Chapter 6 of 10 · Choose how to sell
Auction, private treaty or off-market
Each method has a natural habitat. The aim is to choose the one that suits your property and your local buyers, which isn’t always the one an agency uses most. Base it on evidence: your home, your suburb’s buyers and what’s selling around you now.
The method of sale shapes how buyers make their offers. Matched to your property and your market, it helps interested buyers come to a decision; mismatched, you can pay for an auction or a long campaign that doesn’t draw the buyers it needs. Our side-by-side of auction and private treaty goes deeper on the comparison.
Auction
How it works: a set campaign (usually four weeks), no advertised price or a guide only, public competition on the day, and an unconditional contract signed on the fall of the hammer with no cooling-off for the buyer in any state.
The case for: auctions create a deadline and visible competition, which makes them a strong way to discover the price of a scarce asset. When two emotionally invested bidders want the same house, the result can exceed any private negotiation. The unconditional contract removes finance and inspection risk at a stroke. And even a passed-in auction flushes out the genuine buyers for the negotiation that follows.
The case against: auctions need a crowd. With one bidder or none, a public pass-in can leave buyers seeing the home as a “failed” auction, and that impression tends to linger. Auction campaigns also cost more (auctioneer plus typically heavier advertising), and some buyers, especially finance-dependent ones, won’t bid because they can’t go unconditional. In a thin market, an auction is an expensive way to discover there’s no competition.
Where auctions actually work: Sydney, Melbourne and Canberra have deep auction cultures, with weekly clearance rates above 60 per cent in normal conditions. Brisbane and Adelaide use auctions selectively, mostly for inner suburbs and prestige stock, and the share has been growing. Perth, Hobart and Darwin remain overwhelmingly private-treaty markets. Within auction cities, auctions favour inner and middle-ring suburbs, properties that are scarce or hard to price (character homes, development sites, anything with a view), and price brackets where buyer depth is strong. A standard outer-suburban house in a private-treaty city usually gains little from an auction.
Reserve strategy: set the reserve the week of the auction, not the day you sign the agency agreement, and set it from campaign evidence: who’s requested contracts, what the buyer feedback bands say, what’s sold during your campaign. A reserve at the bottom of your genuine acceptable range lets the auction run; momentum stalls when the auctioneer has to halt and confer. Know the vendor-bid rules in your state (vendor bids must be announced), and decide your pass-in plan in advance: the highest bidder at a pass-in usually gets first right to negotiate, so brief your agent on your real floor before the day. Our auction guide covers the day itself.
Private treaty
How it works: you list at an advertised price (or range), buyers make offers, you negotiate. Around eight in ten Australian sales happen this way.
The case for: control and reach. You can negotiate terms as well as price, accept conditional offers from the biggest possible buyer pool, take your time, and quietly adjust strategy without a public verdict. Costs are lower and the process suits every market, hot or cold.
The case against: no deadline means buyers can stall, and the first advertised price does most of the work; get it wrong and you’ll be cutting it publicly three weeks later (Chapter 7’s first-two-weeks rule). Buyers also get cooling-off periods in most states, so a “sold” sticker can come unstuck.
Off-market
An off-market sale skips public advertising: the agent shops your property to their buyer database. The pitch is privacy, no campaign costs and a fast result. The reality check: price discovery needs exposure, and an off-market sale by definition has the least. You’re selling into one agent’s contact list, and the buyer knows there’s no visible competition. Genuine off-market premiums exist but are rare; quiet discounts are common.
Off-market suits sellers who value privacy or speed over reaching the widest pool of buyers, genuinely unique properties with a known shortlist of buyers, and a pre-campaign test run (“we’ll quietly offer it for two weeks before launch”). If an agent leads with an off-market buyer who is ready to pay strong money right now, ask the obvious question: strong compared with what? Without testing the market, neither of you knows.
Your checklist
- Estimate how many buyers are likely to compete for your home
- Check how comparable homes in your suburb sold in the last six months
- Ask what share of the agency’s last 20 sales used each method
- Auction: set the reserve the week of the auction, from the evidence of the sale campaign
- Private treaty: list at a price you’d accept
- Off-market: only if privacy or speed matters more to you than reaching the widest pool of buyers
