# Mortgage broker vs bank: which is better for your home loan?

**In short:** A mortgage broker compares loans from a panel of many lenders and is legally required to act in your best interests; a bank sells only its own products and owes you no such duty. Both usually cost you nothing and the loan is with a lender either way. A bank can win if you already hold a well-priced package; a broker wins for choice, negotiation and anything outside the ordinary.

The majority of new home loans in Australia are now written through brokers, but that does not make a broker the right answer for every borrower. This guide lays the two options side by side, shows where each genuinely wins, and works through two Melbourne examples.

## Broker vs bank at a glance

| | Mortgage broker | Going direct to a bank |
|---|---|---|
| Choice of lenders | A panel of many lenders: major banks, mutuals, non-banks, specialists | One lender, its own products only |
| Best Interests Duty | Yes. Required by law since 2021 to put your interests first | No. Bank staff must only ensure a loan is "not unsuitable" |
| Cost to you | Usually none; the lender pays commission | None; staff are salaried |
| Rates | Same products as direct; brokers often access pricing discounts and can negotiate below the advertised rate | Advertised rate, plus whatever you negotiate yourself |
| Time and paperwork | Broker collects documents, completes applications, chases the lender | You complete each application yourself, one lender at a time |
| Pre-approval speed | Broker chooses the lender with the fastest current turnaround | Depends on that bank's queue this week |
| Specialist scenarios (self-employed, visa holders, SMSF, low doc, construction, credit impairment) | Broker matches you to lenders with the right policy | Only if that bank's policy happens to fit |
| Ongoing reviews | Trail commission gives the broker a reason to keep you well priced | Loyalty is rarely rewarded; existing customers often pay more than new ones |
| Dispute resolution | AFCA, plus the broker's own complaints process | AFCA, plus the bank's own complaints process |
| Who the loan is with | The lender. The broker arranges it, the lender funds it | The lender |

The last row is worth pausing on. Whether you use a broker or not, your mortgage is a contract with a lender and your repayments go to that lender. A broker chooses and negotiates it with you, then stays on as your point of contact.

## When a bank might be better

Three situations favour walking into your own bank.

### You already hold a well-priced package

If you have an existing professional package with a strong negotiated discount, wealth-tier pricing, or a linked business banking relationship, your bank may already be giving you close to the best deal available. Even then, a broker's rate review across other lenders is the easiest way to confirm it.

### You want one specific bank product

Occasionally a bank runs a product no broker can access, such as a limited-release offer, or you are dead set on a particular lender. A very simple file (PAYG income, 20% deposit, clean credit) with a fixed target is quick either way.

### Employee benefits

Bank employees and some large-employer schemes get discounted rates and waived fees on the bank's own loans. Compare it against the broker's best offer, but do not ignore it.

## When a broker is better

For most other borrowers, and for anyone whose situation has a wrinkle in it, a broker is the stronger option.

- **You want the market compared, not one menu.** A broker can put five lenders' policies and pricing side by side in one sitting.
- **Your income is not straightforward.** Self-employed, casual, contract, commission-based or overseas income. Bank policies differ enormously here. See our [self-employed loans](/services/self-employed-loans/) page.
- **You are a first-home buyer using a government scheme.** Not every lender participates in the First Home Guarantee. Our [first home buyer loans](/services/first-home-buyer-loans/) service is built around this.
- **A bank has already said no.** A decline at one lender is usually a policy mismatch, not a verdict on you.
- **You want someone in your corner after settlement.** A broker's trail income depends on keeping you happy and well priced.
- **You would rather not do the paperwork.** The broker prepares the application, packages the documents and chases the lender's credit team.

## Worked example one: a Werribee first-home-buyer couple

Priya and Daniel want to buy a $620,000 house in Werribee with a 5% deposit under the First Home Guarantee. Daniel is a full-time PAYG nurse. Priya has been in a casual warehouse role for eight months, working consistent 35-hour weeks. Their own bank requires 12 months in a casual role before the income counts. Without Priya's income the couple cannot service a $589,000 loan, so the bank declines.

A broker looks at the same file and knows two lenders on the panel that accept casual income after six months where the hours are consistent. The broker chooses the one with the faster turnaround and a competitive first-home-buyer rate, submits year-to-date payslips, an employer letter confirming ongoing hours and three months of bank statements, and gets pre-approval within days. Under the First Home Guarantee they pay no LMI on the 95% loan, and on a $620,000 first home they also receive a partial stamp-duty concession.

Same couple, same income, same house. The difference was knowing whose policy fitted. A [Werribee mortgage broker](/mortgage-broker/werribee/) sees this pattern every week.

## Worked example two: an Epping refinancer and the loyalty tax

Sanjay has a $650,000 home loan in Epping taken out four years ago. His variable rate is, for illustration, 6.25% p.a., so he pays $4,002 a month, while the same bank advertises 6.00% to new customers. He asks a broker for a rate review, and the broker runs two tracks at once.

| Option | Rate (illustration) | Monthly repayment | Saving vs today |
|---|---|---|---|
| Stay as he is | 6.25% | $4,002 | Nil |
| Retention discount from current bank after the broker's request | 6.00% | $3,897 | $105 a month, $1,260 a year |
| Refinance to a competing lender on the broker's panel | 5.75% | $3,793 | $209 a month, $2,508 a year |

The retention request alone saves Sanjay $1,260 a year with no paperwork, no valuation and no change of lender. The refinance saves twice that but involves discharge and application fees and a few weeks of process. The broker's job is to show him both and let him decide; our [refinance calculator](/calculators/refinance/) does the same sums for your loan. Note what Sanjay's bank did not do: it never called him in four years to offer the lower rate, because bank staff have no duty to. A broker earning trail on his loan has every reason to. Our [Epping mortgage broker](/mortgage-broker/epping/) page covers what we see in the northern suburbs.

## How to choose a broker

Not all brokers are the same. Use these tests.

- **Ask for the Credit Guide before anything else.** It shows the licensee, aggregator, commission ranges and top lenders by volume. Ours is at [credit guide](/credit-guide/). If you cannot get one, keep looking.
- **Ask which lenders they actually use.** A large panel is only useful if the broker knows the policies inside it.
- **Ask about experience with your scenario.** A broker who mainly writes vanilla PAYG loans may not suit a self-employed or SMSF file.
- **Ask what happens after settlement.** Annual reviews should be standard, not a favour.
- **Look for local knowledge.** A broker who knows Melbourne's growth corridors understands valuation risk in new estates and which lenders are cautious about particular postcodes.
- **Check language and communication.** GNT Finance works in English, Nepali and Hindi, and a large part of our client base is Melbourne's Nepali and South Asian community. Our [Nepali mortgage broker Melbourne](/nepali-mortgage-broker-melbourne/) page explains how that works.
- **Understand how they are paid.** Our guide on [how mortgage brokers get paid](/guides/how-mortgage-brokers-get-paid/) covers upfront, trail and clawback so nothing is a surprise.

Gorakh Timilsina, who founded GNT Finance, began as a broker assistant, moved into lending as a senior credit officer assessing applications from the other side of the desk, then returned to broking as a senior mortgage consultant. That inside-the-bank experience is what you want when the question is which lender's credit team will say yes to this file.

## Broker vs bank checklist

Before you decide where to apply, work through this list.

- Have you asked your current bank for its best rate in writing, so a broker has a number to beat?
- Do you have any income that is casual, contract, self-employed, overseas or less than 12 months old?
- Are you using the First Home Guarantee, Help to Buy or a stamp-duty concession, and does your bank participate?
- Do you need pre-approval by a specific date, such as before an auction? Our [home loan pre-approval](/guides/home-loan-pre-approval/) guide explains timing.
- Have you compared the comparison rate and fees, not just the headline rate?
- Have you read the broker's Credit Guide and confirmed there is no fee to you?
- Do you know who to contact after settlement for a rate review?

## Common mistakes

- **Going to your own bank only.** Existing customers routinely pay more than new ones, and the bank has no duty to point that out.
- **Assuming a broker costs money.** For a standard home loan the lender pays the broker. Any fee must be disclosed in writing before you proceed.
- **Not checking the Credit Guide.** It is the fastest way to see how a broker is paid and who they usually place loans with.
- **Treating one decline as final.** Lender policies on casual income, visa status, self-employment and credit history vary widely. A decline at one is not a decline everywhere.
- **Applying to several lenders yourself to "see who says yes".** Each application is a credit enquiry. A broker assesses your file against policy first and submits to one lender.

## Frequently asked questions

### Is it better to use a mortgage broker or go to the bank?

For most borrowers a broker is the better starting point: the same products at the same or better pricing, a comparison across many lenders, and a legal Best Interests Duty that bank staff do not owe you. A bank can be the better choice if you already hold a strongly discounted package, want a product only that bank offers, or have employee pricing. Even then, a broker's review costs nothing and confirms you are not overpaying.

### Do mortgage brokers get better rates than banks?

Brokers offer the same products at the same advertised rates as the bank itself, so the rate is never worse. In practice brokers often secure pricing below the advertised rate, because lenders give brokers access to discretionary discounts and because a broker can play lenders off against each other on your behalf. The bigger saving usually comes from choosing the right lender in the first place rather than squeezing a few points from one.

### Are mortgage brokers free?

For standard home loans, usually yes. The lender pays the broker an upfront and trail commission, so there is no cost to you for the service in most cases. A fee can apply for complex commercial, SMSF, very small or short-term loans, and it must be disclosed in writing before you commit. The commission does not add to your interest rate or fees; it comes out of the lender's own distribution budget.

### Can a mortgage broker get me a loan when the bank said no?

Often, yes. Most declines are policy mismatches rather than a judgement that you cannot afford the loan: casual income under 12 months, self-employed income with one year of returns, a visa condition, an old small default, or a postcode the bank restricts. A broker knows which lenders on the panel accept those circumstances and can place the same file with one of them. A decline for genuine affordability is different, and a good broker will say so.

### Does using a broker affect my credit score?

Using a broker does not itself touch your credit file. What affects your score is the number of formal credit enquiries, and this is where a broker helps: rather than you applying to three banks and collecting three enquiries, the broker assesses your file against each lender's policy first and lodges one application with the lender most likely to approve. Some lenders offer a soft-check pre-assessment that does not appear on your file.

### What is the disadvantage of using a mortgage broker?

A broker can only recommend lenders on their aggregator's panel, so a product from a lender outside it will not be offered, and broker quality varies, so choosing a poor one wastes time. Broker-lodged applications can also sit in a separate queue at some banks. You manage these by choosing a broker with a broad panel, a clear Credit Guide and specific experience with your type of loan.
