Stay or Switch? How to Win a Sharper Home Loan Rate

You don’t have to accept the rate your bank gives you. If your home loan rate is clearly above what a new customer would pay, you can usually either negotiate a sharper deal with your current lender (repricing) or refinance to another bank. The smartest move is to benchmark your rate, push your bank for a discount, and only switch if the extra savings comfortably outweigh the costs and hassle over the next few years.

This guide walks you through that decision in plain English, so you can take concrete steps this week.

Start by benchmarking your current rate against realistic new‑customer deals.

1. Stay or switch? The quick answer

In most cases, you should try to reprice with your current lender first, then consider refinancing if:

• Your current rate is ~0.50–1.00 percentage point or more above sharp new‑customer rates for a similar borrower; and
• Your bank won’t match (or get close to) a realistic competitor quote; and
• A simple breakeven calculation shows you recover all switching costs in around 2–3 years or less.

Repricing is usually faster, involves less paperwork and avoids fresh serviceability assessment under APRA’s 3% buffer. Refinancing takes more effort and scrutiny, but can unlock bigger savings, better features or a more flexible structure.

If you’re not sure whether your current rate is uncompetitive, start with this simple framework and then come back to this guide to plan your next move.

2. Step 1 – Check if you’re paying a ‘loyalty tax’

2.1 What is the mortgage loyalty tax?

Banks often give their sharpest rates to new customers and quietly let existing borrowers drift up over time. That gap is your loyalty tax – you’re effectively paying extra for staying put and not asking questions.

You might be paying a loyalty tax if:

• Your rate is 0.50–1.00%+ higher than the best deals available for similar borrowers; or
• Your fixed rate recently ended and you’ve been rolled onto a high revert rate; or
• You haven’t reviewed or renegotiated your loan in 2–3 years.

Roy Morgan data shows more than a quarter of Australian mortgage holders are now ‘At Risk’ of mortgage stress, largely due to higher rates. Keeping even a 0.50% loyalty tax when you don’t need to is money straight out of your pocket.

2.2 How to benchmark your rate in 15–20 minutes

You don’t need a perfect comparison, just a realistic benchmark for someone like you (owner‑occupier vs investor, P&I vs IO, similar LVR).

1. Grab your latest statement

   • Note: current rate, remaining balance, remaining term, repayment type, fixed vs variable, and your approximate property value.

2. Work out your LVR (loan‑to‑value ratio)

   • Example: Loan $640,000 / Property value $800,000 = 80% LVR.
   • At 80% or lower, you normally avoid LMI and unlock sharper pricing.

3. Check realistic new‑customer rates

   • Look at 3–4 major banks and a couple of smaller lenders.
   • Filter for your situation: e.g. owner‑occupied, P&I, 60–80% LVR.

4. Compare the gap

   • If your rate is around 0.50–0.70% higher than competitive offers, it’s worth a serious repricing request.
   • If the gap is 1.00%+, you’re almost certainly overpaying and should be ready to move if your bank won’t sharpen.

For a deeper sense check, see the specific checks in /insights/how-to-tell-if-your-home-loan-rate-is-uncompetitive-2026.

2.3 What’s a 0.50% or 1.00% gap worth?

On a $700,000 loan over 25 years, P&I:

• At 6.5%, repayments are about $4,728 per month.
• At 6.0%, repayments fall to about $4,492 per month.
• That’s a saving of ~$236 per month, or ~$2,832 per year.

Drop by 1.0% instead (6.5% → 5.5%) and the annual interest saving is well north of $5,000, especially early in the loan when the balance is higher. Small rate cuts are meaningful on big balances.

3. Step 2 – Repricing: negotiating with your current lender

Repricing means your current lender reduces the margin they’re charging above their reference rate, without changing lender or doing a full new application. It’s often the quickest way to cut your repayments.

3.1 When repricing usually works best

Your bank is more likely to play ball if:

• Your LVR is 80% or less (or at least improved since you first borrowed).
• Repayments have been on time for the last 6–12 months.
• Your income is stable and your overall debt hasn’t blown out.
• You’re not mid‑fix; you’re on a variable or a fixed rate close to expiry.

For self‑employed borrowers with clean conduct and improving numbers, this is exactly the playbook in /insights/negotiating-current-lender-self-employed.

3.2 What to prepare before you call

Spend 30–60 minutes getting your case ready:

• Current rate & loan details – from your statement or online banking.
• Estimated property value – from a recent appraisal or online estimate.
• Your LVR – loan ÷ value.
• Competitor examples – 2–3 real rates from banks willing to lend to someone like you.
• Your ask – a specific rate, not just “a better deal”.

Example of a clear ask:

“I’m currently paying 6.59% on a $640,000 owner‑occupier P&I loan at around 80% LVR. I can see other banks offering around 5.89% for similar borrowers. I’d like you to match 5.89% or come as close as you reasonably can.”

