Melbourne, the capital of Victoria, is known as Australia’s auction capital, hosting 38% of Australia’s auctions in 2024. With a lot of properties in Melbourne going to auction, when and how much properties are sold via auction can be indicators of how well the property market is faring. To collect auction data from a particular suburb, I developed an Excel spreadsheet that allows me to record what properties are going on sale via auction, as well as when and how much they were sold for. I can use this data to gauge how well the property market in a particular suburb is faring, as well as how much properties of a particular type typically go for.
In this blog post, I will go through the Excel spreadsheet, showing you the data that I collect and how I collected it. I will then go through how I used the data to track what is happening in the property market of a particular suburb and property type.
Going through the Excel spreadsheet
The Excel spreadsheet is a place where I can record auction data for different properties. It has a number of columns where I can record different types of data. For each property, I record the following:
- Date added: The date that the property was added to the spreadsheet.
- Link: The link to the property advertisement (typically realestate.com.au). I can use the link to quickly access the specific property to see what it looks like, as well as when and how much it was sold for.
- Address: The address of the property being sold via auction.
- Type: The type of property being sold. The spreadsheet defines the following property types:
- House: A single residential building placed on a discrete piece of land.
- Apartment: A self-contained home that is part of a multi-level residential building.
- Unit/villa: A ground-level home that shares land with other units and/or a wall with a neighbouring unit(s)
- Townhouse: A tall, narrow house that is typically attached to other townhouses.
- # bedrooms and # bathrooms: The number of bedrooms and bathrooms in the property respectively.
- Auction date: The date that the auction was held.
- Lower range and upper range: The estimated lower and upper price ranges from the price guide (a document indicating how much the property may sell for, along with a list of similar properties that were recently sold).
- Asking price: The lowest price that the seller is prepared to accept. This typically appears when a property was not sold on auction day (i.e., it is passed in).
- Sold at: How the property was sold, consisting of the following categories:
- Auction: The property was sold on auction day, either in front of other bidders or behind closed doors.
- Passed in: The property was not sold on auction day, either in front of other bidders or behind closed doors.
- Post-auction: The property was sold within three business days after auction.
- Pre-auction: The property was sold before auction day.
- Private sale: The property was sold more than three business days after auction.
- Too late: The property was still not sold more than three weeks after auction day.
- Under offer: The seller is considering a buyer’s offer to purchase the property at an undisclosed price.
- Withdrawn: The property could not be found on realestate.com.au, either because there was currently no demand for the property or it was sold off market.
- Sold date: The date the property was sold.
- Actual price: How much the property was sold for.
The following columns are calculated for each property:
- Comparison: How the actual price compares to the upper price range.
- Lower: The property was sold under the upper range.
- Middle: The property was sold at the upper range.
- Higher: The property was sold over the price range.
- Money gap: The difference between the actual price and the upper price range. A positive number indicates the property was sold at a higher price than the range, while a negative number indicates the property was sold at a lower price.
- Days gap: Number of days between the sold date and the auction date.
As some property advertisements were regularly updated, I added these columns to the spreadsheet:
- Old auction date: The previous date that the auction was scheduled to be held. This is useful for tracking whether an auction was delayed or a property that was previously withdrawn is being sold via auction again.
- Old min and old max: The old lower and upper price ranges for the property. These are typically recorded whenever an agent is updating the price guide due to a lack of interest in the property or an offer was rejected.
Each spreadsheet compiles auction data for one suburb. Multiple spreadsheets can be set up in one Excel workbook to collect and track auction data across multiple suburbs.
How I collected the data
Every Sunday morning (the day after most auctions are run), I follow these steps to collect auction data from realestate.com.au:
- I enter the suburb that I want to look at auction listings, and set search parameters to look for specific properties in a particular suburb going on sale via auction.
- While I was looking for my first home, I set the following search parameters to look for specific property types being sold via auction:
- Property type: Townhouse, apartment & unit and villa
- Sale method: Auction
- Once I have set my search parameters and run the search, I copy and paste the URL to a comment in cell A1 (‘Date added’). In future weeks, I can click on the URL to quickly access the list of properties going on sale via auction with specific search parameters.
- I order the auction listings by ‘next auction’, going from the earliest auction to the latest auction.
- I go through the list of auctions in order, checking off the properties by shading the address in green:
- For auctions that have already been recorded on the spreadsheet, I check to make sure that the auction date and price range have not changed. If they have changed, I move the old date and price range to ‘old auction date’ and ‘old min’/‘old max’ respectively and record the new price range and/or dates.
- For auctions that have not appeared on the spreadsheet, I add the details onto the spreadsheet.
