16 TANLLWYFAN 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 four 16 TANLLWYFAN sales between April 2003 and November 2024 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 November 2021 sale was for 73% above the HPI. So the extrapolation line tracks at 73% above the HPI over time, until the November 2024 sale, where it rises to 92% above the HPI. The line then continues to track at 92% above the HPI.

This is based on house price deflation of 1%, between November 2024 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 1% deflationary decrease is applied to the most recent sale price for 16 TANLLWYFAN of £590,000 on 20th November 2024. For the value to have decreased from £590,000 to £584,311 over the one year and nine months to February 2025, the following assumptions must hold true:
