The below graph shows the average detached house price in the Denbighshire local authority area over time, sourced from the HPI. The three TONGLAS sales between November 2012 and October 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 January 2017 sale was for 73% above the HPI. So the extrapolation line tracks at 73% above the HPI over time, until the October 2024 sale, where it falls to 41% above the HPI. The line then continues to track at 41% above the HPI.
TONGLAS might now be worth an estimated £352,612.
This is based on house price deflation of 6%, between October 2024 and December 2024, for detached houses, in the Denbighshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 6% deflationary decrease is applied to the most recent sale price for TONGLAS of £375,000 on 28th October 2024. For the value to have decreased from £375,000 to £352,612 over the ten months to December 2024, the following assumptions must hold true:
