Set your own anchor before the agent sets one for you
Most buyers walk into a property search with no independent sense of what a home is worth. They open realestate.com.au, see a , and every judgment that follows is tethered to that number. Awareness of anchoring does not stop it from working — only a pre-existing number of your own does. This step gives you a repeatable process for building that number from recent , using free Australian tools, so you arrive at an open inspection already knowing what the property is worth.
- Buyers cite the agent's price guide as their first source of pricing information in most searches .
- The Northcraft and Neale anchoring study found listing prices shifted property valuations by up to 11% in either direction, even among experienced real estate professionals .
Yet most buyers get their first price signal from the agent — the very person whose job it is to generate competition. That number becomes the anchor, and no amount of willpower overrides it. The only reliable defence is a process that produces your number first.
The fix is a written valuation you build before any agent interaction
Your brain latches onto the first number it encounters. If that first number comes from your own research — grounded in actual sale prices of similar properties — it becomes your anchor. When the agent then quotes a different figure, your brain treats it as a deviation from your anchor rather than the starting point.
You need a minimum of three comps. Five is better. The more data points you have, the harder it is for any single number to distort your thinking. The characteristics you want to match across each comp:
Factor | What to Match |
|---|---|
Location | Same suburb, or adjacent suburb with similar profile |
Property type | House to house, unit to unit, townhouse to townhouse |
Bedrooms and bathrooms | Same count, or within one |
Land size | Within 15-20% of the target property |
Condition | Similar age, renovation level, and presentation |
Sale date | Sold within the last 3 to 6 months |
You do not need to pay for property data. The "Sold" section on realestate.com.au is your primary tool — filter by suburb, property type, bedrooms, and price range. Domain's Research section draws from the same dataset agents use through PriceFinder. Several state governments also publish free official sales data sourced from settlement documents, which captures every sale, not just listed ones (see the state-specific section below).
Adjust each comp, then take the middle of the cluster
No two properties are identical, so you adjust each comp to account for the differences between it and your target. The adjustments do not need to be precise to the dollar — you are building a reasonable range, not a bank valuation. Use these rough guides:
- Extra bedroom: Add 5-8% to the sale price of a comp with fewer bedrooms .
- Larger land: For a block 50-100 sqm larger, add 3-5% in established suburbs where land is scarce. In outer suburbs with bigger lots, the premium is smaller.
- Renovation vs original condition: A full renovation (kitchen, bathroom, flooring) can add 10-15% over an equivalent original-condition property . A partial renovation sits somewhere in between.
- Off-street parking: A garage or carport adds $20,000-$50,000 depending on the suburb and how scarce parking is.
Apply these adjustments to each comp. If a 4-bedroom comparable sold for $1,180,000, adjust down 5-8% to estimate what it would have sold for as a 3-bedroom — roughly $1,085,000 to $1,120,000.
Once you have your adjusted figures, ignore the highest and the lowest. The cluster in the middle is your . That is your independent assessment of what this property is worth.
Now set your maximum price. This is not the top of the range — it is the most you can afford to pay without financial stress. If your borrowing capacity and deposit support a maximum of $1,150,000, that is your ceiling regardless of what the comps suggest.
