Refinancing means replacing your current home loan with a new one, either with another lender or restructured with your existing lender. Sydney borrowers typically refinance to cut their rate, release equity, consolidate debt, or escape a loan whose features no longer fit. This guide covers when to move, what it costs in NSW, how the process works step by step, and the honest answer on credit scores, fixed rates and break costs. It also links every refinance calculator and guide we publish, so you can run your own numbers before you speak to anyone.
Why Should I Refinance My Home Loan?
You refinance for one of three reasons: to pay less (a lower rate or fewer fees on the same loan), to unlock equity (borrowing against the value your property has gained), or to restructure (switching from interest only, adding an offset, splitting fixed and variable, or removing an ex-partner). Most Sydney borrowers who have not reviewed their loan in two years or more find at least one of the three applies, because lenders reserve their sharpest rates for new customers, not loyal ones.
The wrong reason to refinance is habit or a cashback alone. The right reason is a number: what you save each month after switching costs, which the break-even calculator works out in seconds.
When Should You Refinance Your Home Loan?
You should review your loan whenever the saving from switching would outweigh the cost of switching within about 12 to 18 months, and most borrowers who have not reviewed their loan in two years or more will clear that bar. The trigger events are predictable.
- Your fixed rate is about to expire. Loans typically revert to a standard variable rate that is rarely the sharpest available. Reviewing 8 to 12 weeks before expiry gives you time to settle a new loan the week the fixed term ends.
- You have held the same loan for two or more years. Lenders compete hardest for new customers, so existing borrowers tend to drift above the market over time. This is the loyalty tax pattern, widely reported across the Australian market.
- Your property value has risen. A lower loan-to-value ratio can qualify you for sharper pricing tiers, and may open up equity for renovations or investment.
- Your circumstances changed. A pay rise, a new job, paying out a car loan, or finishing a probation period can all improve what lenders will offer you, subject to assessment.
- Your loan lacks features you now need. An offset account, a redraw facility, or the ability to split fixed and variable are reasons to move even without a rate cut.
If none of those apply and your rate is already competitive, the right answer can be to stay put. We tell clients that regularly; a refinance that does not leave you better off fails the point of the exercise. Our guide on when you should refinance walks through each trigger in more depth, and these Sydney refinancing scenarios show how the decision plays out for real borrower types.
How Much Does It Cost to Refinance in NSW?
For most variable-rate borrowers in NSW, the total cost of refinancing lands between roughly $500 and $1,500, and lender waivers often push it toward the bottom of that range. Here is where the money goes.
| Cost | Typical range | Notes |
|---|---|---|
| Discharge fee | $150 to $400 | Charged by your current lender to close the loan |
| Government fees | $200 to $400 | NSW mortgage discharge and registration fees, per title |
| Application fee | $0 to $600 | Charged by the new lender, frequently waived for refinancers |
| Valuation fee | $0 to $300 | Often free; desktop valuations are common for standard properties |
| Fixed rate break cost | Varies | Only if you exit a fixed term early; can be significant, always calculated first |
| Lenders mortgage insurance | Usually $0 | Only applies if your new loan exceeds 80% of the property value |
| Our fee | $0 | Paid by the new lender on settlement, never by you |
Two of those line items deserve respect. Break costs on a fixed loan are set by the lender's funding position, not a published table, so they must be quoted before you commit; more on that below. And if your loan-to-value ratio is above 80%, lenders mortgage insurance can apply to the new loan even though you may have paid it once already, which usually changes the recommendation. We check both before any application goes in.
How Much Can You Save by Refinancing?
Cutting 0.50% off a $600,000 loan with 25 years remaining saves roughly $181 a month, which is more than $2,100 a year, every year, for a few hundred dollars of one-off switching costs. Larger balances save proportionally more, and even a 0.25% cut is usually worth taking on loans above $500,000. Run your own figures through the refinance savings calculator, then check how quickly the switching costs are recovered with the break-even calculator.
