4,768 residents places Lake Coogee squarely in the middle of the Western Australia suburb size distribution (state median 5,605), with market depth comparable to most WA localities. Households here earn $111,644/year on average — 12% above the WA suburb median of $99,736 — a modest premium that supports resilient owner-occupier demand. Rent of $400/week (87% coverage of the $2,000/month median mortgage) leaves a gap of roughly $267/month that a typical investor bridges with negative gearing, depreciation and capital growth. 21 km from Perth places Lake Coogee in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs.
This suburb suits long-term investors due to steady population growth and affordable entry prices. Look for established streets close to schools and shops rather than raw new-estate land. Local rents consume roughly 19% of household income — a useful sanity check on tenant affordability.

The median monthly mortgage repayment in Lake Coogee is $2,000, or approximately $24,000/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 $400 works out to $1,733/month, covering 87% of the median mortgage repayment of $2,000/month. That leaves a $267/month shortfall (around $3,204/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.
