6 PLAS IOAN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Carmarthenshire local authority area over time, sourced from the HPI. The three 6 PLAS IOAN sales between July 1998 and February 2025 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 2016 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the February 2025 sale, where it falls to 7% below the HPI. The line then continues to track at 7% below the HPI.