- Going to the spreadsheet, I go through auctions that have run in the past week and record whether the property has been sold or it is passed in, along with the sale method, the date that it was sold and the actual price (if it appears on the listing).
- In some cases, a sold price might not be quoted, instead saying ‘Contact agent’.
- That sold price may appear a few weeks later, either on realestate.com.au or on CoreLogic’s list of recent sales over the past three months (check https://www.corelogic.com.au/our-data/recent-sales?postcode=[insert postcode] – you will get a list of properties that were recently sold over 90 days).
- Afterwards, I go through the properties that are passed in or under offer and see whether the property was sold.
- If a ‘passed in’ or ‘under offer’ property has been sold, I record the sale results.
- If the property has not been sold more than 3 weeks after auction, I record ‘too late’ under the ‘sold at’ column and shade the URL in red. This tells me to stop updating details on the property as it would have been sold via private sale (unless it goes on sale via auction again).
- In a separate spreadsheet, I count the number of properties that have been sold under a particular category. I use the data to calculate the clearance rate, the proportion of properties going on sale via auction that have been sold at auction.
- Individual states have different rules for auctions and cooling-off periods (the period of time where you can cancel the sale if you have changed your mind). In Victoria, properties that are sold via auction, or 3 business days before or after an auction, do not get a cooling off period. This means the person purchases the property without any conditions.
- I use this definition to define the clearance rate as ‘the proportion of properties that have been sold during or around auction day’. I calculate this by adding the proportions of properties that have been sold pre-auction, auction or post-auction.
- I use the clearance rate to see how well the market is faring for a particular property type and suburb. According to Veronica Morgan’s Auction Ready book, in Melbourne:
- A clearance rate below 60% is a slow market – demand is low as there are not many buyers for a lot of properties. Consequently, property prices are likely to remain stagnant or even fall.
- A clearance rate between 60% and 70% is a balanced market – demand is reasonable as there is a balance between buyers and properties on sale. Property prices are likely to remain stable.
- A clearance rate above 70% is a rising market: Demand is high due to a lot of buyers competing for the few properties that are on sale. Due to the strong demand, property prices are likely to rise.
Results from my auction data
I was collecting auction data for different suburbs over August to December 2024 before I bought my first home. In this section, I wanted to present data of auctions that were held from 1st September to 30th November 2024 for Hawthorn, an inner city suburb 6km east of Melbourne. As I was only interested on strata properties such as apartments, units, townhouses and villas for my first home, I only collected auction data from these property types. I did not collect auction data from houses as they are a separate property market altogether. Also, I excluded five properties that were categorised under “Withdrawn” as it was unclear whether they were sold off market or were taken off the market.
Category | Number | Percentage |
---|---|---|
Pre-auction | 19 | 27 |
Auction | 30 | 42 |
Post-auction | 1 | 1 |
Too late | 3 | 4 |
Private sale | 18 | 25 |
Passed in | 0 | 0 |
TOTAL | 71 | ~100 |
Out of the 71 properties on realestate.com.au that went on sale via auction during the period, 42% of them were sold via auction, with another 27% selling before auction. Combined with the one property that was sold during the post-auction period, the clearance rate of strata properties in Hawthorn during the period was 70%. That clearance rate was high, indicating that it was a rising market. This is because property sales tend to peak in spring when a lot of properties go on sale and many buyers are on the market searching for property.

Plotting the number of days between the auction and sold dates, all properties sold via auction have a day gap of 0 days (as the property was sold on the same day as the auction). There was a sizable number of properties that were sold before auction, particularly within the 3 days before auction. Beyond the auction period, properties that were sold via private sale had day gaps that varied from 6 to 62 days after auction.

Looking at different sale methods, properties sold before auction had an approximately similar number of properties that were sold below or above the upper price range. For auction day though, property prices mostly exceeded the upper price range. This can either be because the price guide underestimated how much the property would sell for or someone bids at a high price to buy the property without knowing its inherent value. In contrast, properties sold via private sale were almost always sold below the upper price range. This is due to the negotiation process between the buyer and seller where the property price continually gets lower so that the buyer can purchase the property.
Conclusion
Creating this Excel spreadsheet and establishing a routine to check the status of auctions weekly have helped me stay up-to-date with how the property market is faring in a particular suburb. This allows me to gauge how competitive the property market might be for a specific property type in a particular suburb. It also allows me to set realistic price expectations for properties that I am looking to buy so that I can succeed in buying the property at auction without paying too much. This was how I managed to buy my first home via auction.
You can use the spreadsheet attached to this blog post to keep track of auctions in the suburb(s) you want to live in, as well as a sample auction spreadsheet. This will definitely help you in your research to see how competitive auctions are in the suburb(s) of interest and what properties might go to auction. Happy collecting!
