15 TREM NANT EIRIAS 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 15 TREM NANT EIRIAS sales between August 2003 and March 2023 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 August 2019 sale was for 38% above the HPI. So the extrapolation line tracks at 38% above the HPI over time, until the March 2023 sale, where it rises to 48% above the HPI. The line then continues to track at 48% above the HPI.

What might 15 TREM NANT EIRIAS be worth now?

This is based on house price inflation of 0.2%, between March 2023 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 0.2% inflationary increase is applied to the most recent sale price for 15 TREM NANT EIRIAS of £450,000 on 17th March 2023. For the value to have increased from £450,000 to £450,844 over the two years and one month to February 2025, the following assumptions must hold true:
