3 LON TRAETH 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 3 LON TRAETH sales from October 2013 and March 2017 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 2013 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the March 2017 sale, where it rises to 5% above the HPI. The line then continues to track at 5% above the HPI.

What might 3 LON TRAETH be worth now?

3 LON TRAETH might now be worth an estimated £330,566.

This is based on house price inflation of 41.6%, between March 2017 and October 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 41.6% inflationary increase is applied to the most recent sale price for 3 LON TRAETH of £233,500 on 31st March 2017. For the value to have increased from £233,500 to £330,566 over the seven years and five months to October 2025, the following assumptions must hold true:

  • The value of 3 LON TRAETH has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
  • The March 2017 sale price of £233,500 represented a fair market value for the property.
  • The size, condition, and specification of 3 LON TRAETH has not materially changed since March 2017.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
