Seven Refinancing Myths That Are Costing Australian Homeowners Money

You and your neighbour have the same loan size and bought at the same time. They’re paying $400 less a month. The difference is that they refinanced eight months ago. If you’ve been putting it off because you think it’s too complicated, that your credit isn’t good enough, or that the savings won’t outweigh the costs, there’s a good chance one of these seven myths is the reason. Here’s what the data actually says, and what each misconception may be costing you.

Why the Refinancing Decision Has Never Been More Consequential

The RBA has raised the cash rate three consecutive times in 2026, moving from 3.60% to 4.35% as of May 5, fully reversing last year’s easing cycle and pushing variable repayments higher with each decision.^1 Against that backdrop, Australians refinanced a record $65.8 billion in home loans during the September 2025 quarter, according to ABS Lending Indicators.^2 That equates to nearly $500,000 in mortgages changing lenders every minute — and with the RBA signalling rates may now be on hold while it monitors inflation, the window for reviewing your loan is open.

The volume tells you borrowers are paying attention. What it doesn’t tell you is how many are making the right call. Some refinance when the numbers don’t support it. Others stay put while losing money every month. The difference between those two outcomes usually comes down to one thing: which of the following myths they believe.

If you’d like to know whether switching makes sense for your loan before going through the full process, book a free refinancing review and we’ll run the numbers first.

Myth 1: Refinancing Always Saves Money

The dangerous version of this myth isn’t that refinancing saves money. It often does. The dangerous version is the assumption that it always does, and that any rate reduction is automatically worth pursuing.

Cost Factor	Typical Range	When It Applies
Discharge fees	$150 to $600	Charged by your current lender when closing the loan. Varies by lender and is subject to change.
Break costs (fixed loans)	$1,000 to $15,000+	Applies when exiting a fixed-rate loan before the term ends. Calculated on the interest rate differential and remaining term.
Establishment fees	$0 to $700	New lender charges. Many competitive products waive this to attract refinancers.
Valuation fees	$0 to $350	Some lenders use desktop valuations at no cost. Others require a physical inspection.
Lenders Mortgage Insurance (LMI)	$2,000 to $15,000+	Applies if your Loan-to-Value Ratio (LVR) exceeds 80% on the new loan.

Consider a homeowner with a $500,000 loan at 5.8% considering a switch to a 5.4% product. Annual interest saving: $2,000. Upfront costs: approximately $900 in discharge and establishment fees. Break-even point: 5.4 months. That’s a straightforward win. Now consider a borrower with a 3-year fixed loan at 4.2%, facing $8,500 in break costs to access current variable rates. Annual interest increase: $6,000. Break costs: $8,500. Net position: significantly worse in year one. ASIC’s MoneySmart guidance on refinancing cautions borrowers to calculate total costs before switching, noting that many borrowers focus on headline rates while overlooking fees that erode potential savings.^3

The rule: refinancing makes financial sense when the net present value of future savings exceeds total switching costs. For loans with break costs exceeding 12 months of the interest differential, waiting until the fixed term concludes is usually the better call.

Myth 2: You Need Perfect Credit to Refinance

Australia uses comprehensive credit reporting (CCR), which captures both positive and negative credit behaviour. What matters more than a perfect score is demonstrating current repayment capacity. Lenders look at consistent employment history, stable verified income, a debt-to-income ratio within their thresholds (typically 40 to 50%), and a genuine savings pattern.

A borrower with a paid utility default from 18 months ago but strong current income and 30% equity can access competitive refinancing. A borrower with a perfect credit history but a recent move to commission-only income may face more hurdles. Six months of consistent savings and stable employment frequently outweigh minor historical credit events in a lender’s overall assessment.

Myth 3: It’s Too Complicated and Time-Consuming

Modern digital refinancing typically involves around 30 to 45 minutes for an initial consultation, a document upload via secure portal, one property valuation (often desktop-based), and a 30-minute settlement appointment. Total active time: roughly two to three hours spread over four to six weeks.

