The property market in CM20 3JG is characterised by a 51% home ownership rate, indicating a mix of owner-occupied and rental properties. The area’s accommodation type is primarily houses, reflecting a suburban layout typical of post-war New Town developments. This suggests a focus on family homes with gardens, which may appeal to buyers seeking space and privacy. The small residential cluster means the housing stock is likely limited in scale, with limited scope for new builds given the area’s historical designation as a conservation zone.

However, the relatively low home ownership rate also implies a significant rental market, which could affect property availability and competition for purchase.
