For investors
Investment overview.
Gross rental yield on houses sits at 3.37% (median rent $630/wk against a $972,500 price tag). Units yield 9.30% gross, often the better cash-flow play for first-time investors. Renter share is modest (26%), so the rental pool is smaller and tenant demand can be patchier than in higher-density suburbs. The 12-month growth of +18.6% adds a capital-growth case on top of the yield.
