BORTHWEN 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 BORTHWEN sales from April 2010 and August 2015 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 2010 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the August 2015 sale, where it rises to 1% above the HPI. The line then continues to track at 1% above the HPI.

What might BORTHWEN be worth now?

BORTHWEN might now be worth an estimated £318,410.

This is based on house price inflation of 51.6%, between August 2015 and March 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 51.6% inflationary increase is applied to the most recent sale price for BORTHWEN of £210,000 on 24th August 2015. For the value to have increased from £210,000 to £318,410 over the ten years and five months to March 2025, the following assumptions must hold true:

• The value of BORTHWEN has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The August 2015 sale price of £210,000 represented a fair market value for the property.
• The size, condition, and specification of BORTHWEN has not materially changed since August 2015.
