CONWAY 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 CONWAY sales from June 2006 and December 2009 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 2006 sale was for 49% below the HPI. So the extrapolation line tracks at 49% below the HPI over time, until the December 2009 sale, where it rises to 1% above the HPI. The line then continues to track at 1% above the HPI.

What might CONWAY be worth now?

CONWAY might now be worth an estimated £514,473.

This is based on house price inflation of 71.5%, between December 2009 and December 2024, 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 71.5% inflationary increase is applied to the most recent sale price for CONWAY of £300,000 on 14th December 2009. For the value to have increased from £300,000 to £514,473 over the fifteen years to December 2024, the following assumptions must hold true:

• The value of CONWAY has moved in line with the HPI for detached houses in the Vale of Glamorgan local authority area.
• The December 2009 sale price of £300,000 represented a fair market value for the property.
• The size, condition, and specification of CONWAY has not materially changed since December 2009.
