Miller is a smaller community of 3,374 — about 63% of the New South Wales suburb median (5,325) — so investors should factor in the narrower buyer pool and longer average time-on-market. Miller's median household income of $42,900/year is 56% below the New South Wales suburb median ($97,552) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. Weekly rent of $201 covers just 48% of the median $1,800/month mortgage repayment, leaving a $929/month gap — investors should only pursue this suburb with a clear capital-growth thesis and sufficient external income to fund the shortfall. At 31 km from Sydney, Miller is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price. Only 61% 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 long-term investors due to steady population growth and affordable entry prices. Look for established streets close to schools and shops rather than raw new-estate land. Local rents consume roughly 24% of household income — a useful sanity check on tenant affordability.

Limited buy-and-hold upside: household incomes 56% below the NSW median ($42,900 vs $97,552) means liquidity is thin and capital growth tends to lag the wider New South Wales market over full cycles.
Weak cash flow: $201/week rent covers only 48% of the $1,800/month median mortgage — a $929/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
Only 61% of dwellings are separate houses (vs 76% NSW median) — this is a unit and townhouse market, where cosmetic flips struggle against body-corporate restrictions, thinner after-reno uplift and competing new supply.

That score is driven by a population of 3,374, median household income of $42,900/year and median weekly rent of $201. 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.

Miller has a usual resident population of approximately 3,374, compared with a New South Wales suburb median of 5,325 — placing it in the lower 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.
Miller sits 31 km straight-line from the Sydney CBD. This is an outer-metro location; local employment and infrastructure announcements tend to move prices more than CBD connectivity alone.
The most recent census recorded a median weekly rent of $201 in Miller, equating to approximately $10,452/year in gross rental income (state median $430/week).

The median monthly mortgage repayment in Miller is $1,800, or approximately $21,600/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 $201 works out to $871/month, covering 48% of the median mortgage repayment of $1,800/month. That leaves a $929/month shortfall (around $11,148/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.
The main risks are a thin buyer pool (3,374 residents), interest-rate sensitivity on the $1,800 median mortgage, below-median household incomes ($42,900 vs $97,552 state median), 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.
