Seven Hills

Detached houses still define Seven Hills: 84.2% of dwellings are separate homes, yet 36.2% of households rent and 46.3% of residents were born overseas. The $1,135,000 median house price sits alongside household income in the 70.6 percentile, above average, which helps explain steady mortgage demand. Compared with neighbouring Blacktown and Lalor Park, Seven Hills sits in the middle: large enough for 20,095 residents and 9 schools, but still strongly house-based.

For homebuyers, Seven Hills favours house seekers: 84.2% of dwellings are separate houses, 9.9% are semi-detached and only 5.6% are apartments, giving more land choice than unit-led suburbs. The median house price is $1,135,000, with the quarterly series up 7.3% from $1,085,500 in 2024 to $1,165,000 in 2025. Mortgage costs take 26.9% of income and matter because 35.5% of households are mortgaged, while 50.2% of homes have 3 bedrooms.

For Buyers

For homebuyers, Seven Hills favours house seekers: 84.2% of dwellings are separate houses, 9.9% are semi-detached and only 5.6% are apartments, giving more land choice than unit-led suburbs. The median house price is $1,135,000, with the quarterly series up 7.3% from $1,085,500 in 2024 to $1,165,000 in 2025. Mortgage costs take 26.9% of income and matter because 35.5% of households are mortgaged, while 50.2% of homes have 3 bedrooms.

For Investors

Investors get a mixed signal: 36.2% of households rent, higher than the 28.3% owned outright share, so tenant depth is real. Weekly rent is $400, but vacancy at 5.5% means leasing power may be weaker than in tighter markets. Price momentum is stronger, with the series rising 7.3% to $1,165,000 in 2025. The 215 development applications in 12 months also point to renewal, because dual occupancy and house projects can add stock in a detached-dominant suburb.

Housing remains broad-lot by form, but tenure is balanced. Separate houses make up 84.2% of dwellings, far higher than apartments at 5.6%, while 28.3% are owned outright, 35.5% mortgaged and 36.2% rented. The house median is $1,135,000, roughly 11.5 times the $1,892 weekly household income annualised. Prices rose 7.3% from $1,085,500 in 2024 to $1,165,000 in 2025, with the latest quarter also the peak, because 3-bedroom stock at 50.2% remains the core family product.

How to read these comparisons

Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.

Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.

Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
