I've Bid at 200+ Auctions. Here's the Playbook They Don't Want You to Know.

Let me set the scene.

Saturday afternoon. Online auction — the kind that became normal after COVID turned live auctions into Zoom calls. My client is sitting at his kitchen table, laptop open, phone on speaker with me on the other end. He's a first-time investor. Hasn't done this before. And the property he wants — a 730-square-metre block with subdivision potential — has just hit $1.2 million.

The auctioneer is doing what auctioneers do: creating urgency, compressing time, making everyone feel like they need to act NOW. Countdown timer. Ten seconds. "Do I have any further bids? This property is on the market."

My client panics. "The one next door sold for $1.15 million! Is this too much? Should I bid $1,205,000?"

I cut him off. "No. That comp is irrelevant. That property had no development potential. Zero value-add. Its land-to-value ratio was 50%. Ours is 70%. Different asset entirely. Don't bid $1,205. Bid $1,220."

"That's $20K more than —"

"Do it. Now. Trust me."

He entered $1,220,000. Hit submit.

Silence.

"Sold."

He collapsed back in his chair. I pulled over to the side of the road and let out a breath I didn't realise I'd been holding. Another one landed.

That property revalued at $1,340,000 eight months later. The $20,000 "overpay" that terrified him turned out to be the best money he ever spent.

Why most auction bidders lose before they start

Here's what separates amateurs from professionals at auction: amateurs bid reactively. Professionals bid strategically.

An amateur walks into an auction with a maximum price and a vague plan to "see how it goes." They bid in $5,000 increments, trying to save money. They hesitate. They look around to read the room. They adjust their maximum based on who else is bidding.

Every single one of those behaviours is wrong.

The auctioneer's entire job is to extract the maximum price from the room. They're trained to read hesitation, exploit it, and use the competitive energy of multiple bidders to push prices beyond what any individual buyer planned to pay 1.

When you bid in small increments, you signal that you're close to your limit. The auctioneer sees that. Other bidders see that. You become the person everyone is trying to outlast by one more bid.

When you hesitate, you create a void that the auctioneer fills with pressure. "Take your time, but the hammer is about to fall." That line is designed to make you panic-bid.

I've been on the other side of this — I've been the person in the auctioneer's ear, having a quiet word during vendor's bids. I know exactly how the psychology works. And I use it against the process, not with it.

The nuclear bid strategy

I call it the nuclear bid because it's designed to end the auction in one move.

Here's how it works. Before the auction, I've already done three things:

1. Established fair value. Not market value — fair value. Based on recent comparable sales within 500 metres, adjusted for block size, dwelling condition, and development potential. I know exactly what this property is worth to us as an investment 2.

2. Identified the value-add. Does it have subdivision potential? Granny flat potential? Renovation upside? This is the premium above market value that we can justify because we'll create additional value that other buyers can't or won't.

3. Set the walkaway price. This is the hard ceiling. Not a "soft" ceiling that I might flex in the heat of the moment. A mathematical ceiling based on the investment returning our minimum yield target.

With those three numbers locked in, I don't bid incrementally. I wait. I let other bidders exhaust themselves in $5,000 and $10,000 increments. I watch the room thin out until it's down to two or three parties.

Then I drop the nuclear bid.

Instead of bidding $5,000 above the current price, I bid $15,000 or $20,000 above. A jump so large that it demoralises the other bidders and signals that I've got significantly more room. In reality, I might be $25,000 from my walkaway price. But the other bidders don't know that. What they see is someone who just leapt $20,000 in a single bid — which implies I've got another $100,000 behind it.

Most of the time, the auction ends right there. The competitors' resolve crumbles. Their body language deflates. They shake their heads. Done.

I've used this strategy at over 200 auctions. Win rate: 78%. Average saving versus vendor expectation: $35,000 3.

When the nuclear bid doesn't work

Sometimes it doesn't. Sometimes the other bidder is a developer who's done the same maths and has a higher ceiling. Sometimes it's an emotional buyer — a family who's fallen in love with the house and will pay whatever it takes.

You need to recognise these situations fast.

Developers bid differently. They don't hesitate. They don't look around the room. They bid in round numbers, instantly, without flinching. When I see that pattern, I know I'm up against someone who has a spreadsheet, not a dream. The auction becomes a pure numbers game.

Emotional buyers are the opposite. They bid in odd amounts — $1,213,000 instead of $1,215,000 — because they're trying to save every dollar. They whisper to their partner between bids. They visibly agonise.

Against a developer, I respect the maths. If their ceiling is above mine, I walk away. No property is worth overpaying for, regardless of how good it looks on paper.

Against an emotional buyer, the nuclear bid is devastatingly effective. Because emotional buyers are already at the edge of their financial comfort zone. A $20,000 jump pushes them past it.

