9 MAES GERDDI 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 9 MAES GERDDI sales from October 2001 and November 2016 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 2001 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the November 2016 sale, where it rises to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 9 MAES GERDDI be worth now?

9 MAES GERDDI might now be worth an estimated £222,073.

This is based on house price inflation of 34.6%, between November 2016 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 34.6% inflationary increase is applied to the most recent sale price for 9 MAES GERDDI of £165,000 on 18th November 2016. For the value to have increased from £165,000 to £222,073 over the seven years and eleven months to December 2024, the following assumptions must hold true:

• The value of 9 MAES GERDDI has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The November 2016 sale price of £165,000 represented a fair market value for the property.
• The size, condition, and specification of 9 MAES GERDDI has not materially changed since November 2016.