For a $600,000 loan, a 0.5% rate differential represents $3,000 annually. Spending three hours to secure that saving returns an effective $1,000 per hour. Mortgage brokers facilitated 76.7% of all new Australian residential home loans in the December 2025 quarter, the highest broker market share recorded in any December quarter on record.^4 Broker-assisted refinancing in particular has become streamlined, with much of the process handled on your behalf.

Myth 4: Your Current Lender Will Match Any Competitor’s Offer

Lenders occasionally match competitor rates for customers they consider high value. This isn’t systematic. ASIC’s MoneySmart guidance advises borrowers to ask their current lender for a better deal as a first step, but explicitly notes that new customers are often offered better deals than existing borrowers.^3

Following the February 2026 RBA rate increase, several major lenders were advertising competitive rates and cashback incentives for new customers while existing customers contacting retention departments received materially less favourable offers. Without a concrete competitor offer in writing, retention teams have limited internal incentive to match. Always secure a written competitor offer first. A broker with access to 30-plus lenders can generate those comparisons without requiring you to do the legwork.

Myth 5: Refinancing Resets Your Entire Loan Term

Refinancing does not force you onto a new 30-year term. You have complete control. A borrower five years into a 30-year loan can refinance and request a 25-year term to maintain their original payoff date, or a 20-year term to accelerate it while still capturing the rate saving. You can also continue making your existing repayment amount on a new lower-rate loan, which reduces the principal faster without extending the debt. The critical step is stating your preference explicitly during the application process. Lenders accommodate these requests routinely.

Myth 6: Only Worthwhile If Rates Drop Significantly

Rate differentials are one dimension of refinancing value, not the only one.

Benefit Category	Example	Quantifiable Value
Rate reduction	0.4% reduction on $600,000 loan	$2,400 annual interest saving
Feature improvement	Adding a 100% offset account	Effective tax-free return on savings balance at your loan rate
Cashback offers	$2,000 to $4,000 promotional incentives	Direct offset against switching costs in year one
Debt consolidation	Rolling $30,000 credit card debt at 19% into mortgage at 5.5%	$4,050 annual interest saving
Serviceability improvement	Switching to a lender with more favourable income assessment	Unlocks borrowing capacity for future investment

A borrower refinancing from 5.45% to 5.35% might dismiss a 10 basis point difference. But adding a full offset account where they hold $40,000 in savings delivers an effective 5.35% tax-free return on that balance, worth $2,140 annually. Combined with a $2,500 cashback offer, the total first-year benefit exceeds $4,700 despite minimal rate movement. Refinancing is worth evaluating through a multi-dimensional lens, not just as a rate comparison.

Myth 7: You Need 20% Equity to Refinance

While 80% LVR is a meaningful threshold (above it, LMI applies), refinancing remains possible with lower equity. Most lenders permit refinancing at 80 to 90% LVR with LMI capitalised into the loan. Specialist lenders offer products to 90 to 95% LVR at higher interest rates. Refinancing with LMI also differs from purchasing with LMI: you’re transferring existing debt, not increasing it, which many lenders view as lower risk than new lending.

That said, factor LMI costs explicitly into the break-even calculation. Refinancing at 85% LVR with $10,000 in LMI added to a $500,000 loan increases your debt to $510,000, adding approximately $550 annually in interest. For a marginal rate improvement, waiting until you reach 80% LVR is often the better financial outcome.

When Refinancing Makes Sense and When It Doesn’t

Refinancing warrants serious consideration when any of these conditions apply: the rate differential exceeds 0.35% after accounting for all costs and your planned ownership period; loan features are significantly misaligned with your needs; serviceability constraints are blocking future financial goals; you’re carrying high-interest non-mortgage debt above 8%; your fixed term expires within six months with better variable rates available; or your lender relationship has deteriorated.

It typically doesn’t make sense when break costs exceed 18 months of interest savings, you plan to sell within 12 months, your loan carries grandfathered features unavailable in the current market, LMI would erode the net benefit, or a serviceability assessment would fail under APRA’s current 3% buffer requirement.^5 The goal isn’t to refinance frequently. It’s to refinance when genuine value exists and the numbers support it.