3.3 How to run the repricing call

1. Call your lender and choose the “existing home loan” or “I’m thinking of leaving” option.
2. Tell them calmly you’re reviewing your options and want to check if they can offer a better rate to keep your business.
3. Give them:
   • Your current rate, balance and LVR.
   • The specific competitor rates you’ve found.
   • Your clear request for a lower rate.
4. Ask to speak with the retention or pricing team (they often have more discretion than frontline staff).

Sample script:

“I value the relationship, but my rate isn’t competitive. I’m seeing 5.89% for loans like mine. If you can’t get close, I’ll have to refinance. Can you please review my pricing with the retention team?”

3.4 What outcome to accept – and when to walk

After 1–2 business days, you’ll usually get an answer. Assess it like this:

• Good outcome: They cut your rate to within 0.10–0.20% of the realistic alternatives, with no new fees. Staying put is often sensible.
• Average outcome: They shave 0.10–0.30% but still sit 0.40–0.70% above good competitors. That’s a sign you should run refinance numbers.
• Poor outcome: They refuse to move, or only reduce by 0.05–0.10% when you’re clearly uncompetitive. Time to explore other lenders.

Remember: repricing will not change your loan features, structure or term. If you need better splits, offset access, or to restructure home vs investment debt, that’s a separate conversation and often points towards refinancing.

4. Step 3 – When refinancing beats staying put

Repricing is the low‑friction first step. Refinancing is the bigger move where you switch lenders entirely, sign a new contract and go through full serviceability assessment.

4.1 Situations where refinancing usually makes sense

Refinancing is worth a close look when:

• Your bank won’t come close to competitive rates, and the gap is 0.75–1.00%+.
• Your current loan doesn’t offer features you now need (offset, extra splits, better portability, more flexible IO options for investors).
• You’re consolidating other debts or restructuring home vs investment borrowing.
• You’re coming off a fixed rate onto a very high revert rate and the bank won’t sharpen it.

The full strategic lens is covered in /insights/when-why-refinance-home-investment-loan-australia. Here we’ll focus on the stay vs switch maths.

4.2 The breakeven calculation (with worked example)

Any refinance comes with costs: discharge fees, registration fees, possibly break costs and new LMI. The key is to work out how long it takes for interest savings to cover those costs.

A practical rule, also discussed in /insights/real-costs-of-refinancing-break-fees-lmi-gotchas, is:

Breakeven period (years) = Total refinancing costs ÷ Annual interest savings

Example – Should you refinance?

• Current loan: $700,000, 24 years remaining, rate 6.50%.
• New loan: $700,000, 24 years remaining, rate 5.70%.
• Indicative total refinancing costs: $2,000 (government, discharge, application – excluding any cashback).

Approximate annual interest saving in year one:

• At 6.50%, interest in year one ≈ $45,000.
• At 5.70%, interest in year one ≈ $39,900.
• Saving ≈ $5,100 in the first year.

Breakeven:

• $2,000 ÷ $5,100 ≈ 0.39 years, or ~5 months.

If you expect to keep this loan for more than a year or two, that refinance is likely worthwhile – provided you don’t reset back to a fresh 30‑year term, which would increase total interest over the life of the loan, even at a lower rate.

4.3 Serviceability and risk: the APRA buffer

Refinancing means a brand‑new credit assessment. Lenders must test your ability to repay at an assessment rate at least 3 percentage points above the actual rate, in line with APRA guidance.

• If the new loan rate is 5.70%, they will usually test you at around 8.70%.
• This can be very tight for borrowers whose income has dropped, or who have taken on extra debts.

If your circumstances have changed or your income is complex, refinancing might be harder than it looks on a simple calculator – another reason to try repricing first.

5. Repricing vs refinancing: side‑by‑side comparison

Here’s how the two options usually stack up in practice.

Repricing and refinancing each have different costs, risks and benefits.

The right move depends on how far off‑market your rate is, how long you plan to keep the property and how easy it will be to pass a fresh assessment.

6. Special cases: investors, self‑employed and small business owners

6.1 Property investors

For investors, the decision isn’t just about today’s cashflow – it’s about after‑tax outcomes and flexibility.

Consider:

• Interest‑only vs P&I: IO often improves short‑term cashflow but increases total interest over the life of the loan and can face higher rates.
• Deductibility: Investment loan interest is usually deductible, but that doesn’t mean you should ignore an uncompetitive rate.
• Multiple properties: Sometimes it’s smart to reprice a couple of loans where the lender is competitive, and refinance only the outliers.

A broker with tax literacy can help you avoid accidentally mixing deductible and non‑deductible debt in a way that’s expensive to unwind later.

6.2 Self‑employed borrowers

Self‑employed borrowers face two extra challenges:

1. Lenders often assess them using more conservative income and the same 3%+ serviceability buffer.
2. Many ended up in more expensive alt‑doc or specialist products when their financials weren’t yet strong.

If your business performance has improved and your documentation is now stronger, you may be able to:

• Reprice your current alt‑doc or specialist loan to sharpen the rate; or
• Refinance into a mainstream full‑doc product with lower pricing once you meet their criteria.

