Investment overview
Gross rental yield on houses sits at 2.63% (median rent $1015/wk against a $2,005,000 price tag). Units yield 8.74% gross, often the better cash-flow play for first-time investors. Renter share is modest (7%), so the rental pool is smaller and tenant demand can be patchier than in higher-density suburbs. The 12-month growth of +5.5% adds a capital-growth case on top of the yield.
