Steelton is a smaller community of 31 — about 1% of the South Australia suburb median (3,699) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $143,000/year runs 77% above the South Australia suburb median of $80,964, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. The median weekly rent of $100 translates to approximately $5,200/year in gross rental income, setting the upper bound on yield before vacancy, rates, insurance and maintenance. Steelton is 100 km from Adelaide, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 54% of dwellings are separate houses (vs 73% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.
