Northwood is a smaller community of 916 — about 17% of the New South Wales suburb median (5,325) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $260,624/year runs 167% above the New South Wales suburb median of $97,552, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Median weekly rent of $1,200 equates to $5,200/month — about 124% of the median mortgage repayment of $4,200/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. At 5 km from the Sydney CBD, Northwood sits inside the high-demand inner ring — properties here compete directly with the city's employment, transport and amenity networks.

That score is driven by a population of 916, median household income of $260,624/year and median weekly rent of $1,200. 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.

Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Northwood has a usual resident population of approximately 916, compared with a New South Wales suburb median of 5,325 — placing it in the lower half of the state's suburbs by size.

The median monthly mortgage repayment in Northwood is $4,200, or approximately $50,400/year (vs $2,167/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 $1,200 works out to $5,200/month, covering 124% of the median mortgage repayment of $4,200/month. That means rent exceeds the median repayment by roughly $1,000/month, so on these numbers Northwood leans cash-flow-positive before accounting for strata, council rates, insurance and maintenance. 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 (916 residents), interest-rate sensitivity on the $4,200 median mortgage, the broader New South Wales market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
