The Pros and Cons of SMSF Loans on a Single Income

Buying property through your super on one income is possible, but the fund has to carry the loan, not you. That means a lender will look closely at what goes into your fund each month and what the property earns.

If you are a first home buyer, this matters for a specific reason. An SMSF loan is not a way to buy the home you live in. It is a way to buy an investment property inside your super, and since 10 August 2026 the rules have tightened on what that property can be.

How Does a Lender Assess Serviceability for an SMSF Loan?

For an SMSF loan, a lender checks whether the fund can meet the repayments from its own cash flow. That cash flow mainly comes from the rent the property earns and the contributions going into the fund.

Your personal wages are not the starting point the way they are with a standard home loan. The fund is the borrower, so the lender looks at the fund's income, its expenses and the cash it holds. Each lender has its own policy on how much of the rent and contributions it will count, so it pays to compare SMSF lenders before you apply. A broker can do that comparison for you.

Why Do Contributions Matter on a Single Income?

Contributions matter because they are often the fund's most reliable source of cash apart from rent. On one income, the contributions your employer makes and any you add yourself set a limit on how much loan the fund can carry.

There are caps on how much you can put in. For the current financial year, the concessional contributions cap is $32,500 and the non-concessional cap is $130,000. Going over a cap can bring extra tax, so check your position with your accountant before you plan around large top-ups.

The trade-off is that the money you contribute is generally locked away until you meet a condition of release, such as retirement. There are limited exceptions, such as the First Home Super Saver Scheme for eligible voluntary contributions, but super is not a source of emergency cash.

What Property Can an SMSF Loan Buy Now?

From 10 August 2026, a limited recourse borrowing arrangement entered into to buy real property can only be used for business real property. That generally means land and buildings used wholly and exclusively in one or more businesses.

The ATO states that these loans are not banned. An SMSF can still hold other residential property if it meets the other rules, but it cannot borrow to buy it under this type of arrangement. Loans entered into before that date are not affected, including when they are refinanced later. If you are weighing up a commercial property loan inside super, the property must also stay business real property for the life of the loan. If it stops being used that way, the fund can breach the law against borrowing.

Example: One Income, One Commercial Property Inside Super

Here is an illustrative scenario. Consider a buyer on a single salary whose SMSF has a loan of $400,000 over 25 years. We will use an illustrative rate of 6.75% p.a., which is not a current offer. Repayments would be about $2,764 a month on a principal and interest basis.

Say the commercial premises are leased to a business tenant for $2,000 a month. Say contributions into the fund add about $1,500 a month. Together that is $3,500 a month, which leaves roughly $736 a month after the repayment. That buffer has to cover things like fund administration, insurance, rates and any period without a tenant.

A lender may count only part of the rent or contributions, so the buffer could look smaller on paper. In a scenario like this, the buyer could ask the broker to model a lower loan amount or a larger deposit from the fund's existing balance. With a loan of $350,000 at the same illustrative rate, the repayment falls to about $2,418 a month. That leaves a wider gap between income and repayments, and the lender sees a fund with more room to handle a vacancy.

The cost of the smaller loan is that more of the fund's cash goes into the deposit. That leaves less in the fund for other investments.

The Pros and Cons of Borrowing Through Your Super

The main advantage is that the property sits inside a fund taxed at a concessional rate. A complying SMSF pays 15% on assessable income, and a one-third CGT discount can apply if the asset is held for at least 12 months, which gives an effective rate of 10% on the discounted gain. These are general rules, not a certain result, so speak to your accountant about your own fund.

The disadvantages are real, and on a single income they weigh more heavily:

• The loan is limited recourse, so the lender's claim is generally limited to the property itself. Lenders often respond with a larger deposit requirement or a higher interest rate than a standard loan.
• Borrowed money cannot be used to improve the property. It can cover maintenance and repairs, but not capital improvements.
• One property can represent a large share of a small fund, which concentrates your risk.
• Rent depends on a tenant. If the premises sit empty, your contributions alone have to cover repayments.
• The fund needs a holding trust, and the trustees must keep proper documents, including for an arm's length arrangement if a related party is involved.

Should a First Home Buyer Use Super for Property?

If your goal is a home to live in, super is the wrong tool. If you are still saving for that first home, you may want to look at first home buyer options and use the borrowing capacity calculator to see what a loan outside super could look like.

Super property suits people who already have a meaningful fund balance, steady contributions and a long time before retirement. If you already hold an SMSF loan from before the rule change, SMSF loan refinancing is a separate conversation, and the new rule does not apply to it.

The ATO has also opened consultation on draft updates to its rulings on borrowing and business real property. They are not final, so the detail may change before you sign anything.
