10 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 three 10 TREM Y CASTELL sales between January 2001 and July 2011 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 2004 sale was for 4% above the HPI. So the extrapolation line tracks at 4% above the HPI over time, until the July 2011 sale, where it falls to 24% below the HPI. The line then continues to track at 24% below the HPI.

What might 10 TREM Y CASTELL be worth now?

This is based on house price inflation of 59.2%, between July 2011 and February 2025, 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 59.2% inflationary increase is applied to the most recent sale price for 10 TREM Y CASTELL of £145,000 on 11th July 2011. For the value to have increased from £145,000 to £230,815 over the fourteen years and five months to February 2025, the following assumptions must hold true:
