NSW 2147 Census 2021 + Live DA Data

Kings Langley

Household incomes at the 91.8th percentile ($2,457/week) combined with a 48.1% mortgage rate and 94.0% detached housing make Kings Langley one of western Sydney's most committed mortgage-belt suburbs. The $1,530,000 median grew just 2.3% from $1,510,000 in 2024 to $1,545,000 in 2025, suggesting the market has reached a price ceiling relative to incomes. Only 12.8% rent, the lowest renter share in this batch, and the 85.9% stability rate means residents rarely leave. Net internal migration runs at negative 293 per year, offset by 276 overseas arrivals, creating a population replacement dynamic where domestic families depart while overseas households arrive.

The $1,530,000 median buys a detached house (94.0% of stock) in a suburb where 62.3% of homes have four or more bedrooms and 33.2% have three bedrooms. Prices grew modestly at 2.3% from $1,510,000 in 2024 to $1,545,000 in 2025. Monthly mortgage repayments of $2,579 produce a mortgage-to-income ratio of 24.2%, well below the stress threshold. The 39.2% outright ownership rate is high, and the 85.9% stability rate means neighbours stay long-term. Walking/cycling at 1.5% and public transport at 3.4% are very low, making this a fully car-dependent suburb at 89.3%. Vacancy at 3.6% is tight, reflecting strong demand.

For Buyers

The $1,530,000 median buys a detached house (94.0% of stock) in a suburb where 62.3% of homes have four or more bedrooms and 33.2% have three bedrooms. Prices grew modestly at 2.3% from $1,510,000 in 2024 to $1,545,000 in 2025. Monthly mortgage repayments of $2,579 produce a mortgage-to-income ratio of 24.2%, well below the stress threshold. The 39.2% outright ownership rate is high, and the 85.9% stability rate means neighbours stay long-term. Walking/cycling at 1.5% and public transport at 3.4% are very low, making this a fully car-dependent suburb at 89.3%. Vacancy at 3.6% is tight, reflecting strong demand.

For Investors

The 12.8% renter share is very low, severely limiting the tenant pool. Median weekly rent of $500 against a $1,530,000 median gives a gross yield of roughly 1.7%, among the lowest in this dataset. Vacancy at 3.6% is tight, meaning the few rental properties are in demand. With 67 DAs in 12 months, development activity is moderate. Net overseas migration of 276 per year provides demand, but internal outflow of 293 per year means domestic families are leaving, likely due to affordability pressure. The 14.1% turnover is very low, consistent with owner-occupied dominance. This is a capital growth suburb, not a yield market.

Outright ownership at 39.2% and mortgage holders at 48.1% together account for 87.3% of tenure, leaving just 12.8% renting, the lowest rental share in this batch. Detached houses at 94.0% dominate almost completely, with semi-detached at 4.6% and apartments at 1.3%. Four-plus bedroom homes at 62.3% are the clear majority. The median edged from $1,510,000 in 2024 to $1,545,000 in 2025, a 2.3% gain. At household income of $2,457/week, the price-to-income ratio is approximately 12.0x annual income, elevated but the 39.2% outright ownership rate indicates many holders purchased at much lower historical prices.

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.
