4 LON TESOG 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 4 LON TESOG sales from July 2006 and October 2010 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 2006 sale was for 26% above the HPI. So the extrapolation line tracks at 26% above the HPI over time, until the October 2010 sale, where it falls to 17% above the HPI. The line then continues to track at 17% above the HPI.

What might 4 LON TESOG be worth now?

This is based on house price inflation of 44.8%, between October 2010 and December 2024, 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 44.8% inflationary increase is applied to the most recent sale price for 4 LON TESOG of £245,000 on 20th October 2010. For the value to have increased from £245,000 to £354,662 over the thirteen years and ten months to December 2024, the following assumptions must hold true:
