| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|

The below graph shows the average terraced house price in the Powys local authority area over time, sourced from the HPI. The three 11A CASTLE ROAD sales between April 2004 and December 2015 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 2005 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the December 2015 sale, where it falls to 8% below the HPI. The line then continues to track at 8% below the HPI.

11A CASTLE ROAD might now be worth an estimated £152,336.
This is based on house price inflation of 45.1%, between December 2015 and July 2025, for terraced 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 45.1% inflationary increase is applied to the most recent sale price for 11A CASTLE ROAD of £105,000 on 21st December 2015. For the value to have increased from £105,000 to £152,336 over the ten years and five months to July 2025, the following assumptions must hold true:
