18 LLYS TREGARNEDD 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 18 LLYS TREGARNEDD sales from March 2008 and November 2020 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 March 2008 sale was for 4% above the HPI. So the extrapolation line tracks at 4% above the HPI over time, until the November 2020 sale, where it falls to 6% below the HPI. The line then continues to track at 6% below the HPI.

What might 18 LLYS TREGARNEDD be worth now?

This is based on house price inflation of 16.7%, between November 2020 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).
