Refinancing Your Sydney Home Loan, 2026 Step-by-Step
Refinancing replaces your current home loan with a new one, either at the same lender or a different one. Done correctly, it saves thousands per year. Done poorly, it costs in break costs, new LMI, or a worse structure. This guide covers every step.
The most reliable trigger to refinance: your fixed rate is about to expire. The second most reliable: you haven't reviewed your loan in 2+ years. Lenders consistently offer better rates to new customers than to loyal existing ones. A 20-minute review costs nothing. I do these daily and the average saving I find is $4,000–$6,000 per year.
Step 1, Know Your Current Position
Gather: current interest rate, loan balance, remaining term, monthly repayment, any fees your lender charges. This is your baseline for comparison.
Step 2, Calculate Your Potential Saving
Annual saving = Loan balance × Rate difference. Example: $750,000 × 0.5% = $3,750/year saving. Monthly: $312.
Step 3, Calculate Switching Costs
- Discharge fee (current lender): $150–$400
- Application fee (new lender): $0–$600 (often waived)
- Valuation: $0–$300 (often waived)
- Government transfer fees: $150–$200
- Fixed rate break cost: varies, get a quote from your lender
Step 4, Break-Even Analysis
Break-even months = Total switching costs ÷ Monthly saving. Example: $1,200 ÷ $312 = 3.8 months. If you'll hold the loan longer than 4 months, switching makes financial sense.
Step 5, Choose the Right Lender
The lowest advertised rate isn't always the best for your situation, it may have conditions that don't apply to your LVR, income type or loan size. We match your profile to the lender whose actual pricing delivers the best outcome, across 50+ lenders.
Step 6, Apply
Documents typically needed: 3 recent payslips, 2 years tax returns (self-employed), council rates notice, mortgage statement, ID. We prepare and lodge the application. Assessment to formal approval: 5–10 business days.
Step 7, Valuation
New lender orders a property valuation to confirm LVR. Most are desktop (automated, fast, free). Full valuations occasionally required, typically waived by the lender.
Step 8, Settlement
New lender pays out your existing loan. Title transfers to new lender. You receive a new loan schedule with your new rate and repayment. Total time application to settlement: 2–4 weeks.
Step 9, Update Direct Debits
Update any direct debits or salary credits linked to your old loan account. Transfer offset balance to your new offset account.
Common Refinancing Mistakes
- Applying to multiple lenders simultaneously, damages credit score
- Refinancing mid-fixed-term without checking break cost first
- Chasing cashback without comparing the underlying rate over your expected hold period
- Not checking whether LMI applies at the new lender (if LVR above 80%)
- Unnecessarily extending the loan term, reduces repayments but increases total interest paid significantly
