Picture this. You’ve bought a home, and over the past 4 years managed to picked up two Investment Properties (IP’s) – and you’re feeling pretty darn good about your adulting milestones. But then… *insert ominous noise here*… you decide to sell your home to upgrade… and 2 days before settlement, come to find out that the 2 IP’s are using equity in your home (the one you’re trying to sell) and now you’re going to be $100k short of funds for your new purchase (the bigger, better home you’re moving into). At this point, both the sale (of your old place) and purchase (of your new home) are contractually locked in, and you’re now unable to settle without selling a kidney.
Why do I give you this grim story? Because it’s legit true. Happened to a broker mate of mine (his client) a little while back, and it’s always stuck with me as the biggest reason to make sure your structure is set up in a way that will protect you from exactly this type of horrendous situation.
Between evolving tax laws, rising property markets, and the everyday nightmare of keeping your personal finances sorted (watch this video to see why I recently took at look at my own finances), how your loans are set up matters more than you might think. It’s not – and never has been – just about getting a low interest rate.
Our expert brokers Tristina and Simone see it all the time. Clients come to us with good intentions, but their loans are lumped together like a bowl of tangled Christmas lights. And trust me, your accountant will charge you more if you ask him to untangle your Christmas lights at tax time.
Let me break it down and show you how to fix your setup before things get messy.
Separate Loan Splits For Separate Purposes
Imagine walking into a chaotic kitchen where all the utensils, spices, and cleaning supplies are thrown into one giant drawer (actually, that’s basically my kitchen). Good luck finding the teaspoon when you are rushing to make your morning mocha-almond-cappa-flat-long-black-macchiato.
Your loans work the same way. If you mix your tax deductible debt (like an investment property loan, share portfolio funding or funds used for business purposes) with your non deductible debt (your owner occupier home loan or personal car loan), you create a compliance nightmare for your accountant.
Smart loan structuring means creating clean, distinct loan splits for every single purpose:
- Your Home Loan: Strictly quarantined as non deductible debt.
- Your Investment Property: Kept on its own separate loan split.
- Your Share Portfolio: Tied to its own dedicated facility if you are borrowing to invest in shares.
- Your Car Purchase: Even if you release equity from your property for a new vehicle, seasoned brokers like Tris and Simone will often recommend setting up a smaller, separate loan split with a shorter loan term so you are not dragging a car loan out over 30 years.
Keeping things separate means clear paper trails, happy accountants, and zero guesswork when tax season rolls around.
The Offset Account Masterclass
If you have an offset account linked to your investment loan, we need to talk.
Here is the golden rule of offset accounts: attach them exclusively to your non deductible debt.
(Obviously if you’re legendary enough to have paid off your non deductible debt, offset whatever you want)
Your owner occupier home loan is the ultimate target here. Every dollar sitting in an offset account linked to your home loan reduces the interest you pay on debt that the tax man won’t let you write off.
Smart Repayment Strategies For Maximum Flow
Let us talk about cash flow. One of the most effective strategies in our toolkit is setting up investment loans as interest only. Why? Because you want to minimise the cash tied up in paying down deductible investment principal, leaving you with maximum breathing room in your budget.
Where does that spare cash flow go? More uber eats of course! Kidding. That extra cash flow goes straight into aggressively paying down your non deductible owner occupier debt.
You pay off the bad debt (the house you live in) faster while keeping the good debt (the investment asset building your long term wealth) managed efficiently.
I’ll give you an example to show you some real numbers.
Same person (let’s call them YOU), 2 different structures:
Your position:
- $500k owner occupied (home loan) debt
- $1M investment debt
- $200k savings
Scenario A:
- You’ve got $200k in a high interest savings account earning 5%. ****
- Your home loan is P&I 6% with 25 years remaining
- Your investment loan is P&I, 6.5%, 30 years remaining.
Scenario B:
- You’ve got $200k parked in an offset account, linked to your $500k home loan
- Your home loan is P&I 6% with 25 years remaining (same as Scenario A)
- Your investment loan is IO, 6.7%
If you’re on 30c tax bracket, Scenario B saves you $13,190 over a 3 year period and your home loan is paid off 12.75 years sooner (this assumes that all parameters above remain the same).
If you’re on 47c tax bracket, Scenario B saves you $20,346 over a 3 year period and your home loan is also still paid off 12.75 years sooner.
That is a MASSIVE difference, and you didn’t have to spend a dollar more. You just needed to fix your loan structure. Pretty cool huh?
The above are approximates and is illustrative only – it’s not tax advice. I’ll get into trouble if I start giving out tax advice, so please run this past your accountant and see what they reckon.
Navigating The Tax Landscape
Under current rules, established residential properties purchased from 1 July 2026 face strict negative gearing adjustments. If you are buying an established property under the newer guidelines, standard negative gearing benefits won’t automatically apply against your ordinary wage or business income the way they used to.
What does this mean for your loan structure? It means blanket strategies no longer work.
- You need to look closely at whether an established property or a brand new build fits your portfolio goals.
- Your loan setup needs to be tailored precisely to your income bracket, your expected capital growth, and your holding timeline.
- Relying on generic, cookie cutter loan products is a fast track to financial frustration.
This is where having an experienced broker in your corner is non negotiable. We keep track of the complex policy changes so you can focus on building a resilient, future proof portfolio.
Avoiding The Danger Of Cross Collateralisation
Picture this. You own your home and an investment property. Because you used the same bank for both, they tied them together using cross collateralisation.
Then, one local property market dips slightly. You want to buy your next property or pull equity out for a renovation, but your bank says no because your assets are locked in a messy web – or think back to the Christmas lights story at the beginning of this blog.
Smart loan structuring means keeping every property standalone. Each asset stands on its own two feet, with each loan secured to one property only. That way, a market movement in suburb A does not hold you hostage when opportunities arise in suburb B. It gives you more flexibility to do what you want, with your portfolio, without letting the banks push you around.
Time To Lock In Your Strategy
Loan structuring is not a glamorous dinner party topic – unless of course you begin by saying – holy shamoley batman, we just paid off our home loan 12.75 years earlier because of a few tweaks to our home loan structure! Then you can bask in the glow of how wonderful it feels to be better than your dinner guests because you’re so whiz bang savvy.
To find out what your structure is, you can spend 4 hours going back and forth with ChatGPT, only to come to the end of your chat realising your robot friend may have smoked a big fattie, so you fact check it in Claude, then Gemini and none of them agree with each other, you get so frustrated that you wasted an entire Saturday afternoon that you hit the bottle early and pass out on the couch in a drunken rage – or… you could ask us.
