Why Traditional Construction Mortgages Are Illegal Under SMSF Borrowing Laws
In standard residential investing, buying vacant land and hiring a builder to construct a house with progress drawdowns (slab, frame, lockup, fix, completion) is a common strategy.
Under Section 67A of the SIS Act, progress-draw construction loans are strictly prohibited when using an SMSF loan. Why? Because the law states that borrowed funds can only acquire a 'Single Acquirable Asset' that exists at the time the loan is entered into.
If your fund takes out a mortgage on vacant land and draws down loan funds to build a house, the asset is considered to have changed from land into a house using borrowed money—a severe violation of super law.
However, you CAN purchase brand-new properties using Single Turnkey Contracts or Off-The-Plan single-part contracts. Here is how compliant developers structure new builds for SMSF buyers. You can verify your borrowing capacity via the National Loan Matcher.
How It Works (Takes 2 Minutes)
1. Why 80% of "Bank Pre-Approvals" Fail Under the Auction Hammer
Most Australian property buyers believe that an email stating "You're Pre-Approved for $1,200,000" means the bank has guaranteed their funds. In the retail banking industry, this is known as an Automated Approval in Principle (AIP).
An algorithm verified that your self-declared income matches basic credit scorecard matrices. No human credit assessor has reviewed your payslips, verified your HECS/HELP debt, or inspected the property's zoning overlay.

| Development Strategy | Borrowing Permitted under LRBA? | How Build is Funded | ATO Legal Compliance |
|---|---|---|---|
| Traditional House & Land (Split Contract) | ❌ Strictly Illegal | Bank progress drawdowns | Breach of SIS Act s 67A |
| Single Turnkey Completed Contract | ✅ 100% Permitted | Builder funds build; SMSF settles 100% on completion | Fully Compliant |
| Off-The-Plan Strata Apartment | ✅ 100% Permitted | 10% deposit in trust; 90% loan drawn at settlement | Fully Compliant |
| 100% Cash Build (Zero Borrowing) | ✅ 100% Permitted | Fund pays 100% cash with no mortgage | Fully Compliant |
1. The Single Turnkey Contract Solution
To acquire a brand-new freestanding home or townhouse inside an SMSF, you must use a 'Single Turnkey Contract'.
Under this arrangement, the builder owns the land and constructs the home using their own commercial working capital. The SMSF pays a standard 10% deposit at exchange. The remaining 90% is funded by your non-bank wholesale SMSF loan only when the property is completely finished and an Occupancy Certificate has been issued.
2. Off-The-Plan Strata Apartments & Townhouses
Buying off-the-plan apartments is fully compliant under Section 67A because the contract of sale is a single legal agreement for a future completed strata lot.
- Deposit Protection: The 10% deposit must be held in a solicitor or real estate agent's statutory trust account (or bank guarantee).
- No Progress Payments: The developer cannot demand interim progress payments from the SMSF during construction.
- Final Settlement: The wholesale non-bank loan settles concurrently with title registration and building completion.
3. What If Your SMSF Has Enough Cash to Build Without a Loan?
If your SMSF has enough accumulated cash to purchase vacant land AND pay for the entire construction in cash (with ZERO mortgage), Section 67A does not apply.
The fund can build, develop, and construct freely, provided the investment strategy complies with general sole purpose and diversification rules.

"We have an auction this Saturday in Paddington with an online pre-approval from CBA for $1.4M. Our conveyancer warned us that Section 66W waives all cooling-off rights. If the hammer falls at $1.38M, what happens if the bank valuer down-values the property on Monday?"
"Under Victoria's Sale of Land Act Section 31, we know auction sales waive the 3-day cooling-off period. Does this also apply if the property passes in and we negotiate a private contract in the auction room 20 minutes later?"
