A large development pipeline in Mosman does not automatically mean falling prices. Supply additions are most disruptive when they are concentrated in one property type (typically apartments) and coincide with softer underlying demand. If the pipeline is dominated by townhouses or terraces aimed at owner-occupiers, the supply impact on investor yields is likely to be modest. Check the dwelling-type breakdown in the card to assess the risk for your specific purchase type.
