PENTERFYN 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 PENTERFYN sales from June 2015 and February 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 June 2015 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the February 2016 sale, where it rises to 6% above the HPI. The line then continues to track at 6% above the HPI.

What might PENTERFYN be worth now?

PENTERFYN might now be worth an estimated £334,161.

This is based on house price inflation of 44%, between February 2016 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 44% inflationary increase is applied to the most recent sale price for PENTERFYN of £232,000 on 19th February 2016. For the value to have increased from £232,000 to £334,161 over the nine years to February 2025, the following assumptions must hold true:

• The value of PENTERFYN has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The February 2016 sale price of £232,000 represented a fair market value for the property.
• The size, condition, and specification of PENTERFYN has not materially changed since February 2016.
