Investment property vs shares in Australia: an honest comparison

Property's reputation as the higher-returning asset class in Australia is mostly a leverage story, not a fundamentals story. A diversified ASX or global ETF has out-earned the average residential property on an unleveraged total-return basis in most rolling decades since the 1990s. The reason property still mints millionaires is that banks will lend you 90% of the purchase price at investor rates, and almost no retail investor borrows that aggressively to buy shares. Once you strip out the gearing, the contest looks very different.

The framework both assets share

Total return on either asset breaks into the same four components: capital growth, income yield, costs, and tax. The levers just look different. Australian residential property has historically delivered around 5-7% nominal capital growth over long horizons, depending on the city and the era, with gross rental yields of 3-5% and net yields closer to 2-3% once outgoings land. Diversified equities have delivered 8-10% nominal total return over comparable horizons, with around 4% of that coming as dividends in the ASX-heavy case and 2% in the global case.

Costs are where the asymmetry starts. A property round-trip burns 5-7% of the purchase price in stamp duty, conveyancing, buyer's agent if used, sale agent commission, and exit legal. An ETF round-trip on a CHESS-sponsored broker costs roughly 0.1% each way. On a $750,000 property, that's $40,000-$50,000 of friction the ETF investor never sees. Spread that across a ten-year hold and it's still meaningful drag.

Leverage is the hidden core

A 90% LVR property purchase gives you ten times exposure for one times equity. A diversified ETF on margin caps out around 50% LVR at most retail brokers, and margin calls are real and fast. The equity-on-equity return on a leveraged property looks higher precisely because of the gearing, not because property is fundamentally a higher-return asset. If property grows 5% and you put down 10%, your equity return on the first year is roughly 50% gross of costs. That same 5% growth on an unleveraged share portfolio is just 5%.

The same maths cuts the other way in a downturn. A 10% fall on a 90% LVR property wipes the whole deposit. The same fall on an unleveraged ETF is annoying and recoverable. Property investors rarely model this, partly because they can't see the daily price and partly because the cash drain of servicing the loan dominates their attention.

Risk and liquidity

Shares are liquid, diversified, politically independent, and priced every second the market is open. Property is illiquid, concentrated in a single asset, tenant-dependent, and priced only when you sell. A three-month sale process is fast. Six months in a soft market is normal. That illiquidity is also a behavioural feature: the person who can't sell on a bad Tuesday is the person who actually holds for the long horizon the maths assumes.

Sequence-of-return risk hurts property more for the same reason. An ETF investor who needs cash next month sells on the open. A property investor who needs cash next month discounts 5-10% for a quick sale and pays full agent commission anyway. If the rest of your balance sheet is thin, that liquidity premium matters more than headline return numbers suggest.

Tax: the levers favour different investors

Both assets get the 50% CGT discount on gains held longer than twelve months by an individual. After that, the treatments diverge. Property gets depreciation on the building (Division 43) and on plant-and-equipment for new or substantially renovated dwellings, plus deductibility of loan interest and outgoings against other income via the much-debated negative-gearing mechanism.

Shares get franking credits on Australian dividends, which for a low-or-middle-bracket investor adds roughly 0.5-1% after-tax return on the franked portion of the portfolio. Self-funded retirees on low marginal rates can refund the franking credit in cash, which is one of the more generous settings in the OECD. Companies and trusts holding shares face their own treatment that doesn't map cleanly onto either of the individual cases.

The two articles worth reading alongside this one are negative gearing in 2026 on the property side and the CGT investment property worked example for the exit-tax mechanics that apply to both asset classes at different rates.

A 10-year worked example

Take $200,000 of starting capital and a ten-year horizon, with the investor sitting on a 37% marginal rate.

Path A: leveraged property. $150,000 of the capital is the deposit on a $750,000 unit at 80% LVR; the other $50,000 covers stamp duty, conveyancing, and lender fees. Mortgage of $600,000 at 6.2% costs $37,200 in year-one interest. Gross rent at 4% yields $30,000; outgoings of $11,000 leave net rent of $19,000. Pre-tax cash drain is about $18,200 in year one, partly offset by depreciation and the negative-gearing tax refund of roughly $6,700, for a real out-of-pocket cost near $11,500.

At 5% capital growth, the property is worth roughly $1,222,000 in year ten. Mortgage paydown over ten years on a principal-and-interest schedule is around $90,000, leaving $510,000 owing. Gross equity is $712,000. Sale costs of $45,000 (agent, marketing, legal) bring net proceeds to $1,177,000. Cost base, including buy-side stamp duty and legal, is $785,000. The capital gain is $392,000, halved by the CGT discount to $196,000 of taxable gain, taxed at 37% for $72,500 of CGT. Net cash to the investor after the loan is repaid: roughly $595,000. Subtract ten years of after-tax cash drain at $11,500 a year (~$115,000) and the investor ends with around $480,000 in their pocket from the original $200,000.

Path B: unleveraged ETF. The $200,000 goes into a diversified global ETF returning 8% nominal, reinvesting dividends. After ten years the parcel is worth roughly $432,000. The capital gain is $232,000, halved to $116,000 of taxable gain, taxed at 37% for about $42,900 of CGT. Net cash: about $389,000. No cash drain along the way; the dividends compound quietly inside the return.

Path A wins by roughly $91,000 after tax in this scenario, and the entire margin comes from leverage. Re-run Path A without the loan, putting $200,000 cash into a $200,000 unit in a regional centre at the same growth and yield assumptions, and the property finishes well behind the ETF once stamp duty, sale costs, and the lower compounding base do their work. The leveraged version also assumed nothing broke: no extended vacancy, no special levy, no rate-driven cash crunch forcing a sale in year four. Tilt any of those and the gap narrows fast.

Which one actually wins for you

The honest answer depends on three things: marginal tax rate, time horizon, and behaviour. Numerate high-income earners with long horizons and stable cash flow typically end up owning both, because the diversification matters more than picking a winner. Investors who can't tolerate tenant calls, special levies, or vacancy stress should stick with shares; the after-tax return is fine and the sleep is better. Investors who would otherwise spend the cash often do better with property because the mortgage forces the saving, and a forced 4% return beats a theoretical 8% the investor never actually accumulates.

Two practical steps before committing capital either way. Run a realistic net-yield calculation using the rental yield calculator with conservative outgoings; the gap between gross and net is unpacked in understanding rental yield. Then sketch a plausible exit using the CGT calculator so the after-tax sale figure is a real number and not a spreadsheet daydream. Burbfinderprefills both with the suburb and median data for the property you're actually considering, which is closer to a defensible base case than the listing-agent yield you started with.

The cleanest mental model is this. Property is a leveraged bet on a single illiquid asset that the tax system rewards for being held. Shares are an unleveraged bet on a thousand liquid assets that the tax system rewards more modestly. Whether the leverage is worth the concentration is a personal call about cash flow, temperament, and the next decade of interest rates, not a universal truth.
