20 WATTS 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 two 20 WATTS CLOSE sales from June 1997 and September 1999 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 1997 sale was for 69% above the HPI. So the extrapolation line tracks at 69% above the HPI over time, until the September 1999 sale, where it falls to 40% above the HPI. The line then continues to track at 40% above the HPI.

What might 20 WATTS CLOSE be worth now?

This is based on house price inflation of 309.6%, between September 1999 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 309.6% inflationary increase is applied to the most recent sale price for 20 WATTS CLOSE of £84,500 on 10th September 1999. For the value to have increased from £84,500 to £346,119 over the 26 years and two months to July 2025, the following assumptions must hold true:
