Grantham Farm
A 30-year median age, 43.3% overseas-born share and 99.7% detached-home rate give Grantham Farm a young, family-oriented profile, while household income sits at the 93.1st percentile nationally. Its 3,669 residents occupy just 3.62 sq km at 1,014 people per sq km, creating a more concentrated urban form than a rural fringe. The 62.4% mortgage share points to a strong owner-occupier pipeline, supported by 61.9% of families being couples with children. For buyers comparing Grantham Farm with nearby Riverstone or Schofields, the suburb stands out as 10 years younger than the national comparison, with university participation 19.6 percentage points higher.

Grantham Farm suits buyers seeking detached family space, because 99.7% of dwellings are separate houses and 85.5% have four or more bedrooms. The trade-off is loan exposure: 62.4% of households hold a mortgage, compared with only 6.5% owning outright, while the monthly mortgage figure is $2,700. Mortgage costs equal 24.3% of household income, higher than the 21.0% rent-to-income ratio, and the mortgage stress flag is false. Weekly rent is $540 for households that are not ready to buy. Income at the 93.1st percentile nationally is above average and may support borrowing capacity, subject to lender tests. Compared with apartment-led areas, Grantham Farm has fewer compact entry points.

Compared with apartment-led areas, Grantham Farm has fewer compact entry points.
For Investors
Rental demand has a solid base because 30.9% of households rent, the weekly rent is $540 and vacancy is 2.9%. That combination can support leasing activity, although the detached-house format means investors are targeting family tenants rather than a broad apartment market. Development activity is high at 116 applications in 12 months, which may increase future competition for tenants while confirming ongoing housing turnover. The forecast points to 1.0% annual growth with Balanced migration, so the case is more about steady occupancy and long-run participation than a rapid-growth thesis. Household income ranks at the 93.1st percentile nationally, above average, which may support tenant payment capacity. Compare actual sales, costs and net yield before relying on the rent figure.

Tenure
Detached family housing dominates: 99.7% of dwellings are separate houses, 85.5% contain four or more bedrooms and only 0.3% are apartments. Tenure is tilted toward leveraged ownership, with 62.4% paying a mortgage, 30.9% renting and 6.5% owning outright. That pattern fits the average 3.2-person household and 61.9% share of couples with children, because larger homes are being used by family households. Mortgage repayments equal 24.3% of household income, higher than the 21.0% rent-to-income ratio, while vacancy is 2.9%, leaving limited rental slack if demand rises. Compared with compact apartment markets, Grantham Farm offers less housing variety. Compared with nearby Riverstone and Schofields, buyers should check individual estates for lot size, dwelling age and resale differences.

Transport to Work
Daily life is structured around cars and home-based work: 46.0% drive to work, 47.7% work from home, 3.5% use public transport and 0.4% walk or cycle. The work-from-home share is higher than public transport use, which may reduce weekday commuting but makes local services and road access important. Grantham Farm covers 3.62 sq km and has 3,669 residents, a density of 1,014 people per sq km, so amenities need to serve a concentrated population rather than a widely scattered one. Families should check exact-address enrolment zones and nearby school options before signing a lease or contract. The IRSAD decile is 4, below the household income percentile of 93.1, showing that livability and affordability can vary between households. Compare current local safety information for the exact address before deciding.

Population Forecast
+1.0%/yr
(+65 people/yr)
EstablishedGrowth is steady rather than explosive, with the forecast trend at 1.0% annually and migration labelled Balanced. Across the wider area, population change over 10 years is 13.8%, while the shift trajectory is Aging, linked to a 7.2 percentage-point rise in the senior share and a 3.7-point fall in the young share. The main gentrification measure gives a score of 6 and stage Not gentrifying, so the direction is better read as gradual maturation than a clear redevelopment wave. Affordability moved from 27.0% in 2011 to 25.3% in 2021 and is labelled Stable, which helps explain why mortgage-led family demand can persist. Compared with a high-growth speculative market, the outlook is more measured and driven by balanced migration rather than a single inflow source.

What schools are in Grantham Farm?

Growth is forecast at 1.0% annually with Balanced migration, so compare net yield, holding costs and future competition rather than assuming rapid price growth.

The suburb has 3,669 residents today. Across the wider area, population change is 13.8% over 10 years, with annual growth forecast at 1.0% and migration described as Balanced.

Yes, activity is high: 116 development applications were recorded in 12 months, which is higher than a static pipeline. Recent examples include a swimming pool and a 1-dwelling residential accommodation application. Treat the volume as evidence of ongoing building activity, not a guaranteed number of new homes, because dwelling counts are not available for every application.
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 education open registers (school locations), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
