18 DEEPWEIR 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 five 18 DEEPWEIR sales between April 2001 and February 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 December 2007 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the February 2017 sale, where it falls to 15% below the HPI. The line then continues to track at 15% below the HPI.

What might 18 DEEPWEIR be worth now?

18 DEEPWEIR might now be worth an estimated £250,077.

This is based on house price inflation of 50.7%, between February 2017 and December 2024, 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 50.7% inflationary increase is applied to the most recent sale price for 18 DEEPWEIR of £165,950 on 22nd February 2017. For the value to have increased from £165,950 to £250,077 over the six years and two months to December 2024, the following assumptions must hold true:

• The value of 18 DEEPWEIR has moved in line with the HPI for semi-detached houses in the Monmouthshire local authority area.
• The February 2017 sale price of £165,950 represented a fair market value for the property.
• The size, condition, and specification of 18 DEEPWEIR has not materially changed since February 2017.
