SWN Y DON Price Paid vs. HPI Average

The below graph shows the average detached house price in the Gwynedd local authority area over time, sourced from the HPI. The two SWN Y DON sales from June 2001 and January 2013 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 2001 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the January 2013 sale, where it rises to 22% above the HPI. The line then continues to track at 22% above the HPI.

What might SWN Y DON be worth now?

SWN Y DON might now be worth an estimated £367,050.

This is based on house price inflation of 54.7%, between January 2013 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 54.7% inflationary increase is applied to the most recent sale price for SWN Y DON of £237,250 on 11th January 2013. For the value to have increased from £237,250 to £367,050 over the eleven years and eleven months to February 2025, the following assumptions must hold true:

• The value of SWN Y DON has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The January 2013 sale price of £237,250 represented a fair market value for the property.
• The size, condition, and specification of SWN Y DON has not materially changed since January 2013.
