The Auction Timeline: From Mandate to Sold — What Happens, and When
One of the most common questions I get from sellers in Blouberg Rise, Blouberg Sands, Big Bay, Sunningdale, and West Beach isn't "does auction work" — it's "how long does this actually take, and what's happening in the background each week?" Fair question. Private treaty sales have notoriously unpredictable timelines; one of the auction method's biggest underrated advantages is that it doesn't. Here's the calendar, laid out plainly, from the day you sign the mandate to the day the money settles.
Week 0: Signing the Mandate and Setting Your Numbers
Before the clock starts on the public-facing campaign, there's a foundational step that happens privately between you and your agent: signing the mandate and agreeing on your pricing benchmarks.
This is where you and your Harcourts agent establish your reserve price — the confidential minimum below which the property cannot sell — along with the other figures that guide decision-making throughout the campaign. Harcourts' own seller guidance recommends thinking in terms of your best price (what you'd be very happy to accept) and your ok price (what you'd be satisfied with, based on market feedback, even without feeling like an outright win). Getting these numbers settled now — rather than negotiating them under pressure mid-campaign — is what makes the rest of the timeline run smoothly. ZAWYA
This is also when your agent should walk you through what to expect week by week, so the campaign never feels opaque while it's running.
Weeks 1–2: Preparation
The Harcourts auction campaign is built around a six-week structure: two weeks of preparation followed by four weeks of active marketing. Nothing about this period is wasted time — it's where the foundation for everything that follows gets laid. IOL
During these two weeks, expect:
- Professional photography and, where appropriate, drone or video content (particularly valuable for properties with sea views or proximity to the Big Bay beachfront)
- Copywriting and the property's online listing presence going live in preparation
- Your agent compiling the property information package — disclosures, reports, and documentation that buyers will need, prepared in advance rather than left for buyers to chase down later
- Early, quiet outreach to buyers already known to be active in your specific suburb or property type
By the end of week two, the property hasn't been publicly marketed yet — but the groundwork that determines how well the public campaign performs has already been done.
Weeks 3–6: Active Marketing
This is the visible phase of the campaign — four weeks of sustained marketing pointing toward a single, fixed auction date.
Open houses run on a predictable rhythm. Harcourts' guidance for sellers notes that condensing viewings into a limited, regular schedule — typically twice a week — helps create a clearer perception of demand and keeps the process well managed, rather than buyers wandering through on an ad hoc basis.

You're not left wondering what's happening. A properly run campaign includes weekly communication between you, your agent, and the auctioneer, so you stay informed of market feedback throughout — whether through calls, emails, or direct meetings. This matters because pricing expectations sometimes shift as real buyer feedback comes in, and you should never be hearing about that shift for the first time in week five. Theppra
Offers can — and often do — come in before auction day. It's a common misconception that nothing happens until the auction itself. In reality, you set the bidding parameters together with your agent before the property goes live, and pre-auction offers are common — most sellers receive at least some offers before auction day even arrives. All offers made during the campaign are disclosed to you, and the decision of whether to accept, counter, or continue toward auction day remains entirely yours.
By the end of week six, the campaign has built toward a single, known date — and you've had weekly visibility into exactly how much interest exists.
The Week Before: Bidder Registration and Final Preparation
In the days leading into auction day, the administrative groundwork for the auction itself takes shape.
Bidders must register before they can bid at all. Any party intending to bid must register before the auction begins — the auctioneer will not accept bids from anyone who hasn't registered or doesn't have a visible bidder identifier, with a driver's licence or passport typically sufficient for identification. Registration and agreement to the auction terms must be completed by the buyer personally — an agent cannot register on a buyer's behalf.
A final open house gives last-minute clarity. This is the buyer's final opportunity to inspect the property and resolve any outstanding questions before committing — and it's also a useful moment for you, as the seller, to gauge the room one last time before auction day itself.
Buyers who can't attend in person still have options. Bidders unable to be present typically arrange to bid through a family member, friend, or the agent, provided written authority has been supplied to the auctioneer before the auction begins — or via telephone or online bidding platforms, depending on what the specific auction permits.
Auction Day: Hours, Not Weeks
After six weeks of campaign work, auction day itself typically resolves in a matter of hours.
Bidding begins, and it's best to engage early. It's important to bid on the property from the outset rather than waiting for the auctioneer to declare it "on the market" — a delay tactic that's been promoted in some circles but more often ends in disappointment than success.
The auctioneer may use a vendor bid. This is a detail that catches some first-time buyers off guard, so it's worth explaining clearly: the auctioneer, acting on the seller's behalf, may place one or more bids up to — but never reaching — the reserve price, and any such vendor bid must be disclosed as such. A vendor bid doesn't reveal what the seller will ultimately accept; it's simply a tool to open or move bidding toward a realistic level, particularly common when only a small group of bidders is present.
If reserve is met, it's final, immediately. At the fall of the hammer, the sale is final — if your bid is successful, the property is yours with no further negotiation, and the contract of sale is signed on the spot.
If it doesn't reach reserve, it's "passed in" — not failed. If the property doesn't reach the seller's reserve, it's "passed in," and the highest bidder gains the right to negotiate directly for the property; if they decline, other interested parties are typically given the opportunity to submit offers. If you're an under-bidder, it's worth staying until you know for certain whether the property has sold, since auction conditions on a successfully negotiated price typically apply up until midnight on auction day itself.
After the Hammer: Deposit, Contract, and Settlement
For a successful buyer, the post-auction sequence moves fast and is fully binding.
The deposit is due immediately. A signed sales agreement and deposit — commonly around 10% of the purchase price — are required on the spot, with no cooling-off period attached to an auction purchase.
Settlement follows on a fixed schedule. The settlement date is set out in the contract of sale as a defined number of days from the contract date — commonly around 30 days, though this can vary by agreement. From here, the process moves into standard conveyancing: transfer attorneys, bond registration (if applicable), and the usual administrative steps to formal registration of the property in the buyer's name.
For you as the seller, this is where the timeline advantage of the auction method becomes most concrete: you know the settlement date weeks in advance, rather than discovering it only once a private treaty offer has finally been negotiated, accepted, and made unconditional.
Why the Timeline Itself Is the Advantage
Step back from the individual weeks and the real benefit becomes clear: at every stage, you know what's happening and roughly when the next thing happens. Compare that to private treaty selling, where a property can sit on the market for weeks or months with no fixed point at which a decision gets made, and where each new offer resets the negotiation clock. The auction timeline compresses uncertainty into six structured weeks plus a known settlement period — which, for sellers juggling a subsequent purchase, a relocation, or simply wanting clarity, is often as valuable as the price outcome itself.
