Start with the question you are actually asking
A seller's asking price, a suburb's typical recent price and an estimate for one dwelling are different numbers. A listing URL can identify the address and visible facts, but a withheld price is not evidence. The tool therefore reports the price basis it used and labels a suburb benchmark when property-level evidence is not sufficient.
Use the result to decide what to investigate next—not as a substitute for a valuation, contract review, building inspection or negotiation advice.
What evidence matters most
Recent settled sales are stronger evidence than advertised prices because they show what buyers actually paid. The checker groups sales by Sydney locality and postcode, requires a minimum evidence level for recommendations and avoids letting one unusual transaction dominate the result.
Property type, bedrooms, bathrooms, parking, land, condition, floor position, views, strata, title and exact location can still create a wide difference within one suburb. Missing facts widen uncertainty.
Read the error range before the headline
The site displays the relevant historical model-error band for supported price ranges. This is the typical observed difference on later sales that were not used to fit the model. It is not a guarantee that an individual estimate will fall inside the same range.
Premium properties above $3 million currently receive no public recommendation because historical error is materially higher. That restraint is more useful than a precise-looking number with weak evidence.
A sensible five-minute check
- Enter the address or a public listing URL and add the asking price when it is known.
- Confirm whether the evidence is an exact locality match or a postcode proxy.
- Compare the price basis with recent settled-sale counts and the displayed error range.
- Review weaker and stronger cases, then independently inspect the specific property attributes.
