20 TAN Y WAUN 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 two 20 TAN Y WAUN sales from March 1996 and May 2008 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 March 1996 sale was for 75% below the HPI. So the extrapolation line tracks at 75% below the HPI over time, until the May 2008 sale, where it rises to 6% above the HPI. The line then continues to track at 6% above the HPI.

What might 20 TAN Y WAUN be worth now?

This is based on house price inflation of 56.4%, between May 2008 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 56.4% inflationary increase is applied to the most recent sale price for 20 TAN Y WAUN of £220,000 on 16th May 2008. For the value to have increased from £220,000 to £344,063 over the seventeen years and three months to February 2025, the following assumptions must hold true:

• The value of 20 TAN Y WAUN has moved in line with the HPI for detached houses in the Powys local authority area.
• The May 2008 sale price of £220,000 represented a fair market value for the property.
