About our independent brokerage

About our independent mortgage brokers

Independent means no franchise above us and no lender owning a share of the business. Nobody upstairs sets a monthly target, so the shortlist you get is the one your file earns. Your bank offers one loan; we compare 40+.

Gavin Harrigan has been broking from West Leederville since 2005. Today it runs on a small team, Gavin Harrigan, Justin Richardson and Xavier Prescott, each with their qualifications on the page. You deal with the person who writes your loan, before settlement and after it.

The work runs from a first home loan, through refinancing and investment lending, out to construction, small developments and commercial property. Same broker, whichever end of that you are at.

Why choose us?

We answer to you, because there is nobody else to answer to
  • Included

    No franchise, no head office quota

    We do not pay a franchise fee, so nobody upstairs sets a monthly target for us to hit. That removes the main reason a broker recommends the wrong loan.

  • Included

    No lender owns a share of us

    The banks have no stake in this business and no claim on where files go. Your bank has one loan to sell you. We do not.

  • Included

    40+ lenders, one shortlist

    We compare 40+ bank and non-bank lenders, then explain why the shortlist looks the way it does. Policy differences decide more applications than rate does.

  • Included

    We will tell you when the answer is no

    If refinancing does not actually save you money, we say so and you leave the loan where it is. A wrong loan costs more than the fee it earns.

  • Included

    The same broker after settlement

    You keep dealing with the person who wrote the loan. We review it as rates and your circumstances change, not once and then never again.

How our loan process works

Five steps, and you know where you are at every one

Most of the stress in a home loan comes from not knowing what is happening. Here is the whole thing, start to finish, with no surprises kept back for later.

  1. Start an application

    You send us the basics and we work out what you could borrow and which lenders will look favourably at your situation.

    What you need

    Income, debts, deposit

    Read this step in full: Start an application
  2. Get pre-approved

    We put your file to the lender that fits and bring back a pre-approval in writing, subject to lender approval and your circumstances.

    What we do

    Match the lender to your file

    Read this step in full: Get pre-approved
  3. Get officially approved

    Once your offer is accepted, the lender orders its valuation and issues formal approval.

    What we do

    Chase the lender, so you do not have to

    Read this step in full: Get officially approved
  4. Prepare for settlement

    We go through the loan documents with you before you sign anything, then coordinate the lender and your settlement agent.

    What you need

    Your questions, asked early

    Read this step in full: Prepare for settlement
  5. Stay up to date

    After settlement we keep the loan under review as rates move and your circumstances change.

    What we do

    Review it, and tell you first

Mortgage broker FAQs

The questions we get asked before the first meeting

If yours is not here, ring us and ask. Nobody is going to put you on a mailing list for it.

What is an independent mortgage broker?

An independent mortgage broker is not owned by a lender and does not trade under a franchise. There is no head office setting volume targets and no bank with a stake in where files go. We compare 40+ bank and non-bank lenders and recommend the one that suits your circumstances.

How do mortgage brokers get paid?

Brokers are paid a commission by the lender once your loan settles, not by you upfront. Commission is broadly similar across the panel, so it does not decide the recommendation. We disclose what we are paid in writing before you apply, and again in your credit proposal.

Does using a broker cost me anything?

For a standard residential home loan, no. The lender pays the commission at settlement and you pay us nothing. If a file is complex enough to warrant a fee, we tell you the amount in writing before any work starts, so there is never an invoice you did not agree to.

How many lenders do you compare?

We compare 40+ lenders, covering the major banks, second-tier banks and non-bank lenders. Your own bank will only ever offer you your own bank's loan. A wide panel matters most when your situation is not standard, because lender policy decides the answer more often than rate does.

What areas do you cover?

We work right across the Perth metropolitan area from our office in West Leederville, and with Australians living overseas who are buying or refinancing back home. Most of the process runs by phone, email and video call, so where you are makes very little difference to how your file is handled.

What do you need from me to get started?

To start we need identification, recent payslips or business financials, and a picture of your existing debts and living costs. From there we can work out what you could borrow and which lenders suit. If anything is missing, we tell you exactly what to send and why it is needed.

Do you help first home buyers?

Yes, and it is a large part of what we do. That includes low deposit applications and the state and federal schemes you may be eligible for. We explain the deposit, the costs that sit on top of the purchase price, and what each lender will accept, before you start looking.

Can you help if I have already been knocked back?

Often, yes. A decline at one bank is usually a policy problem rather than a problem with you, and another lender may take a completely different view of the same file. Send us the reason you were given, or ring 1300 813 113, and we will tell you honestly where you stand.

Get in touch

Tell us what you are trying to do

Four questions and you are done. A broker reads it, works out what is realistically available to you, and rings you back on the number you give us.

Would rather just talk?

Ringing is quicker than waiting for us to ring you, and you get a broker rather than a queue.

1300 813 113

Tell us what you need

Four details, about twenty seconds. We ask the rest on the call, where you can ask us things back.

An Australian mobile or landline. Overseas? Give us the number you use at home and we will work around the time difference.
