6,714 residents places Oak Park squarely in the middle of the Victoria suburb size distribution (state median 7,416), with market depth comparable to most VIC localities. Median household income of $114,452/year runs 20% above the Victoria suburb median of $95,160, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Rent of $401/week (80% coverage of the $2,167/month median mortgage) leaves a gap of roughly $429/month that a typical investor bridges with negative gearing, depreciation and capital growth. 11 km from Melbourne places Oak 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. Only 51% of dwellings are separate houses (vs 78% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.
This suburb suits long-term investors looking for a balance of rental yield and capital growth. Schools and transport underpin family demand. Local rents consume roughly 18% of household income — a useful sanity check on tenant affordability.

That score is driven by a population of 6,714, median household income of $114,452/year and median weekly rent of $401. Whether it fits your portfolio depends on whether you are targeting cash flow, capital growth, or a value-add renovation — all three are scored with suburb-specific numbers elsewhere on this page.

The median monthly mortgage repayment in Oak Park is $2,167, or approximately $26,004/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 $401 works out to $1,738/month, covering 80% of the median mortgage repayment of $2,167/month. That leaves a $429/month shortfall (around $5,148/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.
