7 OLD SOUTH CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Harrow local authority area over time, sourced from the HPI. The two 7 OLD SOUTH CLOSE sales from December 2006 and August 2025 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 2006 sale was for 40% above the HPI. So the extrapolation line tracks at 40% above the HPI over time, until the August 2025 sale, where it falls to 25% above the HPI. The line then continues to track at 25% above the HPI.

What might 7 OLD SOUTH CLOSE be worth now?

This is based on house price deflation of 1.6%, between August 2025 and May 2026, for semi-detached houses, in the Harrow local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.6% deflationary decrease is applied to the most recent sale price for 7 OLD SOUTH CLOSE of £850,000 on 6th August 2025. For the value to have decreased from £850,000 to £836,098 over the one year and three months to May 2026, the following assumptions must hold true:
