The real cost of not using a strategic mortgage broker
Did you know the right mortgage broker can save you five or six figures over the life of your loan?
The Reserve Bank lifted the cash rate to 4.85% on 4 November 2026, its fifth rise this year and the highest level since 2008 (ABC). With rates this high, even a small interest-rate difference adds up fast, and so does a poorly structured loan.
A strategic broker looks beyond the rate to how your loan is structured, how it will support your next property move, and how it affects your tax position.
We've run three common scenarios to show what that difference looks like in dollars.
What’s the difference between a mortgage broker and a strategic mortgage broker?
A mortgage broker finds you the right loan for today, while a strategic mortgage broker structures that loan around where you want to be in the years ahead.
A traditional broker usually focuses on the property you're buying now: how much you can borrow, which lender offers a competitive rate, and getting you to settlement.
A strategic broker asks about your next 5 to 10 years first, such as whether you'll upgrade or keep your home as an investment, and sets up the loan with those plans in mind.
That might mean keeping savings in an offset so the debt stays tax-deductible later, splitting personal and investment loans, or choosing a lender that will still lend to you for your next purchase.
What you get | Going direct to your bank | Transactional broker | Strategic mortgage broker |
Lenders compared | One | Many | Many |
Focus | Rigid; the bank must follow its own policies for assessing income and expenses. | Access to multiple lenders and can match you with the right lender to maximise your borrowing capacity | Access to multiple lenders and can match you with the right lender to maximise borrowing capacity and strategy for current and future decisions |
Loan structure advice | Limited or none | Basic | Offsets, splits and future investment planned in |
Tax-aware set-up | Rarely | Sometimes | Built in, with your accountant |
Ongoing rate reviews | Only if you ask | Varies | Proactive and regular |
Next property planned for | No | Rarely | Yes |
Legal duty to act in your best interests | No | Yes | Yes |
Since 1 January 2021, Australian mortgage brokers have been legally required to act in your best interests under the National Consumer Credit Protection Act 2009, a change introduced after the Hayne Royal Commission (ASIC). Bank staff must meet responsible lending rules, but they aren't bound by the same best interests duty.
Scenario 1: How much can a strategic mortgage broker save a first home buyer?
A 0.50% rate difference on an $800,000 loan saves about $95,000 in interest over 30 years.
Imagine a couple buying their first home with a $800,000 loan over 30 years. Their own bank offers them 6.84%. A strategic broker compares the market and secures 6.34% with a lender whose policy suits their income.
Bank direct (6.84%) | Strategic broker (6.34%) | Difference | |
Monthly repayment | $5,237 | $4,973 | $264 less |
Saving per year | $3,168 | ||
Savings over 5 years | $15,840 | ||
Total interest over 30 years | $1,085,225 | $990,158 | $95,040 saved |
The biggest savings come from keeping repayments the same. If the couple keep paying the $4,973 a month they would have paid their bank, the extra $264 goes straight off the loan, and they clear it almost four years early.
Repayment approach | Loan paid off in | Total interest | Saving |
Bank rate, minimum repayments | 30 years | $1,085,225 | |
Broker rate, same repayment as bank | 26 years | $835,510 | $154,648 |
A strategic broker will also set up an offset account from day one, so every dollar saved reduces interest without locking you into the loan.
Scenario 2: How much can refinancing with a strategic mortgage broker save you?
A borrower who hasn't reviewed their loan in years could be overpaying by more than $5,000 a year.
Imagine a couple who took out their home loan seven years ago. They have $750,000 left to repay over 25 years. Their rate has crept up to 7.24% while their bank offers new customers far less. This gap is often called the loyalty tax.
Their strategic broker refinances them to 6.34% with a lender that suits their situation.
Staying put (7.24%) | After refinancing (6.34%) | Difference | |
Monthly repayment | $5,416 | $4,989 | $427 less |
Saving per year | $5,124 | ||
Savings over 5 years | $25,620 | ||
Total interest over 25 years | $874,886 | $746,798 | $128,088 saved |
Refinancing is not free, so here is the honest cost side. Fees vary by lender and state, but a typical switch looks like this.
Cost of switching | Approximate amount |
Discharge fee from the old lender | $350 |
Government mortgage registration and discharge fees | $250 |
New lender application and valuation fees | Often $0 |
Annual package fee* | $96 to $395 a year, usually replacing a similar fee you already pay |
Total | About $600 |
* This comparison assumes you already pay an annual package fee with your current lender. Package fees with major and preferred lenders range from $96 to $395 a year, so switching usually swaps one fee for another rather than adding a new cost.
At $427 a month in savings, the couple recover their switching costs in under two months. Some lenders also offer cashback deals that cover these costs entirely, and a strategic broker will weigh those against the long-term rate.
Scenario 3: How can a strategic mortgage broker help property investors save on tax?
The same rate, set up two different ways, can save over $24,000 in tax over ten years.
Imagine a couple with a $500,000 home loan and $100,000 in savings. In a few years, they plan to upgrade and keep this home as an investment property.
A transactional approach puts the $100,000 straight onto the loan to cut interest.
A strategic broker keeps the savings in an offset account instead. Today, both options save the same amount in interest. The difference appears when the home becomes an investment.
Savings paid into the loan | Savings kept in an offset | |
Interest saved while living there | Same | Same |
Loan balance when it becomes an investment | $400,000 | $500,000 |
Tax-deductible debt | $400,000 | $500,000 |
$100,000 savings | Gone | Free to use as a deposit on the new home |
Extra deductible interest per year (at 6.20%) | $6,200 | |
Extra tax saving per year (39% marginal rate incl. Medicare levy) | $2,418 | |
Extra tax saving over 10 years | $24,180 |
This example is illustrative only and is not tax advice. The figures are based on assumptions about interest rates, loan balances and marginal tax rates, and your actual outcome will depend on your circumstances. Tax rules can change, so speak with a registered tax agent or accountant before structuring your loan for tax purposes.
Once you pay a loan and redraw it, the ATO generally looks at what you use the money for, not where it came from. That means redrawing it for the new home does not make it deductible. This one decision, made years earlier, can't be undone later.
Other structural moves a strategic broker considers include:
Splitting loans so investment and personal debt never mix
Choosing interest-only or principal and interest to suit your cash flow and tax plan
Protecting your borrowing capacity for the next purchase
Tax outcomes depend on your circumstances, so we always recommend confirming your structure with your accountant.
Frequently asked questions about strategic mortgage brokers
What does a strategic mortgage broker cost?
For most borrowers, nothing. Lenders pay brokers a commission once your loan settles. At PPA, our strategic mortgage advice is included in the service.
Will I pay a higher interest rate if I use a broker?
No. Lenders pay brokers a commission from their own margin, because the broker has done much of the work the lender would otherwise do in-house: assessing your situation, liaising with you, preparing the application and gathering your documents. The commission isn’t added to your rate, so you get the same rates as going direct, and often access to lenders and policies you couldn’t find on your own.
Will a broker just recommend the lender that pays them the most?
No. Most lenders pay brokers a similar commission, so there’s little reason to favour one over another. Where commissions do differ, the lenders that pay more tend to be specialist lenders, which only suit borrowers with credit issues or tight borrowing capacity. For a doctor with high income and a clean credit history, the right lender comes down to policy: how they treat your overtime, salary packaging, LVR and registration. Brokers in Australia are also legally required to act in your best interests, which means recommending the loan that suits you, not the one that pays them the most.
Are there any other costs I should know about?
If you refinance, your old lender and the state government charge discharge and registration fees, usually around $600. Some lenders offer cashback deals that cover these. Many home loans with an offset account also come with an annual package fee, typically $96 to $395 a year with major and preferred lenders. If you’re already on a package with your current lender, you’re usually swapping one fee for a similar one rather than adding a new cost. It’s always worth asking your broker upfront whether any fee applies to your situation.
How much could a strategic mortgage broker save me?
It depends on your loan and goals. In our scenarios, a first home buyer saved $95,040 in interest, a refinancer saved $5,061 in the first year, and a future investor gained $24,180 in tax savings over ten years.
It takes one conversation to find out if you’re paying too much. Book a free chat with our team, and we’ll do the comparing for you.
Scenario | Cost to you | Potential saving |
First home buyer | $0 broker fee | $70,078 in interest, or $172,977 by keeping repayments the same |
Loyal borrower refinancing | About $600 in switching costs | $5,061 in year one, $127,488 over the loan |
Future investor | $0 broker fee | $24,180 in extra tax savings over 10 years |
How often should I have my home loan reviewed?
At least once a year, when a fixed rate is ending or your income changes. A strategic broker will prompt these reviews rather than waiting for you to ask.
When should I speak to a strategic mortgage broker?
Ideally before you start looking at property. Planning your structure and borrowing capacity early gives you the most options and helps you avoid mistakes that are hard to undo later.
It’s also worth getting in touch before a big life change, such as starting a family, changing jobs, going part-time or moving into private practice. These can affect what you can borrow, so it pays to plan ahead.
And if you already have a home loan but have never spoken to a broker, now is a good time. A home loan health check will show you whether your rate, structure and features still suit you. Get in touch to organise yours.
