With 18,145 residents, Deer Park is one of Victoria's more populous suburbs — roughly 2.4× the state median of 7,416 — giving it a deep buyer and tenant pool that typically supports higher transaction volumes and shorter average days on market. Household income of $75,712/year is 20% below the Victoria median of $95,160, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Median weekly rent of $350 equates to $1,517/month — about 90% of the median mortgage repayment of $1,689/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. 18 km from Melbourne places Deer Park in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs.
Middle-ring locations like this one historically reward patient holders — focus on homes near catchment-zone schools and major transport. Local rents consume roughly 24% of household income — a useful sanity check on tenant affordability.

Limited buy-and-hold upside: household incomes 20% below the VIC median ($75,712 vs $95,160) means liquidity is thin and capital growth tends to lag the wider Victoria market over full cycles.
Strong rental coverage: $350/week (~$1,517/month) covers 90% of the $1,689/month median mortgage repayment, so the shortfall sits at just $172/month. Investors targeting positive cash flow should shortlist this suburb.
With 82% houses in a 18,145-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

That score is driven by a population of 18,145, median household income of $75,712/year and median weekly rent of $350.

Deer Park has a usual resident population of approximately 18,145, compared with a Victoria suburb median of 7,416 — placing it in the upper half of the state's suburbs by size.

The median monthly mortgage repayment in Deer Park is $1,689, or approximately $20,268/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 $350 works out to $1,517/month, covering 90% of the median mortgage repayment of $1,689/month. That leaves a $172/month shortfall (around $2,064/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 $1,689 median mortgage, below-median household incomes ($75,712 vs $95,160 state median), the broader Victoria market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
