You have found a property you love. It is scheduled for auction in three weeks. The agent calls and says the vendor will consider offers prior to auction - but under auction conditions. Before you sign anything, you need to understand exactly what that means and what you are giving up.

A pre-auction offer is exactly what it sounds like - a formal offer to purchase a property before its scheduled auction date. The agent is legally required to present every genuine offer to the vendor for consideration, regardless of whether the property is headed to auction or not.
In South Australia, the real estate agent has 48 hours to present a written offer to the vendor, unless you as the buyer set a shorter deadline. The vendor can then accept, reject, or counter your offer at their discretion. There is no obligation on the vendor to accept any pre-auction offer, no matter how strong.
The critical question is not whether you can make an offer before auction. You can. The question is what terms that offer will be accepted under - and this is where "auction conditions" changes everything.
When a vendor agrees to sell before auction but insists on auction conditions, they are requiring the same terms they would receive if the property sold at auction. In practice, this means the contract is unconditional. Specifically:
The vendor's logic is straightforward. They have chosen to sell at auction precisely because they want the certainty of an unconditional sale. If they are going to give up the competitive tension of auction day and accept a private offer, they want at least the same level of commitment from the buyer. They are not going to accept conditions they would not have to accept on auction day.
Under Section 5 of the Land and Business (Sale and Conveyancing) Act 1994, buyers in South Australia are entitled to a cooling off period of two clear business days after the Form 1 (vendor's statement) is served. This period does not include the day the Form 1 is served, weekends, or public holidays. During this window, you can cancel the contract by serving written notice on the vendor or agent. No reason needs to be given.
However, the Act provides specific exceptions where cooling off does not apply. The most relevant is sales at auction - if you bid at auction and purchase the property on auction day, there is no cooling off period. The sale is immediately binding.
For pre-auction sales, the cooling off period technically still exists because the property has not actually been sold at auction. This is where the Form R3 comes in.
If you are purchasing under auction conditions before the actual auction date, the vendor will require you to waive your cooling off rights. In South Australia, this is done through a Form R3 - a Waiver of Cooling Off Rights certificate.
The process is designed to protect you, even as you give up a protection. To sign a Form R3, you must first obtain independent legal advice from a solicitor or conveyancer. Your legal practitioner must explain the consequences of waiving your cooling off rights, confirm you understand what you are giving up, and then certify the Form R3 accordingly. You will sign the waiver in the presence of your legal practitioner.
This is not just a box-ticking exercise. Your solicitor should be walking you through the contract, the Form 1 disclosures, and making sure you genuinely understand that once you sign, you are committed. If your finance falls through, if the building inspection reveals problems you did not know about, or if you simply change your mind - you cannot walk away without facing serious financial consequences.
The concept of waiving cooling off for pre-auction purchases exists across Australia, though the mechanisms differ by state. In New South Wales, the equivalent is the Section 66W certificate under the Conveyancing Act 1919 - a solicitor's certificate that waives the standard five business day cooling off period. In Victoria, cooling off does not apply to any purchase made within three business days before or after a scheduled auction, even if the sale occurs privately.
South Australia's two business day cooling off period is already the shortest in the country. Queensland offers five business days, and NSW also provides five. This makes the SA cooling off period a relatively small window to begin with, but its removal still has significant practical consequences - particularly around finance and inspections.
Buying under auction conditions carries genuine risk, and it is important to go in with your eyes open. Here are the main ones:
Without a subject to finance clause, you are personally liable for the purchase price even if your lender declines the loan. Pre-approval is not a guarantee of formal approval. Lenders can withdraw pre-approval if your circumstances change, if the property does not meet their criteria, or if their credit policies tighten between pre-approval and formal application. If your loan is declined after you have signed an unconditional contract, you could lose your deposit and face a damages claim from the vendor.
Without a building and pest clause, you accept the property in its current condition. Structural defects, termite damage, asbestos, faulty plumbing, or electrical issues discovered after signing are your problem. There is no recourse unless the vendor has failed to disclose something they were legally required to disclose in the Form 1.
Your lender will order a property valuation as part of the formal approval process. If the valuation comes in lower than your purchase price, you may need to cover the shortfall from your own funds or risk the loan being declined entirely. Without a finance condition, there is no way to exit the contract if this happens.
The pressure to move quickly on a pre-auction offer can lead to rushed decisions. The fear of losing the property at auction can push buyers to commit before they are truly ready. This is not a decision that should be made under time pressure without proper preparation.
If you are seriously considering a pre-auction purchase under auction conditions, here is how to put yourself in the strongest possible position:
A standard pre-approval is a starting point, but for an unconditional purchase you want to go further. Talk to your broker about getting your application as close to formal approval as possible before you make the offer. This means having all your documents submitted, your income verified, and your borrowing capacity confirmed. The closer you are to full approval, the lower your finance risk.
Some lenders will issue a conditional approval that is only subject to a satisfactory valuation of the specific property. This is much stronger than a standard pre-approval and significantly reduces your risk in an unconditional purchase.
This is non-negotiable. If you are buying without a building clause, you need to know what you are buying before you commit. Arrange a building and pest inspection before submitting your offer. The cost is typically between $400 and $700, which is a small price compared to the cost of discovering major defects after you have signed an unconditional contract.
If the inspection reveals issues, you can factor the cost of repairs into your offer price, or decide not to proceed. This is exactly the same approach you would take if you were planning to bid at the auction itself.
