What Is Refinancing and How Does It Work?
Refinancing means replacing your existing home loan with a new one, either from your current lender or a different lender. Borrowers refinance to secure a lower interest rate, access better loan features, consolidate debt, or tap into built-up home equity. In 2026, Australian borrowers continue to refinance at high volumes, with the ABS Lending Indicators series reporting external refinancing of around $17-19 billion per month (ABS series 5601.0, refer to the latest release for current figures).
The refinancing process works by taking out a new loan to pay off your existing mortgage. Your new lender settles the outstanding balance with your old lender, and the mortgage security (your property title) is transferred. You then make repayments to your new lender under new terms. The entire process typically takes 2-6 weeks and can be done without selling or moving out of your property.
Switching Lenders
Move your loan to a new lender offering a lower rate or better features. This is the most common form of refinancing, accounting for approximately 65% of all refinance activity in Australia.
Renegotiating Terms
Stay with your current lender but renegotiate your rate, loan term, or features. Often called a "rate match" or internal refinance, this avoids discharge and setup fees entirely.
Accessing Equity
Borrow more than your current balance by tapping into your property's increased value. Equity release can fund renovations, investments, or debt consolidation - up to 80% LVR without LMI.
Australian homeowners collectively hold over a trillion dollars in accessible home equity, with national dwelling values continuing to grow at high single digits over the past two years (CoreLogic Home Value Index). Many borrowers have significantly more equity than when they first took out their loan. Even without accessing equity, simply securing a rate 0.50% lower on a $600,000 loan saves approximately $183 per month or $2,196 per year - that is $65,880 over the remaining life of a 30-year loan.
When Is the Right Time to Refinance Your Home Loan?
RBA research shows borrowers who actively switch lenders save an average of $2,800 per year compared to those who stay loyal. Refinancing at the right moment can mean the difference between thousands in savings and unnecessary fees.
The best time to refinance is when you can secure a rate at least 0.25% lower than your current rate, your fixed rate period is ending, or your financial circumstances have improved since you first borrowed. In 2026, with the RBA cash rate at 4.35% and lenders competing aggressively for refinancers, conditions are favourable for switching.
Timing your refinance correctly can mean the difference between saving thousands and wasting money on unnecessary fees. Research from the RBA shows that borrowers who actively switch lenders save an average of $2,800 per year compared to those who stay with their original lender. The "loyalty tax" - where existing customers pay higher rates than new customers - remains a persistent feature of the Australian mortgage market.
Decision framework: should you refinance now?
Switchers save ~$2,800/yr · RBA research
- Your rate is 0.25%+ above current market rates
- Your fixed rate period is about to expire
- Your income has increased since you first borrowed
- Your credit score has improved significantly
- Your property value has risen (more equity = better rates)
- You need features your current loan lacks (offset, redraw)
Wait before refinancing
- You are mid-way through a fixed rate term (break fees)
- You plan to sell the property within 12 months
- Your income has recently decreased or is unstable
- Your LVR is above 80% and you would pay LMI again
- The rate difference is less than 0.15% (unlikely to cover costs)
- You have recently changed jobs (lenders want 6+ months)
Is now the right time? In 2026, the average variable refinance rate sits around 6.56%, while the best new-customer rates start from 5.89%. That 0.67% spread means a typical borrower on a $600,000 loan at the average rate is paying around $262 per month more than someone on the lowest available rate - or roughly $3,144 per year. Compare refinance rates to see where you sit.
How Do You Calculate If Refinancing Is Worth It?
Use the break-even formula to compare your switching costs against your monthly savings. If you plan to hold the loan beyond the break-even point, refinancing is financially worthwhile.
The break-even formula is simple: divide your total switching costs by your monthly savings. If you plan to hold the loan longer than the break-even period, refinancing is financially worthwhile. On a $600,000 loan, even a 0.25% rate reduction saves $1,104 per year, breaking even within 8-27 months depending on your switching costs.
Break-even formula
Break-even (months) = Total Switching Costs ÷ Monthly Savings
If break-even is less than the time you plan to hold the loan, refinancing pays off.
Worked examples: $600,000 loan over 25 years remaining

These calculations assume a principal and interest loan with 25 years remaining. Your actual savings will depend on your loan balance, remaining term, and the specific rates available to you. Remember to factor in all costs - not just the obvious ones. A mortgage broker or our refinance rate comparison can help you run exact numbers for your situation.
How Is Refinancing Different for Investment Properties vs. Owner-Occupied?
Investment loans carry rates 0.20-0.50% higher than owner-occupied, but offer tax-deductible interest. Documentation and LVR requirements also differ between the two.
Investment property refinancing involves higher interest rates (typically 0.20-0.50% above owner-occupied rates), stricter LVR limits, and additional documentation requirements such as rental income evidence. However, investment borrowers benefit from tax-deductible interest, which offsets some of the rate premium.
| Factor | Owner-Occupied | Investment Property |
|---|---|---|
| Typical rate (variable, P&I) | 6.14%-6.86% | ~0.20-0.50% above owner-occupied |
| Maximum LVR (no LMI) | 80% | 80% (some lenders cap at 70%) |
| Interest tax deductible | No | Yes (negative gearing applies) |
| Documentation required | Standard income and expenses | Standard + rental income, lease agreement, property manager statement |
| Typical approval time | 2-4 weeks | 3-5 weeks |

For investment property owners, the after-tax cost is what matters most. An investment loan rate around 7.06% (typical 0.50% premium over the current owner-occupied average of 6.56%) at a 37% marginal tax rate has an effective after-tax cost of approximately 4.45%, making it cheaper than many owner-occupied loans on a net basis. When refinancing an investment property, prioritise maintaining your tax deduction by keeping investment and personal debt separate. Cross-collateralisation (using your home as security for your investment loan) should generally be avoided, as it limits your flexibility to sell or refinance either property independently.
What Are Cash-Back Refinance Deals and Are They Worth It?
Lenders advertise cashbacks of $2,000-$4,000 to attract refinancers, but a lower ongoing rate often delivers more value over the life of the loan.
Cash-back offers provide a lump sum payment (typically $2,000-$4,000) when you refinance to a new lender. While attractive, cash-back loans often carry a slightly higher interest rate. On a $600,000 loan, even a 0.10% higher rate costs $3,600 over 5 years - potentially outweighing a $3,000 cash-back.
Cash-back vs lower rate: which saves more?
| Scenario | Rate | Cash-back | Monthly Repayment | Total Cost (5 Years) | Net Benefit |
|---|---|---|---|---|---|
| Cash-back deal | 6.09% | $3,000 | $3,632 | $217,920 | $214,920 |
| Lower rate (no cash-back) | 5.89% | $0 | $3,555 | $213,300 | $213,300 |
| Difference (lower rate wins by) | $1,620 better | ||||

Comparing cash-back offers: A cash-back deal makes sense only if the underlying rate is comparable to (or better than) the best non-cashback rates. In many cases, a lower ongoing rate represents more total saving over 3-5 years than a one-off cash payment. Comparing the total cost of the loan over your expected holding period - including switching costs and the upfront incentive - gives the most accurate picture. Our accredited broker partner can model the total cost for your circumstances.

Can You Refinance with Bad Credit or If You're Self-Employed?
Specialist lenders, low-doc products, and experienced brokers make refinancing possible even with credit scores below 600 or non-standard income.
Yes to both, though you may face higher rates and stricter conditions. Borrowers with credit scores below 600 can access specialist lenders offering refinance products, while self-employed borrowers typically need 1-2 years of tax returns and BAS statements. A mortgage broker is invaluable in these situations.
Refinancing with bad credit
What to expect
- Interest rates 1-3% higher than standard products
- Maximum LVR of 70-80% (more equity required)
- Specialist or non-bank lenders (Pepper Money, Liberty, Bluestone)
- Higher fees and fewer features (no offset in some cases)
How to improve your chances
- Pay all bills on time for 6-12 months before applying
- Clear any defaults or judgments where possible
- Build equity - property value growth helps your LVR
- Use a broker who specialises in non-conforming loans
Refinancing when self-employed
Full-doc requirements
- 2 years personal and business tax returns
- ATO Notice of Assessment (2 years)
- 4 quarters of BAS statements
- ABN registered for 2+ years
Rate premium: 0-0.25% above standard
Low-doc alternative
- Accountant's letter declaring income
- 6-12 months BAS statements
- 6 months business bank statements
- ABN registered for 1+ year
Rate premium: 0.30-0.75% above standard
Self-employed borrowers account for approximately 20% of all Australian mortgage holders. The key challenge is that self-employed income can fluctuate, making it harder for lenders to assess long-term serviceability. If your tax returns show increasing revenue over 2+ years, you are in a strong position. Lenders like Athena, Macquarie, and ING have streamlined processes for self-employed refinancers - compare their current refinance rates.
What Are the Full Costs of Switching Your Home Loan?
Total switching costs typically range from $700 to $3,500 - low enough to break even within months on most rate-driven switches. Break fees on fixed loans can add thousands more.
Total switching costs typically range from $700 to $3,500 for a standard refinance, though break fees on fixed rate loans can add thousands more. The main costs are discharge fees from your current lender, government mortgage registration fees, and potentially a valuation fee. Many new lenders waive application fees for refinancers.
Complete cost breakdown
| Fee Type | Typical Range | Notes |
|---|---|---|
| Discharge fee (old lender) | $150-$400 | Paid to your current lender to release the mortgage. Non-negotiable. |
| Application fee (new lender) | $0-$600 | Many lenders waive this for refinancers. Always negotiate or look for fee-free options. |
| Valuation fee | $200-$600 | Some lenders offer free valuations. Automated valuations (AVMs) are free but not always accepted. |
| Legal / conveyancing | $200-$500 | Handles title transfer and mortgage registration. Some lenders cover this cost. |
| Mortgage registration (govt) | $100-$250 | State government fee to register the new mortgage on the property title. |
| Break fee (fixed rate only) | $0-$20,000+ | Only applies if exiting a fixed rate loan early. Can be substantial. Get a quote from your lender first. |
| LMI (if LVR changes) | $0-$15,000+ | Only if your LVR exceeds 80% with the new lender. Often avoidable if equity has grown. |

