TREWYNYON Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cornwall local authority area over time, sourced from the HPI. The three TREWYNYON sales between July 1996 and December 2018 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the March 2004 sale was for 8% above the HPI. So the extrapolation line tracks at 8% above the HPI over time, until the December 2018 sale, where it rises to 10% above the HPI. The line then continues to track at 10% above the HPI.
