2 THE POLYGON Price Paid vs. HPI Average

The below graph shows the average detached house price in the Southampton local authority area over time, sourced from the HPI. The four 2 THE POLYGON sales between June 1996 and February 2018 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 April 2007 sale was for 72% above the HPI. So the extrapolation line tracks at 72% above the HPI over time, until the February 2018 sale, where it falls to 44% above the HPI. The line then continues to track at 44% above the HPI.

What might 2 THE POLYGON be worth now?

2 THE POLYGON might now be worth an estimated £613,008.

This is based on house price inflation of 22.6%, between February 2018 and December 2024, for detached houses, in the Southampton local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 22.6% inflationary increase is applied to the most recent sale price for 2 THE POLYGON of £500,000 on 13th February 2018. For the value to have increased from £500,000 to £613,008 over the five years and two months to December 2024, the following assumptions must hold true:

• The value of 2 THE POLYGON has moved in line with the HPI for detached houses in the Southampton local authority area.
• The February 2018 sale price of £500,000 represented a fair market value for the property.
• The size, condition, and specification of 2 THE POLYGON has not materially changed since February 2018.
