Investment overview
Gross rental yield on houses sits at 3.38% (median rent $650/wk against a $1,000,000 price tag). Units yield 11.59% gross, often the better cash-flow play for first-time investors. Renter share is modest (14%), so the rental pool is smaller and tenant demand can be patchier than in higher-density suburbs. The 12-month growth of +13.6% adds a capital-growth case on top of the yield.
