What does a mortgage broker do?
What does a mortgage broker do? If you haven’t purchased a home before, this question is probably on your mind.
Buying a place to live in is one of the biggest financial decisions most people make in their lives, and the mortgage process can feel complex, opaque and stressful. A mortgage broker acts as an intermediary between borrowers and banks or lenders, helping clients navigate loan options, assess borrowing capacity, and make informed decisions about their finances.
In simple terms, a mortgage broker is a licensed professional who works on behalf of borrowers to research, assess, negotiate and manage home loan solutions.
In practice, the role goes far beyond comparing interest rates or submitting a loan application. A high-performing broker supports clients through the entire mortgage application process, from early planning through to settlement and beyond.
This article from The Property Education Company explains what a mortgage broker does, how brokers are paid, what obligations they have to clients and what separates an average broker from a high-performing one.
In short:
- Mortgage brokers help people to apply for new home loans and refinance their existing ones
- They have in-depth knowledge of the home buying process and act as guides to help their clients make decisions
- Mortgage brokers are governed by strict regulations in Australia
- At The Property Education Company, we are an education-first mortgage broker firm that is committed to long-term client relationships
The rise of mortgage brokers in Australia
Over the past two decades, mortgage brokers have become a central part of the Australian lending market. Today, a significant majority of home loans are written through brokers rather than directly through a bank branch. In fact, 77.3% of all new residential lending in Australia was facilitated by mortgage brokers in the September 2025 quarter.
There are several reasons for this.
First, the lending market has become more complex.
- Borrowers now face a wide range of loan products, loan features, mortgage terms and eligibility rules.
- Different lenders assess income, expenses, assets, credit history and borrowing power in different ways.
For most borrowers, understanding how multiple lenders operate is difficult without professional support. And the risks of getting things wrong are high, including rejected applications and loans which cost more than they need to.
Second, many banks have reduced their face-to-face advisory services. While online tools and call centres have expanded, fewer borrowers receive personalised guidance inside a local branch. Mortgage brokers fill this gap by providing tailored advice and explaining the home-buying process in plain language. They can also introduce their clients to a number of different loans, rather than restricting them to one lender.
Third, regulation has increased. Changes following the Royal Commission into the banking, superannuation and financial services industry placed stronger obligations on lenders and brokers alike. While this added compliance and paperwork, it also raised professional standards and clarified that brokers must act in the best interests of their clients.
As a result, many borrowers now choose to work with a mortgage broker who can assess the market, explain loan options and support them through the application process, rather than dealing with a single bank in isolation.
What does a mortgage broker do?
A step by step explanation
When people ask what does a mortgage broker do?, they are often thinking about the loan application itself. In reality, a broker’s work begins well before an application is submitted and continues long after settlement.
Below is a step-by-step look at how a mortgage broker typically supports clients.
Initial conversation and understanding your situation
The first step is always a conversation. Your broker will take the time to understand your financial situation, your life stage and your financial goals. This includes discussing:
- Income and employment structure
- Existing loans, including car loans and personal finance
- Expenses and living costs
- Assets and savings
- Credit history
- Short and long-term plans, such as upgrading, refinancing, or future property purchases
This stage is about context. A broker goes beyond numbers to help you look at how your money fits into your life and what you are trying to achieve.

Assessing borrowing capacity and borrowing power
Using detailed assessment tools, a broker calculates your borrowing capacity and borrowing power across different lenders. This is a critical step because each bank and lender assesses risk differently.
Two borrowers with the same income may receive very different loan application outcomes depending on the lender, the loan terms and how expenses are assessed. A broker’s role is to identify which lenders are most likely to suit your situation and provide realistic guidance on what you can borrow and what you should borrow.
Researching loan options across multiple lenders
A mortgage broker is not limited to recommending a single lender. Brokers research loan options across multiple lenders, including major banks, regional banks, and specialist lenders.
This research considers more than interest rates. Your broker will research:
- Loan products and mortgage options
- Loan features such as offset accounts and redraw facilities
- Fees and ongoing cost
- Flexibility around repayments and future changes
- Policy rules that may affect approval
The goal is to narrow the field to the loan options that suit your financial situation and long-term goals, not simply the lowest advertised rate.
Explaining options and supporting informed decisions
Once suitable loan options are identified, a broker explains the differences in plain language. This includes walking through mortgage terms, interest structures, repayment types, and potential trade-offs.
This is where tailored advice matters. Your broker will help you compare loan options side by side so you can decide with confidence. The aim is not to push a single product, but to help you make an informed decision that fits your needs.
Managing the loan application process
After you decide to proceed, your broker manages the loan application process on your behalf by submitting your application to the lender you have chosen. This includes:
- Preparing and submitting the loan application
- Gathering and checking documentation
- Coordinating with lenders and assessors
- Responding to questions and requests for further details
This stage involves significant paperwork and attention to detail. A broker’s experience helps reduce errors, delays and unnecessary stress during the application process. As the home buyer, you will usually only have a main point of contact, but there is often a team of several people working behind the scenes to support you.
Negotiation with lenders
Mortgage brokers also negotiate with lenders where necessary. This may involve negotiating interest rates, fees or specific loan terms.
Because brokers work with different lenders regularly, they understand how to present an application clearly and how to position a borrower’s strengths. This negotiation role is a key benefit for many clients.
Your broker can also liaise with your lender to discuss refinancing options after you have had your loan for a few years.

