7 TREM Y CASTELL Price Paid vs. HPI Average

The below graph shows the average detached house price in the Caerphilly local authority area over time, sourced from the HPI. The two 7 TREM Y CASTELL sales from September 1996 and August 2017 have been plotted on the graph.

For example, the September 1996 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the August 2017 sale, where it falls to 14% above the HPI.
