Cardup is a smaller community of 1,163 — about 21% of the Western Australia suburb median (5,605) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $137,540/year runs 38% above the Western Australia suburb median of $99,736, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Median weekly rent of $500 equates to $2,167/month — about 91% of the median mortgage repayment of $2,383/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. At 35 km from Perth, Cardup is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price. Separate houses make up 95% of dwellings — 16 percentage points above the Western Australia median of 79% — pointing to a family-oriented, land-rich market where value is concentrated in the underlying block.

Strong rental coverage: $500/week (~$2,167/month) covers 91% of the $2,383/month median mortgage repayment, so the shortfall sits at just $216/month. Investors targeting positive cash flow should shortlist this suburb.
With 95% houses in a 1,163-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 Cardup is $2,383, or approximately $28,596/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 $500 works out to $2,167/month, covering 91% of the median mortgage repayment of $2,383/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 a thin buyer pool (1,163 residents), interest-rate sensitivity on the $2,383 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.
