12 TAN Y GAER 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 TAN Y GAER sales from October 1998 and July 2005 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 1998 sale was for 45% above the HPI. So the extrapolation line tracks at 45% above the HPI over time, until the July 2005 sale, where it rises to 125% above the HPI. The line then continues to track at 125% above the HPI.

What might 12 TAN Y GAER be worth now?

12 TAN Y GAER might now be worth an estimated £679,323.

This is based on house price inflation of 56.2%, between July 2005 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 56.2% inflationary increase is applied to the most recent sale price for 12 TAN Y GAER of £435,000 on 20th July 2005. For the value to have increased from £435,000 to £679,323 over the twenty years and five months to February 2025, the following assumptions must hold true:

• The value of 12 TAN Y GAER has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The July 2005 sale price of £435,000 represented a fair market value for the property.
• The size, condition, and specification of 12 TAN Y GAER has not materially changed since July 2005.
