With 16,379 residents, Waterloo is one of New South Wales's more populous suburbs — roughly 3.1× 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. Households here earn $105,456/year on average — 8% above the NSW suburb median of $97,552 — a modest premium that supports resilient owner-occupier demand. Median weekly rent of $530 equates to $2,297/month — about 92% of the median mortgage repayment of $2,500/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. At 3 km from the Sydney CBD, Waterloo sits inside the high-demand inner ring — properties here compete directly with the city's employment, transport and amenity networks. Only 0% 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.
This suburb suits yield-focused investors who are comfortable with lower liquidity. Employment concentration and local population trends matter more here than in metro markets. Local rents consume roughly 26% of household income — a useful sanity check on tenant affordability.

That score is driven by a population of 16,379, median household income of $105,456/year and median weekly rent of $530. 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 Waterloo are proximity to Sydney (3 km), an above-state-median household income of $105,456/year, a dwelling mix that is 0% separate houses, roughly 4 schools and 7 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.
Waterloo has a usual resident population of approximately 16,379, compared with a New South Wales suburb median of 5,325 — placing it in the upper half of the state's suburbs by size. Population is the clearest proxy for market depth: more residents mean more transactions and typically a shorter average days-on-market on resale.
Waterloo sits 3 km straight-line from the Sydney CBD. This is inner-ring territory — pricing competes directly with established Sydney employment nodes.
The most recent census recorded a median weekly rent of $530 in Waterloo, equating to approximately $27,560/year in gross rental income (state median $430/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 Waterloo is $2,500, or approximately $30,000/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 $530 works out to $2,297/month, covering 92% of the median mortgage repayment of $2,500/month. That leaves a $203/month shortfall (around $2,436/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 $2,500 median mortgage, a unit-heavy dwelling mix (0% houses) where body-corporate costs and apartment supply affect resale, 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.
