Unlock the secrets to SMSF commercial portfolio balance

Why Commercial Property in an SMSF Changes Your Diversification Profile

Commercial property held through an SMSF introduces a different diversification dynamic compared to residential investment property. Business real property under section 66 of the SIS Act remains exempt from the new LRBA restrictions that commenced 10 August 2026, which means the borrowing structure itself remains viable. The diversification question centres on whether the property genuinely reduces concentration risk or whether it creates new exposures that need to be managed alongside your existing holdings.

Consider a scenario where you hold $800,000 in Australian equities and $400,000 in a diversified managed fund within your SMSF. Adding a $900,000 commercial property under a limited recourse borrowing arrangement shifts your fund from approximately 67% equities to roughly 43% equities and 43% property once settled. That shift in asset allocation changes both your income profile and your capital growth assumptions. If the property is leased to a related party, you also introduce operational risk tied to the ongoing viability of that business relationship.

SMSF Commercial Loan Structures and Asset Concentration

The limited recourse borrowing arrangement for commercial property requires a bare trust structure where the asset is held separately until the loan is repaid. Multiple real property titles cannot be acquired under a single LRBA unless the properties are distinctly identifiable as a single asset, meaning each commercial acquisition typically requires its own borrowing arrangement and trust structure. This creates a practical constraint on how granular your commercial property diversification can be within the fund.

If you're acquiring a medical consulting suite or a small office premises, you're committing a substantial portion of the fund's borrowing capacity to a single tenant and a single location. The loan-to-value ratio for SMSF commercial loans generally sits between 60% and 70%, which means a $600,000 property requires $180,000 to $240,000 in cash or existing fund assets for the deposit and costs. That upfront capital commitment reduces liquidity and narrows the options for further diversification in the short term.

Business Real Property Definition and Portfolio Fit

Business real property generally means land and buildings used wholly and exclusively in one or more businesses, and whether a property satisfies the definition depends on its actual use at the time of acquisition. A property marketed as commercial does not automatically satisfy the definition. If the property has a residential component or mixed use that does not meet the primary production exemption criteria, it may not qualify as business real property, which removes the exemption from in-house asset rules and changes the compliance profile.

In our experience, magistrates often consider purchasing chambers or consulting rooms that include ancillary spaces such as storage or small residential components. Mixed-use properties require careful assessment based on the nature and actual use of the property, and a property with a residential component may not qualify as business real property. If the property does not qualify, and you lease it back to a related party, it becomes an in-house asset subject to the 5% limit, which can force a sale or restructure if the fund's total in-house assets exceed that threshold.

Related Party Leasing and Income Concentration

Business real property leased between the fund and a related party of the fund is excluded from the in-house asset rules, and any such lease must be made on arm's length terms at market value. If you lease the property back to your own legal practice or a family business, the rental income becomes dependent on the ongoing cash flow and viability of that single entity. This introduces a correlation between your employment income, your business income, and your superannuation income that may not exist with an arm's length commercial tenant.

As an example, a magistrate operating a part-time consultancy through a related entity leases commercial premises from their SMSF at $48,000 per annum. If the consultancy contracts or ceases, the fund loses its income stream and must either find a replacement tenant or sell the property, potentially while still servicing the LRBA. The income concentration risk is higher than holding a commercial property leased to an unrelated tenant with a longer lease term and fewer operational dependencies.

SMSF Commercial Loan Rates and Cashflow Impact

Interest rates on SMSF commercial loans typically sit higher than standard investment loans due to the limited recourse nature of the borrowing and the additional compliance requirements. The fund must generate sufficient income to service the loan from rental income and any additional contributions, without breaching contribution caps or creating liquidity issues. If the property is vacant for an extended period, the fund needs reserves or the capacity to make additional contributions to cover loan repayments.

The loan structure also affects your ability to access equity release loans for lawyers or other personal borrowing strategies, because the SMSF asset is held in a separate legal structure and cannot be used as security for personal borrowing. This can limit your flexibility if you're planning to expand a residential property portfolio or manage cashflow needs outside the fund.

LVR Constraints and Future Acquisition Capacity

The 60% to 70% LVR ceiling on SMSF commercial loans means you retain equity in the property from day one, but it also limits how much you can borrow relative to the fund's total value. If your fund balance is $1.2 million and you borrow $600,000 to acquire a $900,000 property, you've committed half the fund's existing capital to the deposit and costs. That leaves limited capacity to make further acquisitions or respond to market opportunities without waiting for the loan to reduce or the fund balance to grow through contributions and returns.

For magistrates considering SMSF loans for lawyers more broadly, the commercial loan LVR constraint is typically tighter than residential SMSF loans, where some lenders may offer up to 80% LVR depending on the property type and location. The tighter LVR on commercial property reflects the higher perceived risk and the smaller pool of lenders active in the SMSF commercial space.

Capital Growth Volatility and Illiquidity

Commercial property values are more sensitive to changes in lease terms, tenant quality, and local economic conditions than residential property. A medical suite in a regional centre may experience stable rental income while the capital value stagnates or declines if the local health precinct consolidates or a major tenant relocates. The illiquidity of commercial property also means the fund cannot quickly reallocate capital if the investment thesis changes or if other opportunities emerge.

All SMSF investments, including commercial property held under an LRBA, must be maintained at all times for the sole purpose of providing retirement benefits for SMSF members. Decisions that prioritise current-day business convenience over long-term fund performance can create compliance risk and undermine the diversification rationale for holding the property in the first place.

CGT and Exit Timing Considerations

SMSF-held commercial property benefits from the concessional tax treatment available to superannuation funds, including a potential capital gains tax discount and the nil tax rate in pension phase. If the property is sold while the fund is in accumulation phase, the gain is taxed at 15%, with a one-third discount if the asset has been held for more than 12 months, resulting in an effective rate of 10%. If the fund has moved to pension phase, the gain may be tax-free.

The timing of a sale relative to your retirement and the fund's transition to pension phase can materially affect the after-tax return. If you're forced to sell the property to rebalance the portfolio or meet liquidity needs before entering pension phase, you'll pay tax on the gain. This creates a tension between maintaining diversification and optimising tax outcomes, particularly if the property is acquired within 10 years of your planned retirement.

Balancing Commercial Property with Liquid Assets

A diversified SMSF portfolio should retain sufficient liquidity to meet member benefit payments, fund expenses, and loan repayments without being forced to sell illiquid assets at inopportune times. If commercial property under an LRBA represents more than 50% of the fund's total assets, the fund's ability to respond to cashflow needs or market dislocations is materially constrained.

In practice, this means holding a buffer in cash, term deposits, or liquid managed funds equivalent to at least 12 to 24 months of loan repayments and fund expenses. That buffer reduces the income drag from holding cash but provides the flexibility to manage vacancy periods, interest rate rises, or unexpected compliance costs without triggering a distressed sale.
