Lake Toolbrunup is a smaller community of 76 — about 1% of the Western Australia suburb median (5,605) — so investors should factor in the narrower buyer pool and longer average time-on-market. At $97,500/year, household income in Lake Toolbrunup is within 2% of the Western Australia median ($99,736), placing the suburb firmly in the state's mainstream demographic band. Weekly rent of $75 covers just 42% of the median $774/month mortgage repayment, leaving a $449/month gap — investors should only pursue this suburb with a clear capital-growth thesis and sufficient external income to fund the shortfall. Lake Toolbrunup is 308 km from Perth, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

Weak cash flow: $75/week rent covers only 42% of the $774/month median mortgage — a $449/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.

The median monthly mortgage repayment in Lake Toolbrunup is $774, or approximately $9,288/year (vs $1,902/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 $75 works out to $325/month, covering 42% of the median mortgage repayment of $774/month.

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 (76 residents), interest-rate sensitivity on the $774 median mortgage, the broader Western Australia market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