The hardest thing in auction strategy isn't bidding. It's walking away. I've walked away from properties that I wanted badly — properties where the numbers were almost right but not quite. My rule is simple: if the price exceeds the walkaway number, the property ceases to exist. I don't chase it. I don't negotiate post-auction. I find the next one 4.

There's always a next one.

The pre-auction work that actually wins

Here's a secret that most buyers don't realise: the best deals at auction are won before auction day.

I spend 80% of my time on pre-auction preparation and 20% on actual bidding. Here's what that preparation looks like:

Days 1-3: Due diligence. Read the Section 32 vendor's statement. Check the planning overlay. Verify the zoning — is it General Residential (GRZ), Neighbourhood Residential (NRZ), or something else? GRZ allows more intensive development. Verify flood overlays, heritage overlays, and any easements that restrict building 5.

Days 4-5: Physical inspection. Drive every street in a 500-metre radius. Note the neighbouring properties. Check for high-voltage power lines, major roads, industrial activity. Inspect the property itself — look at the foundations, check for structural cracking, test the plumbing pressure, open every cupboard and every manhole.

Days 6-7: Comparable analysis. Pull every sale in the last 12 months within 1 kilometre. Adjust for block size (price per square metre of land), dwelling quality, and development potential. Build a range: low estimate, fair value, high estimate.

Day 8: Financial modelling. Calculate the total investment (purchase price + stamp duty + renovation + granny flat build), project the rental income (both as-is and post-improvement), and compute the yield. If the yield at fair value doesn't hit our minimum threshold, we don't bid 6.

Day 9: Agent intel. Call the selling agent. Ask about vendor expectations, number of registered bidders, whether they'd consider a pre-auction offer. This call alone has saved my clients hundreds of thousands of dollars over the years. Agents talk. They reveal more than they should. And that information is gold at auction.

By auction day, I know more about the property than the vendor does. I know the exact width of the side access. I know the sewer connection point. I know whether the block allows a granny flat under the current planning scheme. That knowledge is my competitive advantage. Not courage. Not aggression. Knowledge.

The mistake that costs bidders $50,000

The most expensive mistake I see at auctions — and I see it almost every weekend — is bidding on the house instead of the land.

A bidder sees a beautifully renovated 4-bedroom house and thinks: "This is worth $850,000 because it's gorgeous." They bid emotionally, driven by the quality of the kitchen, the polished concrete floors, the landscaped garden.

Meanwhile, I'm looking at the same property and seeing: 550-square-metre block. No side access. Easement across the back third. Land value: $450,000. Building value: $250,000. Total value: $700,000.

The beautiful renovation added $100,000 to the building value but nothing to the land value. And buildings depreciate. In 20 years, that kitchen will need replacing again. Those polished floors will be scuffed. The garden will be overgrown.

But the land? The land will be worth $750,000 or more. Because there's no more land being made in established suburbs.

I buy ugly houses on big blocks. Every time. A $590,000 wreck on 600 square metres with termite damage and a kitchen from 1987 is a better investment than a $750,000 renovation on 400 square metres with no development potential. Because the ugly house gives me 600 square metres of land that I can develop — granny flat, rooming house conversion, future subdivision — while the renovated house gives me a depreciating building on a block too small to do anything with 7.

Our team bought a property in Hampton Park for $590,000. It was, frankly, a disaster. White ants. Leaking roof. Cracked foundations. But the block was 600+ square metres with side access. We fixed the structural issues for $25,000, renovated cosmetically for $15,000, and now it rents for $850 a week 8. Bank valued it at $670,000 four weeks after settlement.

The beautiful house next door, on a 380-square-metre block, sold for $720,000. Its rent? $520 a week. No granny flat potential. No development upside.

Ugly house, beautiful numbers. Beautiful house, ugly numbers. Pick one.

When to skip the auction entirely

Not every property needs to go to auction, and not every auction is worth attending.

I skip auctions when:

• The vendor's reserve is unrealistic. If the agent hints that the vendor wants $800K and my analysis says fair value is $720K, I don't waste my Saturday. I submit a pre-auction offer at $720K and let them come to me post-auction when it passes in.

• There are 8+ registered bidders. High bidder counts create price inflation through emotional competition. The winning price at a 10-bidder auction is typically 5-8% above fair value 1. That premium is too rich.

• The property is off-market. Roughly 30% of the properties we buy for clients never hit the public market. We source them through our agent network before they're listed. No auction, no competition, no emotional pricing. Just negotiation between a motivated seller and a prepared buyer 9.

Off-market deals are where the real money is made. But they require something most investors don't have: relationships. We settle properties fast, we don't renegotiate after inspections, and we close when we say we'll close. That reputation means agents bring us opportunities before they list them. It took years to build that network. But once it's built, it's the single most valuable asset in the business.

Auctions are theatre. They're designed to benefit sellers and agents, not buyers. I participate when I have to, but I'd rather negotiate privately every single time.

Learn the auction game. Master it. Then figure out how to avoid it altogether.
