For investors

Investment overview.

Gross rental yield on houses sits at 4.68% (median rent $810/wk against a $900,000 price tag). Units yield 11.21% gross, often the better cash-flow play for first-time investors. Renter share is modest (22%), so the rental pool is smaller and tenant demand can be patchier than in higher-density suburbs. The 12-month growth of +9.8% adds a capital-growth case on top of the yield.
