Buying property through an SMSF: what it actually costs and what you can't do

More than 600,000 self-managed super funds in Australia hold residential or commercial property, and a steady share of new SMSFs are set up specifically to do it. The strategy is real and it can be tax-efficient. It is also wrapped in restrictions that do not apply to a property bought in your personal name, and the ones that catch people out are not the headline rules. They are the small print buried in the borrowing arrangement and the sole-purpose test.

What an SMSF can and cannot buy

An SMSF can hold residential investment property, commercial property, and in some cases rural land. What it cannot do is almost more important. The fund cannot buy a residential property from a related party, which rules out buying mum's unit at market value to help her downsize. No member of the fund or any relative can live in the property. No member or relative can rent it, even at full market rent. The property must be held purely as an investment owned by the trustee on behalf of the members' retirement balances.

Commercial property is the one carve-out where related-party rules loosen. A fund can buy commercial premises from a member and lease it back to that member's business, provided the rent is at arm's-length market rate and documented with a formal lease. This is the single most common reason small business owners set up an SMSF property strategy: the fund owns the warehouse or the consulting suite, the business pays rent into the fund instead of to a third-party landlord, and the rent compounds tax-effectively inside super.

The sole-purpose test, and why it eats good ideas

Every decision a trustee makes has to satisfy what the SIS Act calls the sole-purpose test: the fund exists to provide retirement benefits to its members, not present-day lifestyle benefits. This sounds soft until you try to apply it. Buying a beach house the family uses for one weekend a year fails. Buying a ski apartment with a free week stripped out of the lease fails. Renovating to a higher spec than market because you like the kitchen fails. The ATO has audited SMSFs back to a zero-tax determination over breaches that started as small favours to the members.

Borrowing inside super: the LRBA

Since the 2007 rule change, an SMSF can borrow to buy a single asset under a Limited Recourse Borrowing Arrangement. Two features make an LRBA different from a normal investment loan. First, the lender's recourse is limited to the property itself: if the loan defaults, the lender cannot chase the rest of the fund's assets. Second, the property is held in a separate bare trust during the loan, with the SMSF as beneficiary, and only transfers into the fund directly once the loan is paid out.

Lenders price the extra structure into the rate. A typical SMSF loan in 2026 sits around 60 to 70% LVR (versus 80 to 90% on a personal investment loan) at an interest rate roughly 1 to 1.5 percentage points above retail. Big-four banks have largely exited the segment; specialist non-bank lenders dominate. One property, one loan, one bare trust. If the fund wants to buy a second property with debt, the whole structure repeats.

The no-improvement rule (the one that catches people)

While the LRBA is in place, the property is treated as a single acquirable asset. Trustees can repair and maintain it. They cannot improve it. Replacing a broken hot water system with a like-for-like model is a repair. Replacing it with a heat pump and adding solar is an improvement. Repainting is fine. Adding a granny flat, extending the kitchen, or rebuilding the bathroom to a higher spec is not. Improvements during the LRBA can trigger an in-house asset breach and put the fund's complying status at risk.

The fix is one of two things. Pay out the loan first, then improve. Or fund the improvement out of separate fund cash, not borrowed money, and document carefully that the work is a repair rather than an enhancement. Plenty of trustees only learn the rule when their accountant queries an invoice at audit time, by which point the work is done and the unwind is messy.

What it actually costs

Setting up an SMSF to hold property runs roughly $3,000 to $5,000 once you add a corporate trustee, the bare trust deed, and the legal work to document the LRBA. Annual running costs sit around $2,000 to $4,000 covering accounting, the mandatory independent audit, and ASIC fees on the corporate trustee. The audit alone is typically $1,500 a year and is non-negotiable regardless of fund size.

On a $400,000 fund balance these costs eat roughly 0.5 to 1.0% of assets a year before the property even settles. On a $1.5 million fund they fade into background noise. The commonly-cited threshold for an SMSF property strategy to make sense on costs alone is somewhere around $300,000 to $400,000 of starting balance, and that assumes the trustees are willing to do real ongoing work rather than treat the fund like a retail super product.

Worked example: commercial property, fund leases to business

A fund with a $400,000 balance buys a $700,000 commercial suite with a $300,000 LRBA at 7.5% interest-only. The member's business signs a market-rate lease at $42,000 a year (a 6% gross yield, plausible for regional commercial in 2026).

