Kingston Park is a smaller community of 623 — about 17% 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 $99,320/year runs 23% 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. Median rent of $340/week (~$1,473/month) covers only 68% of the median mortgage of $2,167/month — the remaining $694/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. 14 km from Adelaide places Kingston Park in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs. Only 55% 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.

That score is driven by a population of 623, median household income of $99,320/year and median weekly rent of $340.

Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Kingston Park has a usual resident population of approximately 623, compared with a South Australia suburb median of 3,699 — placing it in the lower half of the state's suburbs by size.

The median monthly mortgage repayment in Kingston Park is $2,167, or approximately $26,004/year (vs $1,616/month state median). Stress-test your own borrowing at rates 1–2 percentage points above today's to make sure you can still service the loan through an RBA tightening cycle.
A median weekly rent of $340 works out to $1,473/month, covering 68% of the median mortgage repayment of $2,167/month. That leaves a $694/month shortfall (around $8,328/year before tax benefits), so a typical owner-occupier-priced property here is negatively geared. Actual cash flow depends on your deposit, loan terms, ownership costs and marginal tax rate — run the full numbers in our rental yield calculator.
The main risks are a thin buyer pool (623 residents), interest-rate sensitivity on the $2,167 median mortgage, the broader South Australia market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
