AROSFA Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The two AROSFA sales from June 1997 and November 2017 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 1997 sale was for 120% above the HPI. So the extrapolation line tracks at 120% above the HPI over time, until the November 2017 sale, where it falls to 86% above the HPI. The line then continues to track at 86% above the HPI.

What might AROSFA be worth now?

AROSFA might now be worth an estimated £445,550.

This is based on house price inflation of 44.4%, between November 2017 and April 2026, for terraced 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 44.4% inflationary increase is applied to the most recent sale price for AROSFA of £308,500 on 10th November 2017. For the value to have increased from £308,500 to £445,550 over the nine years and seven months to April 2026, the following assumptions must hold true:

• The value of AROSFA has moved in line with the HPI for terraced houses in the Vale of Glamorgan local authority area.
• The November 2017 sale price of £308,500 represented a fair market value for the property.
• The size, condition, and specification of AROSFA has not materially changed since November 2017.
