1 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 three 1 GWEL Y MYNYDD sales between September 2001 and June 2006 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 February 2005 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the June 2006 sale, where it rises to 13% below the HPI. The line then continues to track at 13% below the HPI.

What might 1 GWEL Y MYNYDD be worth now?

This is based on house price inflation of 49.7%, between June 2006 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 49.7% inflationary increase is applied to the most recent sale price for 1 GWEL Y MYNYDD of £176,000 on 28th June 2006. For the value to have increased from £176,000 to £263,535 over the nineteen years and four months to February 2025, the following assumptions must hold true:
