How Lenders Calculate SMSF Loan Serviceability
Lenders assess an SMSF's ability to service a loan by looking at two main income streams: fund contributions and rental income from the property being purchased. Unlike a personal home loan where your salary does the heavy lifting, an SMSF loan serviceability assessment hinges on whether the fund can meet repayments from these sources without breaching super rules or running out of cash.
The calculation method varies between lenders, but most will require rental income to cover at least 100 to 120 per cent of the loan repayment, with concessional and non-concessional contributions used to fill any gap. Some lenders will accept contributions as the primary servicing source if the fund has a strong history of regular deposits and the members are still working. Others take a more conservative view and will only lend where rental income alone can service the debt.
Consider a fund purchasing a small commercial unit in Eight Mile Plains. The property generates $32,000 in annual rent and the fund receives $60,000 in combined member contributions each year. If the loan repayment is $28,000 annually, rental income covers the commitment with room to spare. The lender will also want to see consistent contribution patterns over at least two financial years and confirm that members are below their contribution caps and have capacity to continue contributing.
Rental Income: What Lenders Will and Won't Accept
Rental income must be verified and sustainable. Lenders will request a signed lease agreement and evidence of rent paid into the fund's bank account, typically covering three to six months. They will not accept projected or estimated rental income without a tenant in place at the time of settlement.
Where a property is leased to a related party of the fund, such as a member's business, the lease must be at market rent and on arm's length terms. The SMSF loan will be treated as financing business real property, which is the only type of real property an SMSF can acquire under a Limited Recourse Borrowing Arrangement entered into from 10 August 2026 onward. Related party leases attract additional scrutiny from both lenders and the ATO, and the rent must reflect what an unrelated tenant would pay for the same premises.
Some lenders will apply a vacancy factor or rental stress test, typically reducing the rental income by 10 to 15 per cent to account for potential vacancies or non-payment. If the serviceability assessment still stacks up after that discount, the loan is more likely to be approved. This is particularly relevant in areas like Eight Mile Plains where commercial tenancies can turn over as businesses relocate or downsize.

Contributions: How Much Can You Rely On Them?
Concessional contributions from employer super guarantee payments and salary sacrifice, along with non-concessional after-tax contributions, can be included in a serviceability assessment if they are regular and verifiable. Lenders will ask for at least two years of SMSF financial statements and tax returns to confirm contribution history.
For the current financial year, the concessional contribution cap sits at $32,500 per member and the non-concessional cap is $130,000. If a member's total super balance was below $1.84 million on 30 June of the previous year, they may access the bring-forward arrangement allowing up to $390,000 in non-concessional contributions over three years. Where the balance was between $1.84 million and $1.97 million, the bring-forward limit is $260,000 over two years. Members with a total super balance at or above the general transfer balance cap cannot make non-concessional contributions.
A fund relying heavily on contributions to service a loan carries more risk in the lender's eyes. If a member loses their job, retires, or reaches the transfer balance cap and stops contributing, the fund's income drops sharply. Most lenders will factor in age and employment status when assessing contribution-based serviceability, and some will not lend at all if members are within five years of retirement.
Business Real Property: The Only Option for New SMSF Loans
Any SMSF loan over real property entered into from 10 August 2026 must be used to purchase business real property. The property must be used wholly and exclusively in one or more businesses at the time the loan is entered into and for the entire life of the arrangement. Residential investment properties that are not business real property can no longer be financed under an SMSF Limited Recourse Borrowing Arrangement, though funds can still buy them outright with cash.
Business real property includes commercial premises such as offices, warehouses, retail shops, and industrial units. It also covers properties used in primary production, provided any dwelling on the land sits on no more than two hectares and the main use is not domestic. A commercial zoning or description does not automatically mean a property qualifies. What matters is actual use.
In a scenario where a fund in Eight Mile Plains purchases a small office tenanted by an accounting firm, the property qualifies as business real property and an SMSF loan can be used. If that tenant vacates and the trustee actively markets the premises for lease, the property does not stop being business real property during that search period. However, if the trustee decides to leave the property vacant indefinitely or converts it to another use, the fund may breach the borrowing rules and face compliance action.
LVR and Deposit Requirements for SMSF Commercial Loans
Loan-to-value ratios for SMSF commercial property loans are typically lower than for standard investment loans. Most lenders will lend up to 70 per cent of the property value, meaning the fund must contribute at least 30 per cent as a deposit plus settlement costs. Some lenders cap their LVR at 60 per cent, particularly where the property is in a regional area or has a single tenant on a short lease.
The deposit must come from the fund's existing cash reserves or new contributions made before settlement. Borrowed funds cannot be used to pay the deposit, and the lender will require evidence that the deposit amount has been held in the fund's bank account for at least three months. This is to ensure the money is genuinely part of the fund and not sourced from an undisclosed loan or related party payment.
