South Hummocks is a smaller community of 30 — 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 $97,500/year runs 20% 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 weekly rent of $230 equates to $997/month — about 95% of the median mortgage repayment of $1,051/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. South Hummocks is 109 km from Adelaide, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

The median monthly mortgage repayment in South Hummocks is $1,051, or approximately $12,612/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 $230 works out to $997/month, covering 95% of the median mortgage repayment of $1,051/month. That leaves a $54/month shortfall (around $648/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 (30 residents), interest-rate sensitivity on the $1,051 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.
