Outer Harbor is a smaller community of 13 — about 0% of the South Australia suburb median (3,699) — so investors should factor in the narrower buyer pool and longer average time-on-market. Outer Harbor's median household income of $55,848/year is 31% below the South Australia suburb median ($80,964) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. The median weekly rent of $102 translates to approximately $5,304/year in gross rental income, setting the upper bound on yield before vacancy, rates, insurance and maintenance. 19 km from Adelaide places Outer Harbor in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs.
