Mount Barker Summit is a smaller community of 100 — about 3% of the South Australia suburb median (3,699) — so investors should factor in the narrower buyer pool and longer average time-on-market. At $84,500/year, household income in Mount Barker Summit is within 4% of the South Australia median ($80,964), placing the suburb firmly in the state's mainstream demographic band. Median rent of $335/week (~$1,452/month) covers only 56% of the median mortgage of $2,600/month — the remaining $1,148/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. At 33 km from Adelaide, Mount Barker Summit is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price.

Weak cash flow: $335/week rent covers only 56% of the $2,600/month median mortgage — a $1,148/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.

The most recent census recorded a median weekly rent of $335 in Mount Barker Summit, equating to approximately $17,420/year in gross rental income (state median $320/week).

The median monthly mortgage repayment in Mount Barker Summit is $2,600, or approximately $31,200/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 $335 works out to $1,452/month, covering 56% of the median mortgage repayment of $2,600/month. That leaves a $1,148/month shortfall (around $13,776/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 (100 residents), interest-rate sensitivity on the $2,600 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.
