GRAIG HOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The two GRAIG HOUSE sales from September 1999 and November 2021 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 September 1999 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the November 2021 sale, where it falls to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might GRAIG HOUSE be worth now?

GRAIG HOUSE might now be worth an estimated £584,691.

This is based on house price inflation of 10.3%, between November 2021 and February 2025, for detached houses, in the Vale of Glamorgan local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 10.3% inflationary increase is applied to the most recent sale price for GRAIG HOUSE of £530,000 on 19th November 2021. For the value to have increased from £530,000 to £584,691 over the four years and nine months to February 2025, the following assumptions must hold true:

• The value of GRAIG HOUSE has moved in line with the HPI for detached houses in the Vale of Glamorgan local authority area.