The step‑by‑step playbook in /insights/negotiating-current-lender-self-employed shows how to build a persuasive case with BAS, bank statements and up‑to‑date financials.

6.3 Small business owners with multiple debts

If you run a small business, lenders don’t just look at your personal payslip; they look at the whole business picture – tax compliance, existing business loans, and how exposed you’d be if revenue dropped. /insights/how-lenders-really-view-your-small-business-home-loan explains this in more depth.

In practice, that means:

• Repricing may be easier because it avoids a fresh, full look at your business.
• Refinancing can still be worth it, but you need a clean story and strong documentation.

For these borrowers, a two‑stage strategy can work well: negotiate the best possible rate with your current lender now, then plan a refinance to an even sharper structure once your next set of financials is lodged.

7. Using a broker so you don’t do this alone

You can absolutely call your bank yourself. But if you’re busy, juggling kids or running a business, there’s a real cost to spending hours on hold, filling forms and comparing products.

A good broker can:

• Benchmark your current rate across a wide lender panel.
• Negotiate with your existing bank on your behalf, using real market data.
• Run repricing vs refinance scenarios, including tax and structure considerations.
• Coordinate the refinance process end‑to‑end if switching is the right call.

See /insights/how-brokers-improve-rates-products-lenders and /insights/benefits-using-mortgage-broker-australia for practical examples of how this works – especially useful if you have multiple properties or complex income.

A good broker can negotiate with your bank and compare refinance options for you.

8. A simple one‑week action plan

If you want to act on this now, here’s a realistic plan for the next seven days.

Day 1–2: Get your numbers and benchmark

• Download your latest loan statement.
• Estimate your property value and calculate your LVR.
• Check current market rates for borrowers like you.
• Note the target rate you’d be happy with.

Day 3–4: Call your current lender

• Call the bank and ask for a rate review or the retention team.
• Present your case: LVR, conduct, competitor rates, and your clear ask.
• Get the outcome in writing via email or secure message.

If the rate you’re offered is within 0.10–0.20% of good alternatives, you may decide to stop here and enjoy the savings.

Day 5–6: If needed, explore refinancing

If your bank won’t play ball:

• List your total estimated refinance costs (ask a broker or check lenders’ fee schedules).
• Get 1–3 realistic refinance quotes.
• Run a simple breakeven: costs ÷ first‑year savings.
• Check whether extending your term will increase total interest and whether that’s acceptable or needs correcting via higher repayments.

Day 7: Decide and commit

• If repricing is good enough, lock it in and diarise another review in 12 months.
• If refinancing wins on both maths and structure, start the application process while your motivation is high.

You don’t need to optimise every last basis point. You just need a materially better deal that supports your cashflow and long‑term goals.

FAQs

1. How often should I review and renegotiate my home loan rate?

In the current rate environment, aim to review your home loan at least once a year or after any major RBA cash rate move. You don’t have to refinance every time, but checking that your rate is still within about 0.20–0.30% of sharp new‑customer deals is sensible. If it isn’t, ask your lender for a pricing review or talk to a broker.

2. Can negotiating my rate hurt my credit score?

Simply asking your own bank for a repricing or retention discount does not usually involve a new credit enquiry and shouldn’t affect your score. A full refinance application with a new lender will typically trigger a credit check, but one well‑considered application is unlikely to cause problems by itself. The real risk comes from multiple applications in a short time.

3. Is it ever better to pay a slightly higher rate and not refinance?

Yes. If the breakeven period on a refinance is very long – say five years or more – and you expect to move, sell or significantly restructure your borrowing sooner, staying put can be rational. It can also make sense to avoid refinancing if your income is uncertain or your situation is about to change, making a fresh serviceability assessment risky.

4. Should I always extend back to a 30‑year term when I refinance?

No. Extending back to 30 years will probably reduce your monthly repayments but increase total interest over the life of the loan, even at a lower rate. Where possible, match the new loan term to your existing remaining term, or plan to make higher repayments so you stay on track. The right approach depends on your cashflow, goals and tolerance for risk.

5. What if my property has fallen in value and my LVR is now above 80%?

If your LVR has climbed above 80%, refinancing can be harder and may involve new LMI, which often kills the benefit. In that case, focus first on repricing with your current lender, improving your conduct and reducing your balance. Once your LVR drops back towards 80%, you’ll generally unlock sharper pricing and more lender options again.

Key takeaways

• Start by checking whether you’re paying a loyalty tax – if you’re 0.50–1.00%+ above realistic new‑customer rates, you should act.
• Repricing with your current lender is usually the fastest, lowest‑friction way to cut your rate and doesn’t always require a full reassessment.
• Refinancing can deliver bigger savings and better structure, but you must pass a fresh serviceability test and recover all switching costs within a reasonable time.
• Use a simple breakeven calculation and avoid unnecessarily extending your loan term when you refinance.
• A broker who understands both tax and lending rules can help you compare options, negotiate with your bank and only switch when the numbers clearly stack up.
