8 BLACK ROCK ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The two 8 BLACK ROCK ROAD sales from June 1998 and December 2023 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 1998 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the December 2023 sale, where it rises to 7% above the HPI. The line then continues to track at 7% above the HPI.

What might 8 BLACK ROCK ROAD be worth now?

8 BLACK ROCK ROAD might now be worth an estimated £525,759.

This is based on house price inflation of 2.1%, between December 2023 and February 2025, for detached houses, in the Monmouthshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.1% inflationary increase is applied to the most recent sale price for 8 BLACK ROCK ROAD of £515,000 on 18th December 2023. For the value to have increased from £515,000 to £525,759 over the two years and ten months to February 2025, the following assumptions must hold true:

• The value of 8 BLACK ROCK ROAD has moved in line with the HPI for detached houses in the Monmouthshire local authority area.
