Keith is a smaller community of 1,405 — about 38% 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 $67,288/year is 17% below the South Australia median of $80,964, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Median weekly rent of $180 equates to $780/month — about 101% of the median mortgage repayment of $773/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. Keith is 208 km from Adelaide, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Separate houses make up 89% of dwellings — 16 percentage points above the South Australia median of 73% — pointing to a family-oriented, land-rich market where value is concentrated in the underlying block.

Limited buy-and-hold upside: a small population of 1,405 means liquidity is thin and capital growth tends to lag the wider South Australia market over full cycles.
Strong rental coverage: $180/week (~$780/month) covers 101% of the $773/month median mortgage repayment, so the shortfall sits at just $0/month. Investors targeting positive cash flow should shortlist this suburb.
With 89% houses in a 1,405-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

The median monthly mortgage repayment in Keith is $773, or approximately $9,276/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 $180 works out to $780/month, covering 101% of the median mortgage repayment of $773/month. That means rent exceeds the median repayment by roughly $7/month, so on these numbers Keith leans cash-flow-positive before accounting for strata, council rates, insurance and maintenance. 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 (1,405 residents), interest-rate sensitivity on the $773 median mortgage, below-median household incomes ($67,288 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.
