Land registry data shows two sales for 66 FAENOL ISAF since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Gwynedd local authority area for the corresponding sale date.

The below graph shows the average detached house price in the Gwynedd local authority area over time, sourced from the HPI. The two 66 FAENOL ISAF sales from June 1997 and May 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 June 1997 sale was for 97% above the HPI. So the extrapolation line tracks at 97% above the HPI over time, until the May 2019 sale, where it falls to roughly the same level as the HPI. The line then continues to track in line with the HPI.
66 FAENOL ISAF might now be worth an estimated £301,446.
This is based on house price inflation of 26.7%, between May 2019 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 26.7% inflationary increase is applied to the most recent sale price for 66 FAENOL ISAF of £238,000 on 10th May 2019. For the value to have increased from £238,000 to £301,446 over the six years and three months to February 2025, the following assumptions must hold true:
