The below graph shows the average semi-detached house price in the Gwynedd local authority area over time, sourced from the HPI. The two 21 BRYN EITHINOG sales from October 2004 and November 2022 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 2004 sale was for 21% above the HPI. So the extrapolation line tracks at 21% above the HPI over time, until the November 2022 sale, where it rises to 26% above the HPI. The line then continues to track at 26% above the HPI.

21 BRYN EITHINOG might now be worth an estimated £258,117.
This is based on house price deflation of 1.5%, between November 2022 and April 2026, for semi-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 1.5% deflationary decrease is applied to the most recent sale price for 21 BRYN EITHINOG of £262,000 on 11th November 2022. For the value to have decreased from £262,000 to £258,117 over the four years and seven months to April 2026, the following assumptions must hold true:
