How Much Super Do I Need to Buy Investment Property Through My SMSF?
Most lenders require $200,000–$250,000 in SMSF assets, but the real number depends on the deposit, liquidity buffer, and serviceability. YML Group explains exactly what you need.
One of the most common questions our SMSF mortgage brokers receive is: “How much super do I actually need before I can buy an investment property through my SMSF?” The short answer is that most lenders require a minimum of $200,000–$250,000 in total SMSF assets — but the real answer is more nuanced, and depends heavily on the property you want to buy, where it is, and how much liquidity your fund will retain after the purchase.
The Minimum Fund Balance Rule
SMSF lenders apply a minimum fund balance requirement because they need confidence that the fund can service the loan even during periods of vacancy or unexpected costs. Most residential SMSF lenders require a minimum of $200,000–$250,000 in total fund assets at the time of application. Some lenders — particularly for higher-value properties in Sydney or for commercial SMSF loans — require $300,000 or more.
However, meeting the minimum fund balance threshold is just the beginning. There are three other critical numbers you need to hit simultaneously.
The Three Numbers You Need to Hit
1. The Deposit (30–35% of Purchase Price)
Unlike a standard home loan where you can purchase with as little as 5–10% deposit, SMSF lenders require a minimum deposit of 30–35% of the purchase price — and this deposit must come entirely from SMSF funds. For a $600,000 Byron Bay investment property, that means $180,000–$210,000 from your SMSF. For a $1,000,000 Sydney property, you need $300,000–$350,000 from the fund.
2. The Liquidity Buffer (3–6 Months of Costs)
After drawing down the deposit, your SMSF must retain enough cash to cover at least 3–6 months of loan repayments, property management fees, council rates, insurance, and strata levies. Lenders assess this as part of serviceability. Depleting your fund to zero for the deposit is not acceptable — most advisors recommend retaining at least $30,000–$50,000 in liquid SMSF assets after purchase.
3. Serviceability (The Loan Must Cash Flow)
The SMSF must demonstrate it can service the ongoing loan repayments from a combination of fund contributions, rental income, and existing investment returns. Lenders stress-test the loan at rates 2–3% above the current rate to ensure the fund can still service the debt if interest rates rise.
A Practical Example — Sydney vs Byron Bay
Sydney, $900,000 apartment: You’d need approximately $315,000 for the deposit (35%) plus $40,000 liquidity buffer = minimum ~$355,000 in SMSF assets before purchase. Plus sufficient ongoing contributions and rental income to service a $585,000 loan.
Byron Bay, $700,000 house: You’d need approximately $245,000 for the deposit (35%) plus $35,000 buffer = minimum ~$280,000 in SMSF assets. Rental income from a well-managed Byron Bay short-term rental can be strong enough to service the loan with modest ongoing contributions.
How to Build Your SMSF Balance Faster
- Maximise concessional contributions: The 2026 Budget increased the annual cap — salary sacrifice into your SMSF up to this limit to grow your balance with pre-tax dollars
- Non-concessional contributions: After-tax lump sum contributions (subject to annual caps) can rapidly top up your fund ahead of a planned property purchase
- Bring-forward rule: If you’re under 75, you can bring forward up to 3 years of non-concessional contributions in a single year — potentially a significant lump sum
- Spouse contributions: If your partner has lower super, contribution splitting can help pool balances more quickly
