For investors
Investment overview.
Gross rental yield on houses sits at 3.72% (median rent $640/wk against a $895,500 price tag). Units yield 7.43% gross, often the better cash-flow play for first-time investors. Renter share is modest (11%), so the rental pool is smaller and tenant demand can be patchier than in higher-density suburbs. The 12-month growth of +14.2% adds a capital-growth case on top of the yield.
