31 MAES Y DDERWEN 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 31 MAES Y DDERWEN sales from October 1998 and February 2004 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 October 1998 sale was for 13% above the HPI. So the extrapolation line tracks at 13% above the HPI over time, until the February 2004 sale, where it rises to 31% above the HPI. The line then continues to track at 31% above the HPI.

The 123.1% inflationary increase is applied to the most recent sale price for 31 MAES Y DDERWEN of £167,500 on 4th February 2004. For the value to have increased from £167,500 to £373,700 over the twenty years and seven months to July 2025, the following assumptions must hold true:
