PENTREGOF 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 PENTREGOF sales from April 2000 and March 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 April 2000 sale was for 20% above the HPI. So the extrapolation line tracks at 20% above the HPI over time, until the March 2016 sale, where it rises to 34% above the HPI. The line then continues to track at 34% above the HPI.

What might PENTREGOF be worth now?

PENTREGOF might now be worth an estimated £421,137.

This is based on house price inflation of 42.8%, between March 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 42.8% inflationary increase is applied to the most recent sale price for PENTREGOF of £295,000 on 31st March 2016. For the value to have increased from £295,000 to £421,137 over the nine years and one month to February 2025, the following assumptions must hold true:

• The value of PENTREGOF has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The March 2016 sale price of £295,000 represented a fair market value for the property.
• The size, condition, and specification of PENTREGOF has not materially changed since March 2016.