Annual cash flow inside the fund: rent $42,000 in, interest $22,500 out, council rates and insurance and management around $8,000 out. Net cash contribution to the fund is $11,500 a year on top of any concessional contributions the members are still making. The principal sits as equity build inside the bare trust, not as cash, which is why liquidity matters (more on that below).

The tax treatment is where the structure earns its keep. Rental income inside an SMSF in accumulation phase is taxed at 15%, not the member's marginal rate of 32 to 45%. On the $11,500 net rental result, the fund pays roughly $1,725 in tax versus $4,255 to $5,175 if the same property were held in personal name at the 37 to 45% bracket. Across a ten-year hold that gap compounds.

Capital gains tax is the bigger lever. An SMSF in accumulation phase pays 15% on capital gains, dropped to 10% if the asset was held more than twelve months. Once members move into pension phase after age 60 and the fund is paying a retirement income stream, the rate on both rental income and capital gains drops to zero on assets supporting the pension. A property bought through the fund at 50 and sold at 65 in pension phase pays no CGT at all, which is the headline number that drives most of these strategies.

The cons most explainers gloss over

Concentration risk is the obvious one. A $400,000 fund with a $700,000 property is roughly 95% real estate by value, with the residual cash mostly going to loan repayments and running costs. There is no diversification cushion left if the tenant leaves or the local market dips.

Liquidity is the less-obvious one and the one that bites at retirement. Once the fund starts paying a pension to its members, it has to meet a minimum drawdown each year (4% of balance at age 60 to 64, scaling up to 14% above age 95). A single property cannot be sliced off in 4% chunks. If the only liquid asset is the property, the trustee may be forced to sell at a bad time to fund the pension. The cleaner versions of this strategy keep meaningful cash and listed assets alongside the property for exactly this reason.

Negative gearing does not work the way it does outside super. Any rental loss stays inside the fund and offsets other fund income; it cannot flow through to a member's personal tax return. For a high-income member the deductibility of a loss at 15% inside the fund is much less valuable than the same loss at 45% in personal name. If the case for the property depends on personal-marginal-rate negative gearing, the SMSF is the wrong wrapper.

Who this actually suits

Three groups tend to come out ahead. Pre-retirees in their late 40s to early 60s with at least $300,000 to $500,000 in super and a 10 to 15-year horizon to pension phase get the full benefit of the 15% accumulation rate followed by the 0% pension-phase rate. Small business owners who want to buy their own commercial premises and pay rent to their own fund rather than to a landlord turn an existing business expense into retirement savings. High-income earners already at the concessional contribution cap who want tax-efficient property exposure get a second tax-advantaged channel beyond their personal investment portfolio.

Where to model this for your own numbers

The cash-flow side of any SMSF property decision starts with the same question as a personal-name purchase: what is the net yield after real outgoings, and what does the loan cost. The rental yield calculator and the mortgage calculator give you both, and you can adjust the rate up by 1.0 to 1.5 percentage points to model the LRBA premium over a retail investment loan. The exit side is where the SMSF tax structure does most of its work, and the CGT worked example is the cleanest way to see what changes when the rate drops from a personal 37% marginal to 10% in accumulation or 0% in pension phase on the same gain.

Pair that with the negative gearing piece if you are weighing the SMSF route against buying in personal name. The trade-off is genuine: personal name gives you full marginal-rate deductibility on the loss but full marginal-rate CGT on the gain; SMSF gives you 15% on income and 0 to 15% on gains, but the loss only offsets at 15% if it offsets at all. For a top-bracket earner planning a long hold into pension phase, the SMSF maths usually wins. For a mid-bracket earner with a short horizon and an appetite for negative gearing right now, it usually does not.

Two final caveats. SMSFs are heavily regulated and trustees carry personal liability for compliance breaches; the audit trail matters as much as the investment thesis. And SMSF property is one of the few areas where paying for a specialist (an SMSF-experienced accountant, a financial adviser with the SMSF accreditation, and a lawyer to draft the bare trust properly) is genuinely worth the fee. The cost of getting the structure right is small against the cost of an in-house asset breach unwinding the fund's complying status.
