GWERN EITHIN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Isle of Anglesey local authority area over time, sourced from the HPI. The two GWERN EITHIN sales from June 2005 and November 2013 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 June 2005 sale was for 50% above the HPI. So the extrapolation line tracks at 50% above the HPI over time, until the November 2013 sale, where it falls to 31% above the HPI. The line then continues to track at 31% above the HPI.

What might GWERN EITHIN be worth now?

GWERN EITHIN might now be worth an estimated £410,312.

This is based on house price inflation of 64.1%, between November 2013 and October 2025, for detached houses, in the Isle of Anglesey local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 64.1% inflationary increase is applied to the most recent sale price for GWERN EITHIN of £250,000 on 27th November 2013. For the value to have increased from £250,000 to £410,312 over the twelve years and one month to October 2025, the following assumptions must hold true:

• The value of GWERN EITHIN has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The November 2013 sale price of £250,000 represented a fair market value for the property.
• The size, condition, and specification of GWERN EITHIN has not materially changed since November 2013.
