TLDR
3,613 signed detached home contracts are in limbo after the ban on new SMSF borrowing for residential property took effect. Builders expect roughly two-thirds of those contracts to be cancelled, while industry bodies warn the flow-on damage to apartment pipelines and tax revenue will be substantial.
KEY TAKEAWAYS
What the ban covers and who is affected
Self-managed superannuation funds have been able to borrow under limited recourse borrowing arrangements, or LRBAs, to buy investment property since the Superannuation Industry (Supervision) Act 1993 first permitted the practice. The structure limits the lender's claim to the purchased asset, so the rest of the fund's retirement savings stay protected if the deal goes wrong. That mechanism is now closed for residential property.
The Treasury Laws Amendment (Tax Reform No 2) Bill 2026 passed Parliament and prohibits SMSFs from entering new residential LRBAs from 10 August 2026.[2] Transitional rules allow contracts exchanged before that date to proceed to settlement under the old rules, but every new purchase from that point forward must be funded without SMSF borrowing.[2] The practical consequence lands on two distinct parts of the housing market: detached home builders with signed but unstarted contracts, and apartment developers counting on SMSF presales to unlock construction finance.
HIA survey findings: 3,613 contracts, 66.9% cancellation estimate
A Housing Industry Association survey of Australia's largest detached home builders found they currently hold 3,613 signed contracts backed by SMSF limited recourse borrowing arrangements that have not yet commenced construction.[1] Those builders estimate 2,415 of those contracts, equal to 66.9%, are likely to be cancelled now that the ban is in force.[1]
The damage extends beyond contracts already signed. More than 70% of surveyed builders reported a decline in investor enquiries since the Federal Budget first flagged the measure, and almost 90% expect detached housing commencements to fall during 2026 and 2027 as a direct consequence.[1] HIA calculates the combined effect of cancellations and weaker forward sales will reduce detached commencements by between 3.5% and 5%, stripping more than $450 million in GST and stamp duty revenue from state governments.[1]
HIA Chief Economist Tim Reardon said the ban on SMSFs building new homes undermines the governments' objective of building 1.2 million homes and improving housing affordability.[1]
Apartment market exposure
The detached sector's 3,613 contracts represent only part of the story. Consultancy Charter Keck Cramer has estimated around 22,000 off-the-plan apartments may also not proceed, with the risk concentrated in Melbourne, Brisbane and western Sydney. Apartment developers routinely need a minimum volume of presales before a bank will release construction finance, and SMSF investors have become a reliable source of those presales.
UDIA National warned that SMSF investors have become an important component of the presale market, helping projects reach the thresholds required for construction financing, and that removing this mechanism will further undermine housing supply.[3] When SMSF buyers step back, the gap does not automatically fill with other investors, and projects can sit in the pipeline indefinitely without reaching the finance trigger.
Oscar Stanley, President of the Urban Development Institute of Australia, said Australia's housing crisis is a supply problem and that if governments are serious about delivering more homes, they should be removing barriers to investment in new housing, not creating new ones.[3]
The exemption and the settlement timing risk
Buyers who exchanged a valid contract before 10 August 2026 are exempt from the ban and may still settle under the old LRBA rules, even if settlement occurs twelve to twenty-four months after exchange.[2] That exemption sounds straightforward, but the SMSF Association has flagged a practical complication: off-the-plan buyers with pre-August contracts will still need an SMSF residential LRBA product available at the time of settlement, which may be well into 2027 or 2028.
SMSF Association Chief Executive Peter Burgess said that a trustee who signs a valid off-the-plan contract before 10 August 2026 may settle twelve to twenty-four months later and still need an SMSF residential LRBA product at settlement.[2] If lenders withdraw those products in response to the ban, a buyer who is technically exempt on paper may find no product exists to complete the purchase.
The SMSF Association has been pushing for a new-property exclusion that would allow SMSFs to continue borrowing specifically to fund newly built residential dwellings, arguing this preserves the supply incentive without opening the door to speculation in existing housing stock. That position has not yet attracted government support.
Industry response and the housing target arithmetic
The federal government's target of 1.2 million new homes by 2029 was already considered ambitious before the LRBA ban arrived. The HIA survey adds concrete numbers to what had previously been a theoretical concern: real signed contracts, with real buyers, are now expected to dissolve at a two-thirds rate, with each cancellation representing a home that will not be built and a state government that does not collect the associated GST and stamp duty.
HIA puts the aggregate revenue hit to states at more than $450 million, a figure that matters because states bear much of the cost of housing infrastructure.[1] The ban is in place, the 3,613 contracts are at risk, and the SMSF Association's push for a new-property exclusion remains unresolved as of August 2026.
