The short version
- Auctions legally bind winners to buy immediately - you must complete all checks before bidding.
- Pre-auction conditional offers rarely work - sellers won't cancel an auction for uncertain buyers.
- Spending $1000-$1500 on due diligence (reports, valuation, legal checks) is non-refundable if you don't bid or win.
- Many first-home buyers now wait for properties to be 'passed in' so they can make conditional offers.
Why auctions are high-risk for buyers
Winning an auction means legally committing to buy the property immediately, with no finance or building report conditions allowed. Unlike normal home purchases where you can include these conditions in your offer, auctions require you to complete all checks beforehand - which costs money whether you win or not.
Aaron notes this is particularly unfair for first-home buyers, who often don't realise they're spending $1000-$1500 on reports and valuations before even knowing if they'll bid. Many Auckland properties sell at auction, but he argues some shouldn't be listed this way - especially homes needing major due diligence like unconsented work or plaster cladding.
Smart preparation before auction day
To bid confidently, you need: 1) A completed building report identifying structural issues, 2) Legal review of the title, LIM and auction documents, 3) Bank pre-approval for that specific property (possibly requiring a paid valuation), and 4) Immediate access to your deposit (with KiwiSaver withdrawals arranged 10+ days ahead).
Aaron recommends asking the agent probing questions: Why are they selling? What are comparable sales? This helps gauge if the seller's reserve price is realistic. Without this intel, you risk spending on due diligence only to discover the property sells for $200k beyond your budget (as happened at Aaron's first auction).
What happens when auctions fail
If bidding doesn't meet the seller's reserve price (or nobody bids), the property is 'passed in'. This switches the sale method to standard negotiation - where conditional offers become possible. Many first-home buyers now intentionally wait for this moment to avoid auction risks.
Pre-auction offers can sometimes work, but Aaron explains why conditional ones almost never do: sellers won't cancel an auction for an uncertain buyer. His blunt advice? 'Unless you're ready to buy unconditionally, don't bother with pre-auction offers - the agent just wants to show the seller there's interest.'
