The median house price of $955,000 sits above the national median, reflecting western Sydney's sustained demand. Price history shows movement from $925,000 in 2024 to $1,022,500 in 2025, a 10.5% rise over one year, suggesting strong recent appreciation. The stock is overwhelmingly separate houses at 94.9%, with apartments at just 1.4%, so buyers face limited dwelling-type diversity. The three-bedroom configuration dominates at 64.5% of dwellings, with 4-plus bedroom homes at 27.9%, indicating family-scale supply. Monthly mortgage repayments average $2,102, and the mortgage-to-income ratio of 26.3% stays below the 30% stress threshold, meaning the suburb is more affordable relative to household income than many comparable Sydney markets. Outright owners account for 26.3% of households, lower than typical for a suburban area, with 43.8% carrying a mortgage.

For Investors
Dean Park's renter share of 29.9% and weekly rent of $400 define a mid-tier rental market, with the gross yield on a $955,000 median sitting around 2.2%, modest but ahead of premium inner-city benchmarks. The vacancy rate of 4.1% sits above comfortable investment thresholds, signalling some softness in rental demand relative to supply. Development activity recorded 22 applications in the past 12 months, including secondary dwelling approvals that point to granny flat activity as an investor strategy. The migration picture is mixed: overseas arrivals add a net 97 residents per year, but internal migration removes 187, leaving a modest net decline. With 94.9% separate houses and 0.0% annual population growth, capital growth rather than rental yield is the primary investment lever.

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.
