Split home loan

Split home loans in Perth, part fixed and part variable

Quantum Finance arranges split rate home loans in Perth: one portion of the loan is fixed and the rest stays variable, so you get a repayment you can budget around and keep the offset and extra repayments on the remainder.

  • One loan, split into a fixed portion and a variable portion.
  • A repayment you can budget around on one part, flexibility on the other.
  • The offset and extra repayments stay attached to the variable portion.
  • The ratio set around your budget, not around a rate forecast.

What our split loan service does

The work we do to structure a split properly

A split home loan divides your borrowing into a fixed portion and a variable portion under one loan. Getting it right is a sizing exercise: how much of the repayment must hold still, and how much has to stay free for the offset and extra repayments.

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.

A split is not a hedge on where rates go. It is a way of matching each half of the loan to a different thing your household needs from it.

  • We set the split around your budget, not a forecast

    The fixed portion should cover the part of the repayment your household cannot absorb a rise on. Working backwards from that figure gives you a ratio grounded in your actual budget. Nobody at this business can tell you where rates are going, and the split does not require anyone to.

  • We size the variable portion around what you will pay in

    Extra repayments are usually capped on a fixed loan, and the offset only works against variable borrowing. The variable side needs to be big enough to absorb the money you actually intend to put against the loan. Too small a variable portion makes the split pointless.

  • We compare split policy across 40+ lenders

    Lenders differ on how many splits they allow, whether they charge to create or restructure one, and whether the offset can sit against the variable portion. Two lenders can price a fixed term similarly and administer a split very differently.

  • We explain the break costs on the fixed side

    The fixed portion of a split behaves like any fixed loan: exiting it early triggers a break cost, and selling or refinancing can trigger it. The variable portion is unaffected. Knowing which half of the loan carries the restriction is the point of understanding the structure.

  • We prepare and submit the application

    We put the file together so it lands properly the first time, then submit it to the lender we have chosen. Applications fired off to see what sticks are what damage a credit file, so we assess against policy before anything goes in.

  • We diarise the fixed expiry on the split

    When the fixed portion ends it reverts to a variable rate set by the lender, and the two halves then sit on whatever rates the lender applies. We book the review before that happens, so the revert is a decision rather than something that happens to you.

Ways borrowers split a home loan

Six ways to divide a split loan, and who each one tends to suit

The ratio is the whole decision on a split loan, and there is no default that is right for everybody. Each option below starts from a different question about your household.

An even split

Tends to suit

Borrowers who want the decision to stop being a decision

Worth knowing

Half the repayment is predictable, and half keeps the offset and extra repayments

Weighted to fixed

Tends to suit

Households on a tight budget with little capacity to absorb a rise

Worth knowing

More certainty, and a smaller variable portion for the offset to work against

Weighted to variable

Tends to suit

Borrowers intending to pay the loan down quickly

Worth knowing

Keeps most of the loan free of repayment caps, with a smaller predictable core

Fixed portion sized to the base budget

Tends to suit

Households working backwards from what they must be able to pay

Worth knowing

The most defensible way to choose a ratio, because it uses your figures rather than a forecast

Variable portion sized to the offset balance

Tends to suit

Borrowers holding a genuine cash buffer

Worth knowing

The offset only reduces interest on variable borrowing, so the variable side has to be big enough

Different fixed terms on multiple splits

Tends to suit

Borrowers staggering when the fixed portions expire

Worth knowing

Not every lender allows several splits, and some charge to create or restructure them

Knowing the difference does not hurt. Do not stress about picking a ratio, though — tell us what your budget has to survive and what you intend to pay in, and we work the split out from there.

Who split rate home loans suit

The households we split loans for

A split suits a household that needs certainty on part of the repayment and flexibility on the rest. These are the situations that arrive most often.

  • Households in Perth who want a predictable core repayment without losing the offset

  • Borrowers who intend to pay extra but cannot afford the whole repayment to move

  • Couples where one income is fixed and the other varies with bonus or commission

  • Investors who want part of the holding cost known while keeping cash accessible

  • Borrowers coming off a fixed term who are not confident about fixing everything again

  • Anyone who has been told to fix by one person and stay variable by another

How our home loan process works

Five steps, from the first conversation to settlement

A split loan runs through the same process as every loan we write, with the ratio decided before anything is submitted. Here is the whole thing, start to finish.

  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

  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

    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

About our independent mortgage brokers

The brokers who set your split

Independent means no franchise above us and no lender owning a share of the business. Nobody upstairs sets a monthly target, so the ratio we recommend follows your budget rather than a product push. Your bank splits its own loan; 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 split loan

The ratio is the decision, and it should come from your budget

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 split rate home loans

What is a split home loan?

A split loan divides your borrowing into two portions under one loan: one fixed and one variable. The fixed portion holds its rate for an agreed term, and the variable portion moves with the market while keeping the offset account and unrestricted extra repayments.

What is the best ratio for a split loan?

There is no default that suits everybody. A defensible approach is to fix the portion of the repayment your household could not absorb a rise on, then leave the rest variable. That works backwards from your budget rather than from a view on where rates go.

Can I have an offset account on a split loan?

The offset works against the variable portion, because that is where the interest calculation can be reduced. It does not usually apply to the fixed portion. This is why the variable side needs to be large enough to hold the balance you actually keep.

Do break costs apply to a split loan?

They apply to the fixed portion, in the same way they apply to any fixed loan. Exiting that portion early, selling the property or paying a large lump sum against it can trigger a break cost calculated by the lender. The variable portion is not affected.

Can I split an existing home loan?

Often yes, either with your current lender or as part of a refinance. Lenders differ on whether they charge to create or restructure a split and on how many they allow. It is worth asking rather than assuming your loan has to stay as it was written.

What happens when the fixed portion of my split ends?

That portion reverts to a variable rate set by the lender, and the whole loan then sits on the rates the lender applies at the time. The revert is not automatically competitive. We diarise the expiry so it becomes a decision rather than something that happens to you.

Is a split loan more expensive to run?

Not usually in itself, though some lenders charge a fee to create or restructure a split and some limit how many you can have. The rate on each portion is priced separately. We check the specific lender's terms as part of the comparison rather than after settlement.
