PEN YR ARGAU 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 PEN YR ARGAU sales from October 2005 and July 2007 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 2005 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the July 2007 sale, where it rises to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might PEN YR ARGAU be worth now?

PEN YR ARGAU might now be worth an estimated £354,664.

This is based on house price inflation of 50.9%, between July 2007 and February 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 50.9% inflationary increase is applied to the most recent sale price for PEN YR ARGAU of £235,000 on 13th July 2007. For the value to have increased from £235,000 to £354,664 over the eighteen years and five months to February 2025, the following assumptions must hold true:

• The value of PEN YR ARGAU has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The July 2007 sale price of £235,000 represented a fair market value for the property.
• The size, condition, and specification of PEN YR ARGAU has not materially changed since July 2007.
