Simple hacks to assess SMSF loan serviceability

Serviceability assessment for Self-Managed Super Fund loans differs fundamentally from personal lending. Lenders assess the fund's capacity to service debt using contributions made to the fund and rental income generated by the property, not the member's personal income.

How Lenders Calculate SMSF Borrowing Capacity

Lenders calculate SMSF borrowing capacity by assessing the fund's available income against the proposed loan repayments. The two income sources considered are member and employer contributions flowing into the fund, and rental income expected from the property being acquired. Contributions must be regular and sustainable. A lender will typically require evidence of contributions over the previous 12 to 24 months and may discount projected contributions if the member is approaching preservation age or retirement. Rental income is assessed using a signed lease or a rental appraisal from a licensed agent, often with a buffer applied to account for vacancy and maintenance costs.

Consider a member aged 48 contributing $32,500 annually in concessional contributions to their fund. The fund has $420,000 in accumulation and intends to purchase a commercial property under a Limited Recourse Borrowing Arrangement with an expected rental yield of $28,000 per year. The lender assesses serviceability by combining the annual contribution of $32,500 with net rental income, typically applying a 20 to 25 percent discount to the gross rent to account for outgoings and vacancy. At a 20 percent discount, net rental income is assessed at $22,400. Combined income is $54,900 annually. The lender then applies a serviceability buffer, often assessing the loan at a rate 2 to 3 percentage points above the actual loan interest rate. If the loan amount is $500,000 and the lender assesses at 8.5 percent, annual interest is approximately $42,500. The fund can service this borrowing.

Contribution History and Sustainability Requirements

Lenders require at least 12 months of verifiable contribution history before assessing serviceability. The concessional contributions cap is $32,500 per annum from 1 July 2026, and most lenders will not assess contributions above this cap as sustainable income unless the member has available carry-forward concessional cap space and provides evidence of the intention and capacity to use it. Where a member is within five years, lenders may reduce the weighting of contributions or decline to rely on them entirely, as the member may move to pension phase and cease contributions. Non-concessional contributions are generally not considered sustainable income for serviceability purposes, as they are discretionary and do not reflect ongoing cashflow.

In our experience, self-employed members often face additional scrutiny. Lenders may require business financials, tax returns, and accountant declarations to verify that the business can sustainably support the level of contributions being made to the SMSF. Where business income is variable or declining, the lender may discount or exclude contributions from the serviceability assessment.

Rental Income Assessment for Commercial and Residential Property

Rental income is assessed differently depending on whether the property is residential or commercial. For residential property held under an LRBA entered into before 10 August 2026, lenders typically apply a shading factor of 20 to 25 percent to gross rent. For commercial property, the treatment depends on the lease structure. A property leased to an arm's length tenant on commercial terms with a lease term of three years or more is generally assessed at a lower shading rate, often 10 to 15 percent, reflecting the greater income security. A property leased to a related party requires the lease to be on arm's length terms at market value, and lenders will often require an independent valuation and rental determination to support serviceability.

Where the property being acquired is vacant, the lender will require a rental appraisal from a licensed agent. Some lenders will not proceed without a signed lease in place at settlement, particularly for higher loan-to-value ratio lending or where contributions alone are insufficient to service the debt.

Loan-to-Value Ratio and Deposit Requirements

Most SMSF lenders operate within a maximum loan LVR of 70 to 80 percent, with 80 percent typically reserved for residential property in metropolitan areas and 70 percent more common for commercial property or regional residential property. A deposit of at least 20 to 30 percent of the purchase price is required, plus settlement costs including stamp duty, legal fees, and loan establishment costs. These costs cannot be funded through the LRBA and must be paid from existing fund assets or contributions made before settlement.

Where the fund's existing balance is insufficient to meet the deposit and costs, members may make additional concessional or non-concessional contributions subject to the relevant caps. The non-concessional contributions cap is $130,000 per annum, with a bring-forward arrangement available for members whose total superannuation balance on 30 June of the previous year was below $1.84 million. Members in Windsor with balances approaching $2.1 million should be aware that the non-concessional cap reduces or becomes nil as the balance increases.

Impact of the 10 August 2026 LRBA Changes on Serviceability

From 10 August 2026, LRBAs entered into to acquire real property are restricted to business real property. Residential property can no longer be acquired under a new LRBA. This does not change how lenders assess serviceability for SMSF loans, but it does narrow the range of properties available. Business real property under section 66 of the SIS Act means land and buildings used wholly and exclusively in one or more businesses. The business does not need to be carried on by the fund. A retail shop, office, warehouse, or industrial unit leased to a tenant operating a business will typically satisfy the definition, provided the property is not used for residential purposes.

Existing residential LRBAs entered into before 10 August 2026 can be maintained and refinanced without restriction. Funds in Windsor holding residential property under an LRBA established before that date can continue to rely on rental income and contributions for serviceability assessment when refinancing to a new lender or reviewing loan terms with their current lender.

Leasing Commercial Property to a Related Party

Business real property leased between the fund and a related party is excluded from the in-house asset rules, but the lease must be made on arm's length terms at market value. A Windsor-based member operating a business from a commercial premises may establish an SMSF, acquire the premises under an LRBA, and lease it back to their business. The rent paid by the business forms part of the income used to service the SMSF loan. Lenders will require independent evidence that the rent is at market value, typically through a valuation or rental determination by a qualified property professional. Where the rent paid by the related party business exceeds market value, the excess may be treated as a return of capital or assessed as non-arm's length income and taxed at 45 percent. Where the rent is below market value, the fund may breach the sole purpose test under section 62 of the SIS Act.

Consider a member who operates a consulting business from a small office in Windsor. The fund acquires the office for $650,000 with a 30 percent deposit and borrows $455,000 under an LRBA. The business pays rent of $32,000 per year, supported by a rental determination. The member also contributes $27,500 annually in concessional contributions. The lender assesses rental income at $27,200 after a 15 percent shading and combines this with contributions to assess total income of $54,700. The loan is serviceable at current variable rates with an appropriate buffer applied.

Tax Treatment of Rental Income and Capital Gains

Rental income received by the fund is taxed at 15 percent in accumulation phase. Expenses directly related to the property, including loan interest, property management fees, repairs, and depreciation, are deductible. Where the fund holds the property to support a retirement-phase income stream, rental income may be exempt from tax under the exempt current pension income rules, provided the fund's assets are fully segregated or the income is attributed to pension assets under the proportionate method.

Capital gains realised on disposal of the property are also taxed at 15 percent in accumulation phase, with a one-third CGT discount available where the property has been held for at least 12 months. The effective tax rate on the discounted gain is 10 percent. Where the property is held to support a pension and the fund's assets are fully segregated at all times during the income year, the capital gain is disregarded. Division 296 tax applies from 1 July 2026 to members whose total superannuation balance exceeds $3 million, with an additional 10 percent tax on balances above $10 million. LRBA amounts are disregarded when calculating the member's total superannuation balance for Division 296 purposes, meaning only the net equity in the property is counted.
