Land registry data shows two sales for 50 CASTLE ROAD since 1st January 1995. The below table shows the price paid for the two sales, along with the average terraced price in the Powys local authority area for the corresponding sale date.

The average price is sourced from the Office for National Statistics' House Price Index (HPI).

The below graph shows the average terraced house price in the Powys local authority area over time, sourced from the HPI. The two 50 CASTLE ROAD sales from April 1995 and June 2025 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 April 1995 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the June 2025 sale, where it falls to 10% below the HPI. The line then continues to track at 10% below the HPI.

50 CASTLE ROAD might now be worth an estimated £148,729.
This is based on house price inflation of 2.6%, between June 2025 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 2.6% inflationary increase is applied to the most recent sale price for 50 CASTLE ROAD of £145,000 on 30th June 2025. For the value to have increased from £145,000 to £148,729 over the eleven months to July 2025, the following assumptions must hold true:
