comparison rate, which includes most fees and charges. Use online tools like the Moneysmart mortgage calculator or speak with a mortgage broker who can access a panel of lenders. Key features to compare include:
| Feature | Why It Matters |
|---|---|
| Interest rate | Directly affects your repayment amount |
| Comparison rate | Reflects the true cost including fees |
| Offset account | Reduces interest by offsetting your balance |
| Redraw facility | Access extra repayments if needed |
| Loan term | Shorter terms save interest but increase repayments |
| Fees (application, ongoing, discharge) | Can add hundreds to the cost |
Step 3: Choose a Lender and Apply
Once you’ve selected a loan, complete the lender’s application. You’ll need to provide:
- Identification (driver’s licence, passport)
- Proof of income (recent payslips, tax returns, or business financials)
- Statements for existing loans and credit cards
- Details of assets and liabilities
- Council rates notice for the property
The lender will assess your borrowing capacity based on your income, expenses, and existing debts. Lenders use the Household Expenditure Measure (HEM) or your declared living expenses to calculate serviceability. As of 2025, most lenders apply a 3% serviceability buffer above the loan rate.
Step 4: Property Valuation
Your new lender will order a valuation to confirm the property’s worth. This is often a desktop or kerbside valuation, but sometimes a full inspection is required. The valuation determines your Loan-to-Value Ratio (LVR), which affects your eligibility and whether LMI applies.
Step 5: Loan Approval
If your application meets the lender’s criteria, you’ll receive conditional or unconditional approval. Conditional approval means the lender needs more documentation; unconditional means you’re formally approved and can proceed to settlement.
Step 6: Legal and Settlement Process
Your new lender will work with your existing lender to arrange settlement. You’ll need a solicitor or conveyancer to handle the legal paperwork, including the discharge of your old mortgage and registration of the new one. Settlement usually occurs electronically via the PEXA system. On settlement day, the new lender pays out the old loan, and any remaining equity is transferred to your nominated account.
Step 7: Post-Settlement
After settlement, update any direct debits linked to your old loan. Set up repayments for the new loan and familiarise yourself with the features, such as an offset account or redraw facility. Destroy any old mortgage documents securely.
Costs of Refinancing a Home Loan
Refinancing isn’t free. Here’s a breakdown of common costs in Australia as of 2025:
| Cost | Estimated Amount |
|---|---|
| Discharge fee (current lender) | $150–$400 |
| Application/establishment fee (new lender) | $0–$600 |
| Valuation fee | $0–$300 (often waived by lender) |
| Legal/conveyancing fees | $500–$1,000 |
| Mortgage registration fee | $150–$200 (varies by state) |
| Lenders Mortgage Insurance (if LVR >80%) | Varies, can be thousands |
| Break costs (if breaking a fixed rate) | Can be substantial, depending on interest rate movements |
Total costs typically range from $1,000 to $3,000, but many lenders offer cashback incentives of $2,000–$4,000 to offset these. Always calculate the break-even point: divide total costs by monthly savings to see how long it takes to recoup the expense.
Lender Requirements for Refinancing
To qualify for refinancing, you generally need:
- A good credit score (650+ is ideal)
- Stable employment and income (usually 3–6 months in current role)
- An LVR of 80% or less to avoid LMI, though some lenders accept higher LVRs
- Sufficient equity in the property (typically at least 20%)
- A clear repayment history on existing debts
Self-employed borrowers may need to provide two years of tax returns and business financials. Lenders also assess your debt-to-income ratio; ideally, total debt repayments should be under 30–40% of your gross income.
How to Compare Refinance Loans Effectively
Don’t be swayed by headline rates alone. Here’s a framework for comparison:
1. Look Beyond the Rate
Consider the comparison rate, which includes most fees. A loan with a low rate but high ongoing fees could cost more over time.
2. Evaluate Loan Features
An offset account can save you thousands in interest, but it often comes with a higher rate or annual fee. Decide which features align with your goals.
3. Check for Flexibility
Can you make extra repayments without penalty? Is there a redraw facility? These features add value if your circumstances change.
4. Read the Fine Print
Look for hidden costs like annual package fees, late payment penalties, or discharge fees. Some loans have introductory rates that revert to a much higher standard variable rate after a year or two.
5. Use a Mortgage Broker
A broker can compare loans from multiple lenders and negotiate on your behalf. They’re paid by the lender, so there’s usually no direct cost to you. Ensure your broker holds an Australian Credit Licence (ACL) or is a credit representative.
Common Pitfalls to Avoid
- Resetting the loan term: Refinancing back to 30 years may lower repayments but increase total interest paid. Consider keeping the remaining term.
- Not accounting for all costs: Factor in break fees if you’re leaving a fixed rate early. These can be thousands of dollars.
- Chasing cashbacks without comparing rates: A $3,000 cashback might be tempting, but if the rate is 0.5% higher than another lender, you could lose more over time.
- Overlooking LMI: If you’re borrowing more than 80% of the property value, LMI can add a significant upfront cost.
FAQ