Approval, settlement and follow-up support
Once home loan approval is issued, your broker continues to support you through settlement. They often liaise with the lender, conveyancer and other parties to ensure the process runs smoothly.
After settlement, a dependable broker remains involved. This may include reviewing your loan over time, discussing refinance options, or helping you manage changes in your financial situation.
Staying up to date with the industry
An important but often unseen part of what a mortgage broker does is staying informed.
The lending market changes constantly. Interest rates move, policies shift and lenders adjust their ‘appetite’ for different types of borrowers.
Brokers maintain ongoing relationships with lenders, attend industry briefings, review policy updates and engage in continuous professional development. This effort allows us to provide current, relevant advice and access suitable loan products as the market evolves.
Staying up to date often feels like a full-time job in itself, but brokers take this responsibility very seriously.
Maintaining relationships
Brokers have a circle of contacts outside of clients. We work with bank representatives including loan assessors and business development managers, and we have a network of real estate agents, buyers agents, property valuers, property inspectors and conveyancers who we stay connected with to share information and refer clients.
Our networks help us to deliver more value to our clients, so we see keeping in touch is an important part of our job.
How is a mortgage broker paid?
A common question borrowers ask is how mortgage brokers get paid and whether there is a cost to the client.
In most cases, mortgage brokers are paid a commission by the lender once a loan settles. This payment does not usually increase the interest rate or fees you pay compared to going directly to a bank. The lender pays the broker for originating and managing the loan.
In some situations, a broker may charge a fee. This can occur when:
- The loan amount is very small relative to the work involved
- The loan structure is particularly complex
- The broker knows the loan will not remain in place long enough for them to be paid
Any fees should be disclosed clearly before you proceed, so you can decide whether the cost and benefit make sense for your situation.

Your broker’s obligations to you
Mortgage brokers in Australia operate under a strict regulatory framework. They are required to act in the best interests of their clients, not the lender.
This includes obligations to:
- Act honestly and fairly
- Provide recommendations that suit your financial situation and goals
- Explain why a particular loan is appropriate
- Avoid conflicts of interest
- Maintain appropriate licensing and professional standards
These obligations are designed to protect borrowers and ensure brokers act as genuine intermediaries rather than salespeople for banks.
Brokers are legally required to avoid terms such as ‘best’, ‘guarantee’ and even ‘advice’ in order to comply with strict regulatory and consumer protection laws, avoid misleading or absolute claims, and ensure recommendations are framed as information tailored to an individual’s circumstances rather than promises or financial guarantees.
At The Property Education Company, we work with a legal team to ensure our communications meet these requirements, and aim to apply ethics and best practices in all our endeavours.
What makes a high-performing broker?
Not all brokers offer the same level of service. A high-performing broker stands out in several ways.
Look for a broker who can prove to you that they:
- Invest time in understanding clients and keeping them informed.
- Communicate clearly and regularly.
- Manage the mortgage application process with care and attention to detail.
- Maintain strong lender relationships while always prioritising the client’s best interests.
Some brokers provide ongoing support beyond a one-off service. This may include loan reviews, assistance when clients’ circumstances change, and guidance on future property or finance decisions. This long-term service approach is reflected in client feedback and repeat business, noting that individual experiences may vary.
Case Study: Location can affect borrowing in ways some buyers may not expect. Lenders often categorise postcodes by risk, and in this case the property was located just outside a metro boundary. The Property Education Company team prepared supporting information relating to the property, its location and the buyer’s circumstances for the lender’s consideration. The lender ultimately agreed to proceed, noting that outcomes depend on individual circumstances and lender policy at the time.

Mortgage Broker Services: FAQs
What does a mortgage broker do compared to a bank?
A broker works on behalf of borrowers and can access multiple lenders to facilitate home loans, while a bank does the actual lending. So a mortgage broker cannot ‘give’ you a home loan, they can only help you to arrange one, by sharing their expertise and liaising with lenders on your behalf.
Does using a broker cost more money than going direct to a bank?
In most cases, no. Brokers are typically paid by the lender, and loan costs are comparable to going direct. If fees apply, they must be explained in detail.
Can a broker help with refinance?
Yes. Brokers regularly assist clients to refinance when their financial situation or the market changes by liaising with existing or new lenders.
Do mortgage brokers help with credit history issues?
A broker can assess your credit history, explain how it affects your options, and identify lenders whose policies may suit your situation. They may be able to share tips to help you improve your current credit status.
Are brokers regulated in Australia?
Yes. Mortgage brokers are licensed professionals with clear obligations to act in their clients’ best interests. Read more about mortgage broker best interest duty here.
