Development
Residential development activity is lower than average in Killarney Vale according to AreaSearch's national comparison of local real estate markets
Based on AreaSearch analysis, Killarney Vale recorded approximately 32 residential property approvals per year. Between FY-21 and FY-25, around 164 homes were approved, with an additional 10 approved in FY-26. On average, 0.2 new residents per year per dwelling were added over the past five financial years.
This indicates that supply is keeping pace with or exceeding demand, offering ample buyer choice and capacity for population growth beyond current forecasts. The average construction value of these properties was $323,000, which is under regional levels, suggesting more accessible housing choices for buyers. In FY-26, $16.3 million in commercial approvals have been registered, indicating steady commercial investment activity.
Compared to Greater Sydney, Killarney Vale has similar development levels per person, maintaining market balance with the broader area. Recent construction comprises 81.0% detached dwellings and 19.0% medium and high-density housing, preserving the area's traditional suburban character focused on family homes. The location has approximately 251 people per dwelling approval, indicating a low density market. According to AreaSearch's latest quarterly estimate, Killarney Vale is projected to gain 114 residents by 2041. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling population growth that exceeds current forecasts.
