1 DOL Y DDERWEN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Powys local authority area over time, sourced from the HPI. The three 1 DOL Y DDERWEN sales between June 2002 and August 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 June 2008 sale was for 44% below the HPI. So the extrapolation line tracks at 44% below the HPI over time, until the August 2016 sale, which was also at 44% below the HPI.

What might 1 DOL Y DDERWEN be worth now?

This is based on house price inflation of 43.9%, between August 2016 and February 2025, for detached houses, in the Powys local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 43.9% inflationary increase is applied to the most recent sale price for 1 DOL Y DDERWEN of £125,000 on 19th August 2016. For the value to have increased from £125,000 to £179,876 over the nine years and six months to February 2025, the following assumptions must hold true:
