A bank can only offer you its own home loans. A mortgage broker can compare options from the lenders on their panel.
That’s the core difference, but it isn’t the whole decision. How your options are compared, how the loan is structured and the support you get along the way matter too. Neither approach suits everyone, so here’s how each works, what to compare and how to decide.
Key points
- Broker panels vary, so ask which lenders a broker can and can’t access.
- Brokers must act in your best interests, and most are paid by the lender. Any fee must be disclosed before you go ahead.
- Using a broker doesn’t guarantee a lower rate. Compare the overall cost, features and structure, not just the rate.
What’s the difference between a mortgage broker and a bank?
A mortgage broker acts as an intermediary between you and lenders, helping you understand and compare home loan options from the lenders they work with. If you go to a bank directly, you deal with that bank and the home loans it offers.
ASIC’s Moneysmart explains that a broker can help you understand your needs and goals, work out what you can afford to borrow, identify suitable options, explain how different loans work and assist with the application through to settlement.
A broker doesn’t necessarily have access to every lender or home loan in Australia, because lender panels vary. Ask which lenders a broker can and can’t access.
Brokers now arrange most new home loans in Australia. Data commissioned by the Mortgage & Finance Association of Australia shows brokers facilitated a record 81.6% of new residential home loans in the June 2026 quarter.
| Mortgage broker | Bank | |
|---|---|---|
| Lending options | Can consider options from multiple lenders available to the broker. | Offers home loans from its own product range. |
| Comparison | Can compare rates, fees, features, lender policies and structure across available lenders. | You compare options within that bank, or research other lenders yourself. |
| Application | Can help prepare the application and manage the process with the lender. | You deal directly with the bank through the application. |
Costs, features, repayment arrangements and loan structure all affect whether a loan suits you, so the choice isn’t only about lender access. It’s also about how much comparison, guidance and support you want.
What does a broker do that a bank doesn’t?
When you go to a bank, its lending staff assess you for that bank’s products. A broker starts a step earlier. They look at your income, expenses, debts and deposit or equity, compare how different lenders on their panel would treat that position, then manage the application with whichever lender you choose. The lender still makes the final credit decision.
For the full process, from the first conversation through to settlement, see what a mortgage broker does, and when to use one.
What happens when you go directly to a bank?
The bank assesses your application against its own lending policies and considers products from its own range. You deal with the bank throughout the enquiry, application, approval and settlement process.
A bank can explain and assess the loans it offers, but it isn’t comparing them with competing lenders for you. That doesn’t make its option unsuitable. If you want to see how it stacks up on rates, fees, features, policies or structure, you’ll need to make those comparisons yourself or ask a broker to help.
Who does a mortgage broker act for, and how are they paid?
Mortgage brokers in Australia must act in your best interests under the Best Interests Duty, and must put your interests first where there’s a conflict. Most brokers are paid commission by the lender when your loan settles. Some also charge a fee, which must be disclosed before you go ahead. Moneysmart’s guide to using a mortgage broker explains how this works.
Does commission affect which loan a broker recommends?
It can create a potential conflict, which is why the Best Interests Duty and disclosure obligations exist. Being paid by a lender doesn’t remove a broker’s obligation to act in your best interests. You can ask any broker how they’re paid and why they’re recommending one loan over the alternatives.
Does The Finance Architect charge a broker fee?
For standard mortgage broking, we generally don’t charge a broker or service fee and are paid by the lender. In some circumstances a fee may apply where additional work or time is required. If so, we’ll disclose it and agree it with you in advance.
Separate service fees apply to the Blueprint and Accelerator tiers of our Debt-Free Home Strategy, which include additional strategy and ongoing support.
Mortgage broker vs bank: what should you compare?
Look beyond the lowest advertised interest rate.
Choice of lenders. A bank offers its own range. A broker can compare options across their panel.
Lending policies. Lenders assess income, existing debts, deposit or equity and the property differently, so the options available to you can vary.
Rates and fees. Compare the interest rate alongside establishment, ongoing and other applicable fees.
Features and structure. Consider which features you’ll actually use, such as an offset account, redraw facility, fixed or variable rate and repayment options, and how the loan is structured.
