The 10 Most Common Reasons to Refinance
| # | Reason | What It Achieves | Typical Saving/Benefit | When It Makes Sense |
|---|---|---|---|---|
| 1 | Lower interest rate | Reduces monthly repayments and total interest paid | $1,500–$6,000+/year | Rate gap >0.3% after accounting for switching costs |
| 2 | Cash-out equity | Access funds for renovation, investment, or debt | Avoids 12–18% personal loan rates | LVR below 80%; have a clear purpose for funds |
| 3 | Debt consolidation | Combines credit cards, car loan, personal loan into mortgage | $500–$1,500/month in repayments | High-rate debts; LVR allows absorption; discipline to close cards |
| 4 | Fixed rate expiry | Avoid rolling to SVR; secure new competitive rate | $3,000–$12,000/year vs SVR | Any time fixed rate expires — start 90 days before |
| 5 | Access offset account | Use savings to reduce interest without locking funds away | $2,000–$10,000+/year if large offset balance | Have $30,000+ in savings; current loan lacks offset |
| 6 | Remove borrower | Separation, divorce, or co-buyer exit | Clean financial separation | Relationship breakdown; one party keeping property |
| 7 | Change lender | Dissatisfied with service, fees, or product features | Better features + possible rate improvement | Regular fee increases; poor service; need better redraw/offset |
| 8 | Fund renovation | Cash-out to improve property at home loan rates | Save 6–12% vs personal loan rate | Enough equity; clear renovation plan; adds property value |
| 9 | Reduce loan term | Pay off mortgage faster; save total interest | Tens of thousands over loan life | Income increased; can afford higher repayments; close to retirement |
| 10 | Release guarantor | Remove parent or family guarantor from loan | Protects guarantor's financial position | LVR below 80% via repayments and/or property growth |
Reason 1: Lower Rate — The Most Common Motivation
The most common reason Australians refinance is simply paying too much. Loyal borrowers on 3–5 year old loans are often paying 0.5–1.5% above what's available in the market. On a $600,000 loan, 1% excess rate costs $6,000 per year.
Reason 4: Fixed Rate Expiry — The Most Urgent
When a fixed rate expires and rolls to SVR, many borrowers face an immediate rate increase of 1–2%. This is the single most urgent reason to refinance — the 90-day review window before expiry is critical. A borrower who does nothing can easily pay $6,000–$12,000 more per year.
Reason 5: Access to Offset Account — Underrated Benefit
An offset account is a transaction account linked to your mortgage — every dollar in the account reduces the balance you're charged interest on. If you have $80,000 in savings, an offset account on a $600,000 loan at 6.3% saves approximately $5,040/year in interest. Many borrowers switch lenders purely to access a quality offset account.
Reason 9: Reduce Loan Term
Refinancing provides an opportunity to shorten your loan term. Moving from 25 remaining years to 20 years increases your repayment but dramatically reduces total interest paid.
$600,000 at 6.3% over 20 years: total interest = $464,800
Saving: $135,600 in interest by switching to 20-year term
Monthly repayment increase: ~$490
Reason 10: Releasing a Guarantor
When parents or family members provided a guarantee to help a first home buyer purchase, they remain financially exposed until the guarantee is released. Once the property has grown in value (LVR below 80%), the borrower can refinance to a new lender or apply to have the guarantee formally released. This is an important milestone that many borrowers delay unnecessarily.
