For investors
Investment overview.
Gross rental yield on houses sits at 3.70% (median rent $700/wk against a $982,500 price tag). Renter share is modest (23%), 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.
