20 DUNGANNON CHASE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Southend-on-Sea local authority area over time, sourced from the HPI. The two 20 DUNGANNON CHASE sales from October 2014 and March 2025 have been plotted on the graph.

For example, the October 2014 sale was for 45% above the HPI. So the extrapolation line tracks at 45% above the HPI over time, until the March 2025 sale, where it rises to 57% above the HPI. The line then continues to track at 57% above the HPI.
