The short answer: An SMSF that buys property under a limited recourse borrowing arrangement (LRBA) can hold one single acquirable asset, rent it to unrelated tenants, and repair or maintain it with borrowed money — but it cannot use borrowed money to improve the asset, build on it, or top up the loan. Improvements are allowed only from the fund’s own cash, and only if they don’t turn the property into a different asset. And no member or related party can live in it or rent it. These rules come straight from section 67A of the SIS Act and the ATO’s ruling SMSFR 2012/1 — and the line buyers cross most often is the one between renovating and borrowing to develop.
That single distinction is where most of the confusion (and most of the breaches) live, so let me lay the rules out in the order they actually bite.
Key takeaways
- One LRBA, one asset. Borrowed money must acquire a single acquirable asset — generally one property on one title (s67A; SMSFR 2012/1).
- No member or related-party use. An LRBA residential property cannot be lived in or rented by a fund member or a related party (MoneySmart).
- Borrowed money can repair and maintain — not improve. Using borrowed funds to improve the asset breaches the LRBA exception (SMSFR 2012/1, para 15).
- Improvements must come from the fund’s own cash, and must not change the asset into a different asset (SMSFR 2012/1, para 30).
- You cannot borrow to build on land the fund already owns — that converts “vacant land” into “residential premises,” a different asset (SMSFR 2012/1, Examples 8–9).
- You cannot top up or re-draw the loan the way you can outside super — there is no “borrow more against the equity.”
- A granny flat on an existing house is usually fine (from fund cash) because it doesn’t change the property’s residential character (SMSFR 2012/1).
Rule 1 — One LRBA buys one “single acquirable asset”
The foundation rule is the single acquirable asset test in section 67A. Borrowed money must acquire one identifiable object of property. The ATO’s ruling SMSFR 2012/1 spells out the edges: two adjacent blocks of land are generally not a single asset, even if the vendor will only sell them together (Example 1) — they’d need separate LRBAs. But an apartment and a car park on separate titles can be a single asset where State law requires them to be transferred together (Example 4).
Why it matters: this is the rule that quietly governs everything downstream. It is the reason a fund can’t bundle a portfolio under one loan, and the reason the structure has to be right at the moment of acquisition — not patched later.
Rule 2 — No member or related party can use it
A residential property bought under an LRBA cannot be lived in or rented by a fund member or a related party. MoneySmart states it directly: an SMSF property “must not be lived in or rented by a fund member or any of their related parties.” The property has to be a genuine, arm’s-length investment.
This trips up the most well-intentioned plans — the holiday house “we’ll only use occasionally,” the unit for an adult child at “mates’ rates.” Both breach the rule. (Business real property is treated differently and can, in defined circumstances, be leased to a member’s business — but that is a separate route with its own conditions.)
Rule 3 — Borrowed money can repair and maintain, but never improve
Here is the distinction that costs people their LRBA. Money borrowed under the arrangement can be applied to repair or maintain the asset — but cannot be applied to improve it (SMSFR 2012/1, paras 14–15).
The ATO draws the line by fact and degree:
- Repair/maintenance restores the asset’s function without changing its character — replacing a fire-damaged kitchen with modern-equivalent fittings, re-roofing after a storm, repainting to prevent deterioration. Borrowed money is fine for these.
- Improvement significantly betters the asset — extending the house, adding a swimming pool, a pergola, a second storey, or a fully integrated home-automation system. Borrowed money is not allowed for these.
The test is taken against the asset as it was at acquisition. And a “minor or trifling” addition — fitting a leaf-guard while replacing guttering, adding a gate to a new fence — is not treated as an improvement.
Rule 4 — Improvements are fine from the fund’s own cash (with one limit)
You can improve an LRBA property — just not with the borrowing. The fund’s accumulated cash can fund improvements (SMSFR 2012/1, para 30). There is one hard limit: the improvement must not turn the property into a different asset.
That’s the line between an extension and a transformation. From the ruling’s own examples:
- Still the same asset (allowed): an extension adding two bedrooms; a pool; an outdoor entertainment area; a garage; a granny flat in the backyard of an existing house — all keep the property’s residential character.
- A different asset (breaches the LRBA): building a house on what was vacant land; demolishing and rebuilding something not broadly comparable; converting a house into a restaurant with a commercial kitchen.
So a granny flat funded from fund cash is generally fine. Borrowing to build a house on land the fund already owns is not — because it changes “vacant land” into “residential premises,” a fundamentally different asset (SMSFR 2012/1, Examples 8–9).
Rule 5 — You can’t top up or re-draw the loan
Outside super, equity is a tap you re-open: values rise, you borrow against the increase. Inside an LRBA, you cannot. There is no topping up and no re-drawing to fund the next move. Subsequent draw-downs are permitted only to repair or maintain the same asset, and only if the LRBA’s own terms provide for it.
This is the structural fact that most changes how investors should think. The borrowing capacity you set at the start is, in practice, the borrowing capacity you have. Which is exactly why sequence — not just the rate — is the variable that separates a structure that can move again from one that’s stuck.
A worked example, anonymised: a trustee assumed they could “renovate and revalue” their SMSF property the way they had with personal investment properties — borrow against the uplift to fund the next purchase. Inside the LRBA, that lever doesn’t exist. Mapping it before they committed changed the entire acquisition order, and kept a second purchase on the table.
Where this connects to the 2026 changes
These rules are evergreen — they’ve governed SMSF property since 2010. The 2026 reforms sit on top of them by restricting new residential LRBA borrowing. So the picture now is: the long-standing rules above still define what an LRBA property can do, while the new measure narrows when a fund can take on new residential borrowing at all. Understanding both layers is what separates a compliant structure from an expensive assumption.
Frequently asked questions
Can I renovate a property my SMSF bought under an LRBA?
Yes — but mind the source of the money. Borrowed funds can be used to repair or maintain. Improvements (extensions, a pool, a major upgrade) must be funded from the SMSF’s own cash, and must not turn the property into a different asset.
Can my SMSF borrow to build a house on land it already owns?
No. Using borrowed money to build on land the fund already owns changes the asset from “vacant land” to “residential premises” — a different asset — and breaches the LRBA exception (SMSFR 2012/1).
Can I or my family live in an SMSF property?
No. An LRBA residential property cannot be lived in or rented by a fund member or a related party. It must be a genuine arm’s-length investment.
Can I add a granny flat to an SMSF property?
Generally yes, if funded from the fund’s own cash. A granny flat on an existing house usually doesn’t change the property’s residential character, so it isn’t treated as creating a different asset (SMSFR 2012/1).
Can I top up or redraw my SMSF loan like a normal mortgage?
No. There is no topping up or redrawing against equity inside an LRBA. Additional draw-downs are limited to repairs or maintenance provided for in the loan terms.
Can my SMSF buy two properties under one loan?
Generally no. One LRBA acquires a single acquirable asset. Two separate properties would generally need two separate LRBAs.
Before you start the work
Most LRBA breaches aren’t reckless. They’re a renovation, a top-up, or a build that crossed a line the trustee never knew was there. By the time it shows up in the audit, the borrowing is already offside.
If you’re planning anything on an SMSF property — improvements, a second dwelling, drawing on equity — the cheapest hour you’ll spend is pressure-testing the plan against these rules before you commit, not after. You leave knowing what’s safe from fund cash, what needs different funding, and what would put the arrangement at risk.
