Investment overview
Gross rental yield on houses sits at 2.76% (median rent $1425/wk against a $2,682,500 price tag). Units yield 7.11% gross, often the better cash-flow play for first-time investors. Renter share is modest (18%), so the rental pool is smaller and tenant demand can be patchier than in higher-density suburbs. The 12-month growth of +6.2% adds a capital-growth case on top of the yield.
