Variable Rate Loans for SMSF Property Purchases

Variable rate loans remain the most used structure for SMSF property purchases.

The offset account and repayment flexibility typically outweigh the appeal of fixed rate certainty, particularly when trustees need to manage cash flow between member contributions, rental income, and loan servicing requirements.

How Offset Accounts Work in an SMSF Structure

A linked offset account reduces interest charges by offsetting the cash balance against the outstanding loan amount. For SMSF trustees, this means rental income, member contributions, and any surplus cash can sit in the offset account and reduce the interest payable on the loan without triggering early repayment restrictions or losing access to those funds.

Consider a trustee holding a $400,000 variable rate loan for a commercial property leased to a tenant. Rental income of $2,500 per month flows into the SMSF bank account. If the trustee redirects that income into a linked offset account, the interest calculation applies to $400,000 minus the offset balance. Over a year, an average offset balance of $25,000 reduces interest charges by the full variable rate applied to that $25,000. The cash remains accessible for property maintenance, insurance, or other SMSF expenses.

Not all lenders offer offset accounts on SMSF loans. The loan structure required for superannuation compliance, known as a limited recourse borrowing arrangement, narrows the pool of lenders willing to provide full offset functionality. Some lenders offer partial offset or redraw only. Knowing which lenders support full offset before lodging an application avoids delays.

Redraw Facilities and Why They Differ from Offset

A redraw facility allows the trustee to withdraw any additional repayments made above the minimum required amount. This differs from an offset account in both tax treatment and accessibility.

With redraw, extra funds are paid into the loan itself, reducing the principal balance. To access those funds, the trustee must apply to redraw, and the lender may impose limits on the amount, frequency, or processing time. Some lenders charge a fee for each redraw transaction. For SMSF trustees managing quarterly contributions or irregular rental income, redraw can introduce friction that offset accounts avoid.

The tax treatment also differs. Interest on an investment loan is generally deductible to the extent the borrowed funds are used to purchase an income-producing asset. If a trustee redraws funds and uses them for a purpose unrelated to the original property purchase, the deductibility of interest on that redrawn portion may be affected. Offset accounts sidestep this entirely because the funds never leave the SMSF bank account and are not treated as part of the loan principal.

Repayment Flexibility and Interest-Only Periods

Many SMSF trustees use interest-only repayments during the accumulation phase to preserve cash flow and direct funds toward additional contributions or other investments. Variable rate loans typically allow interest-only periods of up to five years, with the option to extend subject to lender approval and ongoing serviceability.

Interest-only does not build equity through principal reduction, but it allows the trustee to manage liquidity. In a scenario where a trustee holds a $350,000 loan on a residential investment property and receives $1,800 per month in rent, an interest-only repayment of approximately $1,600 per month at current variable rates leaves surplus cash each month. That surplus can be directed into the offset account, reducing the interest payable without committing to higher principal and interest repayments.

Switching from interest-only to principal and interest repayments is typically allowed on variable rate loans without penalty. Fixed rate loans, by contrast, often lock the repayment type for the fixed period. Trustees approaching pension phase may prefer the option to switch repayment structures as income needs change.

Portability and How It Applies to SMSF Property

A portable loan allows the trustee to transfer the loan to a different property without refinancing. This feature is relevant when the SMSF sells one property and purchases another, or when the trustee wants to substitute the security without triggering discharge and application fees.

Portability is less common on SMSF loans than on owner-occupied lending, and not all lenders extend this feature to limited recourse borrowing arrangements. Where it is available, the lender will reassess serviceability and the loan to value ratio of the new property. If the new property is of comparable value and the SMSF continues to meet serviceability requirements, the existing loan can be transferred. This avoids the cost and time involved in discharging the old loan and applying for a new one.

Trustees consolidating multiple properties or restructuring their SMSF portfolio should confirm portability terms before committing to a lender. The feature is rarely advertised and often requires direct confirmation during the application process.

Rate Discounts and How to Retain Them

Variable rate loans for SMSF property often carry a higher interest rate than equivalent owner-occupied loans, but discounts off the lender's standard variable rate are available based on loan amount, loan to value ratio, and the trustee's financial position.

A trustee borrowing $500,000 with a loan to value ratio of 70% may receive a larger discount than a trustee borrowing $300,000 at 80% LVR. The discount is typically applied at settlement and reviewed periodically by the lender. If the trustee makes additional repayments and the LVR drops below a threshold such as 70%, some lenders will increase the discount without prompting. Others require the trustee to request a rate review.

In our experience, trustees who refinance or request a rate review every two to three years maintain lower rates than those who remain with the original lender without review. Loyalty is not rewarded in variable rate pricing. New customers typically receive larger discounts than existing customers, and lenders adjust their appetite for SMSF lending based on market conditions and regulatory settings.

Splitting Between Variable and Fixed Rates

Some trustees split the loan between a variable portion with offset and a fixed portion for rate certainty. A split loan allows the trustee to lock in part of the debt while retaining flexibility on the remainder.

As an example, a trustee with a $600,000 loan might fix $300,000 for three years and leave $300,000 on a variable rate with offset. Rental income and contributions flow into the offset account, reducing interest on the variable portion. The fixed portion provides certainty on half the repayment obligation, which can be useful for trustees in pension phase who rely on predictable income.

The fixed portion typically does not allow offset, extra repayments, or early repayment without break costs. The variable portion retains full flexibility. Splitting requires the trustee to assess how much cash flow will be available for offset and how much rate certainty is worth over the fixed period. There is no standard formula. It depends on the SMSF's income, contribution patterns, and the trustee's risk tolerance.

Applying for a Variable Rate SMSF Loan

The application process requires the trust deed, SMSF financials, member statements, and evidence of rental income or serviceability. Lenders assess the fund's ability to meet repayments from rental income and contributions, not the trustee's personal income.

Some lenders will consider personal guarantees, but the loan itself must be limited recourse, meaning the lender's claim in the event of default is restricted to the property held in the bare trust. The trustee's other SMSF assets are protected.

Pre-approval is available and follows the same process as owner-occupied lending, with the lender confirming loan amount, rate, and features before the trustee identifies a property. This allows the trustee to negotiate on price with certainty around funding.
