Matta Flat is a smaller community of 82 — about 2% of the South Australia suburb median (3,699) — so investors should factor in the narrower buyer pool and longer average time-on-market. Household income of $68,224/year is 16% below the South Australia median of $80,964, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Median rent of $125/week (~$542/month) covers only 64% of the median mortgage of $845/month — the remaining $303/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. Matta Flat is 134 km from Adelaide, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

Limited buy-and-hold upside: a small population of 82 means liquidity is thin and capital growth tends to lag the wider South Australia market over full cycles.
Weak cash flow: $125/week rent covers only 64% of the $845/month median mortgage — a $303/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
With 78% houses in a 82-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

The most recent census recorded a median weekly rent of $125 in Matta Flat, equating to approximately $6,500/year in gross rental income (state median $320/week).

The median monthly mortgage repayment in Matta Flat is $845, or approximately $10,140/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 $125 works out to $542/month, covering 64% of the median mortgage repayment of $845/month. That leaves a $303/month shortfall (around $3,636/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 (82 residents), interest-rate sensitivity on the $845 median mortgage, below-median household incomes ($68,224 vs $80,964 state median), 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.