The reason savings of this size sit there uncollected is the loyalty tax: lenders price their front book (new customers) more sharply than their back book (existing customers), so the longer you hold a loan without reviewing it, the wider the gap tends to grow. It is a widely reported pattern across the Australian lending market, not a quirk of any one lender, and it is why the biggest savings usually belong to borrowers who have not touched their loan in two or more years.
Recently settled: a Sydney investor's four-property restructure released $4M in equity while cutting the rate 0.34%, worth about $27,000 a year on the new book; another Russell Lea refinance took a $5.3M loan to a $6.9M facility at 0.50% less, releasing $1.6M. Actual outcomes, anonymised; results depend on circumstances.
Is It Worth Refinancing for 0.25% or 0.50%?
Usually yes for 0.50%, and often yes for 0.25% on larger balances, because the one-off switching cost is small against the recurring saving. The table below shows the approximate monthly and annual difference a rate cut makes on a principal-and-interest loan with 25 years remaining.
| Loan balance | 0.25% lower rate | 0.50% lower rate |
|---|---|---|
| $500,000 | ~$78/month (~$930/year) | ~$155/month (~$1,855/year) |
| $600,000 | ~$91/month (~$1,095/year) | ~$181/month (~$2,175/year) |
| $750,000 | ~$116/month (~$1,395/year) | ~$232/month (~$2,785/year) |
| $1,000,000 | ~$155/month (~$1,860/year) | ~$309/month (~$3,710/year) |
Illustrative arithmetic only, based on a mid-6% starting rate and 25 years remaining. Not a quote or an available rate; your figures depend on your loan and lender assessment.
On an interest-only loan the arithmetic is even simpler: every 0.25% off the rate saves about $21 a month per $100,000 of balance. So if switching costs you $1,000 and saves $150 a month, you are ahead in roughly seven months and every month after that is yours. Run your own numbers in the refinance savings calculator or the break-even calculator, which tells you exactly how many months it takes to recover your switching costs.
One caution: if refinancing resets your loan term from 25 years back to 30, the lower repayment partly reflects the longer term, not just the better rate. Keeping your repayments at the old level after you switch preserves the full interest saving and often shaves years off the loan.
What Happens When You Refinance? The 6-Step Process
In plain terms, what refinancing involves is six steps over 2 to 4 weeks from application to settlement, and as your broker we run every step except signing. Here is the sequence.
- 1. Review and comparison (days 1 to 3). We look at your current loan, rate, balance and property value, then compare your position against 50+ lenders. As credit assistance providers under ACL 511092, we operate under the Best Interests Duty: the recommendation has to be the right loan for you, not the easiest one to place.
- 2. Repricing check. Before any application, we can ask your current lender to sharpen your existing rate. If they match the market, you keep your loan and skip the switching costs entirely. If they do not, the comparison has already been done.
- 3. Application (week 1). We package your payslips, loan statements, ID and liabilities and lodge with the chosen lender. One application to one lender, selected first, rather than scattergun applications that mark up your credit file.
- 4. Valuation and assessment (weeks 1 to 2). The new lender values your property, often by desktop within a day or two, and assesses your income and commitments against its lending criteria.
- 5. Approval and documents (weeks 2 to 3). Formal approval is issued and loan documents follow. You sign; we check everything matches what was recommended.
- 6. Settlement and discharge (weeks 3 to 4). The new lender pays out the old loan, the old mortgage is discharged with NSW Land Registry Services, and your new loan begins. Your repayments, offset and direct debits switch over from settlement.

See Where You Stand in 60 Seconds
Answer a few questions and find out whether refinancing is likely to leave you ahead, before anyone touches your credit file.
Can You Refinance With the Same Bank?
Strictly speaking, asking your current bank for a better rate is repricing, not refinancing: your loan stays where it is and only the rate changes. And it is the smart first move. We tell clients to do it, and we do it for them before any application goes anywhere, because a successful reprice costs nothing, touches no credit file, and takes a phone call rather than weeks.
What typically happens: retention teams often move, but usually part of the way. A borrower paying 0.60% above the market might be offered 0.25% off to stay, which is better than nothing and still worse than the loan they could hold elsewhere. Banks calibrate retention offers to what keeps you, not to what the market charges.
