Coomberdale is a smaller community of 56 — 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. Household income of $86,632/year is 13% below the Western Australia median of $99,736, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Median weekly rent of $250 equates to $1,083/month — about 1083% of the median mortgage repayment of $100/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. Coomberdale is 166 km from Perth, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

The median monthly mortgage repayment in Coomberdale is $100, or approximately $1,200/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 $250 works out to $1,083/month, covering 1083% of the median mortgage repayment of $100/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 (56 residents), interest-rate sensitivity on the $100 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.
