20 CLOS Y DERI Price Paid vs. HPI Average

The below graph shows the average detached house price in the Carmarthenshire local authority area over time, sourced from the HPI. The two 20 CLOS Y DERI sales from November 1996 and July 2014 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 November 1996 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the July 2014 sale, where it falls to 29% below the HPI. The line then continues to track at 29% below the HPI.