One timing consideration worth noting: with the RBA signalling it now has room to pause and monitor economic conditions, borrowers coming off fixed terms in the next six to twelve months face a distinct decision. If rates hold or ease from here, locking back into a fixed product at current levels carries its own risk. A broker can model the break-even across fixed and variable scenarios for your specific loan before you commit either way.

Borrowers with Variable or Commission-Based Income

If your income includes variable components such as bonuses, commissions, allowances, or irregular contracting payments, lender selection matters more than it does for a standard PAYG applicant. Different lenders assess variable income components very differently. Some apply a 50% shading to bonuses and allowances. Others accept 100% of consistent variable income with appropriate documentation.

This difference has real consequences for borrowing capacity and refinancing access. A FIFO worker in Western Australia earning $140,000 base plus $30,000 in consistent annual site allowances could see their assessed borrowing capacity increase by $65,000 simply by refinancing to a lender with a more favourable income assessment policy. That shift in capacity can be the difference between accessing a competitive rate now versus waiting another two years. This applies equally to commission-based salespeople, self-employed contractors, and business owners nationally.

If your income structure is non-standard, work with a broker who can match you to lenders whose assessment policies actually reflect how you earn. A generic refinancing approach, going directly to a major bank, will often undervalue variable income components and leave you with a worse outcome than a specialist can achieve.

Your Refinancing Evaluation Roadmap

Weeks 1 to 2: Position audit. Obtain your current loan statement. Calculate your LVR using a current property estimate. List features you actively use versus those you pay for but ignore. Note any borrowing objectives within the next 24 months.

Weeks 3 to 4: Market research. Use comparison platforms (Canstar, Finder, Mozo) to identify three competitive products matching your profile. Contact your current lender’s retention team with written competitor offers in hand. Calculate total switching costs and your break-even point: total costs divided by monthly interest saving.

Weeks 5 to 8: Professional assessment. Engage a mortgage broker for a full market scan across 30-plus lenders. Request a net benefit comparison that covers features, not just rate. Verify serviceability under APRA’s current 3% buffer. Confirm there are no hidden restrictions on the target product.

Weeks 9 to 12: Decision. Break-even under 12 months and features align: proceed. Break-even 12 to 24 months: proceed only if you’re confident you’ll stay in the property beyond the break-even point. Break-even over 24 months or serviceability is marginal: hold and reassess in six months. On approval, maintain your current repayment amount to accelerate principal reduction on the lower rate.

Frequently Asked Questions

How long does refinancing typically take in Australia?

Most refinances complete within four to six weeks from application to settlement. Broker-assisted refinances often move faster due to direct lender relationships and streamlined document collection. Your responsiveness providing documentation is usually the main variable.

Will refinancing hurt my credit score?

A single mortgage credit inquiry typically reduces your score by five to ten points temporarily. Multiple inquiries within a 45-day window for the same loan purpose count as a single inquiry under Australian comprehensive credit reporting rules. Your score generally recovers within three to six months with consistent repayment behaviour.

Can I refinance if I’m self-employed?

Yes, though documentation requirements differ. Most lenders require two years of personal tax returns plus current financials. Some specialist lenders accept 12 months of BAS statements for established businesses. Lender selection is particularly important for self-employed borrowers, which is where broker access to a wider panel of lenders adds real value.

What happens to my redraw balance when I refinance?

Redraw balances transfer as part of your total loan amount, but redraw functionality depends on the new loan product. Always confirm availability, minimum redraw amounts, and any fees before proceeding. Offset accounts generally provide more flexible access to funds than redraw facilities.

Can I access equity for renovations when refinancing?

Yes. This is called a cash-out refinance. You can typically access equity up to 80% LVR without LMI, or up to 90 to 95% LVR with LMI capitalised. Renovations that increase property value may support a higher LVR if the improved valuation supports the additional debt. Obtain renovation quotes before applying to demonstrate the purpose clearly to the lender.

What if my valuation comes in lower than expected?

A lower valuation increases your LVR, which may trigger LMI or cause serviceability issues. Options include: proceeding with LMI capitalised into the loan; reducing the loan amount to maintain your target LVR; requesting a second valuation if the first appears inaccurate; or delaying the refinance until conditions improve. A broker can model the financial impact of each option before you decide.
