Kalgup is a smaller community of 91 — about 2% 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 $136,500/year runs 37% 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. Weekly rent of $175 covers just 44% of the median $1,733/month mortgage repayment, leaving a $975/month gap — investors should only pursue this suburb with a clear capital-growth thesis and sufficient external income to fund the shortfall. Kalgup is 202 km from Perth, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

Limited buy-and-hold upside: a small population of 91 means liquidity is thin and capital growth tends to lag the wider Western Australia market over full cycles.
Weak cash flow: $175/week rent covers only 44% of the $1,733/month median mortgage — a $975/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
With 85% houses in a 91-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

Kalgup has a usual resident population of approximately 91, compared with a Western Australia suburb median of 5,605 — placing it in the lower half of the state's suburbs by size. Population is the clearest proxy for market depth: more residents mean more transactions and typically a shorter average days-on-market on resale.
Kalgup sits 202 km straight-line from the Perth CBD. This is a regional market where CBD distance is only indicative — local industry diversity and commute alternatives matter more.
The most recent census recorded a median weekly rent of $175 in Kalgup, equating to approximately $9,100/year in gross rental income (state median $350/week).

The median monthly mortgage repayment in Kalgup 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 $175 works out to $758/month, covering 44% of the median mortgage repayment of $1,733/month. That leaves a $975/month shortfall (around $11,700/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 (91 residents), 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.
