06 Nov Sydney Suburbs Where Property Values Have Doubled: Do Houses & Units Appreciate Equally?

When it comes to Sydney property investment, not all suburbs—and not all property types—deliver the same returns. While some areas have seen property values double in a relatively short period, the difference between houses and units can be significant. Understanding these variations is crucial for both investors and owner occupiers wanting to make informed decisions. This article explores which Sydney suburbs have experienced substantial growth and how houses and units within these areas have performed differently.

The data reveals a clear difference in the rate at which property values double for houses versus units across Sydney’s key regions, underscoring the importance of property type in investment decisions. For example, in the Lower North Shore suburb of Mosman, where the mix is relatively balanced with 46% houses and 52% units, Mosman houses appreciate faster—doubling in value every 9 years compared to 13 years for units. Similarly, in Neutral Bay, houses double in value in 11 years, while units take 12 years. In suburbs with a higher density of units, like Cremorne Point and Kirribilli, where demand for units is higher, units appreciate much faster than houses. As buyers agents’ we understand that both location and property type significantly influence capital growth potential—crucial information for property investors considering their next purchase.

Meanwhile, the Upper North Shore and Eastern Suburbs present a more varied picture. In the Upper North Shore, house prices across Pymble, Roseville, Gordon, and Killara have doubled in 9 years, but units in the same suburbs took anywhere from 16 to 22 years to double. Properties in the Eastern Suburbs reflect the fastest growth overall, with houses in Double Bay doubling in just 5 years. In contrast, unit prices in these exclusive suburbs, though still performing very well, mostly doubled in 10 to 11 years.
