Simple hacks to grow a property portfolio in Queensland

Investment loans work differently from home loans in ways that matter to your deposit and tax return

An investment loan is designed for purchasing property you intend to rent out, not live in. Lenders assess your income, your existing commitments, and the expected rental return from the property you're buying. Interest on the loan is deductible against your rental income and other earnings, which changes the way you think about repayments compared to an owner-occupied mortgage. Your deposit requirement is usually higher, and the rate you're offered will typically sit above what you'd pay on your own home, but those extra costs buy you access to features that matter when you're building a portfolio rather than a place to live.

Consider a buyer looking at a unit in Sippy Downs with a purchase price at the current median of around $740,000. With a 20 per cent deposit of $148,000, they'd borrow $592,000. At current variable rates for investment lending and with interest-only repayments, the loan might cost around $3,100 per month. Rental income from a unit in that suburb typically sits at $640 per week, or roughly $2,770 per month. After rates, insurance, and management fees, the shortfall might be $600 to $700 per month. That shortfall is negatively geared and deductible against the buyer's salary, reducing their taxable income. The property itself sits near the University of the Sunshine Coast, where tenant demand from students and hospital staff keeps the vacancy rate on the Sunshine Coast at 0.7 per cent, one of the lowest in Queensland.

The loan structure you choose at the outset shapes how much flexibility you'll have when you go to buy a second property. Most first-time investors lock in a single variable rate and move on. That works until you want to refinance part of the loan or access equity without touching the whole balance. Splitting your loan into two or three separate accounts under the one security lets you fix part of the debt, keep part variable, and later redraw or refinance one portion without recalculating the entire loan. It also keeps your paperwork cleaner if you're planning to use equity from this property as a deposit on the next one.

Interest-only repayments lower your monthly cost and keep equity available for your next deposit

Interest-only means you're not paying down the loan balance during the interest-only period, which can run for one to five years depending on the lender. Your repayment covers interest charges only, so your monthly outgoing is lower than it would be on a principal-and-interest loan of the same size. The benefit is cash flow. You can hold more in your offset, service the loan more comfortably while building rental history, and keep equity in the property available to borrow against when you're ready to purchase again.

As an example, a $600,000 loan at an investment variable rate on interest-only terms might cost around $3,150 per month. The same loan on principal-and-interest terms would sit closer to $4,000 per month. That difference of $850 a month might be the margin that lets you hold the property through a tenant transition or a rate rise without needing to sell. It also means you're not locking cash into equity you can't access. When you apply for your second investment loan, lenders calculate your borrowing power based on your income, your debts, and the equity you hold. If you've been paying down principal for three years, that equity is still there, but your monthly commitments are higher, which reduces how much the lender will let you borrow next time.

Rental income is assessed at 80 per cent of the lease amount when lenders calculate your borrowing power

Lenders don't count the full rent as income when they're working out what you can afford to borrow. They apply a shading factor, usually 80 per cent, to account for vacancy, maintenance, and management costs. If your property rents for $650 per week, the lender will use $520 per week in their serviceability assessment. That shading sits alongside the 3 percentage point buffer that APRA requires lenders to add to your loan rate when they test whether you can afford the repayments.

For a buyer purchasing a house in Nambour at the current median of around $862,000 with an 80 per cent loan, rental income of $680 per week would be shaded to $544 per week for serviceability purposes. The loan amount of roughly $690,000 would be assessed at a rate 3 percentage points above the actual product rate, meaning the lender tests whether you can afford repayments as if the rate were significantly higher than what you'll actually pay. If you're earning $120,000 a year with no other debts, that serviceability buffer still leaves room to borrow, but it tightens quickly if you're carrying a large home loan or personal commitments on top of the investment.

Rental income also matters for your deposit. If you're buying your first investment property and you're living in your own home with a mortgage, you'll need to show you can service both loans. If you're refinancing your home to pull equity out for the investment deposit, the refinance has to be completed and settled before you exchange contracts on the investment property, otherwise the equity won't be available in time. We regularly see buyers assume they can exchange first and settle the refinance later, but lenders won't release funds until settlement, and settlement can't happen without the deposit already paid.

