Can I safely use both margin loans and property loans at the same time?

You can, but the combined risk needs careful modelling. High property gearing already commits you to large repayments, so adding a margin loan can increase vulnerability to both rate rises and market falls. Many investors prioritise stabilising or de‑gearing property first, then use low or no gearing in shares, rather than maximising leverage across both at once.

Key Takeaway

This article explains how gearing in shares compares with gearing in property for Australian investors, focusing on risk, cashflow and tax after the 2026–27 reforms. It contrasts margin loans, which can trigger rapid margin calls if values fall 20–30%, with property loans that are larger, less liquid and stress-tested with a 3% buffer by lenders. It concludes that investors should model both strategies using conservative assumptions and choose the structure that they can safely carry through a downturn.

Borrowing to invest in Australia can work in both shares and property, but the risk profile is very different. Gearing into shares usually uses a margin loan secured by your portfolio; property gearing uses a mortgage secured against real estate. Shares offer liquidity and flexibility but can trigger rapid margin calls. Property gearing is slower-moving, larger and now faces tighter tax and lending rules after the 2026–27 reforms.

If you’re choosing between gearing into shares or property this year, focus on five things: (1) probability of forced selling, (2) cashflow strain, (3) tax treatment, (4) lender rules, and (5) how easily you can de‑gear if conditions turn.

1. What gearing actually means in shares vs property

1.1 Basic definitions

Gearing in shares

You borrow via a margin loan or investment loan.
The loan is secured by listed shares/ETFs or managed funds.
Lenders set a maximum loan-to-value ratio (LVR), often 50–70%.
If prices fall and LVR is breached, you must tip in cash or sell quickly.

Gearing in property

You borrow via a home or investment property loan.
The loan is secured by residential or commercial property.
Banks commonly lend up to 80% LVR without LMI; higher with LMI.
No daily margin calls, but banks model your affordability with at least a 3% rate buffer (APRA guidance).

1.2 Headline pros and cons

Feature / Risk	Gearing in Shares (Margin Loan)	Gearing in Property (Mortgage)
Typical max LVR	~50–70% of portfolio value	~80% without LMI, up to ~90–95% with LMI
Risk of forced sell	High – margin calls if values drop 20–30%	Low day‑to‑day – risk rises only if you can’t meet repayments
Liquidity	High – sell shares in days	Low – sale can take months and incur high costs
Cashflow demands	Interest only, usually variable; can be capitalised short term	Principal & interest or interest‑only; large, regular repayments
Negative gearing rules (post‑2027)	Unchanged for listed shares	Limited for many established properties; new builds largely exempt
Diversification	Easy to spread across sectors and markets	Concentrated in a few properties, often one city
Admin / complexity	Relatively simple, but daily price volatility to manage	More admin: tenants, rates, insurance, maintenance, tax changes

2. Risk: margin call vs mortgage stress

2.1 How losses show up

With margin lending, risk is about speed. A 30% fall in share prices can take your LVR from 50% to near the limit quickly. If you breach, you get a margin call and may have 24–48 hours to add cash or sell.

With property loans, risk is about repayment capacity. Banks already test your repayments with at least a 3% buffer on the actual rate. Stress rises if your income drops, rates jump, or rents stall – not if the property price flicks around on paper.

Roy Morgan’s 2026 research shows over 28% of Australian mortgage holders already sit in ‘at risk’ territory, so layering extra investment debt needs a sober view of mortgage stress.

2.2 Worked example: same equity, different risk

Assume you have $200,000 to invest and are comfortable with 50% gearing on your own capital.

Option A – geared shares

Your capital: $200,000
Margin loan: $200,000
Portfolio value: $400,000
Starting LVR: 50%

If markets fall 30%:

New portfolio value: $280,000
Loan still: $200,000
New LVR: 71%

If the lender’s max LVR is 70%, you’re now in margin call. You’d have to:

Tip in cash (e.g. $4,000–$10,000 depending on policy), or
Sell a chunk at depressed prices, locking in losses.

Option B – geared property

Your capital: $200,000
Purchase: $600,000 established unit
Loan: $400,000 (LVR ~67%)

If the property value falls 30% to $420,000:

Loan: $400,000
LVR: ~95%

You won’t get a ‘margin call’. The risk is cashflow: can you still meet repayments and holding costs? The bank only forces sale if you default, not simply because the value moved.

This is why, in practice, gearing into shares carries faster, mark‑to‑market risk, and gearing into property carries slower, cashflow‑driven risk.

3. Cashflow, tax and the 2026–27 negative gearing changes

3.1 Cashflow differences Shares gearing cashflow - Interest-only is standard. - No rent; you rely on dividends (often 3–5% fully franked) and capital growth. - You choose whether to pay interest from cashflow, dividends, or capitalise temporarily (if the structure permits). Property gearing cashflow - You receive rent but also pay rates, insurance, maintenance, property management and possibly body corporate. - You can choose interest‑only vs principal and interest. That choice heavily affects cashflow and risk – covered in detail in /insights/interest-only-vs-principal-and-interest-investment-gearing-cashflow-tax. Because rent is relatively stable and dividends…

Frequently asked questions

Neither is automatically safer; they carry different types of risk. Margin loans into shares can trigger rapid margin calls if markets fall 20–30%, forcing you to add cash or sell at a loss. Property loans don’t have daily margin calls but create bigger, longer-term repayment obligations, so the main risk is mortgage stress if your income drops or interest rates rise sharply.

The 2026–27 reforms restrict negative gearing on many new established residential properties purchased after the reforms, and alter the capital gains tax discount. New builds keep more generous treatment. Listed shares and ETFs are not directly targeted in the same way, so interest on share investment loans remains generally deductible against investment income under current rules.

Even if a lender allows 60–70% LVR, many cautious investors cap their own gearing at 30–40% to reduce margin‑call risk. Running lower LVR gives you more room for market falls before a margin call and makes it easier to sleep at night. You should also hold cash or an offset buffer earmarked to meet potential margin calls without forced selling.

A geared property generates rent but also incurs rates, insurance, maintenance, management fees and sometimes body corporate costs, along with loan repayments. A geared share portfolio usually only generates dividends, which can fluctuate more quickly than rent. Property cashflow is more complex but often more predictable; shares are simpler administratively but can see dividends cut during downturns.