For a $400,000 commercial property in Eight Mile Plains, a 70 per cent LVR means a loan of $280,000 and a deposit of $120,000. Add approximately $15,000 to $20,000 for stamp duty, legal fees, and loan establishment costs, and the fund needs around $140,000 in available cash. Members can make additional contributions to meet this requirement, provided they remain within their caps and the fund's trust deed allows it.
Refinancing an Existing SMSF Loan After 10 August 2026
An SMSF can refinance a Limited Recourse Borrowing Arrangement entered into before 10 August 2026, even if the property is residential and not business real property. The new borrowing rule does not apply to refinancing or maintaining an older arrangement, provided the property being refinanced is the same asset or assets and the new loan amount does not exceed the outstanding balance.
Where the fund entered into the loan on or after 10 August 2026 over business real property, any refinance must occur while the property still meets the business real property definition. If the property stops being used wholly and exclusively in a business during the life of the loan, the fund breaches the borrowing rules and cannot refinance under an LRBA.
Refinancing serviceability is assessed in the same way as a new loan. The lender will review current rental income, contribution history, fund financial statements, and the property's valuation. If rental income has dropped or contributions have become irregular, the fund may not meet the new lender's criteria even though it has been servicing the existing loan without issue.
What Happens If Your Fund Can't Service the Loan?
If rental income falls or contributions stop and the fund cannot meet loan repayments, the consequences depend on the loan structure. Under a Limited Recourse Borrowing Arrangement, the lender's recourse is limited to the property held in the holding trust. The lender cannot pursue other fund assets, though a related party guarantor may be liable if they provided personal security.
Missed repayments can lead to default, and the lender may ultimately sell the property to recover the debt. This crystallises any capital loss and may leave the fund with reduced assets and a poor credit history. It also attracts the attention of the ATO, particularly if the fund has breached contribution caps, made non-arm's length payments, or failed the sole purpose test.
Prevention is the focus for most SMSF mortgage brokers. Before committing to a loan, the fund's trustees should model different scenarios: what happens if the tenant leaves, if rent drops by 20 per cent, or if a member retires and stops contributing. The fund should also hold a cash buffer equivalent to at least six months of loan repayments to manage short-term disruptions without defaulting.
Tax Treatment of SMSF Rental Income and Contributions
Rental income earned by an SMSF in accumulation phase is taxed at 15 per cent. If the fund is paying a retirement phase pension and the property supports that pension, the rental income may be exempt under the exempt current pension income rules, depending on whether the fund uses the segregated or proportionate method.
Concessional contributions are also taxed at 15 per cent when received by the fund, or 30 per cent if a member's income and concessional contributions exceed $250,000 in a financial year. Non-concessional contributions are not taxed on entry, as they are made from after-tax dollars. These tax settings affect the fund's net cash flow and must be factored into any borrowing capacity assessment.
From 1 July 2026, Division 296 tax applies to members whose total super balance exceeds $3 million. An additional 15 per cent tax is levied on the proportion of total super earnings that relates to the amount above that threshold, and a further 10 per cent applies to amounts above $10 million. Importantly, the outstanding balance of a Limited Recourse Borrowing Arrangement is never included in a member's total super balance for Division 296 purposes, though it may be included for other purposes depending on when the loan was entered into and who the lender is.

Frequently Asked Questions
Can an SMSF use member contributions to service a commercial property loan?
Yes, most lenders will accept regular concessional and non-concessional contributions as part of the serviceability assessment, provided the fund has a consistent contribution history over at least two years. Lenders typically require rental income to cover 100 to 120 per cent of the loan repayment, with contributions used to fill any gap or provide additional buffer.
What type of property can an SMSF finance under a loan from 10 August 2026?
Only business real property can be financed under a Limited Recourse Borrowing Arrangement entered into from 10 August 2026. The property must be used wholly and exclusively in one or more businesses at the time the loan is entered into and throughout its life. Residential investment properties that are not business real property cannot be financed, though they can still be purchased with cash.
Can an SMSF refinance a residential property loan entered into before August 2026?
Yes, an SMSF can refinance a Limited Recourse Borrowing Arrangement over residential property if the loan was entered into before 10 August 2026. The new borrowing rule does not apply to refinancing or maintaining older arrangements, provided the property and loan amount remain consistent.
What deposit does an SMSF need for a commercial property loan?
Most lenders require a deposit of at least 30 per cent of the property value, as loan-to-value ratios for SMSF commercial loans are typically capped at 70 per cent. The deposit must come from the fund's existing cash or new contributions, and lenders usually require proof the funds have been held in the SMSF account for at least three months.
What happens if an SMSF cannot meet loan repayments?
If the fund defaults, the lender's recourse is limited to the property held in the holding trust under a Limited Recourse Borrowing Arrangement. The lender may sell the property to recover the debt, but cannot pursue other fund assets. Default can result in capital loss, credit history damage, and potential ATO compliance action.
