A scenario is not a probability
The weaker, expected and stronger paths are controlled research scenarios. They show how the outcome changes when growth differs; they do not claim a specific chance that each path will occur. The line chart is therefore a sensitivity tool rather than a promise.
The useful question is not “Which number is correct?” but “Would this purchase still be acceptable if growth is weaker and costs are higher?”
Why Sydney forecasts can change regime
Interest rates, credit availability, employment, migration, construction supply, planning decisions and buyer sentiment can change the relationship between past and future prices. COVID-era disruption is treated as a market regime rather than assumed to be a normal repeatable period.
Historical relationships are tested chronologically so the model does not learn from future information. Even so, a new shock can sit outside the historical range.
Use local evidence with macro context
City-wide headlines do not affect every suburb and property type equally. The site combines local settled-sale and rent evidence with scenario assumptions, while the market-trends view shows broader movement and coverage. A local estimate with weak evidence should not be rescued by a positive Sydney headline.
Forecasts become less precise as the horizon extends. Ten years provides more time for compounding but also more time for structural change.
What a credible forecast displays
- The starting price or price basis.
- The holding period and annual path, not only an end value.
- Weaker and stronger cases around the expected path.
- Costs, rent and finance assumptions used in profit.
- Historical model error, evidence strength and explicit exclusions.