Switching still wins when the reprice leaves you meaningfully above front-book pricing, when your bank will not offer the features or structure you need (an offset, a split, cash out for a renovation), or when a lower loan-to-value ratio qualifies you for a pricing tier your current lender will not match. The honest process is: ask your bank first, get the answer in writing, then compare it against the market. If your bank genuinely matches, stay; you have lost nothing. If it does not, the comparison is already done.
What Is a Cash Out Refinance?
A cash out refinance replaces your current loan with a larger one and releases the difference to you as funds, borrowed against the equity in your property. Because the money is secured by your home, it is priced at home loan rates rather than personal loan or credit card rates, which is why borrowers use it for renovations, an investment property deposit, or consolidating expensive debt.
Lenders assess cash out more carefully than a straight rate switch: most want your total loan to stay at or under 80% of the property value, and they will ask what the funds are for. Larger amounts may need supporting evidence such as a builder's quote or an accountant's letter. The full picture, including typical limits and how lenders treat different purposes, is in our cash out refinance guide for Sydney, and the equity calculator shows how much usable equity you likely have.
Can You Refinance on a Fixed Rate?
Yes, but exiting a fixed term early usually triggers a break cost, so the decision comes down to whether the saving over your remaining term outweighs that cost. Break costs are not a flat fee: they reflect the gap between the wholesale rates when you fixed and wholesale rates now, multiplied across your balance and remaining term. If market rates have fallen since you fixed, the cost can be substantial; if they have risen, it can be negligible. The only way to know is to request a payout quote from your lender, which we do before recommending anything.
For most fixed-rate borrowers the smarter play is timing. Your lender must tell you when your fixed term is ending, but the revert rate they move you to is rarely competitive. Starting the refinance 8 to 12 weeks before expiry means the new loan settles just as the fixed term ends, with no break cost at all. Our fixed rate expiry calculator shows what your repayments look like after reversion and what the timeline should be, and the fixed vs variable guide covers whether to fix again at all.
Does Refinancing Hurt Your Credit Score?
Refinancing places one credit enquiry on your file, and a single enquiry typically has a small, short-lived effect. What genuinely damages a score is a cluster of applications in a short window, which is the pattern lenders read as distress. That is the practical argument for choosing one lender first and applying once, rather than applying to several banks to see who says yes.
Two honest caveats. Closing a long-held account and opening a new one can trim the "account age" component of some scoring models for a while. And comprehensive credit reporting means your repayment history travels with you, which cuts both ways: a clean 24 months of repayments is now an asset you carry to the new lender. If your file already has problems, see the bad credit section below before applying anywhere.
How Often Can You Refinance?
There is no legal limit; you can refinance as often as the numbers justify it. In practice, most borrowers who stay on top of their loan refinance or reprice every two to three years, which is roughly how long it takes a once-competitive rate to drift above the market.
The practical constraints are cost and credit file hygiene. Each switch repeats the discharge and government fees, each application adds an enquiry, and some lender incentives claw back if you leave within a set period, so serial switching for small gains can go backwards. The discipline that works: do a proper review every year, which is free, and only transact when the break-even is comfortably under 18 months. We run that annual review for existing clients as a matter of course.
Refinancing When Self-Employed or With Bad Credit
Both are workable; they just narrow the lender list, which is exactly when a broker across 50+ lenders earns their keep.
Self-employed. Most lenders want two years of tax returns and notices of assessment, but policies differ widely on add-backs, company structures and how recent your figures must be. Some accept one year; alt doc lenders can work from BAS statements, business bank statements or an accountant's declaration, subject to assessment, usually at a modest rate premium. If your taxable income understates what the business really earns, lender choice is the whole game. Full detail in our self-employed refinance guide.
Bad credit. Defaults, late payments or an old Part IX agreement do not automatically end the conversation. Specialist lenders price for credit history, and a common strategy is to refinance there, rebuild 12 to 24 months of clean repayment conduct, then refinance again to a mainstream lender once the file has healed. It costs more in the interim, so it only makes sense when the current position is worse, which is often the case for borrowers stuck on a default-rate loan. See refinancing with bad credit for how lenders tier credit events.
