31 ROCKFIELD GROVE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The four 31 ROCKFIELD GROVE sales between August 1997 and April 2007 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 May 2004 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the April 2007 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.

What might 31 ROCKFIELD GROVE be worth now?

31 ROCKFIELD GROVE might now be worth an estimated £281,718.

This is based on house price inflation of 76.1%, between April 2007 and June 2025, for semi-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 76.1% inflationary increase is applied to the most recent sale price for 31 ROCKFIELD GROVE of £159,995 on 13th April 2007. For the value to have increased from £159,995 to £281,718 over the seventeen years and ten months to June 2025, the following assumptions must hold true:

• The value of 31 ROCKFIELD GROVE has moved in line with the HPI for semi-detached houses in the Monmouthshire local authority area.
• The April 2007 sale price of £159,995 represented a fair market value for the property.
