Should you refinance your Sydney home loan in 2026? A 7-step checklist 2026 雪梨房貸 Refinance 7 步檢查表
After two years of falling rates, the RBA reversed course in early 2026 and pushed the cash rate back to 4.35% in May. That changes the refinancing maths for a lot of Sydney homeowners. This is the no-fluff checklist I run through with clients before recommending a refinance — including the new APRA rule that catches some refinancers off guard.
TL;DR · 重點
- Refinancing usually pays back in under 12 months when you're more than 0.3–0.4% above the best market rate for your situation, and you're not breaking a fixed loan.
- Cashback offers ($2,000–$4,000) still exist with some lenders, but they're tied to specific loan amounts and LVR bands — substantiate before banking on them.
- APRA's new DTI ≥6 limit (from Feb 2026) caps how many high-DTI loans each lender can write — refinances where the borrower's DTI is 6x or more are getting tighter scrutiny.
- The 3% serviceability buffer still applies — switching costs nothing if you don't pass servicing, even if your existing repayments are clearly affordable.
- Plan the switch around end of a billing period, not the middle, to avoid double-charges.
The big-picture context for 2026 2026 年的市場背景
Three things worth knowing before you compare offers:
- RBA at 4.35% after a 25bp rise on 6 May 2026, the third recent hike. The market mostly assumes rates have peaked, but several lenders priced rate-cuts in too aggressively in 2025 and are now repricing back up.
- APRA's serviceability buffer remains 3%. Banks must assess you at your loan's rate plus 3% — so on a 6% loan, you're assessed at 9%. That hasn't changed.
- New DTI cap from Feb 2026: lenders can now write only 20% of new mortgage lending at debt-to-income (DTI) of 6 or higher. If your total household debt is 6x or more of household income (very common in Sydney with $1M+ loans), individual lenders are quietly tightening on you to manage their quota.
Translation for refinancers: just because you're already in a loan doesn't mean the new lender will approve you. You have to pass their serviceability assessment as if you're a fresh borrower.
The 7-step checklist 7 步檢查
①What's your current rate, and how does it actually compare?
Pull your last loan statement and find the variable rate (or the fixed rate, plus expiry date). Compare it to the median rate offered by major banks for your LVR band — not the headline rate. If you bought 4–5 years ago at 80% LVR and your place has appreciated, you're likely now at 60–65% LVR and entitled to a sharper tier.
②How much could you actually save?
Rule of thumb: every 0.25% off saves roughly $50/month per $250,000 of loan. So a 0.5% drop on a $900K loan is about $360/month, or $4,300 in year one. Multiply that across the remaining term — but discount for the fact that the rate you're switching to isn't locked forever.
③What does the switch actually cost?
| Cost | Typical range |
|---|---|
| Discharge fee (old lender) | $200–$400 |
| Settlement/legal at new lender | $0–$400 |
| Land registry fees (NSW) | ~$170 release + ~$170 mortgage |
| Application/valuation fee at new lender | $0–$600 (often waived) |
| Fixed-rate break cost (if applicable) | Can be $5K–$25K+ — get a written quote |
Most refinancers I see pay $400–$800 in total when not breaking a fixed loan, and that's typically offset by cashback offers (see step 5).
④Will you actually pass the new lender's servicing test?
This trips up refinancers more than first-time buyers, because incomes plateau and expenses (kids, school fees, additional debts, credit card limits even if unused) keep growing. The new lender will assess you at your new rate + 3%. If your situation has tightened since you took the loan, you may not pass — and there's no point starting the application until we know.
Also a 2026-specific consideration: if your total household debt is 6× household income or more, lenders are quietly more cautious. Specialist non-bank lenders and second-tier banks may still place you when a big-four says no.
⑤Cashback offers — real money, but read the conditions
Some lenders run refinance cashback offers in the $2,000–$4,000 range. They typically require: minimum loan size (often $250K or $500K), a specific LVR band, owner-occupier P&I usually, and the offer applies to the first loan account only when refinancing multiple. They can also be temporary — what's on the table when you start may be gone by settlement. I always confirm the live offer in writing with the lender before you commit.
⑥Are you breaking a fixed rate?
Fixed-rate break costs are calculated against the lender's current wholesale funding cost. When rates have fallen since you fixed, breaking is expensive. When rates have risen, breaking can be cheap or even nil. Always ask your current lender for a written break-cost quote before applying anywhere else — quotes are usually valid for 14 days.
⑦Are you using the refinance to release equity?
If your Sydney property has appreciated and you want to pull equity out (for a renovation, an investment property deposit, or business capital), the structuring matters. Equity for personal use is usually approved at owner-occupier rates if kept under 80% LVR; equity for investment purposes is priced and structured differently. Get this right at application time — restructuring later is messy.
When refinancing usually doesn't pay off 什麼時候不要 Refinance
- You're within 12 months of your loan ending (small savings, full switching cost).
- Your LVR is above 80% and you'd trigger fresh LMI at the new lender.
- You're locked into a fixed rate with a big break cost still to amortise.
- Your situation has tightened and you'd fail the new lender's servicing — better to wait or restructure your current loan.
- You're chasing the cashback alone — once you account for higher headline rates and conditions, you can be net behind.
What to bring to a 30-minute refinance chat 面談需要準備的資料
- Latest loan statement (showing rate, balance, repayment, term).
- Two recent payslips (or last two years' tax returns if self-employed).
- Approximate value of your home — a recent RP Data report or a known recent sale of a comparable next door.
- Rough monthly living expenses, including school fees and any private health.
- Any other debts: credit cards (with limits), personal loans, BNPL, HECS, car finance.
With that I can usually tell you in under 30 minutes whether refinancing makes sense, which 3–5 lenders to compare, and the realistic best rate you'd actually get.