Support. Ask who will handle documentation, the application and communication during assessment, and what happens after settlement. Mortgage reviews can help check the loan still suits you.
Can a mortgage broker get you a better interest rate?
Not necessarily. A broker may identify competitive rates across the lenders available to them, but using one doesn’t guarantee a lower rate than going directly to a bank. Fees, features, repayment options and structure all affect the overall cost.
So rather than asking “Who can get me the lowest rate?”, ask “Which home loan offers the right combination of cost, features and structure for my circumstances?”
When does each approach make sense?
Going directly to a bank
It can make sense if you already know which lender or loan you want and feel comfortable judging whether it suits you. For example, you may value an existing banking relationship, want a specific bank product, have straightforward requirements or have already compared alternatives. If you’re comfortable comparing options and managing the process yourself, that may be all the help you need.
Using a mortgage broker
A broker can help whenever you want support understanding and comparing your options, not only when your circumstances are complex.
- First home buyers: borrowing options, lender requirements and the steps before making an offer.
- Next home buyers: an existing mortgage, equity and the timing of buying and selling.
- Refinancing: comparing your current loan with alternatives, and whether to switch, restructure or stay.
- Property investors: loan structure and the effect of one lending decision on future borrowing.
A broker can be particularly useful where lender policies could materially affect your options, such as if you’re self-employed, have multiple debts or loans, or have less straightforward circumstances.
Are you choosing a loan or planning your mortgage?
A home loan needs to do more than get the property financed. Think about the features you’ll use, how the mortgage should be structured, how today’s decisions could affect future property plans, when the loan should be reviewed and where you might reduce debt sooner.
At The Finance Architect, arranging the loan is part of the process, not the end of it. We start with your current position and goals, plan the approach, structure the mortgage around your circumstances, arrange the finance and review it as things change, with the longer-term goal of helping you own sooner. For clients who want to go further, the Debt-Free Home Strategy provides a more structured approach to mortgage strategy and ongoing support.
Whichever route you take, ask how this mortgage fits with where you want to go next.
Questions to ask before choosing a bank or mortgage broker
- Which lenders can this broker access, and which can’t they?
- How are you paid, and will any fee be disclosed in writing before I commit?
- Am I comparing overall cost and structure, or mainly the advertised rate?
- Who will manage the application and communication with the lender?
- What support will I receive after the loan settles?
- How does this mortgage fit with what I may want to do next?
Mortgage broker vs bank FAQs
Is it better to use a mortgage broker or a bank?
Neither is automatically better. A broker can compare options across the lenders available to them, while a bank can only offer its own products. Your choice may come down to how much comparison and support you want, and whether you’re comfortable researching alternatives yourself.
Do I have to use the lender my broker recommends?
No. You decide whether to proceed. A broker should be able to explain why they recommend a loan, and you can ask about the alternatives they considered.
Is it more expensive to use a mortgage broker?
Not necessarily. Brokers are generally paid by lenders, although some also charge a client fee, which should be disclosed in advance. For how we charge, see the fee section above. For how broker payment works, see how mortgage brokers get paid.
Can I speak to a mortgage broker and my bank?
Yes. Speaking to both can show you what your existing bank can offer and how that compares with a broker’s options. Before submitting multiple applications, check whether credit enquiries will be recorded and discuss the implications with the broker or lender.
Can a broker arrange a loan with my current bank?
Yes, if your bank is on the broker’s lending panel. The broker can compare your bank’s options alongside other lenders, and you can still choose to stay where you are. Ask early whether your bank is on their panel.
Is the interest rate the same through a broker as going direct?
Not always. Some lenders offer the same rates and products through both channels. Others have products that are only available direct, or price loans differently through brokers. Compare the overall cost (rate, fees and features), not the channel.
If I go direct now, can I use a broker later?
Yes. Many people go direct for one loan and use a broker later to review or refinance, or the other way around. Neither choice locks you in, although switching lenders can involve costs. See when to refinance your home loan.
Where to start
Whether you use a broker or go directly to a bank, the goal isn’t just to get a loan approved. It’s to compare your options properly and choose a mortgage that suits where you are now and what you want to do next.
