SMSF loans: how borrowing inside super actually works

Borrowing to buy property inside a self-managed super fund is legal, established, and more tightly rule-bound than any other kind of lending covered on this site. The structure that makes it possible — the limited recourse borrowing arrangement, or LRBA — was deliberately designed with guard rails, and stepping outside them can have serious consequences for the fund's complying status. This article explains how the structure works and what it demands of a fund, in general terms. It is not financial advice, and it is not a substitute for it: whether an SMSF, or borrowing inside one, is right for you is a question only a licensed financial adviser can properly answer against your circumstances.

Important update (as at July 2026): under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026, SMSFs generally cannot enter new LRBAs to acquire residential property from 10 August 2026. Existing residential LRBAs are unaffected, outright cash purchases remain subject to the usual rules, and LRBAs over commercial property are untouched. The rest of this guide applies to commercial borrowing and to arrangements already in place — see [what the 2026 LRBA changes mean for trustees](/articles/smsf-loans/smsf-property-loans-after-2026-lrba-changes) for the detail, and confirm the current rules with the [ATO](https://www.ato.gov.au) and your licensed adviser.

What an LRBA is

Superannuation law generally prohibits SMSFs from borrowing. The LRBA is the specific, legislated exception, and its architecture reflects the caution behind it:

• The SMSF trustee takes out the loan and uses it, together with the fund's own money, to buy a single acquirable asset — typically a commercial property (or, for arrangements entered before 10 August 2026, a residential one)
• The asset is held on a separate trust, commonly called a bare trust (or holding/custodian trust), with its own trustee, until the loan is repaid. The SMSF holds the beneficial interest and receives the rent and, eventually, the title
• The lender's recourse is limited to that asset. If the loan fails, the lender can take the property held in the bare trust, but cannot reach the fund's other assets — its shares, cash and other investments are quarantined

That limited recourse is the point of the whole design: it protects members' retirement savings from a single failed investment. It also explains why lenders treat SMSF loans conservatively — their security is one asset, full stop — and why in practice most lenders also require personal guarantees from members, which is one of the details that deserves professional advice before anyone signs.

What the fund can and cannot do

The rules around LRBA property are strict, specific, and enforced. In general terms:

• The fund cannot buy residential property from a member or a related party, and members and their relatives cannot live in or rent the fund's residential property — at any price. Residential LRBA property must be genuinely at arm's length
• Business real property is the notable exception. A commercial property used wholly in a business — such as your own premises — can generally be acquired from and leased back to a related party, provided everything happens on strict arm's-length terms: market rent, a proper lease, rent actually paid on time. This is why SMSF borrowing is most often discussed by business owners buying their premises
• Borrowed money cannot fund improvements. The fund can maintain and repair the property using borrowed funds, but improvements that change the character of the asset generally cannot be made with borrowings while the LRBA is in place — a knock-down rebuild or a substantial renovation program is off the table
• One arrangement, one acquirable asset. You cannot buy a development site under one LRBA and subdivide it, and property development activity inside an LRBA is heavily constrained
• Every dollar must serve the sole purpose of providing retirement benefits. The sole purpose test sits over all of it, and arrangements that deliver present-day benefits to members risk the fund's complying status

The distinction between a repair and an improvement, or between arm's length and not, is exactly the kind of line that looks obvious until it isn't. When in doubt, that is a question for your accountant or SMSF specialist before the money moves — not after.

What lenders require

SMSF lending is a specialist market. Several major banks have exited it, and the lenders that remain apply settings that are conservative by design. In general terms, expect:

• Lower maximum LVRs than standard lending — SMSF loans typically require substantially larger deposits than a comparable personal purchase, with commercial security usually capped lower than residential
• Liquidity requirements. Many lenders require the fund to retain a minimum level of liquid assets — often expressed as a percentage of the fund's balance — after settlement, so the fund is not left holding one property and an empty bank account
• Serviceability assessed inside the fund. Repayments must be covered by the fund's own income: rent from the property plus contributions and other fund earnings, assessed with buffers. Contribution caps limit how much can be tipped in, so a thin fund cannot simply be topped up at will
• Structural paperwork. The trust deed must permit borrowing, the bare trust must be established correctly and in the right sequence relative to the contract, and most lenders require the fund to have — or obtain — professional advice as a condition of the loan

Getting the sequencing wrong — signing the contract in the wrong name, establishing the bare trust incorrectly — can create duty and compliance problems that are expensive to unwind. This is a transaction where the lawyers and accountants earn their fees before settlement, not after.

Liquidity: the requirement that protects you

The liquidity rules deserve their own moment, because they are not red tape — they are the difference between a resilient fund and a fragile one. A fund that puts nearly everything into one property plus a loan is exposed on several fronts at once: a vacancy stops the rent while repayments continue; property expenses arrive unevenly; and when members reach retirement, the fund must be able to pay benefits — hard to do when the money is in bricks. A sensible liquidity buffer, and honest modelling of vacancy and rate movements against the fund's contribution flow, is what turns an SMSF property strategy from a hope into a plan. Your financial adviser can model this properly; it should be modelled before anything is signed.

Why specialist advice is required, not recommended

We use the word deliberately. An SMSF borrowing decision touches superannuation law, trust law, tax, duty, retirement strategy and insurance inside super, and errors can affect the fund's complying status — which is a materially worse outcome than an ordinary bad investment. Before any SMSF loan proceeds, you should have:

• A licensed financial adviser confirming that the strategy suits your retirement position, your fund's scale and your risk capacity — including whether an SMSF is appropriate for you at all
• An accountant or SMSF specialist handling the structure, the trust deeds, the compliance settings and the ongoing administration and audit
• A solicitor managing the bare trust documentation and the contract in the correct names and sequence

As a broker, our role sits alongside those advisers — arranging finance within a structure the professionals have signed off — never in place of them. Anyone who suggests skipping the advice to save costs is telling you something important about their own advice. The ATO publishes guidance on SMSF borrowing and trustee obligations; the general information on this page is no substitute for it or for personal advice, and rules change, so confirm the current position (as at July 2026) with your advisers.

Where borrowing inside super genuinely fits

Used well, an LRBA is a considered piece of a retirement strategy — most commonly an established business owner acquiring their business premises through their fund at arm's-length rent, inside a fund with real scale, genuine liquidity after settlement, and advisers who have modelled the whole picture, as discussed in our [commercial property guide](/articles/commercial-finance/commercial-property-loans). Used badly, it is a thin fund concentrated in one asset it cannot afford to hold. The structure is the same in both cases; the advice is the difference.

Talk it through with a broker

If your advisers have recommended an SMSF property strategy — or you are still working out whether the question is worth asking them — we can explain the finance side: which lenders are active, what deposits and liquidity they expect, and how the approval process runs. [Get in touch](/contact) and we will make sure the lending piece fits the plan your advisers build.
