For investors
Investment overview.
Gross rental yield on houses sits at 3.05% (median rent $625/wk against a $1,066,000 price tag). Units yield 10.83% gross, often the better cash-flow play for first-time investors. Renter share is modest (10%), so the rental pool is smaller and tenant demand can be patchier than in higher-density suburbs. The 12-month growth of +6.6% adds a capital-growth case on top of the yield.
