PORTH MYNACH 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 PORTH MYNACH sales from March 2000 and May 2004 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 2000 sale was for 65% above the HPI. So the extrapolation line tracks at 65% above the HPI over time, until the May 2004 sale, where it falls to 54% above the HPI. The line then continues to track at 54% above the HPI.

What might PORTH MYNACH be worth now?

PORTH MYNACH might now be worth an estimated £465,027.

This is based on house price inflation of 100.4%, between May 2004 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 100.4% inflationary increase is applied to the most recent sale price for PORTH MYNACH of £232,000 on 6th May 2004. For the value to have increased from £232,000 to £465,027 over the 21 years and three months to February 2025, the following assumptions must hold true:

• The value of PORTH MYNACH has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The May 2004 sale price of £232,000 represented a fair market value for the property.
• The size, condition, and specification of PORTH MYNACH has not materially changed since May 2004.
