What our fixed rate service does

The work we do before and after you fix

A fixed rate home loan locks your interest rate, and therefore your repayment, for an agreed term. Fixing is a trade rather than a saving, so the work is pricing the options across the panel and making sure you know exactly what the certainty costs you.

Most residential loans are paid for by the lender through commission rather than by you. Where a fee would apply, we tell you before you apply, in writing.

Nobody at this business can tell you where rates are going, and anyone who says otherwise is guessing. What we can do is match the term to what you know about your own circumstances.

  • We compare fixed pricing across 40+ lenders

    Fixed pricing is set independently by each lender and it does not track the variable market in step. Two lenders can sit close on variable and a long way apart on a fixed term. Comparing the panel is the only way to see that, because no single rate card shows it.

  • We explain what fixing takes away

    Extra repayments are usually capped on a fixed loan, offset is not offered by every lender on a fixed portion, and redraw can be restricted. Those limits are the actual cost of certainty. Borrowers who intend to pay the loan down quickly often find fixing works against them.

  • We put the break costs in front of you before you sign

    Exiting a fixed loan early triggers a break cost, and it can be substantial depending on how rates have moved since you fixed. Selling the house, refinancing, or paying a lump sum in can all trigger it. It is calculated by the lender at the time, so the point is knowing it exists before you fix.

  • We check the fixed term against your plans, not the forecast

    The right fixed term is the one that matches what you know about your own life: a job change, a baby, a sale, a renovation. Nobody can tell you where rates go. We match the term to your circumstances rather than to a prediction.

  • We handle the rate lock

    A fixed rate can move between application and settlement, and most lenders offer a rate lock for a fee. Whether it is worth paying depends on the size of the loan and how far out settlement is. We tell you what your lender charges and whether it is worth it in your case.

  • We diarise the expiry rather than leaving it to you

    A fixed loan that reverts unnoticed puts a household on whatever rate the lender applies at the time. We book the review before the term ends, so the revert is a decision rather than something that happens to you.

Work out your fixed repayment

See what the repayment locks at before you commit to it

Fixing is a decision about a monthly figure rather than about a rate. Running the repayment at the rate you are being offered, and again at a higher one, shows you what you are buying protection from.

Who fixed rate home loans suit

The households we fix loans for

Fixing suits a household that values a predictable repayment more than the flexibility to pay the loan down early. These are the situations that arrive most often.

  • Households in Perth on a tight budget who need the repayment to hold still

  • First home buyers who want their first years of ownership to be predictable

  • Borrowers whose income is fixed and cannot absorb a rate rise

  • Investors who want a known holding cost while they build a portfolio

  • Families going down to one income for a period and planning around it

  • Borrowers coming off an existing fixed term who need the revert dealt with

How our home loan process works

Five steps, from the first conversation to settlement

Fixing is a decision made inside the same process every loan we write goes through. 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.

About our independent mortgage brokers

The brokers who price your fixed rate

Independent means no franchise above us and no lender owning a share of the business. Nobody upstairs sets a monthly target, so we are not steering you into a fixed term to hit one. Your bank publishes one fixed rate card; we compare 40+ lenders.

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 for a fixed rate loan

Nobody upstairs benefits from you fixing

Every point below is a consequence of how this business is owned, not a slogan about service.

  • 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.

Common questions about fixed rate home loans

Should I fix my home loan rate?

It depends on whether you value certainty or flexibility more. Fixing protects your repayment from rises but limits extra repayments and carries break costs if you exit early. Many borrowers split the loan and take some of each. We talk it through against your actual budget rather than a forecast.

What are break costs on a fixed rate home loan?

A break cost is what a lender charges if you exit a fixed term early, and it can be substantial depending on how rates have moved since you fixed. Selling, refinancing or paying a large lump sum in can all trigger it. The lender calculates the figure at the time, so ask before you act.

Can I make extra repayments on a fixed rate loan?

Usually only up to a capped amount each year, and the cap is set by the lender. Exceeding it can trigger a break cost. If paying the loan down quickly matters to you, that restriction is the real cost of fixing and it is worth weighing before you commit.

Can I have an offset account on a fixed rate loan?

Some lenders offer an offset against a fixed portion and many do not, so it depends entirely on which lender writes your loan. This is one of the more common reasons borrowers split their loan, keeping a variable portion with the offset attached. We check the policy before recommending a lender.

What happens when my fixed rate ends?

The loan reverts to a variable rate set by the lender, and that revert rate is the loan you actually end up with. It is not automatically competitive, which is why the expiry is worth diarising. We book the review before the term ends so the revert is a decision rather than something that happens to you.

Is a rate lock worth paying for?

A rate lock holds the fixed rate you have been quoted between application and settlement, and most lenders charge a fee for it. Whether it is worth paying depends on the size of your loan and how far out settlement is. We tell you what your lender charges and whether it stacks up in your case.

Can I fix only part of my loan?

Yes, and it is a common approach. Splitting the loan means one portion is fixed and one stays variable, so you get certainty on part of the repayment and keep the offset and extra repayments on the rest. It is a way of not having to pick one side of the argument.
