South Turramurra is a smaller community of 3,208 — about 60% of the New South Wales suburb median (5,325) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $179,244/year runs 84% above the New South Wales suburb median of $97,552, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Median weekly rent of $795 equates to $3,445/month — about 98% of the median mortgage repayment of $3,500/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. 16 km from Sydney places South Turramurra in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs. Separate houses make up 95% of dwellings — 19 percentage points above the New South Wales median of 76% — pointing to a family-oriented, land-rich market where value is concentrated in the underlying block.
Middle-ring locations like this one historically reward patient holders — focus on homes near catchment-zone schools and major transport. Local rents consume roughly 23% of household income — a useful sanity check on tenant affordability.

The median monthly mortgage repayment in South Turramurra is $3,500, or approximately $42,000/year (vs $2,167/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 $795 works out to $3,445/month, covering 98% of the median mortgage repayment of $3,500/month. That leaves a $55/month shortfall (around $660/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 (3,208 residents), interest-rate sensitivity on the $3,500 median mortgage, the broader New South Wales market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
