12 LON Y BRYN 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 three 12 LON Y BRYN sales between September 1997 and June 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 September 2002 sale was for 70% above the HPI. So the extrapolation line tracks at 70% above the HPI over time, until the June 2017 sale, where it falls to 28% above the HPI. The line then continues to track at 28% above the HPI.

What might 12 LON Y BRYN be worth now?

12 LON Y BRYN might now be worth an estimated £254,270.

This is based on house price inflation of 37.1%, between June 2017 and December 2024, 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 37.1% inflationary increase is applied to the most recent sale price for 12 LON Y BRYN of £185,500 on 30th June 2017. For the value to have increased from £185,500 to £254,270 over the six years and six months to December 2024, the following assumptions must hold true:

• The value of 12 LON Y BRYN has moved in line with the HPI for semi-detached houses in the Gwynedd local authority area.
• The June 2017 sale price of £185,500 represented a fair market value for the property.
