Using Leverage to Buy an Investment Property in Australia

Important: General information only. It isn’t personal advice. Consider speaking with a licensed adviser and tax agent about your situation.

Why leverage is the main event

Let’s call it straight. The biggest benefit of buying an investment property isn’t the tax perks. It’s leverage. You’re using the bank’s money to control a larger asset than your savings alone could buy. If the property grows, small percentage increases on a big asset can create outsized gains on your equity. If it doesn’t grow, leverage can hurt. Interest keeps ticking, costs add up, and losses compound. Tax rules can soften the blow, but they don’t turn a poor asset into a good one.

This guide shows how leverage magnifies outcomes, where tax fits, how to stress test your numbers, and the practical loan and structure choices that matter. When it helps, we’ll point you to the ATO page for the rule in black and white and link to deeper strategy posts like Should I invest or pay off my mortgage, What is debt recycling and Tax-efficient investing in Australia.

Leverage 101: how borrowing amplifies results

Say you buy a $1,000,000 investment property with a $100,000 deposit and a $900,000 loan. If the property grows 6% in year one, it’s now worth $1,060,000. That’s a $60,000 gain on $100,000 equity before costs. On paper that’s a 60% return on equity. If growth is 0%, your equity didn’t move but costs still happened. If value falls 2%, you’re down $20,000 on the asset value plus your holding costs. Same leverage, very different outcomes.

Here’s a simple visual showing how equity could move over time when price growth is strong, flat or negative, assuming an interest-only loan so we isolate the leverage effect.

What to watch:

• LVR (Loan-to-Value Ratio): higher LVR means more leverage, more upside, more downside. Above 80% LVR you’ll usually pay LMI (Lenders Mortgage Insurance), which is a borrowing cost you can generally claim over time for investment property.
• Serviceability buffers: lenders assess your capacity at a buffer above your actual rate to see if you can handle rate rises. This reduces how much you can borrow and protects you from cash-flow strain.
• Yield versus growth: a healthy rent helps cash flow, but growth tends to drive your long-term result when you’re geared.

The tax settings investors care about

Tax is the booster, not the engine. It helps a good property look a bit better and makes losses a bit less painful, but it won’t rescue poor selection.

Interest deductibility
Interest on money borrowed to buy an income-producing property is generally deductible. If you redraw or split loans for private use, you’ll usually need to apportion interest. The ATO sets out the principle here: rental property interest expenses.

Borrowing expenses (including LMI)
Upfront costs like loan application fees and LMI are typically deductible over the lesser of 5 years or the term of the loan. See the ATO’s borrowing expenses.

Depreciation

• Capital works (Division 43): structural works like the building shell and fixed items are deductible over long periods. ATO: capital works deductions.
• Plant and equipment: second-hand residential assets purchased after 9 May 2017 have tighter rules. The ATO explains what you can and can’t claim under depreciating assets in a rental property.

Negative gearing
If your rental income is less than your deductible expenses, the loss can often be used to reduce taxable income from other sources. This can help high-income earners manage cash flow in the early years, but it only makes sense if you’re confident about the property’s growth and your ability to carry the holding costs. The ATO’s overview of rental expenses and records covers what’s claimable.

Capital gains tax and the 50% discount
Sell after holding more than 12 months and individuals may be eligible for the 50% CGT discount. That can be significant over a long hold, but it isn’t guaranteed. If the property underperforms, the discount doesn’t magic up a gain. See CGT discount.

Buying an investment first versus buying your own home

This is where timing can change your trajectory. Buying your own home too early can make you asset rich, cash poor, and it can slow your wealth building. The reason is simple. Your home loan interest isn’t deductible. Every repayment is made with after-tax dollars. On a 47% marginal tax rate, every $1 of interest you pay at home costs about $1.89 in pre-tax income. If your annual interest bill is $40,000, you need roughly $75,472 in pre-tax earnings just to cover the interest, before principal, rates, insurance and maintenance.

