Buying a Property at Auction: A Guide for Home Buyers

How Does a Property Auction Work?

A property auction is a public sale where registered bidders compete to purchase a property.

The seller usually sets a reserve price, which is the minimum amount they are prepared to accept. If bidding reaches the reserve, the property may be announced as “on the market”. The highest bidder at the fall of the hammer will generally become the purchaser.

If the reserve is not reached, the property may be passed in. The highest bidder may then be invited to negotiate with the seller.

Auction procedures and buyer rights vary between states and territories, so obtain legal advice about the rules applying to the property.

Why Is Buying at Auction Different?

Auction purchases are commonly unconditional.

With a private sale, a buyer may be able to include conditions for finance, building and pest inspections or due diligence. At auction, these checks usually need to be completed before bidding.

There is generally no cooling-off period for a property purchased at auction. In Queensland, the standard residential cooling-off period does not apply to auction purchases, with similar exclusions applying in other Australian jurisdictions.

If your bid is successful, you may still need to complete the purchase even if:

• Your lender later declines the application

• The valuation is lower than your winning bid

• An inspection identifies problems

• Your circumstances change before settlement

Do not bid unless you are comfortable with the financial and legal commitment.

Confirm Your Borrowing Capacity

Before attending an auction, speak with your mortgage broker about your borrowing capacity.

Your broker will generally review your income, expenses, existing debts, deposit, credit position and expected purchase costs.

Your maximum borrowing capacity is not necessarily the amount you should bid. Your budget should also allow for:

• Transfer duty or stamp duty

• Legal and conveyancing fees

• Building and pest inspections

• Registration and settlement costs

• Insurance

• Moving expenses

• Immediate repairs

• An emergency buffer

Decide what repayment level feels manageable rather than simply relying on the maximum amount available.

Obtain Home Loan Pre-Approval

Pre-approval can provide an indication of how much a lender may be prepared to lend based on your financial position at that time. It can help you establish a realistic search range before attending auctions.

Pre-approval does not commit you to a loan or guarantee final approval. The lender may still need to assess the property, final purchase price, valuation and any changes to your financial circumstances.

Before bidding, send the property address and expected price range to your broker. Some properties may attract additional restrictions, including small apartments, rural properties, unusual titles, high-density developments or properties requiring major repairs.

An early review may identify potential concerns, but it cannot guarantee the lender will accept the property or final price.

Research the Property and Market

Review recent settled sales of comparable properties in the area.

Consider differences in:

• Land and building size

• Property condition

• Renovations

• Bedrooms and bathrooms

• Parking

• Street position

• Local amenities

• Date of sale

Online estimates and the agent’s advertised guide should only be treated as general indicators.

Set your own view of value based on comparable sales, professional advice and the property’s condition rather than assuming it will be worth your highest bid.

Have the Contract Reviewed

Request the auction contract as early as possible and have it reviewed by a solicitor or conveyancer.

Your legal representative may examine:

• Title details

• Easements and encumbrances

• Settlement date

• Deposit requirements

• Included fixtures

• Special conditions

• Body corporate records

• Tenancy arrangements

• Default provisions

They can also explain the legal consequences of becoming the successful bidder and recommend any searches that should be completed before auction day.

Government consumer guidance recommends having the contract reviewed by a solicitor or conveyancer before signing or bidding.

Do not leave the contract review until the auction begins.

Arrange Building and Pest Inspections

Because an auction purchase is commonly unconditional, building and pest inspections should generally be completed before bidding.

A professional inspection may identify structural defects, termite activity, moisture damage, roof issues, drainage concerns or significant maintenance requirements.

A property valuation is not a substitute for these inspections. A valuation primarily assesses market value and mortgage security, while building and pest reports focus on the property’s physical condition.

Use the findings to decide whether to bid and to set your maximum price.

Understand the Deposit

Check the contract to confirm the required deposit, payment deadline and accepted payment method.

The successful bidder is generally expected to sign the contract and pay the deposit on auction day. Government guidance notes that the deposit is often 10%, although another amount may be agreed.

Before the auction:

• Confirm your transfer limit

• Check whether electronic transfer or bank cheque is accepted

• Discuss any alternative deposit arrangement in advance

• Keep the funds readily available

Verify payment instructions independently before transferring money.

Set a Firm Maximum Bid

Decide your maximum bid before the auction begins.

Your limit should consider:

• Your approved borrowing range

• Available deposit

• Purchase costs

• Comparable sales

• Inspection findings

• Expected repairs

• Your financial buffer

• The risk of a low valuation

Auction competition can make small increases feel harmless, but several extra bids can add tens of thousands of dollars to the purchase price.

Write down your limit and stop when it is reached.

What if the Valuation Is Lower Than Your Bid?

A lender may value the property below the amount you agreed to pay.

For example, if you purchase for $850,000 but the accepted valuation is $800,000, the lender may calculate the loan-to-value ratio using the lower figure.

You may then need to:

• Contribute a larger deposit

• Pay lenders mortgage insurance

• Reduce the requested loan amount

• Arrange another acceptable funding solution

Because an auction contract is commonly unconditional, a low valuation may not allow you to cancel the purchase.

Keeping a financial buffer can reduce the risk of being unable to complete settlement.

Bidding at the Auction

You will generally need to register and provide identification before bidding. The exact registration rules depend on the state or territory in which the property is located.

During the auction:

• Stand where the auctioneer can see you

• Bid clearly

• Keep track of the current price

• Ask for clarification if you are unsure

• Ignore pressure from the crowd

• Stop at your maximum

You may be able to appoint another person, such as a buyer’s agent, to bid for you. Confirm the registration and authority requirements beforehand.

When the auctioneer announces that the property is “on the market”, it generally means the reserve has been reached and the property is expected to sell to the highest bidder.

What Happens if the Property Is Passed In?

If bidding does not reach the reserve, the property may be passed in.

The highest bidder may be invited to negotiate with the seller. This can create an opportunity to discuss the price and, depending on the circumstances, other contract terms.

Be careful about signing immediately after an unsuccessful auction. Cooling-off rights can be restricted for certain post-auction contracts.

In Queensland, the cooling-off period does not apply where a registered bidder enters into a private treaty contract within two business days of an unsuccessful auction for that property.

Have your solicitor or conveyancer explain your position before signing.

What Happens After You Win?

If you are the successful bidder, you will generally:

1. Sign the contract.

2. Pay the required deposit.

3. Send the contract to your broker and conveyancer.

4. Progress the loan to formal approval.

5. Arrange insurance as advised.

6. Sign the loan documents.

7. Provide your remaining contribution.

8. Complete settlement.

Send the contract to your broker immediately so the valuation and formal approval process can begin.

Continue meeting all existing repayments and avoid applying for new credit before settlement.

Common Auction Mistakes

Common mistakes include:

• Bidding without pre-approval

• Assuming pre-approval guarantees finance

• Skipping the contract review

• Failing to arrange inspections

• Forgetting purchase costs

• Relying only on the price guide

• Bidding above an affordable limit

• Not preparing the deposit

• Taking out new debt before settlement

Preparation is the best protection against making an emotional or unaffordable decision.

Frequently Asked Questions

Can I bid subject to finance?

Auction bids are commonly unconditional. You generally cannot add a finance condition after winning unless a different arrangement was agreed before the auction.

Does pre-approval guarantee finance?

No. The lender must still accept the property, valuation and final price and confirm that your circumstances have not changed.

Is there a cooling-off period?

Generally, no. Queensland, NSW and Victoria exclude auction purchases from their standard cooling-off arrangements.

How much deposit is required?

The amount is set out in the contract and is generally payable immediately after the auction. Confirm the amount and payment method before bidding.

Can someone bid on my behalf?

Another person may be able to bid for you, but registration and written authority requirements may apply. Confirm the process with the selling agent before auction day.

Can I make an offer before auction day?

You can ask whether the seller will consider a pre-auction offer. Have the contract reviewed and confirm whether cooling-off rights apply before signing.
