Seventeen Mile is a smaller community of 22 — about 0% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Seventeen Mile's median household income of $71,500/year is 21% 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. Seventeen Mile is 83 km from Brisbane, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 40% of dwellings are separate houses (vs 77% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.