With an investment property, the interest is generally deductible, and the property’s expenses can offset rental income. You’re still paying interest, but the tax system allows a portion of those costs to reduce your taxable income. In plain English, you’re much closer to paying the interest with pre-tax dollars. That does not make the property a good asset by itself. It just means the cash flow is more tax efficient while you wait for growth.

So should you rent, invest first, then buy your home later? Sometimes, yes. If getting into your perfect suburb means overextending, rent where you want to live and buy an investment in a location that makes financial sense. That’s rentvesting. It often pairs well with a plan to buy your home later when your income and deposit are stronger and your investment has grown.

There’s another layer. If you already own a home with a big non-deductible mortgage, consider reading What is debt recycling. Done correctly, it can help convert non-deductible home debt into deductible investment debt over time. If you’re still deciding whether to direct spare cash to the loan or to investing, this breakdown helps frame the math Should I invest or pay off my mortgage.

Bottom line on timing: buying a home can be the right move for lifestyle, family stability and sleep-at-night value. Just be honest about the trade-offs. Buying too early can slow wealth if it leaves you stretched, with no buffers, and stuck in an asset that grows slowly. Buying an investment first can allow your money to work harder if you pick a quality property and manage risk. The right answer is personal. The wrong answer is buying a home as a reflex before running the numbers.

Choosing the property: growth first, yield second

Cash flow matters. Growth usually matters more when you’re leveraged. You want an asset with a high chance of rising in value over time, not just covering the bills.

What tends to support growth:

• Strong owner-occupier demand in the area
• High land value component relative to improvements
• Scarcity and tight supply pipelines
• Livability factors: schools, transport, lifestyle
• Government or private infrastructure that improves amenity and access

When yield carries more weight:

• You’re close to your serviceability ceiling
• You want a cash-flow buffer while rates are elevated
• You’re building a portfolio and want diversity in income streams

Finance strategy: structure matters more than a tiny rate win

The wrong loan structure can cost more than a slightly higher rate.

Interest-only versus principal and interest

• Interest-only can improve cash flow and keep options open. Some investors use IO for the first few years to build buffers or fund improvements, then switch to P&I later.
• P&I reduces the loan over time, which lowers interest and risk but ties up more cash each month.

Offset account versus redraw
An offset linked to your investment loan gives flexibility. It’s simpler for record-keeping when separating private cash from deductible debt. Redraw can blend purposes over time if you’re not careful, which can complicate interest deductibility.

Equity release versus cross-collateralising
Many investors prefer setting up a separate split or standalone facility for the deposit and costs rather than cross-collateralising properties. Cleaner structure, cleaner accounting.

What lenders look at

• Income shading and DTI ratios
• HEM living expense benchmarks
• Assessed rent and vacancy assumptions
• Serviceability buffers above your actual interest rate

The cash-flow reality: stress test before you buy

Too many investors only run the best case. Stress test instead. Model a year of holding costs and then layer rate rises, vacancies and unexpected repairs.

Here’s a quick visual. We’ve assumed a $1,000,000 property, $900,000 interest-only loan, gross rent at 3.5% and other holding costs at 1.5% of property value. It shows how fast interest can overwhelm rent if rates lift.

Build your own stress test:

• Interest at the current rate, then add +1% and +2% scenarios
• Other costs: council rates, insurance, property management, strata, land tax, maintenance
• Rent assumptions: net of vacancy and letting fees
• Repairs: include a buffer for the stuff that breaks at the worst time

Case studies: where leverage helps, where it hurts

Case A: Growth does the heavy lifting

• Purchase: $1,000,000 with $100,000 deposit and $900,000 loan
• Assumptions: 6% p.a. price growth, rent 3.5%, other costs 1.5%, interest-only at 6.5% for 5 years
• After year 5: value ≈ $1,338,226, equity ≈ $438,226 before costs. Even if cash flow has been tight, value growth swamps small line items. Negative gearing may have reduced tax along the way, but the hero is price growth.

