16 COED Y CASTELL 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 16 COED Y CASTELL sales from October 2019 and November 2021 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 2019 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the November 2021 sale, where it rises to 2% above the HPI. The line then continues to track at 2% above the HPI.

What might 16 COED Y CASTELL be worth now?

This is based on house price inflation of 4.5%, between November 2021 and December 2024, 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 4.5% inflationary increase is applied to the most recent sale price for 16 COED Y CASTELL of £290,000 on 5th November 2021. For the value to have increased from £290,000 to £302,980 over the two years and eleven months to December 2024, the following assumptions must hold true:

• The value of 16 COED Y CASTELL has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The November 2021 sale price of £290,000 represented a fair market value for the property.