Loans against property in Noosa, Coolum, and Mooloolaba are assessed the same way as loans in Caloundra or Nambour, but the equity position is different

A unit in Tewantin at the current median of around $645,000 with rental income of $650 per week will deliver a gross yield above 4 per cent. A house in Sunshine Beach at the current median of $3,000,000 with rent of $1,400 per week will deliver a yield of 2.54 per cent. Both are assessed using the same APRA serviceability buffer, the same 80 per cent rental shading, and the same deposit requirements if you're borrowing above 80 per cent of the purchase price. The difference is in the cash flow and the capital growth assumption. The Tewantin unit might cost you $200 per month out of pocket after rent and deductions. The Sunshine Beach house might cost you $4,000 per month. You're holding the Sunshine Beach property for capital growth, not income, and that only works if you can afford to cover the gap every month without selling.

Buyers often ask whether they should target high-yield suburbs like Sippy Downs or Nambour, or save for longer and buy in a capital-growth suburb like Coolum Beach or Peregian Springs. The answer depends on whether you're trying to build cash flow now so you can borrow again sooner, or whether you're holding for ten years and can afford to carry a higher shortfall. A unit in Sippy Downs at a 5 per cent yield might be neutral or positively geared within a few years if rents keep rising and you've locked in a portion of your loan at a fixed rate. A house in Coolum Beach at a 3.2 per cent yield will likely stay negatively geared for most of the time you own it, but it might double in value over a decade if the Sunshine Coast's structural undersupply continues. Neither is wrong, but they're funding two different strategies, and the loan structure that works for one won't suit the other.

You can use equity from your current home or investment property as a deposit without selling or refinancing the whole loan

If you own a property worth $900,000 with a loan of $500,000, you've got $400,000 in equity. Lenders will typically let you borrow up to 80 per cent of the property's value without needing to pay Lenders Mortgage Insurance, which means you can access up to $720,000 in total debt against that property. You're already using $500,000, so you've got $220,000 available to pull out. That $220,000 can be used as a deposit and for settlement costs on your next purchase, and it stays quarantined as a separate loan split so the interest on that portion remains deductible against your investment income.

We've worked with buyers who refinanced their Buderim family home to release $180,000 in equity, then used that as a 20 per cent deposit on a $900,000 house in Caloundra West. The home loan stayed in place with a new split added for the equity release. The investment loan was written as a separate facility secured against the Caloundra West property. Both loans were interest-only for the first five years, keeping repayments low while the buyer built a rental history and waited for the Caloundra West property to increase in value. Eighteen months later, they refinanced the investment property to access equity again and purchased a unit in Maroochydore. The total portfolio sat at just under $2 million in property value with around $1.5 million in debt, all structured so that every dollar of interest was deductible and every loan could be managed independently.

That approach only works if your income can service the total debt, if you've kept your loan splits clean from the start, and if you're not using any of the investment loan funds for private purposes. Lenders and the ATO both track how borrowed money is used. If you pull $200,000 out of your home and use $150,000 for the investment deposit and $50,000 to renovate your kitchen, the interest on that $50,000 is not deductible. The same rule applies to offset accounts. If you're using an offset against your investment loan and you deposit money into it that's not related to the investment property, you're diluting the deductibility of the interest. Most buyers don't structure their loans with this level of detail until they're buying their third or fourth property, and by then it's too late to go back and fix the first one without refinancing everything.

Fixed and variable splits let you lock in part of your rate while keeping access to offset and redraw on the rest

A fixed rate gives you certainty over your repayments for the fixed period, which can be one to five years depending on the lender and the product. The downside is that you can't make extra repayments above a small annual threshold, you can't redraw, and you can't link an offset account to the fixed portion. If you fix your entire investment loan and then need to access cash or pay the loan down early, you'll face break costs, which can run into the tens of thousands of dollars if rates have moved in the lender's favour since you fixed.

Splitting the loan lets you fix part of the debt and keep the rest variable. A common structure is 50 per cent fixed and 50 per cent variable, but it can be any ratio that suits your risk tolerance and cash flow. The variable portion keeps your offset and redraw available, and it gives you flexibility to pay down the loan or refinance that split without triggering break costs. The fixed portion keeps half your repayments stable, which makes budgeting simpler and protects you if variable rates keep rising. You're not guessing which way rates will move, you're just managing the risk on both sides.

