Refinancing Checklist: Five Traps That Still Catch Aussie Borrowers

If you locked in a loan during the low‑rate years or you’ve been hit by multiple rate rises, refinancing can still put real money back in your pocket. But even savvy borrowers get tripped up by a handful of gotchas that only show up at application or settlement. Here are the five traps we still see in 2025 plus a practical 10‑minute checklist to help you avoid them.

1. Cashback & “teaser” rate bait‑and‑switch

Cashbacks and sharp headline rates are tempting, but the fine print matters more:

Revert rates: Some introductory discounts end after 1–3 years, jumping you back to a higher revert rate. The comparison rate is a better guide than the headline rate because it factors in most fees and the revert structure.
Conditional cashbacks: Minimum loan sizes, LVR limits, “new‑to‑bank” rules and occupancy requirements often apply. Some lenders claw back the cashback if you leave inside a set period.
Package fees: Annual package fees can erase a chunk of the savings if the discount is small or short‑lived.

How to protect yourself: Compare by total cost over 3–5 years, not just year one. Ask your broker for a side‑by‑side of comparison rate, revert rate, fees, and any clawback period.

2. Serviceability buffer traps (even when repayments would fall)

Plenty of borrowers assume “I’m paying my loan now, so surely I’ll pass.” Not necessarily. Lenders assess new loans using a buffer above the actual interest rate to test whether you could still afford repayments if rates rise further. That can sink applications where the new rate is lower but the assessed rate is higher than your current one.

Common pinch points:

High assessed expenses or undisclosed discretionary spending.
Credit card/overdraft limits: Lenders assess a deemed repayment on the limit, not your current balance.
BNPL and micro‑loans: These can signal ongoing commitments, reducing capacity.
Short employment tenure or variable income (overtime, commissions, ABN income) that isn’t fully accepted.

Quick levers before you apply:

Reduce or close unused card limits and overdrafts.
Clear BNPL balances and let bank statements reflect the change.
Tighten discretionary spending for 90 days so statements support your declared living costs.
Consider a longer loan term or debt consolidation where appropriate to improve assessed affordability (not advice, get personalised guidance).

3. Valuation shortfalls and the LVR “cliff”

Your home’s bank valuation drives two crucial outcomes: pricing and whether Lenders Mortgage Insurance (LMI) applies. A small valuation shortfall can push your Loan‑to‑Value Ratio (LVR) over key thresholds (commonly 80%), triggering LMI or higher risk‑based pricing.

Why it catches people out:

Lender‑ordered valuations can be more conservative than recent sales or agent appraisals.
Some lenders price sharply at ≤80% LVR, with step‑ups above that.
Renovations that add value don’t always translate 1:1 in a valuer’s report.

What to do:

Ask your broker to pre‑screen valuations or use lenders that allow upfront panel valuations.
If you’re close to 80% LVR, explore options to reduce the loan amount (e.g., tip in savings) or improve the valuation evidence (comparable settled sales, not listings).
Be open to trying a second lender, different panels can yield different outcomes.

4. Fixed‑rate break costs: invisible until you ask

If you’re on a fixed rate and want to refinance (or even vary/repay early), you may face break costs. These are essentially an economic adjustment the lender charges if wholesale rates have moved against them since you fixed.

Key nuances:

Break costs can change week to week and aren’t shown on normal statements.
You can request a formal payout figure that includes them; it’s only valid for a short window.
Sometimes partial breaking (splitting the loan, or waiting until closer to expiry) reduces the hit.
Loan portability isn’t a free pass, moving the fixed loan to a new property can still involve fees and policy checks.

Rule of thumb: Model the savings vs. break cost over the period you’ll realistically keep the new loan. If the payback period is long or uncertain, waiting may be smarter.

5. Exit‑fee surprises and settlement timing

While old‑school “deferred establishment fees” on new home loans were abolished long ago, there are still real exit costs that surprise borrowers:

Discharge/settlement fees from your current lender.
Government registration and mortgage release charges.
Pro‑rata interest if settlement dates slip.
Package fee anniversaries, refinance just after the fee anniversary where possible.
Cashback clawbacks if you exit too early.
Fixed‑rate break costs (see Trap 4).

Timing tips:
Coordinate payout figures and settlement dates carefully. Keep a small buffer for rate movements and daily interest. Confirm what happens to your offset and redraw at discharge, some lenders sweep these balances at settlement if you don’t transfer them out in time.

Your 10‑minute refinancing checklist (2025 edition)

Documents & data (5 minutes):

Latest 6 months of loan statements and your rate/revert schedule.
3 months of transaction/offset statements to verify income/expenses.
Income evidence (most recent payslips, Notice of Assessment, or accountant letter for self‑employed).
Current credit card/overdraft limits and any BNPL accounts.
A quick estimate of property value using recent settled comparable sales.

Decision points (5 minutes):
6. What’s your target LVR? If you’re above 80%, are you comfortable with LMI or do you want to restructure to get under?
7. Are you on a fixed rate? Request a payout with break costs before you proceed.
8. Run a serviceability sense‑check: could you handle a higher assessed rate? If tight, consider reducing limits, consolidating debts, or adjusting the loan term (seek advice).
9. Compare total cost over 3–5 years (rate path + fees + potential cashbacks/clawbacks), not just year one.
10. Line up settlement timing to avoid double fees and to protect offset/redraw balances.
