15 TREM Y CASTELL Price Paid vs. HPI Average

The below graph shows the average detached house price in the Conwy local authority area over time, sourced from the HPI. The two 15 TREM Y CASTELL sales from January 2011 and January 2016 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 January 2011 sale was for 39% below the HPI. So the extrapolation line tracks at 39% below the HPI over time, until the January 2016 sale, where it rises to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 15 TREM Y CASTELL be worth now?

This is based on house price inflation of 49%, between January 2016 and December 2024, for detached houses, in the Conwy local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 49% inflationary increase is applied to the most recent sale price for 15 TREM Y CASTELL of £152,500 on 21st January 2016. For the value to have increased from £152,500 to £227,236 over the seven years and one month to December 2024, the following assumptions must hold true:
