20 HARPER ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Eastleigh local authority area over time, sourced from the HPI. The two 20 HARPER ROAD sales from March 2021 and October 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 March 2021 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the October 2025 sale, which was also at 24% below the HPI.

This is based on house price deflation of 0.5%, between October 2025 and May 2026, for detached houses, in the Eastleigh local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.5% deflationary decrease is applied to the most recent sale price for 20 HARPER ROAD of £400,000 on 15th October 2025. For the value to have decreased from £400,000 to £397,976 over the one year and five months to May 2026, the following assumptions must hold true:
