A self-managed super fund gives you control, and control is exactly why many SMSF trustees look at private mortgage funds. You get a monthly income stream, secured against real property, from an asset class that does not move with the daily swings of listed markets, and you can see what you are invested in. For a fund that needs reliable income, particularly as members approach or enter pension phase, that is a genuinely useful building block.
But an SMSF is a regulated structure, and you wear two hats: investor and trustee. This article is about the trustee hat, the rules and practical considerations you need to have straight before this kind of investment goes anywhere near your fund.
It is general information, not advice, and the recurring theme is that you should run this past your accountant, auditor, and a licensed adviser before acting.
The sole purpose test comes first
Every SMSF investment has to pass the sole purpose test. It must be made to provide retirement benefits to members, and nothing else.
A private mortgage fund investment clears this easily as long as it is a genuine, arm's-length investment producing income for the fund. Where trustees get into trouble is when a present-day benefit sneaks in, such as the fund lending in a way that helps a member or a relative today, rather than simply earning a return for retirement.
Keep the investment clean and commercial and this is not a problem. The moment a related party benefits, it is.
It has to fit your investment strategy
Your SMSF is required to have a documented investment strategy, and to review it regularly. Before you invest, the strategy needs to actually accommodate this. It should address how the investment fits your diversification, your risk profile, and, critically, your fund's liquidity needs.
That is not a box-ticking exercise. A private mortgage investment is a defined-term, income-focused holding, and your strategy should explain why that suits your fund. If a private mortgage fund would become a large concentration of the fund's assets, your strategy needs to justify that deliberately, because a regulator or auditor will ask.
In-house asset rules: keep it at arm's length
The in-house asset rules limit how much of your fund can be invested in, or lent to, related parties, broadly 5% of fund assets. For a private mortgage fund, the practical requirement is straightforward: the fund and its manager must be genuinely unrelated to you and your members. You are investing in an independent, third-party managed scheme, at arm's length, on commercial terms.
Two things to confirm:
- •The manager is not a related party.
- •The underlying loans are not going to related parties either.
An arm's-length investment in an independent fund sits well outside the in-house asset problem, but it is worth confirming rather than assuming.
Liquidity: model your cash flow before you commit
This is where SMSF trustees most often trip up. Your fund has obligations on fixed timelines:
- •Pension payments, if any members are in pension phase
- •The annual audit and administration costs
- •Tax
A private mortgage investment is committed for the term of the loan and returns capital on a defined date, not on demand. So before you invest, model it. When does capital come back? Does that timing line up with your fund's pension and expense obligations?
If you are in pension phase and drawing minimums, you cannot have all your capital locked in defined-term investments that mature after the payment is due. A contributory structure that lets you ladder across several maturities can help here, staggering when capital returns so the fund has regular liquidity, but the modelling has to be done, not assumed.
Qualifying as a wholesale or sophisticated investor
Most private mortgage funds, including the SL Premium Income Fund, are open only to wholesale or sophisticated investors. An SMSF can qualify, but you need to establish it properly.
The common path is the net assets or gross income test, certified by a qualified accountant. Broadly, the fund holds net assets above the prescribed threshold, or earns gross income above it.
For the SL Premium Income Fund specifically, the minimum investment is $100,000, and investments under $500,000 require a qualified accountant's certificate confirming wholesale or sophisticated status. Your accountant handles the certificate. Your job as trustee is to make sure it is in place before you invest, not after.
It is worth understanding what this threshold means. As a wholesale investor, you give up some of the retail-client protections and disclosure requirements. That is the trade for access. Know that you are making it.
Valuation and reporting for your annual audit
Your SMSF has to be audited every year, and every asset has to be valued at market value and supported by evidence your auditor will accept. Before you invest, check that the manager provides the reporting you will need:
- •Investment statements
- •Income distributions
- •Year-end valuations in a form your auditor is comfortable with
A manager who reports clearly makes your annual compliance simple. One who does not creates work and audit risk every single year. Ask about reporting up front. It is a fair question, and the answer is telling. It is one of several questions worth putting to any manager before you commit, which we set out in how to assess a private mortgage fund manager.
The people you actually need around this
An SMSF investing in a private mortgage fund realistically needs three people in the loop:
- •A licensed financial adviser, to confirm the investment suits your fund's strategy and members
- •An accountant who knows SMSFs, to handle the wholesale certificate and the tax treatment
- •An auditor who is comfortable with the asset class and the manager's reporting
This is not a reason to avoid the investment. It is the normal machinery of running an SMSF properly, and it exists to protect the fund.
The bottom line for trustees
A private mortgage fund can be a strong fit for an SMSF chasing reliable, secured income, but the trustee obligations are real and they come first. Sole purpose, investment strategy, in-house assets, liquidity, wholesale qualification, and audit-ready reporting are all solvable, and none of them are exotic.
Work through them deliberately, with the right advisers, and the investment sits cleanly inside a well-run fund. Skip them, and you have created a compliance problem that no return makes worthwhile.
FAQs
Can an SMSF invest in a private mortgage fund?
Yes, provided the investment passes the sole purpose test, fits the fund's documented investment strategy, is made at arm's length to an unrelated manager, and the SMSF qualifies as a wholesale or sophisticated investor where the fund requires it.
Does an SMSF qualify as a wholesale investor?
It can. The common path is the net assets or gross income test, certified by a qualified accountant. For the SL Premium Income Fund, investments under $500,000 require a qualified accountant's certificate confirming wholesale or sophisticated status, and the certificate must be in place before you invest.
What is the minimum investment for the SL Premium Income Fund?
$100,000. Investments under $500,000 require a qualified accountant's certificate.
Do the in-house asset rules stop an SMSF investing in a mortgage fund?
Not where the manager and the underlying borrowers are genuinely unrelated to you and your members. The in-house asset rules broadly limit investments in or loans to related parties to 5% of fund assets. An arm's-length investment in an independent, third-party fund sits outside that, but confirm it rather than assume it.
How does this affect my SMSF's liquidity?
A private mortgage investment is committed for the term of the loan and returns capital on a defined date, not on demand. If members are in pension phase, model whether capital returns before your minimum payments fall due. A contributory structure that lets you ladder several maturities can stagger those liquidity events.
What reporting will my auditor need?
Investment statements, income distributions, and year-end valuations at market value in a form your auditor will accept. Confirm the manager provides these before investing, because you will need them every year.
