TREFNANT BACH 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 TREFNANT BACH sales from July 2009 and October 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 July 2009 sale was for 66% above the HPI. So the extrapolation line tracks at 66% above the HPI over time, until the October 2013 sale, where it rises to 84% above the HPI. The line then continues to track at 84% above the HPI.

What might TREFNANT BACH be worth now?

TREFNANT BACH might now be worth an estimated £580,860.

This is based on house price inflation of 63.6%, between October 2013 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 63.6% inflationary increase is applied to the most recent sale price for TREFNANT BACH of £355,000 on 17th October 2013. For the value to have increased from £355,000 to £580,860 over the twelve years and eight months to February 2025, the following assumptions must hold true:

• The value of TREFNANT BACH has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
• The October 2013 sale price of £355,000 represented a fair market value for the property.
• The size, condition, and specification of TREFNANT BACH has not materially changed since October 2013.
