20 ALDERNEY CLOSE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Southampton local authority area over time, sourced from the HPI. The three 20 ALDERNEY CLOSE sales between January 1997 and June 2010 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 October 2003 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the June 2010 sale, where it falls to 12% below the HPI. The line then continues to track at 12% below the HPI.

What might 20 ALDERNEY CLOSE be worth now?

This is based on house price inflation of 62.5%, between June 2010 and July 2025, for terraced 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 62.5% inflationary increase is applied to the most recent sale price for 20 ALDERNEY CLOSE of £134,000 on 23rd June 2010. For the value to have increased from £134,000 to £217,776 over the fourteen years and eleven months to July 2025, the following assumptions must hold true:

• The value of 20 ALDERNEY CLOSE has moved in line with the HPI for terraced houses in the Southampton local authority area.
