Mount Crosby is a smaller community of 1,860 — about 34% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $155,636/year runs 72% above the Queensland suburb median of $90,298, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Median weekly rent of $478 equates to $2,071/month — about 99% of the median mortgage repayment of $2,095/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. 22 km from Brisbane places Mount Crosby in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs. Separate houses make up 95% of dwellings — 18 percentage points above the Queensland median of 77% — pointing to a family-oriented, land-rich market where value is concentrated in the underlying block.

A median weekly rent of $478 works out to $2,071/month, covering 99% of the median mortgage repayment of $2,095/month. That leaves a $24/month shortfall (around $288/year before tax benefits), so a typical owner-occupier-priced property here is negatively geared.
