20 CLOS Y GELLI 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 GELLI sales from May 1998 and October 2021 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 May 1998 sale was for 38% below the HPI. So the extrapolation line tracks at 38% below the HPI over time, until the October 2021 sale, where it falls to 49% below the HPI. The line then continues to track at 49% below the HPI.