Before you commit, your solicitor or conveyancer should review the contract of sale and the Form 1 vendor's statement thoroughly. The Form 1 contains important disclosures about the property - title details, encumbrances, zoning, planning notifications, and other matters that could affect your ownership. Your conveyancer should flag anything unusual before you sign.
This is also when your legal practitioner will advise you on the Form R3 cooling off waiver and make sure you understand the implications.
One of the advantages of a pre-auction offer is that you avoid the emotional heat of auction day bidding. Use that advantage. Set your maximum price based on comparable sales, your borrowing capacity, and your own financial situation. Do not let the urgency of a pre-auction negotiation push you beyond what the numbers support.
Under auction conditions, the deposit (usually 10% of the purchase price) is typically required immediately. Make sure you have these funds accessible and cleared. A delay in paying the deposit can give the vendor grounds to walk away from the deal.
Vendors choose to accept pre-auction offers for several reasons. The most common is certainty. Auction day is not guaranteed - the property may not reach the reserve, there may be fewer bidders than expected, or market conditions may shift in the weeks before auction. A strong unconditional offer before auction removes that uncertainty.
Other factors include the vendor's personal timeline (they may need to settle quickly), the cost of continuing the marketing campaign, or simply receiving an offer above their expectations. An agent will generally recommend that a vendor consider a pre-auction offer seriously if it is strong enough to justify cancelling the auction.
Equally, many vendors will reject pre-auction offers because they believe the competitive environment of auction day will deliver a better result. You should be prepared for a rejection and have a plan for auction day as well.
There is nothing stopping you from submitting a conditional offer - subject to finance, subject to building inspection, or with a longer settlement period. The agent must present it to the vendor. However, the practical reality is that most vendors listing at auction will not accept conditional offers. The entire point of choosing an auction campaign is to achieve an unconditional sale, and a conditional offer undermines that objective.
There are exceptions. If your offer price is significantly above expectations, or if the property has been on the market for a while with limited interest, a vendor might accept conditions. But in a competitive Adelaide market, this is the exception rather than the rule.
Relying on pre-approval as if it were formal approval. Pre-approval is an indication, not a commitment from the lender. It can be withdrawn, it has an expiry date, and it is subject to the lender being satisfied with the specific property. Treat pre-approval as a starting point, not a safety net.
Skipping the building inspection to save time. In a fast-moving situation, it can be tempting to skip the inspection and hope for the best. This is a false economy. A few hundred dollars and a few days of lead time is all it takes to protect yourself from a potentially very expensive mistake.
Not understanding the deposit implications. If you sign an unconditional contract and then cannot settle, you will lose your deposit. On a $700,000 property, that is $70,000. The vendor can also pursue you for further damages if they sell the property for less than your contracted price. This is real money at stake.
Not getting independent legal advice before signing the Form R3. The requirement to obtain legal advice before waiving cooling off rights exists for a reason. Use the opportunity to ask questions, understand the contract, and make sure you are comfortable with what you are signing.
Assuming the agent is looking out for you. The selling agent works for the vendor, not the buyer. They are required to present your offer and deal with you honestly, but their primary obligation is to achieve the best result for the vendor. Get your own advice from your broker, your conveyancer, and if needed, a buyer's agent.
If you are considering buying under auction conditions, this is exactly the kind of situation where a broker adds real value. We can assess how close your pre-approval is to formal approval, identify any risks that could cause your application to be declined, and work with the lender to get as much certainty as possible before you commit.
We can also help you understand your true borrowing position, factor in the deposit requirements, and make sure you are not stretching beyond what is realistic. An unconditional purchase is not the time to be at the very edge of your borrowing capacity with no buffer.
The goal is to make sure that when you sign that unconditional contract, you are doing so from a position of genuine confidence - not hope.
Buying before auction under auction conditions can be a smart strategy. You avoid the unpredictability of auction day, you can negotiate privately without the pressure of competing bidders in the room, and if the vendor is motivated, you may secure the property at a price that reflects value rather than auction-day emotion.
But it requires preparation. You need your finance confirmed as far as possible, your inspections completed, your contract reviewed by a solicitor, and your deposit ready. You are trading the protections that come with a standard private treaty sale - cooling off, finance conditions, inspection clauses - for speed and certainty. That trade-off only makes sense if you have done the work upfront.

You can try, but vendors listing at auction are typically seeking unconditional certainty. Most will only accept a pre-auction offer if it comes under auction conditions - meaning unconditional, with no cooling off period, no subject to finance, and a 10% deposit. Some vendors may entertain a conditional offer if the price is compelling enough, but it is uncommon.
Form R3 is the Waiver of Cooling Off Rights certificate under the Land and Business (Sale and Conveyancing) Act 1994. To waive your cooling off rights, you must obtain independent legal advice from a solicitor who will then certify that you understand the implications of giving up your right to cancel the contract during the standard two business day cooling off period.
It depends on the contract terms. If you purchase under auction conditions (which is what most vendors will require for a pre-auction sale), you will be asked to waive your cooling off rights via a Form R3 signed by your solicitor. If you negotiate a standard private treaty contract with conditions, the normal two business day cooling off period applies. The key distinction is the contract terms, not the timing.
Under auction conditions, a 10% deposit is standard and typically payable immediately upon the vendor signing the contract. In some cases, you may be able to negotiate this down, but vendors accepting pre-auction offers under auction conditions generally expect the same deposit they would receive at auction.
Yes, absolutely. Because the contract will be unconditional, you will not have the opportunity to conduct inspections after signing. Arrange a building and pest inspection before you submit your offer. The cost - typically $400 to $700 - is small compared to the risk of purchasing a property with undisclosed structural issues.
