Grosmont is a smaller community of 135 — about 2% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Households here earn $102,856/year on average — 14% above the QLD suburb median of $90,298 — a modest premium that supports resilient owner-occupier demand. The median weekly rent of $115 translates to approximately $5,980/year in gross rental income, setting the upper bound on yield before vacancy, rates, insurance and maintenance. Grosmont is 364 km from Brisbane, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

Limited buy-and-hold upside: a small population of 135 means liquidity is thin and capital growth tends to lag the wider Queensland market over full cycles.
Gross rent of $115/week (~$5,980/year) sets the yield ceiling. Cross-check against your purchase price to confirm whether this suburb hits the 4–5% gross yield most Australian investors target.
With 82% houses in a 135-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.