For an investment loan of $700,000, you might fix $350,000 at a rate that's currently sitting somewhere in the low sixes for a three-year term, and leave $350,000 variable at a rate in the mid-to-high sixes. If variable rates drop, you benefit on half the loan. If they rise, you're protected on the other half. The fixed portion also makes it easier to forecast your after-tax position, because you know exactly what your interest bill will be for the next three years on that portion of the debt. That certainty matters more when you're holding multiple properties and trying to project your cash flow across the whole portfolio.

Investment loans written after May 2026 for established property are affected by changes to negative gearing rules from the 2027-28 tax year

Under legislation that received royal assent in June, rental property losses on established dwellings purchased after 7:30pm AEST on 12 May 2026 will be deductible only against income from residential property from the 2027-28 income year onward. That means if you buy an established house or unit after that date, any shortfall between your rental income and your loan interest and other costs can't be offset against your salary. It can only be offset against other rental income or against capital gains when you sell a residential property. Losses can be carried forward indefinitely, but they can't reduce your pay-as-you-go tax until you have other residential property income to offset them against.

New builds are exempt. If the property you're buying was constructed on previously vacant land, or if it's part of a development that increased the total number of dwellings on the site, you can still negatively gear it against your salary under the old rules. The exemption is permanent for that property, even if you sell it years later and the next buyer purchases it as an established dwelling. Properties purchased before the May cut-off, including those under contract on that date, are grandfathered and can continue to be negatively geared in the traditional way for as long as you hold them.

If you're buying in a suburb like Baringa, which is part of the Aura master-planned community and still delivering new stock, or in Palmview, where construction is ongoing, you're buying a new build and the new rules don't apply to you. If you're buying an established unit in Mooloolaba or an established house in Buderim after May, the new rules do apply. You'll still get the deduction, but only against other residential property income, which means your strategy has to assume you'll either build a portfolio quickly or hold the property long enough that capital growth makes up for the loss of the tax benefit in the early years.

Capital gains tax treatment is also changing from 1 July 2027. For gains that accrue after that date, the 50 per cent discount is being replaced with cost base indexing and a 30 per cent minimum tax rate on real gains. For properties you already own, gains up to 1 July 2027 will be taxed under the current rules, and gains after that date will be taxed under the new rules. You can choose to get a valuation as at 1 July 2027 to split the gain, or you can use an ATO formula. The detail matters if you're planning to sell within the next five years, but if you're holding for ten or fifteen years, the indexing might actually reduce your tax compared to the current discount, depending on inflation.

Body corporate fees and council rates in unit developments reduce your net rental income but are fully deductible

If you're buying a unit, your annual outgoings will include body corporate fees on top of council rates, insurance, and management costs. In a suburb like Mooloolaba, where the unit market is well established and many buildings are older high-rises along the Esplanade, body corporate fees can sit anywhere from $5,000 to $12,000 per year depending on the facilities and the building's sinking fund requirements. Those fees are deductible, but they still come out of your cash flow every quarter, and they reduce the net return you're getting from the rent.

A unit purchased at Mooloolaba's current median of around $855,000 with rent of $675 per week will generate $35,100 in gross rental income per year. After management fees at 8 per cent, council rates of around $2,500, insurance of $1,200, and body corporate fees of $8,000, your net income before loan interest is roughly $21,600. If you've borrowed $684,000 at 80 per cent LVR and you're paying interest only at current investment rates, your annual interest bill might be $45,000. Your loss for the year is $23,400, and that loss is deductible. If you're earning $140,000 and paying tax at 37 cents in the dollar on the top slice, that deduction saves you around $8,650 in tax. Your actual out-of-pocket cost for the year is closer to $14,750, or roughly $1,230 per month. That's the real cost of holding the property, and it's the figure you need to be comfortable with before you sign the contract.

If body corporate fees rise by $1,000 per year, or if interest rates rise by half a per cent, your monthly shortfall increases, and you need to know that you can cover it without selling. The deduction softens the impact, but it doesn't eliminate it, and the deduction only works if you've got enough taxable income to offset the loss against. If you're buying multiple properties and your total losses exceed your salary, the deduction is quarantined and carried forward under the new rules, or it simply doesn't provide a tax benefit in that year under the old rules because you've got no tax to reduce.

Call one of our team or book an appointment at a time that works for you. We'll structure your loan so that every split, every offset, and every dollar of interest is working toward the next property, not just the one you're buying now.
