3 GWEL Y MYNYDD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Gwynedd local authority area over time, sourced from the HPI. The two 3 GWEL Y MYNYDD sales from October 2001 and January 2003 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 2001 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the January 2003 sale, where it falls to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might 3 GWEL Y MYNYDD be worth now?

This is based on house price inflation of 162.2%, between January 2003 and February 2025, for detached houses, in the Gwynedd local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 162.2% inflationary increase is applied to the most recent sale price for 3 GWEL Y MYNYDD of £124,250 on 31st January 2003. For the value to have increased from £124,250 to £325,761 over the 21 years and eleven months to February 2025, the following assumptions must hold true:
