SMSF Serviceability & Common Mistakes to Avoid

Lenders assess SMSF borrowing capacity differently to standard investment loans.

Your fund needs to demonstrate it can service the loan using contributions you're legally allowed to make, plus any rental income the property generates. That assessment became considerably more important for Helensvale investors after 10 August 2026, when new Limited Recourse Borrowing Arrangements for residential property were prohibited. Commercial property remains available, and the serviceability principles apply to both.

How Lenders Calculate SMSF Borrowing Capacity

Lenders assess two income streams when determining how much your SMSF can borrow: the concessional and non-concessional contributions you can make within legal caps, and the rental income the property will generate.

From 1 July 2026, the concessional contributions cap is $32,500 per annum and the non-concessional cap is $130,000 per annum. If your total superannuation balance was below $1.84 million on 30 June of the previous year, you may access the bring-forward arrangement and contribute up to $390,000 in non-concessional contributions over three years. Lenders typically assess your capacity to make these contributions based on your taxable income, employment stability, and existing super balance. They do not assume you will max out your caps every year unless you can demonstrate a consistent contribution history.

Rental income is assessed at around 80 percent of the market rent to allow for vacancy periods and maintenance costs. Consider a Helensvale investor with a fund holding a commercial property near Westfield Helensvale. The property leases for $48,000 per annum. The lender assesses rental income at $38,400 and requires evidence of concessional contributions averaging $25,000 per annum over the previous two years. Total assessed income is $63,400. At a serviceability rate of 8.5 percent with principal and interest repayments, the fund can service a loan of approximately $580,000 at an LVR of 70 percent. The same fund attempting to borrow for residential property before the August ban would have faced identical serviceability criteria but with residential rental yields, which in Helensvale typically sit between 4.5 and 5 percent gross.

The August 2026 Residential Ban and What It Means for Helensvale Buyers

New LRBAs for residential property are no longer permitted from 10 August 2026.

The Treasury Laws Amendment (Tax Reform No. 1) Act 2026 inserted a condition requiring that property acquired under an LRBA must meet the business real property definition under section 66 of the SIS Act. Residential property does not meet that definition. The ban applies regardless of whether the dwelling is newly constructed or an existing home. Contracts exchanged before 10 August 2026 are protected, even if settlement occurs afterward. Existing LRBAs over residential property remain in place and can be refinanced under certain conditions.

For Helensvale residents with SMSFs, this closed off borrowing to acquire houses and units in the suburb. If your fund already holds residential property under an LRBA entered into before the ban, no action is required. You can continue to service the loan, refinance it if needed, and hold the property until retirement. You cannot use borrowed funds to acquire additional residential property. You can still purchase residential property outright if your fund has sufficient cash, provided the property is not acquired from a related party and is not occupied by a member or related party.

Commercial Property Serviceability and the Business Real Property Test

Commercial property LRBAs remain available where the property satisfies the business real property definition.

Business real property means land and buildings used wholly and exclusively in one or more businesses. The business does not need to be carried on by the SMSF or a related party. A commercial premises leased to an unrelated tenant operating a business qualifies. Mixed-use properties can qualify if the main use is not domestic or private and any dwelling occupies no more than 2 hectares. Vacant land not currently used in a business does not qualify at the time of acquisition.

Helensvale sits within a growth corridor with commercial property available near the M1 interchange and around the Westfield Helensvale precinct. Lenders assess commercial property serviceability using the same contribution and rental income method but apply different LVR caps. Most SMSF lenders restrict commercial property LRBAs to 70 percent LVR, with some capping at 60 percent depending on property type and lease strength. A property leased to a national tenant on a five-year lease will typically achieve a higher LVR than a property leased to a single operator on a short-term agreement.

Serviceability is assessed using the lease income at 80 percent, plus contributions. A fund member earning $120,000 per annum and contributing $25,000 in concessional contributions, with a commercial property generating $55,000 in annual rent, has assessed income of $69,000. That supports a loan of approximately $630,000 at 70 percent LVR with a serviceability buffer applied at current variable rates. The same principles apply whether the property is a warehouse, office suite, or retail tenancy.

Contribution Caps and Division 296 Tax Impact on Borrowing Capacity

Lenders adjust their assessment where a member's total superannuation balance exceeds $3 million.

Division 296 tax applies from 1 July 2026 at 15 percent on earnings attributable to balances above $3 million, and an additional 10 percent on earnings above $10 million. Outstanding LRBA amounts entered into on or after 1 July 2018 are included in the total superannuation balance calculation where the LRBA is with an associate of the fund or where the member has satisfied a condition of release with a nil cashing restriction. This changes the tax treatment of fund earnings and may reduce the net rental income available to service the loan.

Lenders typically require funds affected by Division 296 tax to demonstrate higher contribution capacity or stronger rental yields to offset the additional tax liability. A Helensvale-based SMSF with a member holding a $3.8 million balance and acquiring commercial property at $1.2 million with a $720,000 loan will have the loan amount included in the total balance for Division 296 purposes. The additional 15 percent tax applies to a portion of earnings, reducing net income. The member may need to demonstrate capacity to make higher contributions or accept a lower LVR to satisfy serviceability.

Where your balance sits close to the $3 million threshold, the decision to borrow should factor in the likelihood of crossing into Division 296 territory within the loan term. This is not a reason to avoid borrowing, but it does require realistic modelling of contribution capacity over a five to ten year period.

Refinancing Existing Residential LRBAs After the Ban

Existing residential LRBAs can be refinanced under the grandfathering provisions.

The residential ban does not apply to maintaining or refinancing a borrowing under an arrangement entered into before 10 August 2026. As at 2 July 2026, the ATO had not published updated guidance on what constitutes a refinancing versus a new arrangement. Under existing ATO guidance, a significant change to the terms or conditions of an LRBA ends the arrangement and begins a new one. Circumstances that may trigger this include refinancing inconsistent with the original arrangement, borrowing to acquire an asset not contemplated under the original loan, or changes to the ultimate beneficiaries.

For practical purposes, switching lenders to secure a lower SMSF variable rate or moving from a fixed to variable rate is generally treated as a refinance of the existing arrangement, provided the loan amount does not increase beyond capitalised costs and the asset remains the same. Increasing the loan to fund capital improvements, or consolidating multiple properties under a single loan where they were originally held under separate LRBAs, may be treated as a new arrangement and could breach the residential ban.

If you hold a residential LRBA in Helensvale and want to refinance, document the original loan terms and discuss with your SMSF mortgage broker whether the proposed refinance falls within the grandfathering provisions. Practical Compliance Guideline PCG 2016/5 sets out arm's length terms for SMSF LRBAs, including safe harbour interest rates updated annually by the ATO. A refinance that does not meet arm's length terms may result in income being assessed as non-arm's length income and taxed at the highest marginal rate.

Related Party Leasing and Arm's Length Terms for Commercial Property

Business real property leased between the fund and a related party is excluded from the in-house asset rules.

This allows your SMSF to acquire commercial property under an LRBA and lease it to a business you or a related party controls. The lease must be made on arm's length terms at market value. This means the rent charged must reflect what an unrelated tenant would pay for the same property in the same location with comparable lease conditions. The ATO applies significant scrutiny to related party leases, and failure to meet arm's length terms can result in the income being taxed at the top marginal rate.

Consider a Helensvale-based SMSF that acquires a warehouse near the Pacific Motorway under an LRBA and leases it to a family company operating a logistics business. The fund borrows $800,000 at 70 percent LVR, with the property valued at $1.14 million. The lease is set at $72,000 per annum based on comparable leases in the area. The company pays rent monthly, and the lease includes annual CPI increases and standard outgoings clauses. The lender assesses rental income at 80 percent, contributing $57,600 to serviceability, with the balance covered by member contributions of $30,000 per annum. The arrangement meets arm's length terms and qualifies for the business real property exception.

If the rent is set below market value to assist the related party business, the ATO may treat the discount as non-arm's length income. The entire rental income, not just the discount, is then taxed at 47 percent rather than the concessional 15 percent rate. For this reason, obtaining an independent valuation and market rental assessment before entering a related party lease is non-negotiable.
