10 PORTAL CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Wiltshire local authority area over time, sourced from the HPI. The four 10 PORTAL CLOSE sales between February 2003 and January 2020 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 July 2007 sale was for 40% above the HPI. So the extrapolation line tracks at 40% above the HPI over time, until the January 2020 sale, where it falls to 38% above the HPI. The line then continues to track at 38% above the HPI.

What might 10 PORTAL CLOSE be worth now?

10 PORTAL CLOSE might now be worth an estimated £715,718.

This is based on house price inflation of 22.3%, between January 2020 and December 2024, for detached houses, in the Wiltshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 22.3% inflationary increase is applied to the most recent sale price for 10 PORTAL CLOSE of £585,000 on 31st January 2020. For the value to have increased from £585,000 to £715,718 over the three years and one month to December 2024, the following assumptions must hold true:

• The value of 10 PORTAL CLOSE has moved in line with the HPI for detached houses in the Wiltshire local authority area.
• The January 2020 sale price of £585,000 represented a fair market value for the property.
• The size, condition, and specification of 10 PORTAL CLOSE has not materially changed since January 2020.
