With 13,904 residents, Clarkson is one of Western Australia's more populous suburbs — roughly 2.5× the state median of 5,605 — giving it a deep buyer and tenant pool that typically supports higher transaction volumes and shorter average days on market. Household income of $91,572/year is 8% below the Western Australia median of $99,736, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Rent of $350/week (88% coverage of the $1,733/month median mortgage) leaves a gap of roughly $216/month that a typical investor bridges with negative gearing, depreciation and capital growth. At 32 km from Perth, Clarkson 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 looking for a balance of rental yield and capital growth. Schools and transport underpin family demand. Local rents consume roughly 20% of household income — a useful sanity check on tenant affordability.

The median monthly mortgage repayment in Clarkson is $1,733, or approximately $20,796/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 $350 works out to $1,517/month, covering 88% of the median mortgage repayment of $1,733/month. That leaves a $216/month shortfall (around $2,592/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 $1,733 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.
