The below graph shows the average semi-detached house price in the Gwynedd local authority area over time, sourced from the HPI. The two 123 GWEL Y LLAN sales from April 2018 and November 2019 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 April 2018 sale was for 14% above the HPI. So the extrapolation line tracks at 14% above the HPI over time, until the November 2019 sale, where it falls to 8% above the HPI. The line then continues to track at 8% above the HPI.
123 GWEL Y LLAN might now be worth an estimated £218,586.
This is based on house price inflation of 26.7%, between November 2019 and July 2025, 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 26.7% inflationary increase is applied to the most recent sale price for 123 GWEL Y LLAN of £172,500 on 1st November 2019. For the value to have increased from £172,500 to £218,586 over the six years and four months to July 2025, the following assumptions must hold true:
