12 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 12 TREM Y CASTELL sales from May 1999 and July 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 May 1999 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the July 2016 sale, where it falls to 34% below the HPI. The line then continues to track at 34% below the HPI.

What might 12 TREM Y CASTELL be worth now?

This is based on house price inflation of 48.7%, between July 2016 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 48.7% inflationary increase is applied to the most recent sale price for 12 TREM Y CASTELL of £135,000 on 28th July 2016. For the value to have increased from £135,000 to £200,769 over the nine years and five months to February 2025, the following assumptions must hold true:
