SMSF Loan Refinance: What Not to Miss on Serviceability

Serviceability Assessment Works Differently for SMSF Refinance

Lenders assess SMSF loan serviceability using the fund's rental income and contribution history, not your personal income. A fund refinancing an investment property in Rockingham needs to demonstrate that rental returns and member contributions can cover the proposed loan repayments at the lender's assessment rate, which sits above the advertised rate. The fund itself is the borrower, so your salary and household expenses don't enter the calculation the way they would for a standard home loan.

Consider a fund holding a residential property near Churchill Park that was purchased under a Limited Recourse Borrowing Arrangement before July 2026. The property generates $480 per week in rent, and two members contribute $15,000 annually to the fund. When refinancing, the lender applies a serviceability buffer to the proposed interest rate and calculates whether the fund's income can meet repayments under that stressed scenario. Most lenders require the fund to service the loan at a rate 2.5% to 3% above the actual rate, meaning a loan offered at 6.2% would be assessed at around 9%. If the numbers don't stack up under that assessment, the application fails regardless of how strong your personal financial position might be.

Why Your Fund's Rental Yield Matters More Than Equity

Rental income is the primary serviceability metric for an SMSF residential loan refinance. Lenders typically expect the property to generate a rental yield sufficient to cover at least 110% of the assessed loan repayments, though some accept lower coverage if the fund has a strong contribution history. A property in Rockingham's established suburbs might yield 4% to 5% on current values, which can make refinancing more challenging if the loan-to-value ratio is high or if rental markets have softened since the original purchase.

Funds that purchased coastal properties near Shoalwater or Warnbro during the rental squeeze a few years ago often enjoyed yields above 5.5%. Those same properties may now yield closer to 4.5% as rental growth has slowed and property values have adjusted. If your fund is refinancing and the yield has dropped, the lender may require a larger principal reduction, additional contributions, or both to meet serviceability.

Member Contributions and How Lenders Treat Them

Lenders accept concessional and non-concessional member contributions as part of the fund's income, but they apply different treatment depending on consistency. Regular contributions over at least two financial years carry more weight than a single large contribution made shortly before the refinance application. If your fund shows $20,000 in combined contributions each year for the past three years, lenders will factor that into serviceability. A one-off $60,000 contribution in the current year is less likely to be accepted at full value.

In our experience, funds that rely heavily on member contributions to meet serviceability often face questions about sustainability. Lenders want to see that contributions align with the members' capacity to maintain them over the life of the loan, particularly if members are approaching retirement age and contribution capacity may decline.

SMSF Fixed Rate Expiry and Revert Rate Risk

Many SMSF loans taken out between 2021 and 2023 are now expiring from fixed terms and reverting to variable rates that sit well above the original fixed rate. If your fund's loan is reverting to a rate above 7%, refinancing may deliver a lower rate and improved cash flow. The challenge is that revert rates are often not disclosed until shortly before expiry, and refinancing an SMSF loan takes longer than a standard home loan due to compliance checks and trustee documentation.

Refinancing also allows you to access features that many SMSF lenders did not offer during the fixed rate period, including offset accounts. An offset account linked to your fund's loan can reduce interest costs without triggering non-arm's length income provisions, provided the account is offered by an authorised deposit-taking institution and meets the ATO's current guidance.

What Changed for Residential LRBA Refinancing in July 2026

The Treasury Laws Amendment (Tax Reform No. 1) Act 2026 prohibits new residential LRBAs, but refinancing an existing residential loan entered into before July 2026 remains permissible. The legislation allows funds to maintain or refinance existing residential arrangements without falling under the new prohibition. The ATO has not yet updated its guidance on what constitutes a refinancing arrangement versus a new LRBA under the post-commencement rules, but Practical Compliance Guideline PCG 2016/5 continues to apply.

A significant change to the terms or conditions of your LRBA could end the existing arrangement and trigger the new rules. Refinancing that is inconsistent with the original arrangement, borrowing to acquire an asset not contemplated under the original arrangement, or changes to the ultimate beneficiaries of the arrangement may all result in the ATO treating the refinance as a new LRBA. If that occurs, the residential prohibition applies and the arrangement becomes non-compliant. This is why working with a specialist SMSF refinance broker is particularly important for funds holding residential property.

Commercial LRBA Refinancing Operates Under Different Rules

If your fund holds a commercial property under an LRBA, the residential prohibition doesn't apply and refinancing continues as it did before July 2026. Compliance conditions still apply, including that the refinanced loan must relate to the same single acquirable asset, maintain the limited recourse character of the original arrangement, and meet arm's length terms consistent with PCG 2016/5. Commercial properties in Rockingham's industrial precincts near Latitude 32 or along Rockingham Road are eligible for refinancing without the additional constraints that now apply to residential holdings.

Serviceability for commercial LRBAs is assessed using the property's lease income rather than residential rental income. A commercial lease with a term of three years or more and a creditworthy tenant will carry more weight with lenders than a short-term residential tenancy. Lenders also assess the lease structure, outgoings recovery, and any options to renew when determining serviceability.

Arm's Length Terms and Safe Harbour Interest Rates

Any SMSF loan refinance must meet arm's length terms to avoid non-arm's length income provisions. The ATO publishes safe harbour interest rates under PCG 2016/5, updated annually, which apply to both real property and listed securities held under an LRBA. Income from an arrangement that does not meet arm's length terms may be assessed as non-arm's length income and taxed at the highest marginal rate, which effectively eliminates the concessional tax treatment that makes SMSFs attractive.

When comparing lenders, the interest rate is only one factor. The loan terms must also reflect what would be available in a commercial transaction between unrelated parties. A related party lender offering a rate well below the safe harbour rate, or terms that include unusual deferrals or waivers, may trigger ATO scrutiny. If you're refinancing to reduce your rate, make sure the terms remain defensible as arm's length.

Limited Recourse and Personal Guarantees

In the event of a default, the lender's recourse against the SMSF trustees must be limited to the asset being acquired under the arrangement. This limited recourse character must be maintained through any refinancing. A related party may provide a personal guarantee to the lender, but their recourse must also be limited to the asset under the arrangement and not any other SMSF assets. Some lenders accept limited recourse terms more readily than others, and funds refinancing from a lender that required a full recourse guarantee may find better terms available elsewhere.

Rockingham-based funds holding property interstate should also confirm that the refinancing lender is comfortable with the asset location and fund structure. Not all lenders offer SMSF loans in every state, and some apply different loan-to-value ratios or serviceability overlays depending on the property's location.

Application and Settlement Timelines

SMSF loan refinancing typically takes four to six weeks from application to settlement, longer than a standard home loan refinancing process. The lender requires trustee resolutions, an updated trust deed, member consent documentation, and confirmation that the LRBA structure remains compliant. If your fund's trust deed has not been updated to reflect current superannuation law, some lenders will require an updated deed before proceeding.

Settlement also requires coordination between the fund's accountant, the lender, and the incoming and outgoing lenders' solicitors. Funds refinancing should allow enough time to avoid a situation where the fixed rate expires and the loan reverts to a higher variable rate while the refinance is still in progress. Starting the refinance process at least eight weeks before a fixed rate expiry gives you room to address any compliance or documentation issues without rushing.