What Stamp Duty Applies When Refinancing?
Standard refinances do not attract stamp duty in any Australian state. The only government fees are mortgage registration and discharge - typically $100-$250 each.
In most cases, no stamp duty is payable when refinancing your home loan in Australia. Stamp duty applies to property transfers, not mortgage changes. Since refinancing keeps the same property owner on title, you are simply changing lenders, not transferring ownership. The exception is if you add or remove someone from the property title during the refinance.
This is one of the most common misconceptions about refinancing. Many borrowers assume they will face the same stamp duty bill as when they purchased, which deters them from switching. In reality, the only government fees are the mortgage registration and discharge fees (typically $100-$250 per transaction per state), not stamp duty.
When stamp duty may apply
- Adding a spouse to the title - Some states charge stamp duty on the transferred share. NSW offers an exemption for married couples and de facto partners.
- Removing a name from the title - For example, after a separation or divorce. A court order may exempt you from stamp duty in some states.
- Transferring to a family trust or company - This is treated as a property sale for stamp duty purposes in all states.
- NSW mortgage duty - NSW abolished mortgage duty in 2016, so there is no duty on the new mortgage document itself.
Key takeaway: Standard refinancing does not attract stamp duty in any Australian state or territory. You will only pay mortgage registration fees ($100-$250) and discharge fees. If your refinance involves any change to the property title, consult a conveyancer or solicitor to confirm whether stamp duty applies in your state before proceeding.
How to Refinance: Step-by-Step Process
From reviewing your current loan to settlement day, the refinance process moves through six clear stages. Most refinances complete in 2-6 weeks.
The refinancing process involves six key steps, from reviewing your current loan to settlement day. Most refinances take 2-6 weeks from start to finish, with digital lenders completing the process fastest. Having your documents ready before you start can shave a week or more off the timeline.
Review Current Loan
1-2 days
Check your current rate, remaining balance, loan features, exit fees, and any fixed rate break costs. Call your lender for an exact payout figure. Identify what you want to improve - rate, features, or equity access.
Compare Rates
1 day
Use find.deals™ to compare rates from 30+ lenders. Focus on the comparison rate (includes fees), not just the advertised rate. Check for cashback offers, offset accounts, and fee waivers for refinancers.
Apply for New Loan
1-3 days
Submit your application with ID, payslips, bank statements, current loan statement, and tax return. Digital lenders accept applications online in 10-20 minutes. Your new lender handles communication with your old lender.
Property Valuation
3-7 days
Your new lender arranges a property valuation to confirm current market value and your LVR. Some lenders use automated valuations for metro properties, completing this in 24 hours. Full valuations take 3-7 business days.
Approval & Paperwork
5-10 days
Once unconditionally approved, your new lender sends loan documents for signing. Review the contract carefully, including the comparison rate, fees schedule, and loan conditions. Sign digitally or in person.
Settlement & Switch
7-14 days
On settlement day, your new lender pays out your old loan in full. The mortgage is transferred to the new lender on the property title. Your old loan is discharged, and you begin repayments with your new lender.
Total timeline: 2-6 weeks typical. Digital lenders can complete the process in as little as 2 weeks, while major banks may take 4-6 weeks. Having all your documents ready before you start is the single biggest factor in reducing delays.