Case B: Flat market for 5 years

• Same setup, 0% price growth
• After year 5: value ≈ $1,000,000, equity unchanged at the asset level, but you’ve paid years of interest and costs. Negative gearing may have softened the blow if you’re a high-income earner, but it’s still a negative return on equity once you add stamp duty and selling costs. This is where buying quality and patience matter.

Case C: Down market for 3–4 years

• Say the property falls 2% p.a. for 4 years
• After year 4: value ≈ $923,000. Against a $900,000 loan you’ve got little equity and less room to move. Refinance can get harder, buffers get tested, and the strategy can be forced to unwind at the wrong time. Tax deductions don’t fix that.

Takeaway: leverage multiplies whatever you buy. Choose well, run conservative numbers, and keep cash buffers.

Deductions in context: what you can usually claim

• Interest on the investment loan: typically deductible when the borrowing is used for the rental property. ATO rules here: interest expenses.
• Borrowing costs and LMI: generally deducted over up to 5 years or the loan term, per borrowing expenses.
• Repairs and maintenance versus improvements: repairs fix wear and tear and are usually deductible now; improvements are capital and handled differently.
• Capital works and depreciation: see capital works and depreciating assets.
• Travel to residential rentals: generally not deductible since 1 July 2017 for individuals.
• CGT: if you hold more than 12 months you may get the 50% discount. See CGT discount.

Ownership and structure: keep the end game in mind

Personal name is the simplest and cheapest. You may access the 50% CGT discount and negative gearing can offset salary. Trusts can add flexibility for income streaming and estate planning but come with extra cost and complexity. Companies can be useful in some cases but don’t get the 50% CGT discount. Structures are a legal and tax decision, so it’s worth getting advice before you buy.

Rentvesting and alternative paths

If buying your own home is a stretch but you want exposure to growth areas, rentvesting could be worth a look. You rent where you want to live and buy an investment in a location that makes better financial sense. It isn’t for everyone, but it can be a way to get on the ladder faster while your lifestyle stays flexible.

FAQ

Is negative gearing still worth it if rates are high
It can be, if your property’s growth outlook is strong and you can handle the cash flow. If growth doesn’t show up, it’s just a loss with a smaller tax bill. The decision should start with asset quality and a realistic stress test.

How much deposit do I need
Plenty of investors target 20% to avoid LMI. Others use less deposit and accept LMI for speed and scale. It comes back to borrowing capacity, buffers and risk tolerance.

Can I claim interest if part of the loan was used for private spending
Usually you’ll need to apportion interest between deductible and private purposes. Clean splits and an offset account can make record-keeping simpler. ATO’s interest expenses page explains the principle.

Is LMI deductible
It’s a borrowing cost, generally deductible over up to 5 years or the loan term. See borrowing expenses.

Can I claim depreciation on an older property
Yes for capital works if eligible. For plant and equipment, second-hand asset rules are tighter after 2017. Check capital works and depreciating assets.

Do I get the 50% CGT discount
Individuals may be eligible after a 12-month hold. ATO: CGT discount. Trusts can flow the discount in many cases. Companies don’t get it.

What if the rent doesn’t cover interest and costs
That’s a cash flow deficit you’ll need to fund. If the property grows strongly, total return can still be fine. If it doesn’t, it’s painful. This is why buffers and a conservative stress test matter.

Should I invest through property or shares
Depends on your goals, risk tolerance and timeframe. Property gives leverage and tangibility. Shares give liquidity and diversification. For a numbers-first lens, see Long-Term Investment Returns in Australia and Tax-efficient investing in Australia.

Where do RSUs fit if I work in tech
Equity income can be lumpy, and it often pairs with investment property decisions around timing, deposits and buffers. If you’re juggling employer shares with property plans, start here: Restricted Stock Units in Australia and the broader guide RSU tax Australia.

Wrap

Leverage is the driver. Tax is the booster. If you buy a quality property in a market with strong long-term drivers and you keep conservative buffers, gearing can accelerate your wealth. If the asset underperforms, the same leverage magnifies the pain. Run the numbers honestly, pressure test your cash flow, and line up the right structure before you jump.
