Yanchep's population of 11,022 sits 97% above the Western Australia suburb median of 5,605, giving it a wider tenant and buyer catchment than the average WA locality. Household income of $88,348/year is 11% 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 $340/week (80% coverage of the $1,842/month median mortgage) leaves a gap of roughly $369/month that a typical investor bridges with negative gearing, depreciation and capital growth. At 49 km from Perth, Yanchep is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price.
Middle-ring locations like this one historically reward patient holders — focus on homes near catchment-zone schools and major transport. Local rents consume roughly 20% of household income — a useful sanity check on tenant affordability.

The median monthly mortgage repayment in Yanchep is $1,842, or approximately $22,104/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 $340 works out to $1,473/month, covering 80% of the median mortgage repayment of $1,842/month. That leaves a $369/month shortfall (around $4,428/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.
