Bidding at a House Auction and How to Set Your Limit

Forty people in a front garden on a Saturday morning, and only three of them are going to bid. I called auctions for twelve years and that ratio barely moved. What also barely moved was the look on the face of the person who went 55,000 dollars past the number they had written down in the car, because the bidding was still alive at the moment they had expected it to be over.

That is the whole problem with buying at auction. The price discovery is honest, the process is quick, and the environment is designed to make a considered decision feel like a slow one. You are standing in public, the agent has told everyone the range, somebody else wants it, and the auctioneer is counting down a property you have already imagined living in. None of that is a trick. It is just a terrible place to decide how much money to spend.

What the auctioneer is doing while you stand there

The job has three parts, and knowing them removes most of the theatre. The first is to get bidding started at all, which is why an auctioneer will open with a number well under value and happily accept a bid under it. The second is to pass the reserve, since nothing can sell below it. The third is to extract the last few increments once the property is on the market.

The phrase to listen for is on the market, or I am selling. Until you hear it, the property is still below the seller's reserve and everything is practice. After it, the next bid buys the house. I have watched buyers hold back their best bid for a dramatic moment and realise, when the hammer fell, that the dramatic moment was two bids ago.

A vendor bid is the other thing that confuses people. The auctioneer can place one bid on behalf of the seller, usually announced as a vendor bid, to lift a stalled auction toward the reserve. It is legal and must be declared. It also tells you something useful: the reserve is still above that number, and whoever you thought you were bidding against may not exist. Reading how sellers set the reserve price from the other side of the table is worth an hour before you attend one.

Set the number before Saturday, in writing

Your limit should be decided on a weeknight, at a kitchen table, with the inspection reports open. There is nothing to work out on the day, because the day is where judgement goes.

1. Do the inspections first. A contract signed at auction is unconditional. No finance clause, no inspection clause, and in most states no cooling off at all, as the cooling off period explained here sets out. Spending 600 to 900 dollars on building and pest reports for a house you might not win is the cost of bidding at all, and the items worth acting on are in the inspection findings that actually matter.
2. Get unconditional finance approval, and ask the lender about valuation risk. Pre-approval is not approval. If a valuer comes in 40,000 under your winning bid, you make up the gap in cash, and that scenario is covered in what to do when the valuation lands below your offer.
3. Write two numbers down. Your walk away limit, and a second number about 1 or 2 percent higher, marked as a stretch you accept only if the first number is beaten by one increment. Most buyers who regret an auction had no second number, so the first one became elastic.
4. Have the deposit ready to move. Ten percent is standard and is payable on the day, although a 5 percent deposit is often negotiable if you ask the agent before the auction, in writing, not at 10:55 on the morning.
5. Register the night before and bring photo ID. Registration is compulsory in every state, takes five minutes, and gives you a bidder number. Doing it on arrival is fine, but it adds a small rush to a morning that does not need one.

Write the limit on paper and give it to whoever is with you. Sounds theatrical. It is the single habit that most reliably stopped the people I watched from overpaying, because saying a number out loud to another person turns it into a commitment rather than an intention.

Against the advice to bid late and quietly

The standard tip is to stay at the back, say nothing, let the enthusiastic bidders exhaust themselves, then step in near the end. It is repeated constantly, and from where I stood it rarely worked.

Here is what actually happened. Late entrants arrived into an auction whose rhythm was already set by someone else, usually at 10,000 dollar increments, and they either accepted that rhythm and paid it or made a smaller bid that the auctioneer declined to take. The buyers who did well were the ones bidding early and plainly, because they controlled the shape of the thing. An opening bid at a sensible number, then steady responses, tells the auctioneer you are serious and tells the other bidder there is no soft spot to probe.

The one tactical move I rate: drop the increment once you are past the reserve. If the bidding has been moving in 10,000 dollar steps and you are 20,000 from your limit, bid 2,000. Auctioneers will push back and ask for five, and you repeat your number. They take it far more often than they admit, because a live 2,000 dollar bid beats an auction that stops. Do that three times and you have bought 6,000 dollars of room you would otherwise have handed over in one step.

Where the quiet approach does help: if the property passes in without selling, the highest bidder usually gets the first right to negotiate with the seller. That is genuinely worth having, and it is a reason to make one bid even in an auction you expect to die early. A passed in property with your number on it is a negotiation; a passed in property with nobody's number on it is an open market again on Monday.

What the morning actually looks like

Arrive about twenty minutes early, do a last walk through, and look at who is holding a bidder card. Buyers' agents in jackets, neighbours in gardening clothes and people filming on their phones are all crowd. The three cards are your auction.

Expect the whole thing to last between four and nine minutes. If you win, you sign the contract there, usually on a folding table in the hallway, and pay the deposit that day by bank transfer or cheque. Settlement is whatever the contract says, commonly 42, 60 or 90 days, and it was fixed before you bid, which is one more reason to have read the contract during the week.

If you lose, write down the sale price and the address. Three of those in a notebook will teach you more about what your money buys in that suburb than any report, and the next time you stand in a front garden you will not need the auctioneer to tell you what the house is worth.

FAQ

Can I make an offer before auction day?

Often yes, and on a property with little interest it is worth trying. The seller can accept a pre auction offer, usually as an unconditional contract, so you still need finance and inspections finished first.

How much deposit do I need at a house auction?

Ten percent of the purchase price on the day is the default. A smaller deposit, commonly 5 percent, can be negotiated with the agent beforehand and noted on the contract.

Can I bid with a finance or inspection condition?

No. Auction contracts are unconditional once the hammer falls, which is why the reports and approvals have to be done in the week beforehand rather than after.

What happens if the property passes in?

It did not reach the reserve. The highest bidder is normally offered the first chance to negotiate with the seller, often on the spot, before the listing goes back on the market.
