The proportion of renters in Castle Hill reflects both the housing type mix (units and smaller dwellings attract renters) and the economic accessibility of the suburb. A high renter proportion is normal and positive for investors; it can also indicate a younger, more transient population, which affects the character of the area and the tenant pool. Owner-occupier-dominated suburbs tend to have more stable communities and better-maintained streetscapes.
