The below graph shows the average detached house price in the Gwynedd local authority area over time, sourced from the HPI. The four 15 HEOL SEITHENDRE sales between May 1999 and November 2018 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 July 2006 sale was for 26% below the HPI. So the extrapolation line tracks at 26% below the HPI over time, until the November 2018 sale, where it falls to 45% below the HPI. The line then continues to track at 45% below the HPI.
15 HEOL SEITHENDRE might now be worth an estimated £166,127.
This is based on house price inflation of 28.3%, between November 2018 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 28.3% inflationary increase is applied to the most recent sale price for 15 HEOL SEITHENDRE of £129,500 on 30th November 2018. For the value to have increased from £129,500 to £166,127 over the seven years and nine months to February 2025, the following assumptions must hold true:
