Castle Creek is a smaller community of 85 — about 1% of the Victoria suburb median (7,416) — so investors should factor in the narrower buyer pool and longer average time-on-market. Households here earn $108,316/year on average — 14% above the VIC suburb median of $95,160 — a modest premium that supports resilient owner-occupier demand. Rent of $430/week (81% coverage of the $2,300/month median mortgage) leaves a gap of roughly $437/month that a typical investor bridges with negative gearing, depreciation and capital growth. Castle Creek is 245 km from Melbourne, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

That score is driven by a population of 85, median household income of $108,316/year and median weekly rent of $430.

Castle Creek has a usual resident population of approximately 85, compared with a Victoria suburb median of 7,416 — placing it in the lower half of the state's suburbs by size.

Castle Creek sits 245 km straight-line from the Melbourne 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 $430 in Castle Creek, equating to approximately $22,360/year in gross rental income (state median $380/week). Market rents have typically drifted above the recorded figure — verify against current listings on realestate.com.au and Domain before making an offer.
The median monthly mortgage repayment in Castle Creek is $2,300, or approximately $27,600/year (vs $1,950/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 $430 works out to $1,863/month, covering 81% of the median mortgage repayment of $2,300/month. That leaves a $437/month shortfall (around $5,244/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 (85 residents), interest-rate sensitivity on the $2,300 median mortgage, the broader Victoria market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
