Key Takeaways
- For a geared purchase, the amount follows a formula of deposit plus purchase costs plus a post-settlement cash buffer, all held in the fund before settlement.
- From 10 August 2026, a new SMSF loan can only buy commercial (business real) property. Residential property can still be bought, but only with the fund’s own cash or a loan taken out earlier.
- A $700,000 commercial purchase typically needs about $283,000 in the fund up front. Buying $700,000 of residential outright means finding close to the full price plus costs.
- Fund balance is not the only test. Contribution history, member age and rental income all shape what a lender will approve.
Most business owners researching how much super to buy property in an SMSF hear the same vague figure, ‘about $200,000’. It is repeated so often that many rule themselves out too early, or assume they are ready when they are not. The real number depends on the property, whether the fund can borrow, the purchase costs in your state and the cash the fund must hold after settlement, and it can be worked out rather than guessed.
A Self-Managed Super Fund (SMSF) purchase is less forgiving than a personal one. Contribution caps limit how fast money moves into the fund, so you cannot top up savings at the last minute. It helps to understand how an SMSF loan broker reads the fund’s position before you commit to a contract, and what a lender expects to see on settlement day.
The 2026 borrowing rules changed the answer. A fund can still borrow to buy commercial premises but not a residential investment, and that single distinction moves the number more than any other factor.
What the 2026 Rules Changed for SMSF Borrowing
Since 10 August 2026, a new SMSF loan can only be used to buy business real property, so residential investments can no longer be bought with borrowed money inside super. SMSF property loans are written as a limited recourse borrowing arrangement (LRBA), where the lender’s claim is limited to the property being bought and cannot reach the fund’s other assets. The Treasury Laws Amendment (Tax Reform No. 1) Act 2026 changed what an LRBA can buy.
Under the changes to SMSF borrowing, any LRBA entered into on or after 10 August 2026 can only acquire business real property, broadly land and buildings used wholly and exclusively in a business. Existing arrangements are unaffected. Residential LRBAs entered into before that date continue, and can generally be refinanced on similar terms, and contracts exchanged before 10 August 2026 are protected even if they settle later. A fund can still buy residential property outright with its own cash, provided it meets the fund’s other rules. What it can no longer do is borrow to buy one.
Formula for a Geared SMSF Purchase
When a fund borrows to buy commercial premises, the amount it needs before settlement comes down to three parts:
Deposit
A commercial SMSF loan usually needs a larger deposit than a standard home loan. Because the lender’s recourse is limited to the property, it lends less against it, so funds commonly need around 20% to 30% of the price, sometimes more depending on the property, location and lease.
Purchase Costs
On top of the deposit, the fund pays the transaction costs. Stamp duty is the largest. On a $700,000 purchase in New South Wales, transfer duty is around $26,000 under the Revenue NSW scale, and it varies by state and property type. Add legal and conveyancing fees, lender fees and valuations, and the cost of setting up the bare trust (also called a holding or custodian trust) that an LRBA requires to hold the property until the loan is repaid, usually a few thousand dollars with a corporate trustee. Around 5% to 6% of the price is a reasonable planning figure for total costs, and commercial purchases can involve Goods and Services Tax (GST) that your accountant should review before exchange.
Liquidity Buffer
This is the part the ‘$200,000 rule of thumb’ ignores, and it often decides approval. Lenders, and later the fund’s auditor, want cash or liquid assets left in the fund after settlement, because it must keep covering loan repayments during vacancies, insurance, rates, accounting and audit fees, and any pension payments. Many lenders look for around 10% of the property value, or a reserve clearly able to cover the fund’s commitments. A fund that empties itself to settle is one vacancy away from trouble.
What $700,000 Looks Like in Practice
The same $700,000 price produces very different numbers once the borrowing rules are applied:
Commercial Premises
Assume a lender wants a 25% deposit, within the usual commercial range. The deposit is $175,000, purchase costs run to about $38,000, and a buffer of around 10% adds $70,000, so the fund needs roughly $283,000 before settlement. Rent does more work here than on a home. Commercial premises often yield more, illustratively around 6% versus 3.5%, so on $700,000 that is about $42,000 of annual rent to service the loan. Business owners can also lease their own premises from the fund at market rent under a compliant lease.
Residential Property
An SMSF can no longer borrow to buy residential property, so the number changes shape. Without a loan, the fund needs close to the full price plus costs, roughly $730,000 on a $700,000 purchase once transfer duty and legal fees are counted, and it still needs a reserve for rates, insurance and maintenance. For many buyers, the practical alternative is buying in personal names outside super, where an investment loan broker can arrange finance and contribution caps do not limit how much you put in.
How Lenders Assess a Commercial SMSF Loan
Fund balance gets you to the table, but lenders weigh several things beyond it when judging whether the loan stays serviceable.
Contribution history is evidence. A fund with years of steady employer and voluntary contributions shows income that will keep flowing, while a fund recently set up with a single rollover tells a thinner story at the same balance.
Member age matters for the same reason, since contributions usually slow or stop at retirement, so lenders look at how many contributing years remain across the loan term. They also apply interest-rate buffers and treat rent conservatively. Because policy differs by lender, working with a broker who has access to a broad lender panel earns its keep, as a fund one lender declines can fit another’s rules.
Building the Fund to Purchase-Ready
Contributions are the main way to close a shortfall, but they are capped, so getting a fund purchase-ready usually takes planned contributions over several years rather than a lump sum before auction. Concessional (before-tax) and non-concessional (after-tax) contributions both have annual limits, and exceeding them brings tax consequences.
There may be room to bring forward future non-concessional caps, but whether that suits you is a financial-advice question, so plan the timeline with your adviser and accountant well before any contract date.
Checking Whether Your Fund Is Ready
Before you shortlist a property, four checks show whether the fund is genuinely ready:
- Confirm the fund holds the full amount, deposit, costs and buffer, for your price bracket.
- Check that rent plus ongoing contributions service the loan under a buffered rate.
- Confirm a contribution history a lender can rely on, with enough working years ahead.
- Check the fund stays diversified enough that one asset does not carry the whole retirement.
Where any answer is no, forcing it has real costs. A stretched fund cannot absorb a vacancy, a rate rise or a repair bill, and you cannot inject cash beyond the caps when things tighten. Waiting a year or two while contributions build is often what a clean approval looks like in hindsight.
Your Fund’s Real Property Number
The amount your fund needs is knowable, not a guess. Run the formula against your target price, allow for whether you can borrow, and you will know if you are ready now, a year away, or better off investing outside super for now. Because deposit levels, buffers and serviceability differ by lender, checking your fund against a broad panel turns a rough estimate into a plan you can act on.

Frequently Asked Questions (FAQs)
1. How much super do I need to buy a property in an SMSF?
For a geared commercial purchase, enough to cover the deposit (commonly around 20% to 30%), purchase costs of roughly 5% to 6%, and a cash buffer often near 10% of the value, which lands around $250,000 to $285,000 on a $700,000 purchase. For residential property, which can no longer be geared, the fund needs close to the full price plus costs.
2. Can an SMSF still borrow to buy residential property?
Not under a new loan. Since 10 August 2026, a new SMSF borrowing arrangement can only buy business real property. An SMSF can still buy residential outright, keep a loan taken out before that date, or refinance one on similar terms.
3. Is $200,000 enough super to buy property?
Sometimes, for a lower-priced geared commercial purchase. At $200,000, the formula typically supports a purchase of roughly $450,000 to $550,000 once deposit, costs and buffer are counted. A $700,000 purchase usually needs more.
4. Why do SMSF loans need bigger deposits than normal home loans?
Because the loan is limited recourse, the lender can only claim the property itself, not the fund’s other assets. That extra risk is priced through lower lending ratios, so deposits of around 20% to 30% are common, not the 5% to 20% seen on standard loans.
5. What is the liquidity buffer and why does it matter?
It is the cash or liquid assets a fund keeps after settlement, often around 10% of the value. Lenders and auditors expect it because the fund must keep meeting repayments, insurance, rates and administration costs through vacancies. A fund that empties itself at settlement is a real approval risk.
6. Can I top up my SMSF quickly to reach the deposit?
Usually not. Contributions are capped each year, so building a fund to purchase-ready generally takes planned contributions over several years. Bring-forward rules may help some people, but eligibility is a financial-advice matter, so check with a licensed adviser first.
