Buying an Investment property inside a self-managed super fund (SMSF) using borrowed money is possible — but the rules that make it possible are strict, and they shape every step of the purchase. SMSFs are generally prohibited from borrowing at all. The main exception is a limited recourse borrowing arrangement (LRBA), a tightly structured mechanism that lets a fund borrow to buy a single asset while quarantining the lender's rights ATO limited recourse borrowing arrangements. If you are contemplating a geared property purchase in your SMSF, understanding how the LRBA rules constrain the deal is essential before you sign anything.

The general ban on borrowing, and the LRBA exception

Superannuation law starts from a prohibition: an SMSF must not borrow money, subject to limited exceptions. The most significant is the LRBA ATO limited recourse borrowing arrangements. Under an LRBA, the fund borrows to acquire a single acquirable asset (or a collection of identical Assets with the same market value), which is held in a separate holding trust until the Loan is repaid. The arrangement is “limited recourse”, meaning the lender's rights on default are limited to that asset alone — the fund's other assets are protected ATO rules on assets under an LRBA.

“Single acquirable asset” shapes the purchase

The single-asset requirement has real consequences for property. Each LRBA must relate to one asset, so buying two separate titles usually needs two arrangements. The asset held in the holding trust must remain the same asset for the life of the loan — you cannot use borrowed funds to change its fundamental character ATO rules on assets under an LRBA. And the asset must be one the fund could otherwise legally acquire and hold: a fund cannot use an LRBA to sidestep the other investment rules.

Repairs yes, improvements no

A frequently misunderstood rule concerns what you can do to the property. Borrowed money under an LRBA can be used to maintain or repair the asset, but it cannot be used to improve it. Improvements may be funded from the fund's own cash, but they must not result in the asset becoming a different asset ATO rules on assets under an LRBA. Turning a house into a block of units, for example, changes the asset and breaches the rules. This is a common trap for trustees hoping to add value through renovation.

Related-party lenders and arm's length terms

Funds sometimes borrow from a related party — often the members themselves — rather than a bank. This is permitted, but the loan must be on arm's length commercial terms. If the terms are more favourable than a commercial loan, the income from the arrangement can become non-arm's length income (NALI) and be taxed at the highest marginal rate ATO investment restrictions. The ATO has published “safe harbour” terms that, if met, mean a related-party LRBA is treated as arm's length. Straying from those terms without independent evidence is risky.

Who lends, and at what cost

Not every lender offers SMSF loans, and those that do typically require larger deposits and charge higher interest than for a personal purchase, because the limited-recourse structure gives them less security. Establishment costs are also higher: you need a separate holding trust and its trustee, specific loan documents, and usually legal and advice fees. These costs, and the ongoing loan repayments, come out of the fund. Trustees should model the arrangement on realistic assumptions — including periods of vacancy and Interest Rate rises — rather than best-case rent, because the fund must keep meeting repayments even when the property is empty.

What limited recourse really protects

The “limited recourse” feature is genuinely valuable but often misread. It means that if the fund defaults, the lender can take the single asset held in the holding trust but cannot pursue the fund's other assets to recover a shortfall ATO limited recourse borrowing arrangements. That protects the rest of your retirement savings from a bad property outcome. It does not, however, protect you from the ordinary risks of gearing: if the property falls in value or sits vacant, the fund still bears that loss and still owes the repayments. Limited recourse limits the lender's reach; it does not remove investment risk.

An exception is not a free pass

The most important mindset is that an LRBA is an exception to one rule, not an exemption from all the others. A geared property must still satisfy the sole purpose test, be dealt with at market value, respect the in-house asset limits, and — if bought from or leased to a related party — meet those separate requirements too ATO investment restrictions. Residential property, in particular, generally cannot be acquired from a related party or lived in or rented by members or their relatives, even under an LRBA.

A hypothetical example

Hypothetical: The Osei SMSF wants to buy a $600,000 residential investment unit with a $360,000 loan. It sets up a holding trust, borrows on limited-recourse terms, and buys the single unit from an unrelated vendor. The fund can use its own cash to repaint and replace the kitchen (repairs and maintenance), but it cannot use borrowed money to add a second storey, and it cannot subdivide the title into two units while the LRBA runs, because that would change the asset. The members cannot rent the unit themselves. Loan repayments must come from the fund's rent and contributions, so the trustees keep a cash buffer to avoid missing repayments.

Weigh the risks before gearing

Gearing magnifies both gains and losses, and it concentrates the fund in one asset, so Liquidity and Diversification deserve careful thought and documentation in the fund's investment strategy ATO SMSF investment requirements. LRBA rules have also been an area of legislative attention over time, so confirming the current requirements before you act is wise. A geared property can suit some funds, but the structure is unforgiving of mistakes: the single-asset rule, the no-improvement rule and the related-party terms all have to be right from the outset. Get advice from an SMSF specialist, model the Cash Flow including loan repayments, and make sure the deal fits the rules before it fits your ambitions. The extra cost of getting the structure reviewed before settlement is small next to the cost of unwinding a non-compliant arrangement afterwards.
