With 12,867 residents, Gladesville is one of New South Wales's more populous suburbs — roughly 2.4× the state median of 5,325 — giving it a deep buyer and tenant pool that typically supports higher transaction volumes and shorter average days on market. Median household income of $117,364/year runs 20% 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. Rent of $450/week (70% coverage of the $2,800/month median mortgage) leaves a gap of roughly $850/month that a typical investor bridges with negative gearing, depreciation and capital growth. At 9 km from the Sydney CBD, Gladesville sits inside the high-demand inner ring — properties here compete directly with the city's employment, transport and amenity networks. Only 40% of dwellings are separate houses (vs 76% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.
Regional property can deliver strong cash-flow yields but liquidity is tighter — plan for longer hold periods and verify local employment stability. Local rents consume roughly 20% of household income — a useful sanity check on tenant affordability.

That score is driven by a population of 12,867, median household income of $117,364/year and median weekly rent of $450. 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 main demand drivers in Gladesville are proximity to Sydney (9 km), an above-state-median household income of $117,364/year, a dwelling mix that is 40% separate houses, roughly 3 schools and 5 parks within the catchment. Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Gladesville has a usual resident population of approximately 12,867, compared with a New South Wales suburb median of 5,325 — placing it in the upper half of the state's suburbs by size.

The median monthly mortgage repayment in Gladesville is $2,800, or approximately $33,600/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 $450 works out to $1,950/month, covering 70% of the median mortgage repayment of $2,800/month. That leaves a $850/month shortfall (around $10,200/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 $2,800 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.
