12 Y BRYN 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 12 Y BRYN sales from March 2009 and June 2010 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 March 2009 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the June 2010 sale, where it rises to roughly the same level as the HPI. The line then continues to track in line with the HPI.

What might 12 Y BRYN be worth now?

12 Y BRYN might now be worth an estimated £300,699.

This is based on house price inflation of 52.3%, between June 2010 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 52.3% inflationary increase is applied to the most recent sale price for 12 Y BRYN of £197,500 on 21st June 2010. For the value to have increased from £197,500 to £300,699 over the fifteen years and four months to February 2025, the following assumptions must hold true:

• The value of 12 Y BRYN has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The June 2010 sale price of £197,500 represented a fair market value for the property.
• The size, condition, and specification of 12 Y BRYN has not materially changed since June 2010.
