6,696 residents places Cooloongup squarely in the middle of the Western Australia suburb size distribution (state median 5,605), with market depth comparable to most WA localities. Cooloongup's median household income of $62,764/year is 37% below the Western Australia suburb median ($99,736) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. Median weekly rent of $300 equates to $1,300/month — about 99% of the median mortgage repayment of $1,313/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. At 39 km from Perth, Cooloongup is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price.
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 25% of household income — a useful sanity check on tenant affordability.

Limited buy-and-hold upside: household incomes 37% below the WA median ($62,764 vs $99,736) means liquidity is thin and capital growth tends to lag the wider Western Australia market over full cycles.
Strong rental coverage: $300/week (~$1,300/month) covers 99% of the $1,313/month median mortgage repayment, so the shortfall sits at just $13/month. Investors targeting positive cash flow should shortlist this suburb.
With 86% houses in a 6,696-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 Cooloongup is $1,313, or approximately $15,756/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 $300 works out to $1,300/month, covering 99% of the median mortgage repayment of $1,313/month. That leaves a $13/month shortfall (around $156/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 interest-rate sensitivity on the $1,313 median mortgage, below-median household incomes ($62,764 vs $99,736 state median), 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.
