The below graph shows the average semi-detached house price in the Conwy local authority area over time, sourced from the HPI. The three 20 GWYDYR ROAD sales between September 2000 and May 2017 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 2006 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the May 2017 sale, where it rises to 17% above the HPI. The line then continues to track at 17% above the HPI.

20 GWYDYR ROAD might now be worth an estimated £251,043.
This is based on house price inflation of 48.1%, between May 2017 and July 2025, for semi-detached houses, in the Conwy local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 48.1% inflationary increase is applied to the most recent sale price for 20 GWYDYR ROAD of £169,500 on 12th May 2017. For the value to have increased from £169,500 to £251,043 over the seven years and ten months to July 2025, the following assumptions must hold true:
