SEIFA deciles have a well-documented relationship with long-run property price growth in Sydney. Higher-decile suburbs tend to retain value better during downturns and recover faster after corrections, reflecting the financial resilience of owner-occupiers. Lower-decile suburbs can deliver strong growth during boom phases as affordability pressure pushes buyers further from the city, but they are typically more volatile.
