21 Y GLYN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Gwynedd local authority area over time, sourced from the HPI. The two 21 Y GLYN sales from October 2004 and August 2009 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 2004 sale was for 73% below the HPI. So the extrapolation line tracks at 73% below the HPI over time, until the August 2009 sale, where it rises to 9% below the HPI. The line then continues to track at 9% below the HPI.

What might 21 Y GLYN be worth now?

21 Y GLYN might now be worth an estimated £187,820.

This is based on house price inflation of 53.3%, between August 2009 and June 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 53.3% inflationary increase is applied to the most recent sale price for 21 Y GLYN of £122,500 on 21st August 2009. For the value to have increased from £122,500 to £187,820 over the sixteen years and two months to June 2025, the following assumptions must hold true:

• The value of 21 Y GLYN has moved in line with the HPI for semi-detached houses in the Gwynedd local authority area.
• The August 2009 sale price of £122,500 represented a fair market value for the property.
