Roundstone is a smaller community of 78 — about 1% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Roundstone's median household income of $61,724/year is 32% below the Queensland suburb median ($90,298) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. The median weekly rent of $200 translates to approximately $10,400/year in gross rental income, setting the upper bound on yield before vacancy, rates, insurance and maintenance. Roundstone is 442 km from Brisbane, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Separate houses make up 92% of dwellings — 15 percentage points above the Queensland median of 77% — pointing to a family-oriented, land-rich market where value is concentrated in the underlying block.

Limited buy-and-hold upside: a small population of 78 means liquidity is thin and capital growth tends to lag the wider Queensland market over full cycles.
Gross rent of $200/week (~$10,400/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 92% houses in a 78-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

The main risks are a thin buyer pool (78 residents), interest-rate sensitivity, below-median household incomes ($61,724 vs $90,298 state median), the broader Queensland market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
